Quality controlsThe whole manufacturing process of Emmeti Alpert multilayer pipe is subject to strict controls carried out before during and after production from the raw materials through to the finished product

The production department and analytical laboratory carry out checks including the following

MFI (Melt Flow Index) Verify compliance of thepolymer raw materials to beused

INK Test Ensure that the strip of aluminium is clean

Dimensional control inproduction Automatic computerised control of pipe dimensions

Ball Test To ensure that there are noocclusions or deformations onthe inside of the pipe by usingcompressed air to pass a ballthrough the pipe

Enlargement Test Test performed both inproduction and in the laboratory to verify the quality of welds and the adhesion ofindividual layers

Peeling Test resistance todelamination between the innerlayer and the aluminium

Resistance to internalpressure Test resistance to a specificinternal pressure at 95 degC the pressure value is chosen as a function of the type of pipe (maximum diameter aluminium thickness) and the duration of the test (22h 165h 1000h) by referring to the relative regression curves

Thermal cycles Test on a system consistingof the pipe and fittings andsubjected to 5000 temperaturecycles (20 to 95 degC) of 30minutes each with a pressureof 10 bar

Pressure cycles Test on a system consistingof the pipe and fittings andsubjected to 10000 pressurecycles (from 1 to 30 bar) at23 degC with a frequency of05 Hz

Vibration test Vibration test on a systemconsisting of pipe andfittings which is subjected to330 alternating bending cycleswith an internal pressure of15 bar at room temperature

9

The advantagesof a complete systemGreater resistance to high temperaturesResistance to temperatures up to a maximum of 95 degC

Greater resistance to pressureResistance to pressures up to a maximum of 10 bar at a temperature of 70 degC for 50 years

Contained linear expansionThe linear expansion in relation to a variation in temperature is compa-rable with that of copper

Thermal insulationThe system is available with an insulating coating having the following fire reaction class CL-S1-d0 (EN 13501-1)

Low load lossesThe smooth surface of the pipe prevents limescale deposits and promotes the smooth flow of fluid thus considerably reducing pressure drops across the system

A higher water flow rate is attainableThe pipe has considerable resistance to mechanical erosion from solid particles that the water normally carries with it

Resistance to crushing and abrasionThis is due to the resistance of the aluminium layer and of the layers of PE-X used in the pipersquos construction

Impermeability to oxygenThe aluminium layer makes the Alpert pipe impermeable to gasses and therefore to oxygen that would cause corrosion of the systemrsquos metal components

Resistance to external chemical agentsAlpert pipes embedded in walls or buried under flooring can be due to their qualities placed in ldquoacidicrdquo and ldquoalkalirdquo environments

Complete resistance to electrochemical corrosionThis characteristic is obtained thanks to the materials used in the pipe construction and the fittings special dielectric element

Reduced weight and rapid installationThanks to its low specific weight and the ability to bend easily the Alpert pipe is extremely easy to installOnce bent into the desired position the pipe remains in that position in the same way a metallic pipe would doConnecting pipe fittings is quick and simple giving it a significant advan-tage over using traditional jointing methods

Fields of applicationThe Emmeti system consisting of Alpert multilayer pipes and Gerpex press fittings represents a modern and efficient solution used to build heating and sanitary systems with multilayer pipes made from not cross-linked with high resistance to high temperature polyethylene (PE-RT) and aluminium and special fittings

The fittings are available in two different versions press-fittings and screw-fittings The wide range of fittings and the various fastening op-tions make the system a complete and highly reliable product

The system is suitable for

bull Heating systemsbull Chilled water air-conditioning systemsbull Hydraulic systemsbull Compressed air systems ()

() An adequate filtering system has to be in place to avoid contact between compressor lubricant oil and O-rings included into the fittings

For the transport of other fluids please contact our Technical Supportservice for the suitable checks

10

Featuresof the system

Avoiding electrical voltageMultilayer Alpert pipes are made with a combination of aluminium and cross-linked polyethylene Both the inner and outer pipes wrap around the aluminium pipe effectively sealing itThis design eliminates any direct electrical contact with the metal part of the tubeIn addition at each joint the Gerpex multilayer pipes are isolated from the joint fitting by means of a plastic ringThis ensures that no direct current flow can be generated and avoids induced electrical voltage across the pipe system

Chemical resistanceThe chemical characteristics PE-RT make the Alpert pipe system resistantto of the following substances

bull Plaster concrete mortar and cementbull Disinfectants and cleaning agents complying with DVGW technical

sheet W291 and DIN 2000bull All natural materials containing drinking water according to DIN 2000bull Anti corrosives according to DIN 1988 part 4

Multilayer Alpert pipes must be protected from substances such as bitu-men grease solvents and mineral oilsFor compatibility with other chemical compounds reference should be made to the ISOTR 103581993 tables

Gerpex LBP and Gerpex pipe fittings must be protected with an appropriate coating if used in environments exposed to the danger of corrosion such as being laid in continuous flooring in spaces with permanent humidity in the presence of aggressive gases or concealed in direct contact with cement mortar or binders of lime

O-ring seals (in EPDM) are not compatible with petroleum products and therefore the use of lubricants derived from petroleum is prohibitedThe Gerpex system can be used with water and glycol mixtures to reach temperatures down to -10 degC

Heat insulationThe hot water distribution networks for domestic use or heating must be insulated in compliance with current legislationThe Alpert pipes pre-insulated with a sheath can be used in these sys-tems for the distribution of cold or refrigerated water (air conditioning systems) preventing the risk of condensate (after verification in compli-ance with the UNI EN ISO 12241- 2002 Standard)

Resistance to UV raysThe multilayer pipes must be protected from exposure to direct sunlight They therefore must be covered during transport or storage if they do not have the original packaging The Alpert pipes laid freely without protective pipes must be protected from prolonged exposure to solar rays (several months) by a coveringThe UV protection function of the Alpert pipes can only be performed by the insulating layer (insulated Alpert) by opaque sheets or by wrapping them in dark materials

No hygiene risksThe Alpert multilayer pipes are approved for use in installations with drinking water The lack of hygiene risks meaning suitability for hot and cold drinking water has been certified in compliance with the KTW Directives by the DVGW research institute and is subject to constant external controlThe use of the Alpert system in sanitary systems is ensured by certifi-cates of fitness for drinking water in compliance with current legislationThe Alpert multilayer pipes contribute considerably to preventing the proliferation of legionella thanks to the smooth surface of the internal pipe in PE-X which does not promote deposits

Press fittings Gerpex

FeaturesGerpex Emmeti press-fittings have been designed to be installed in conjunc-tion with electric or manual pressing devicesThis type of joint has become increasingly more popular due to its extremely simple and quick installation along with the high level of temperature and pressure resistanceThe jaw specific for every diameter of fittings compresses a stainless steel sleeve which secures the pipe onto the core of the fitting The hydraulic and mechanical sealing is guaranteed by the special profile of the fitting and the double O-ringAfter pressing the fitting produces a joint with maximum stability and dura-tion which makes it particularly suitable in embedded installations

Construction detailsThe stainless steel sleeve is connected to the fitting along with the blue plas-tic ringEach sleeve has the indication of the diameterThe plastic ring has four important functionsbull impedit prevents electric contact between the layer of aluminium of the

pipe and the brass body of the fitting thus preventing the risk of possible corrosion

bull it allows the installer to check via the sight holes that the pipe has been inserted fully into the fitting

bull it guides the correct positioning of the jaws around the sleevebull fixes the sleeve to the fitting

Installing the systemAll installation operations must be carried out at temperatures above -10 degC and below 45 degC to avoid any possible damage to the materialsIn case of temperatures below 0 degC store the materials (pipes and fit-tings) at a higher temperature before use

Surface mounted installationIn surface mounted installations in false ceilings in the gaps of dry wall systems (eg plasterboard) and in shafts the pipes must be adequately secured with suitable collars placed at a distance of no more than a cer-tain value that depends on the size of the pipe

It is preferable to use elbow unions to form curves on pipes with a diam-eter greater than 26 mmWhen bending the pipe you must also avoid putting pressure on the unions already installed and the distance between a union and the be-ginning of the bend must be greater than 5xoslash where Oslash is the external diameter of the pipe

L = 5 x Oslash

Thermal expansionDuring the installation phase pay particular attention to thermal expan-sion that can particularly affect multilayer pipes The elongation a pipe undergoes as a result of a variation in temperature can be calculated with the following formula

ΔL = α x L x ΔT

where

α is the coefficient of linear expansion equal to 0026 mmm K for insulated pipes

L is the initial length of the pipe (m)

ΔT is the temperature difference (K)

ExampleLength of pipe 12 mTemperature difference 50 KΔL = 0026 x 12 x 50 = 156 mm

L = Length (m)ΔT = Temperature difference (K)

ΔL = Longitudinal expansion (mm)

In surface mounted installations or installations in false ceilings and shafts longitudinal thermal expansion can be compensated for through careful arrangement of fixed and sliding brackets (points) depending on the type of installation thus providing suitable thermal expansion compensators

Where pipes are concealed or embedded in screed (laid in the floor) ther-mal expansion can be compensated for by creating an insulated curve at least every 10m (for example with an insulating foam sheath or by pass-ing the pipe through flexible tubing)

Note where the pipes are being used in radiant circuits (spiral or serpen-tine for underfloor heatingcooling) these guidelines do not apply

WhereLs = C x radic (Oslash x ΔL)Ls = Length of compensator (mm)Oslash = External diameter of pipe (mm)C = Material constant (for multilayer metal-plastic pipes C=33)

WithΔL = 156 mm (previous example)Oslash = 26 mmthe result will beLs = 33 x radic (26 x 156) = 665 mm

In order to guarantee the free movement of pipes in an installation inside a vertical shaft with horizontal branches the branches must have a mini-mum free length Ls and the passage through the side wall of the shaft should be free and the pipe protected with a sheath (Fig A and B)

In case the size of the shaft doesnrsquot allow for a compensator of length Ls the hole in the side wall should be increased in size and at the same time the tube should be protected with an insulating sheath of thickness Sge 15xΔL (Fig C)

System testingThe test must be carried out once the system is completed with the installation of the pipes and fittings before walling the concealed parts definitely

The system can be tested with potable clean and filtered water or compressed air without oilCompressed air is suitable in particularly low temperatures when there lies the risk of ice formation and in potable water distribution systems if too much time may elapse between the test and actual use with consequent hygienic risks due to the presence of stagnant water inside the pipes

Testing with waterThe test is carried out in two steps ndash leak test and hydraulic test ndash using pressure gauges with 01 bar resolution In case of a difference in tem-perature gt 10 K between the filling water and ambient temperature the test must be carried out at least 30 minutes after fillingAutomatic venting and drainage systems must be closed properly to prevent compromising the test The hydraulic test follows the leak test if the latter is successful

The leak test is carried out by filling the system with water keeping it at a pressure between 1 and 65 bar and visually checking each fitting and joint to detect any leak andor unpressed fitting andor joints that are not implemented correctly Warning The Gerpex fittings do not have the Leak Before Pressed function whereas the Gerpex LBP fittings do This function allows un-pressed fittings to be visually identified through water leaks that occur within a pressure range of 1 and 65 bar and is guaranteed and certified for Gerpex LBP fittings in combination with the Emmeti Gerpex RA and Emmeti Alpert pipes using Emmeti Gerpex equipment)

The hydraulic test for sanitary installations is carried out according to EN 806-4 with a test pressure of 11 bar (11 x MDP) which is to be maintained for at least 30 minutes MDP= Maximum Design Pressure = 10 bar

The hydraulic test for heating systems is carried out according to EN 14336 with a test pressure of 13 x Operating Pressure and in any case between 4 and 6 bar which is to be maintained for at least 120 minutesDetails are found in the two regulations

Testing with airThe test is carried out in two steps ndash leak test and load test ndash using pres-sure gauges with a 1 mbar resolution and an appropriate method of detec-tion (eg soapy water) The load test follows the leak test if the latteris successful

The leak test is carried out by filling the system with compressed air at a pressure between 110 and 150 mbar which is to be maintained for at least 30 minutes for volumes of up to 100 litres In the case of greater volumes the test duration must be increased by 10 minutes for every additional 100 litres

The load test is carried out by filling the system with compressed air at a pressure of 3 bar (up to dimension 50x4) or 1 bar (for dimensions ge 63x45) which is to be maintained for at least 30 minutes in the case of volumes of up to 100 litres In the case of greater volumes the test duration must be increased by 10 minutes for every additional 100 litres

At the end of the test the installer must fill and provide the customer with the relevant report which can be downloaded from the following link

Quality controlsThe whole manufacturing process of Emmeti Alpert multilayer pipe is subject to strict controls carried out before during and after production from the raw materials through to the finished product

The production department and analytical laboratory carry out checks including the following

MFI (Melt Flow Index) Verify compliance of thepolymer raw materials to beused

INK Test Ensure that the strip of aluminium is clean

Dimensional control inproduction Automatic computerised control of pipe dimensions

Ball Test To ensure that there are noocclusions or deformations onthe inside of the pipe by usingcompressed air to pass a ballthrough the pipe

Enlargement Test Test performed both inproduction and in the laboratory to verify the quality of welds and the adhesion ofindividual layers

Peeling Test resistance todelamination between the innerlayer and the aluminium

Resistance to internalpressure Test resistance to a specificinternal pressure at 95 degC the pressure value is chosen as a function of the type of pipe (maximum diameter aluminium thickness) and the duration of the test (22h 165h 1000h) by referring to the relative regression curves

Thermal cycles Test on a system consistingof the pipe and fittings andsubjected to 5000 temperaturecycles (20 to 95 degC) of 30minutes each with a pressureof 10 bar

Pressure cycles Test on a system consistingof the pipe and fittings andsubjected to 10000 pressurecycles (from 1 to 30 bar) at23 degC with a frequency of05 Hz

Vibration test Vibration test on a systemconsisting of pipe andfittings which is subjected to330 alternating bending cycleswith an internal pressure of15 bar at room temperature

9

The advantagesof a complete systemGreater resistance to high temperaturesResistance to temperatures up to a maximum of 95 degC

Greater resistance to pressureResistance to pressures up to a maximum of 10 bar at a temperature of 70 degC for 50 years

Contained linear expansionThe linear expansion in relation to a variation in temperature is compa-rable with that of copper

Thermal insulationThe system is available with an insulating coating having the following fire reaction class CL-S1-d0 (EN 13501-1)

Low load lossesThe smooth surface of the pipe prevents limescale deposits and promotes the smooth flow of fluid thus considerably reducing pressure drops across the system

A higher water flow rate is attainableThe pipe has considerable resistance to mechanical erosion from solid particles that the water normally carries with it

Resistance to crushing and abrasionThis is due to the resistance of the aluminium layer and of the layers of PE-X used in the pipersquos construction

Impermeability to oxygenThe aluminium layer makes the Alpert pipe impermeable to gasses and therefore to oxygen that would cause corrosion of the systemrsquos metal components

Resistance to external chemical agentsAlpert pipes embedded in walls or buried under flooring can be due to their qualities placed in ldquoacidicrdquo and ldquoalkalirdquo environments

Complete resistance to electrochemical corrosionThis characteristic is obtained thanks to the materials used in the pipe construction and the fittings special dielectric element

Reduced weight and rapid installationThanks to its low specific weight and the ability to bend easily the Alpert pipe is extremely easy to installOnce bent into the desired position the pipe remains in that position in the same way a metallic pipe would doConnecting pipe fittings is quick and simple giving it a significant advan-tage over using traditional jointing methods

Fields of applicationThe Emmeti system consisting of Alpert multilayer pipes and Gerpex press fittings represents a modern and efficient solution used to build heating and sanitary systems with multilayer pipes made from not cross-linked with high resistance to high temperature polyethylene (PE-RT) and aluminium and special fittings

The fittings are available in two different versions press-fittings and screw-fittings The wide range of fittings and the various fastening op-tions make the system a complete and highly reliable product

The system is suitable for

bull Heating systemsbull Chilled water air-conditioning systemsbull Hydraulic systemsbull Compressed air systems ()

() An adequate filtering system has to be in place to avoid contact between compressor lubricant oil and O-rings included into the fittings

For the transport of other fluids please contact our Technical Supportservice for the suitable checks

10

Featuresof the system

Avoiding electrical voltageMultilayer Alpert pipes are made with a combination of aluminium and cross-linked polyethylene Both the inner and outer pipes wrap around the aluminium pipe effectively sealing itThis design eliminates any direct electrical contact with the metal part of the tubeIn addition at each joint the Gerpex multilayer pipes are isolated from the joint fitting by means of a plastic ringThis ensures that no direct current flow can be generated and avoids induced electrical voltage across the pipe system

Chemical resistanceThe chemical characteristics PE-RT make the Alpert pipe system resistantto of the following substances

bull Plaster concrete mortar and cementbull Disinfectants and cleaning agents complying with DVGW technical

sheet W291 and DIN 2000bull All natural materials containing drinking water according to DIN 2000bull Anti corrosives according to DIN 1988 part 4

Multilayer Alpert pipes must be protected from substances such as bitu-men grease solvents and mineral oilsFor compatibility with other chemical compounds reference should be made to the ISOTR 103581993 tables

Gerpex LBP and Gerpex pipe fittings must be protected with an appropriate coating if used in environments exposed to the danger of corrosion such as being laid in continuous flooring in spaces with permanent humidity in the presence of aggressive gases or concealed in direct contact with cement mortar or binders of lime

O-ring seals (in EPDM) are not compatible with petroleum products and therefore the use of lubricants derived from petroleum is prohibitedThe Gerpex system can be used with water and glycol mixtures to reach temperatures down to -10 degC

Heat insulationThe hot water distribution networks for domestic use or heating must be insulated in compliance with current legislationThe Alpert pipes pre-insulated with a sheath can be used in these sys-tems for the distribution of cold or refrigerated water (air conditioning systems) preventing the risk of condensate (after verification in compli-ance with the UNI EN ISO 12241- 2002 Standard)

Resistance to UV raysThe multilayer pipes must be protected from exposure to direct sunlight They therefore must be covered during transport or storage if they do not have the original packaging The Alpert pipes laid freely without protective pipes must be protected from prolonged exposure to solar rays (several months) by a coveringThe UV protection function of the Alpert pipes can only be performed by the insulating layer (insulated Alpert) by opaque sheets or by wrapping them in dark materials

No hygiene risksThe Alpert multilayer pipes are approved for use in installations with drinking water The lack of hygiene risks meaning suitability for hot and cold drinking water has been certified in compliance with the KTW Directives by the DVGW research institute and is subject to constant external controlThe use of the Alpert system in sanitary systems is ensured by certifi-cates of fitness for drinking water in compliance with current legislationThe Alpert multilayer pipes contribute considerably to preventing the proliferation of legionella thanks to the smooth surface of the internal pipe in PE-X which does not promote deposits

Press fittings Gerpex

FeaturesGerpex Emmeti press-fittings have been designed to be installed in conjunc-tion with electric or manual pressing devicesThis type of joint has become increasingly more popular due to its extremely simple and quick installation along with the high level of temperature and pressure resistanceThe jaw specific for every diameter of fittings compresses a stainless steel sleeve which secures the pipe onto the core of the fitting The hydraulic and mechanical sealing is guaranteed by the special profile of the fitting and the double O-ringAfter pressing the fitting produces a joint with maximum stability and dura-tion which makes it particularly suitable in embedded installations

Construction detailsThe stainless steel sleeve is connected to the fitting along with the blue plas-tic ringEach sleeve has the indication of the diameterThe plastic ring has four important functionsbull impedit prevents electric contact between the layer of aluminium of the

pipe and the brass body of the fitting thus preventing the risk of possible corrosion

bull it allows the installer to check via the sight holes that the pipe has been inserted fully into the fitting

bull it guides the correct positioning of the jaws around the sleevebull fixes the sleeve to the fitting

Installing the systemAll installation operations must be carried out at temperatures above -10 degC and below 45 degC to avoid any possible damage to the materialsIn case of temperatures below 0 degC store the materials (pipes and fit-tings) at a higher temperature before use

Surface mounted installationIn surface mounted installations in false ceilings in the gaps of dry wall systems (eg plasterboard) and in shafts the pipes must be adequately secured with suitable collars placed at a distance of no more than a cer-tain value that depends on the size of the pipe

Surface embedded installationIn surface embedded installations the pipes must be suitably secured with ties and there must be a minimum distance between them of 80 cm on straight lengths and placed 30 cm before and after each bendFor this type of installation it is preferable to lay insulated pipe that has a foam sheath covering or pass the pipe through flexible tubing

Press fittings in laying concealed piping the press fittings must be pro-tected from corrosion that can result from contact with chemicals con-tained in plasters and mortarsIt is possible to use boxing adhesive tapes specifically adapted for such applications or coverings in an expanded plastic material that has been adequately sealed

It is preferable to use elbow unions to form curves on pipes with a diam-eter greater than 26 mmWhen bending the pipe you must also avoid putting pressure on the unions already installed and the distance between a union and the be-ginning of the bend must be greater than 5xoslash where Oslash is the external diameter of the pipe

L = 5 x Oslash

Thermal expansionDuring the installation phase pay particular attention to thermal expan-sion that can particularly affect multilayer pipes The elongation a pipe undergoes as a result of a variation in temperature can be calculated with the following formula

ΔL = α x L x ΔT

where

α is the coefficient of linear expansion equal to 0026 mmm K for insulated pipes

L is the initial length of the pipe (m)

ΔT is the temperature difference (K)

ExampleLength of pipe 12 mTemperature difference 50 KΔL = 0026 x 12 x 50 = 156 mm

L = Length (m)ΔT = Temperature difference (K)

ΔL = Longitudinal expansion (mm)

In surface mounted installations or installations in false ceilings and shafts longitudinal thermal expansion can be compensated for through careful arrangement of fixed and sliding brackets (points) depending on the type of installation thus providing suitable thermal expansion compensators

Where pipes are concealed or embedded in screed (laid in the floor) ther-mal expansion can be compensated for by creating an insulated curve at least every 10m (for example with an insulating foam sheath or by pass-ing the pipe through flexible tubing)

Note where the pipes are being used in radiant circuits (spiral or serpen-tine for underfloor heatingcooling) these guidelines do not apply

WhereLs = C x radic (Oslash x ΔL)Ls = Length of compensator (mm)Oslash = External diameter of pipe (mm)C = Material constant (for multilayer metal-plastic pipes C=33)

WithΔL = 156 mm (previous example)Oslash = 26 mmthe result will beLs = 33 x radic (26 x 156) = 665 mm

In order to guarantee the free movement of pipes in an installation inside a vertical shaft with horizontal branches the branches must have a mini-mum free length Ls and the passage through the side wall of the shaft should be free and the pipe protected with a sheath (Fig A and B)

Fig A Fig B Fig C

In case the size of the shaft doesnrsquot allow for a compensator of length Ls the hole in the side wall should be increased in size and at the same time the tube should be protected with an insulating sheath of thickness Sge 15xΔL (Fig C)

System testingThe test must be carried out once the system is completed with the installation of the pipes and fittings before walling the concealed parts definitely

The system can be tested with potable clean and filtered water or compressed air without oilCompressed air is suitable in particularly low temperatures when there lies the risk of ice formation and in potable water distribution systems if too much time may elapse between the test and actual use with consequent hygienic risks due to the presence of stagnant water inside the pipes

Testing with waterThe test is carried out in two steps ndash leak test and hydraulic test ndash using pressure gauges with 01 bar resolution In case of a difference in tem-perature gt 10 K between the filling water and ambient temperature the test must be carried out at least 30 minutes after fillingAutomatic venting and drainage systems must be closed properly to prevent compromising the test The hydraulic test follows the leak test if the latter is successful

The leak test is carried out by filling the system with water keeping it at a pressure between 1 and 65 bar and visually checking each fitting and joint to detect any leak andor unpressed fitting andor joints that are not implemented correctly Warning The Gerpex fittings do not have the Leak Before Pressed function whereas the Gerpex LBP fittings do This function allows un-pressed fittings to be visually identified through water leaks that occur within a pressure range of 1 and 65 bar and is guaranteed and certified for Gerpex LBP fittings in combination with the Emmeti Gerpex RA and Emmeti Alpert pipes using Emmeti Gerpex equipment)

The hydraulic test for sanitary installations is carried out according to EN 806-4 with a test pressure of 11 bar (11 x MDP) which is to be maintained for at least 30 minutes MDP= Maximum Design Pressure = 10 bar

The hydraulic test for heating systems is carried out according to EN 14336 with a test pressure of 13 x Operating Pressure and in any case between 4 and 6 bar which is to be maintained for at least 120 minutesDetails are found in the two regulations

Testing with airThe test is carried out in two steps ndash leak test and load test ndash using pres-sure gauges with a 1 mbar resolution and an appropriate method of detec-tion (eg soapy water) The load test follows the leak test if the latteris successful

The leak test is carried out by filling the system with compressed air at a pressure between 110 and 150 mbar which is to be maintained for at least 30 minutes for volumes of up to 100 litres In the case of greater volumes the test duration must be increased by 10 minutes for every additional 100 litres

The load test is carried out by filling the system with compressed air at a pressure of 3 bar (up to dimension 50x4) or 1 bar (for dimensions ge 63x45) which is to be maintained for at least 30 minutes in the case of volumes of up to 100 litres In the case of greater volumes the test duration must be increased by 10 minutes for every additional 100 litres

At the end of the test the installer must fill and provide the customer with the relevant report which can be downloaded from the following link

Quality controlsThe whole manufacturing process of Emmeti Alpert multilayer pipe is subject to strict controls carried out before during and after production from the raw materials through to the finished product

The production department and analytical laboratory carry out checks including the following

MFI (Melt Flow Index) Verify compliance of thepolymer raw materials to beused

INK Test Ensure that the strip of aluminium is clean

Dimensional control inproduction Automatic computerised control of pipe dimensions

Ball Test To ensure that there are noocclusions or deformations onthe inside of the pipe by usingcompressed air to pass a ballthrough the pipe

Enlargement Test Test performed both inproduction and in the laboratory to verify the quality of welds and the adhesion ofindividual layers

Peeling Test resistance todelamination between the innerlayer and the aluminium

Resistance to internalpressure Test resistance to a specificinternal pressure at 95 degC the pressure value is chosen as a function of the type of pipe (maximum diameter aluminium thickness) and the duration of the test (22h 165h 1000h) by referring to the relative regression curves

Thermal cycles Test on a system consistingof the pipe and fittings andsubjected to 5000 temperaturecycles (20 to 95 degC) of 30minutes each with a pressureof 10 bar

Pressure cycles Test on a system consistingof the pipe and fittings andsubjected to 10000 pressurecycles (from 1 to 30 bar) at23 degC with a frequency of05 Hz

Vibration test Vibration test on a systemconsisting of pipe andfittings which is subjected to330 alternating bending cycleswith an internal pressure of15 bar at room temperature

9

The advantagesof a complete systemGreater resistance to high temperaturesResistance to temperatures up to a maximum of 95 degC

Greater resistance to pressureResistance to pressures up to a maximum of 10 bar at a temperature of 70 degC for 50 years

Contained linear expansionThe linear expansion in relation to a variation in temperature is compa-rable with that of copper

Thermal insulationThe system is available with an insulating coating having the following fire reaction class CL-S1-d0 (EN 13501-1)

Low load lossesThe smooth surface of the pipe prevents limescale deposits and promotes the smooth flow of fluid thus considerably reducing pressure drops across the system

A higher water flow rate is attainableThe pipe has considerable resistance to mechanical erosion from solid particles that the water normally carries with it

Resistance to crushing and abrasionThis is due to the resistance of the aluminium layer and of the layers of PE-X used in the pipersquos construction

Impermeability to oxygenThe aluminium layer makes the Alpert pipe impermeable to gasses and therefore to oxygen that would cause corrosion of the systemrsquos metal components

Resistance to external chemical agentsAlpert pipes embedded in walls or buried under flooring can be due to their qualities placed in ldquoacidicrdquo and ldquoalkalirdquo environments

Complete resistance to electrochemical corrosionThis characteristic is obtained thanks to the materials used in the pipe construction and the fittings special dielectric element

Reduced weight and rapid installationThanks to its low specific weight and the ability to bend easily the Alpert pipe is extremely easy to installOnce bent into the desired position the pipe remains in that position in the same way a metallic pipe would doConnecting pipe fittings is quick and simple giving it a significant advan-tage over using traditional jointing methods

Fields of applicationThe Emmeti system consisting of Alpert multilayer pipes and Gerpex press fittings represents a modern and efficient solution used to build heating and sanitary systems with multilayer pipes made from not cross-linked with high resistance to high temperature polyethylene (PE-RT) and aluminium and special fittings

The fittings are available in two different versions press-fittings and screw-fittings The wide range of fittings and the various fastening op-tions make the system a complete and highly reliable product

The system is suitable for

bull Heating systemsbull Chilled water air-conditioning systemsbull Hydraulic systemsbull Compressed air systems ()

() An adequate filtering system has to be in place to avoid contact between compressor lubricant oil and O-rings included into the fittings

For the transport of other fluids please contact our Technical Supportservice for the suitable checks

10

Featuresof the system

Avoiding electrical voltageMultilayer Alpert pipes are made with a combination of aluminium and cross-linked polyethylene Both the inner and outer pipes wrap around the aluminium pipe effectively sealing itThis design eliminates any direct electrical contact with the metal part of the tubeIn addition at each joint the Gerpex multilayer pipes are isolated from the joint fitting by means of a plastic ringThis ensures that no direct current flow can be generated and avoids induced electrical voltage across the pipe system

Chemical resistanceThe chemical characteristics PE-RT make the Alpert pipe system resistantto of the following substances

bull Plaster concrete mortar and cementbull Disinfectants and cleaning agents complying with DVGW technical

sheet W291 and DIN 2000bull All natural materials containing drinking water according to DIN 2000bull Anti corrosives according to DIN 1988 part 4

Multilayer Alpert pipes must be protected from substances such as bitu-men grease solvents and mineral oilsFor compatibility with other chemical compounds reference should be made to the ISOTR 103581993 tables

Gerpex LBP and Gerpex pipe fittings must be protected with an appropriate coating if used in environments exposed to the danger of corrosion such as being laid in continuous flooring in spaces with permanent humidity in the presence of aggressive gases or concealed in direct contact with cement mortar or binders of lime

O-ring seals (in EPDM) are not compatible with petroleum products and therefore the use of lubricants derived from petroleum is prohibitedThe Gerpex system can be used with water and glycol mixtures to reach temperatures down to -10 degC

Heat insulationThe hot water distribution networks for domestic use or heating must be insulated in compliance with current legislationThe Alpert pipes pre-insulated with a sheath can be used in these sys-tems for the distribution of cold or refrigerated water (air conditioning systems) preventing the risk of condensate (after verification in compli-ance with the UNI EN ISO 12241- 2002 Standard)

Resistance to UV raysThe multilayer pipes must be protected from exposure to direct sunlight They therefore must be covered during transport or storage if they do not have the original packaging The Alpert pipes laid freely without protective pipes must be protected from prolonged exposure to solar rays (several months) by a coveringThe UV protection function of the Alpert pipes can only be performed by the insulating layer (insulated Alpert) by opaque sheets or by wrapping them in dark materials

No hygiene risksThe Alpert multilayer pipes are approved for use in installations with drinking water The lack of hygiene risks meaning suitability for hot and cold drinking water has been certified in compliance with the KTW Directives by the DVGW research institute and is subject to constant external controlThe use of the Alpert system in sanitary systems is ensured by certifi-cates of fitness for drinking water in compliance with current legislationThe Alpert multilayer pipes contribute considerably to preventing the proliferation of legionella thanks to the smooth surface of the internal pipe in PE-X which does not promote deposits

Press fittings Gerpex

FeaturesGerpex Emmeti press-fittings have been designed to be installed in conjunc-tion with electric or manual pressing devicesThis type of joint has become increasingly more popular due to its extremely simple and quick installation along with the high level of temperature and pressure resistanceThe jaw specific for every diameter of fittings compresses a stainless steel sleeve which secures the pipe onto the core of the fitting The hydraulic and mechanical sealing is guaranteed by the special profile of the fitting and the double O-ringAfter pressing the fitting produces a joint with maximum stability and dura-tion which makes it particularly suitable in embedded installations

Construction detailsThe stainless steel sleeve is connected to the fitting along with the blue plas-tic ringEach sleeve has the indication of the diameterThe plastic ring has four important functionsbull impedit prevents electric contact between the layer of aluminium of the

pipe and the brass body of the fitting thus preventing the risk of possible corrosion

bull it allows the installer to check via the sight holes that the pipe has been inserted fully into the fitting

bull it guides the correct positioning of the jaws around the sleevebull fixes the sleeve to the fitting

Compression fittingsFeaturesThe use of compression fittings makes easier the installation of the mul-tilayer system and moreover it requires very few toolsThe 24x19 thread allows the use of a single type of fittings in combination to four seals with different sizes thus rationalising stocksThe hydraulic seal is ensured by means of the system with three O-rings and a pipe-shaped toothed ogiveAll the fittings are equipped with a special PTFE ring that electrically isolates the pipe aluminium layer from the brass fitting

Construction detailsThe single body seal is supplied with it components (nut ogive adaptor)already assembled and ready for insertion into the pipeThe opening on the nut makes it possible to verify if the fitting has beeninserted all the way down to the Seat point

Installing the systemAll installation operations must be carried out at temperatures above -10 degC and below 45 degC to avoid any possible damage to the materialsIn case of temperatures below 0 degC store the materials (pipes and fit-tings) at a higher temperature before use

Surface mounted installationIn surface mounted installations in false ceilings in the gaps of dry wall systems (eg plasterboard) and in shafts the pipes must be adequately secured with suitable collars placed at a distance of no more than a cer-tain value that depends on the size of the pipe

It is preferable to use elbow unions to form curves on pipes with a diam-eter greater than 26 mmWhen bending the pipe you must also avoid putting pressure on the unions already installed and the distance between a union and the be-ginning of the bend must be greater than 5xoslash where Oslash is the external diameter of the pipe

L = 5 x Oslash

Thermal expansionDuring the installation phase pay particular attention to thermal expan-sion that can particularly affect multilayer pipes The elongation a pipe undergoes as a result of a variation in temperature can be calculated with the following formula

ΔL = α x L x ΔT

where

α is the coefficient of linear expansion equal to 0026 mmm K for insulated pipes

L is the initial length of the pipe (m)

ΔT is the temperature difference (K)

ExampleLength of pipe 12 mTemperature difference 50 KΔL = 0026 x 12 x 50 = 156 mm

L = Length (m)ΔT = Temperature difference (K)

ΔL = Longitudinal expansion (mm)

In surface mounted installations or installations in false ceilings and shafts longitudinal thermal expansion can be compensated for through careful arrangement of fixed and sliding brackets (points) depending on the type of installation thus providing suitable thermal expansion compensators

Where pipes are concealed or embedded in screed (laid in the floor) ther-mal expansion can be compensated for by creating an insulated curve at least every 10m (for example with an insulating foam sheath or by pass-ing the pipe through flexible tubing)

Note where the pipes are being used in radiant circuits (spiral or serpen-tine for underfloor heatingcooling) these guidelines do not apply

WhereLs = C x radic (Oslash x ΔL)Ls = Length of compensator (mm)Oslash = External diameter of pipe (mm)C = Material constant (for multilayer metal-plastic pipes C=33)

WithΔL = 156 mm (previous example)Oslash = 26 mmthe result will beLs = 33 x radic (26 x 156) = 665 mm

System testingThe test must be carried out once the system is completed with the installation of the pipes and fittings before walling the concealed parts definitely

The system can be tested with potable clean and filtered water or compressed air without oilCompressed air is suitable in particularly low temperatures when there lies the risk of ice formation and in potable water distribution systems if too much time may elapse between the test and actual use with consequent hygienic risks due to the presence of stagnant water inside the pipes

Testing with waterThe test is carried out in two steps ndash leak test and hydraulic test ndash using pressure gauges with 01 bar resolution In case of a difference in tem-perature gt 10 K between the filling water and ambient temperature the test must be carried out at least 30 minutes after fillingAutomatic venting and drainage systems must be closed properly to prevent compromising the test The hydraulic test follows the leak test if the latter is successful

The leak test is carried out by filling the system with water keeping it at a pressure between 1 and 65 bar and visually checking each fitting and joint to detect any leak andor unpressed fitting andor joints that are not implemented correctly Warning The Gerpex fittings do not have the Leak Before Pressed function whereas the Gerpex LBP fittings do This function allows un-pressed fittings to be visually identified through water leaks that occur within a pressure range of 1 and 65 bar and is guaranteed and certified for Gerpex LBP fittings in combination with the Emmeti Gerpex RA and Emmeti Alpert pipes using Emmeti Gerpex equipment)

The hydraulic test for sanitary installations is carried out according to EN 806-4 with a test pressure of 11 bar (11 x MDP) which is to be maintained for at least 30 minutes MDP= Maximum Design Pressure = 10 bar

The hydraulic test for heating systems is carried out according to EN 14336 with a test pressure of 13 x Operating Pressure and in any case between 4 and 6 bar which is to be maintained for at least 120 minutesDetails are found in the two regulations

Testing with airThe test is carried out in two steps ndash leak test and load test ndash using pres-sure gauges with a 1 mbar resolution and an appropriate method of detec-tion (eg soapy water) The load test follows the leak test if the latteris successful

The leak test is carried out by filling the system with compressed air at a pressure between 110 and 150 mbar which is to be maintained for at least 30 minutes for volumes of up to 100 litres In the case of greater volumes the test duration must be increased by 10 minutes for every additional 100 litres

The load test is carried out by filling the system with compressed air at a pressure of 3 bar (up to dimension 50x4) or 1 bar (for dimensions ge 63x45) which is to be maintained for at least 30 minutes in the case of volumes of up to 100 litres In the case of greater volumes the test duration must be increased by 10 minutes for every additional 100 litres

At the end of the test the installer must fill and provide the customer with the relevant report which can be downloaded from the following link

CuttingCut the multilayer pipe with a pipe cutter or shears verifying that the cut is perpendicular to the pipe axis

Calibration - FlaringCalibrate the cut end using the relevant calibrator which calibrates and flares the cut end of the pipe (Fig C)The operation is essential as it determines the correct internal diameter of the pipe and creates the rounded end that eases introduction of the fitting

Insertion the fittingInsert the fitting into the pipe fully home the transparent plastic ring al-lows verification of correct positioning (Fig D) Fig C Fig D

Completion of pressingRemove the pressing device and open the jaws again

Quality controlsThe whole manufacturing process of Emmeti Alpert multilayer pipe is subject to strict controls carried out before during and after production from the raw materials through to the finished product

The production department and analytical laboratory carry out checks including the following

MFI (Melt Flow Index) Verify compliance of thepolymer raw materials to beused

INK Test Ensure that the strip of aluminium is clean

Dimensional control inproduction Automatic computerised control of pipe dimensions

Ball Test To ensure that there are noocclusions or deformations onthe inside of the pipe by usingcompressed air to pass a ballthrough the pipe

Enlargement Test Test performed both inproduction and in the laboratory to verify the quality of welds and the adhesion ofindividual layers

Peeling Test resistance todelamination between the innerlayer and the aluminium

Resistance to internalpressure Test resistance to a specificinternal pressure at 95 degC the pressure value is chosen as a function of the type of pipe (maximum diameter aluminium thickness) and the duration of the test (22h 165h 1000h) by referring to the relative regression curves

Thermal cycles Test on a system consistingof the pipe and fittings andsubjected to 5000 temperaturecycles (20 to 95 degC) of 30minutes each with a pressureof 10 bar

Pressure cycles Test on a system consistingof the pipe and fittings andsubjected to 10000 pressurecycles (from 1 to 30 bar) at23 degC with a frequency of05 Hz

Vibration test Vibration test on a systemconsisting of pipe andfittings which is subjected to330 alternating bending cycleswith an internal pressure of15 bar at room temperature

9

The advantagesof a complete systemGreater resistance to high temperaturesResistance to temperatures up to a maximum of 95 degC

Greater resistance to pressureResistance to pressures up to a maximum of 10 bar at a temperature of 70 degC for 50 years

Contained linear expansionThe linear expansion in relation to a variation in temperature is compa-rable with that of copper

Thermal insulationThe system is available with an insulating coating having the following fire reaction class CL-S1-d0 (EN 13501-1)

Low load lossesThe smooth surface of the pipe prevents limescale deposits and promotes the smooth flow of fluid thus considerably reducing pressure drops across the system

A higher water flow rate is attainableThe pipe has considerable resistance to mechanical erosion from solid particles that the water normally carries with it

Resistance to crushing and abrasionThis is due to the resistance of the aluminium layer and of the layers of PE-X used in the pipersquos construction

Impermeability to oxygenThe aluminium layer makes the Alpert pipe impermeable to gasses and therefore to oxygen that would cause corrosion of the systemrsquos metal components

Resistance to external chemical agentsAlpert pipes embedded in walls or buried under flooring can be due to their qualities placed in ldquoacidicrdquo and ldquoalkalirdquo environments

Complete resistance to electrochemical corrosionThis characteristic is obtained thanks to the materials used in the pipe construction and the fittings special dielectric element

Reduced weight and rapid installationThanks to its low specific weight and the ability to bend easily the Alpert pipe is extremely easy to installOnce bent into the desired position the pipe remains in that position in the same way a metallic pipe would doConnecting pipe fittings is quick and simple giving it a significant advan-tage over using traditional jointing methods

Fields of applicationThe Emmeti system consisting of Alpert multilayer pipes and Gerpex press fittings represents a modern and efficient solution used to build heating and sanitary systems with multilayer pipes made from not cross-linked with high resistance to high temperature polyethylene (PE-RT) and aluminium and special fittings

The fittings are available in two different versions press-fittings and screw-fittings The wide range of fittings and the various fastening op-tions make the system a complete and highly reliable product

The system is suitable for

bull Heating systemsbull Chilled water air-conditioning systemsbull Hydraulic systemsbull Compressed air systems ()

() An adequate filtering system has to be in place to avoid contact between compressor lubricant oil and O-rings included into the fittings

For the transport of other fluids please contact our Technical Supportservice for the suitable checks

10

Featuresof the system

Avoiding electrical voltageMultilayer Alpert pipes are made with a combination of aluminium and cross-linked polyethylene Both the inner and outer pipes wrap around the aluminium pipe effectively sealing itThis design eliminates any direct electrical contact with the metal part of the tubeIn addition at each joint the Gerpex multilayer pipes are isolated from the joint fitting by means of a plastic ringThis ensures that no direct current flow can be generated and avoids induced electrical voltage across the pipe system

Chemical resistanceThe chemical characteristics PE-RT make the Alpert pipe system resistantto of the following substances

bull Plaster concrete mortar and cementbull Disinfectants and cleaning agents complying with DVGW technical

sheet W291 and DIN 2000bull All natural materials containing drinking water according to DIN 2000bull Anti corrosives according to DIN 1988 part 4

Multilayer Alpert pipes must be protected from substances such as bitu-men grease solvents and mineral oilsFor compatibility with other chemical compounds reference should be made to the ISOTR 103581993 tables

Gerpex LBP and Gerpex pipe fittings must be protected with an appropriate coating if used in environments exposed to the danger of corrosion such as being laid in continuous flooring in spaces with permanent humidity in the presence of aggressive gases or concealed in direct contact with cement mortar or binders of lime

O-ring seals (in EPDM) are not compatible with petroleum products and therefore the use of lubricants derived from petroleum is prohibitedThe Gerpex system can be used with water and glycol mixtures to reach temperatures down to -10 degC

Heat insulationThe hot water distribution networks for domestic use or heating must be insulated in compliance with current legislationThe Alpert pipes pre-insulated with a sheath can be used in these sys-tems for the distribution of cold or refrigerated water (air conditioning systems) preventing the risk of condensate (after verification in compli-ance with the UNI EN ISO 12241- 2002 Standard)

Resistance to UV raysThe multilayer pipes must be protected from exposure to direct sunlight They therefore must be covered during transport or storage if they do not have the original packaging The Alpert pipes laid freely without protective pipes must be protected from prolonged exposure to solar rays (several months) by a coveringThe UV protection function of the Alpert pipes can only be performed by the insulating layer (insulated Alpert) by opaque sheets or by wrapping them in dark materials

No hygiene risksThe Alpert multilayer pipes are approved for use in installations with drinking water The lack of hygiene risks meaning suitability for hot and cold drinking water has been certified in compliance with the KTW Directives by the DVGW research institute and is subject to constant external controlThe use of the Alpert system in sanitary systems is ensured by certifi-cates of fitness for drinking water in compliance with current legislationThe Alpert multilayer pipes contribute considerably to preventing the proliferation of legionella thanks to the smooth surface of the internal pipe in PE-X which does not promote deposits

Press fittings Gerpex

FeaturesGerpex Emmeti press-fittings have been designed to be installed in conjunc-tion with electric or manual pressing devicesThis type of joint has become increasingly more popular due to its extremely simple and quick installation along with the high level of temperature and pressure resistanceThe jaw specific for every diameter of fittings compresses a stainless steel sleeve which secures the pipe onto the core of the fitting The hydraulic and mechanical sealing is guaranteed by the special profile of the fitting and the double O-ringAfter pressing the fitting produces a joint with maximum stability and dura-tion which makes it particularly suitable in embedded installations

Construction detailsThe stainless steel sleeve is connected to the fitting along with the blue plas-tic ringEach sleeve has the indication of the diameterThe plastic ring has four important functionsbull impedit prevents electric contact between the layer of aluminium of the

pipe and the brass body of the fitting thus preventing the risk of possible corrosion

bull it allows the installer to check via the sight holes that the pipe has been inserted fully into the fitting

bull it guides the correct positioning of the jaws around the sleevebull fixes the sleeve to the fitting

Compression fittingsFeaturesThe use of compression fittings makes easier the installation of the mul-tilayer system and moreover it requires very few toolsThe 24x19 thread allows the use of a single type of fittings in combination to four seals with different sizes thus rationalising stocksThe hydraulic seal is ensured by means of the system with three O-rings and a pipe-shaped toothed ogiveAll the fittings are equipped with a special PTFE ring that electrically isolates the pipe aluminium layer from the brass fitting

Construction detailsThe single body seal is supplied with it components (nut ogive adaptor)already assembled and ready for insertion into the pipeThe opening on the nut makes it possible to verify if the fitting has beeninserted all the way down to the Seat point

It is preferable to use elbow unions to form curves on pipes with a diam-eter greater than 26 mmWhen bending the pipe you must also avoid putting pressure on the unions already installed and the distance between a union and the be-ginning of the bend must be greater than 5xoslash where Oslash is the external diameter of the pipe

L = 5 x Oslash

Thermal expansionDuring the installation phase pay particular attention to thermal expan-sion that can particularly affect multilayer pipes The elongation a pipe undergoes as a result of a variation in temperature can be calculated with the following formula

ΔL = α x L x ΔT

where

α is the coefficient of linear expansion equal to 0026 mmm K for insulated pipes

L is the initial length of the pipe (m)

ΔT is the temperature difference (K)

ExampleLength of pipe 12 mTemperature difference 50 KΔL = 0026 x 12 x 50 = 156 mm

L = Length (m)ΔT = Temperature difference (K)

ΔL = Longitudinal expansion (mm)

In surface mounted installations or installations in false ceilings and shafts longitudinal thermal expansion can be compensated for through careful arrangement of fixed and sliding brackets (points) depending on the type of installation thus providing suitable thermal expansion compensators

Where pipes are concealed or embedded in screed (laid in the floor) ther-mal expansion can be compensated for by creating an insulated curve at least every 10m (for example with an insulating foam sheath or by pass-ing the pipe through flexible tubing)

Note where the pipes are being used in radiant circuits (spiral or serpen-tine for underfloor heatingcooling) these guidelines do not apply

WhereLs = C x radic (Oslash x ΔL)Ls = Length of compensator (mm)Oslash = External diameter of pipe (mm)C = Material constant (for multilayer metal-plastic pipes C=33)

WithΔL = 156 mm (previous example)Oslash = 26 mmthe result will beLs = 33 x radic (26 x 156) = 665 mm

In order to guarantee the free movement of pipes in an installation inside a vertical shaft with horizontal branches the branches must have a mini-mum free length Ls and the passage through the side wall of the shaft should be free and the pipe protected with a sheath (Fig A and B)

System testingThe test must be carried out once the system is completed with the installation of the pipes and fittings before walling the concealed parts definitely

The system can be tested with potable clean and filtered water or compressed air without oilCompressed air is suitable in particularly low temperatures when there lies the risk of ice formation and in potable water distribution systems if too much time may elapse between the test and actual use with consequent hygienic risks due to the presence of stagnant water inside the pipes

Testing with waterThe test is carried out in two steps ndash leak test and hydraulic test ndash using pressure gauges with 01 bar resolution In case of a difference in tem-perature gt 10 K between the filling water and ambient temperature the test must be carried out at least 30 minutes after fillingAutomatic venting and drainage systems must be closed properly to prevent compromising the test The hydraulic test follows the leak test if the latter is successful

The leak test is carried out by filling the system with water keeping it at a pressure between 1 and 65 bar and visually checking each fitting and joint to detect any leak andor unpressed fitting andor joints that are not implemented correctly Warning The Gerpex fittings do not have the Leak Before Pressed function whereas the Gerpex LBP fittings do This function allows un-pressed fittings to be visually identified through water leaks that occur within a pressure range of 1 and 65 bar and is guaranteed and certified for Gerpex LBP fittings in combination with the Emmeti Gerpex RA and Emmeti Alpert pipes using Emmeti Gerpex equipment)

The hydraulic test for sanitary installations is carried out according to EN 806-4 with a test pressure of 11 bar (11 x MDP) which is to be maintained for at least 30 minutes MDP= Maximum Design Pressure = 10 bar

The hydraulic test for heating systems is carried out according to EN 14336 with a test pressure of 13 x Operating Pressure and in any case between 4 and 6 bar which is to be maintained for at least 120 minutesDetails are found in the two regulations

Testing with airThe test is carried out in two steps ndash leak test and load test ndash using pres-sure gauges with a 1 mbar resolution and an appropriate method of detec-tion (eg soapy water) The load test follows the leak test if the latteris successful

The leak test is carried out by filling the system with compressed air at a pressure between 110 and 150 mbar which is to be maintained for at least 30 minutes for volumes of up to 100 litres In the case of greater volumes the test duration must be increased by 10 minutes for every additional 100 litres

The load test is carried out by filling the system with compressed air at a pressure of 3 bar (up to dimension 50x4) or 1 bar (for dimensions ge 63x45) which is to be maintained for at least 30 minutes in the case of volumes of up to 100 litres In the case of greater volumes the test duration must be increased by 10 minutes for every additional 100 litres

At the end of the test the installer must fill and provide the customer with the relevant report which can be downloaded from the following link

Quality controlsThe whole manufacturing process of Emmeti Alpert multilayer pipe is subject to strict controls carried out before during and after production from the raw materials through to the finished product

The production department and analytical laboratory carry out checks including the following

MFI (Melt Flow Index) Verify compliance of thepolymer raw materials to beused

INK Test Ensure that the strip of aluminium is clean

Dimensional control inproduction Automatic computerised control of pipe dimensions

Ball Test To ensure that there are noocclusions or deformations onthe inside of the pipe by usingcompressed air to pass a ballthrough the pipe

Enlargement Test Test performed both inproduction and in the laboratory to verify the quality of welds and the adhesion ofindividual layers

Peeling Test resistance todelamination between the innerlayer and the aluminium

Resistance to internalpressure Test resistance to a specificinternal pressure at 95 degC the pressure value is chosen as a function of the type of pipe (maximum diameter aluminium thickness) and the duration of the test (22h 165h 1000h) by referring to the relative regression curves

Thermal cycles Test on a system consistingof the pipe and fittings andsubjected to 5000 temperaturecycles (20 to 95 degC) of 30minutes each with a pressureof 10 bar

Pressure cycles Test on a system consistingof the pipe and fittings andsubjected to 10000 pressurecycles (from 1 to 30 bar) at23 degC with a frequency of05 Hz

Vibration test Vibration test on a systemconsisting of pipe andfittings which is subjected to330 alternating bending cycleswith an internal pressure of15 bar at room temperature

9

The advantagesof a complete systemGreater resistance to high temperaturesResistance to temperatures up to a maximum of 95 degC

Greater resistance to pressureResistance to pressures up to a maximum of 10 bar at a temperature of 70 degC for 50 years

Contained linear expansionThe linear expansion in relation to a variation in temperature is compa-rable with that of copper

Thermal insulationThe system is available with an insulating coating having the following fire reaction class CL-S1-d0 (EN 13501-1)

Low load lossesThe smooth surface of the pipe prevents limescale deposits and promotes the smooth flow of fluid thus considerably reducing pressure drops across the system

A higher water flow rate is attainableThe pipe has considerable resistance to mechanical erosion from solid particles that the water normally carries with it

Resistance to crushing and abrasionThis is due to the resistance of the aluminium layer and of the layers of PE-X used in the pipersquos construction

Impermeability to oxygenThe aluminium layer makes the Alpert pipe impermeable to gasses and therefore to oxygen that would cause corrosion of the systemrsquos metal components

Resistance to external chemical agentsAlpert pipes embedded in walls or buried under flooring can be due to their qualities placed in ldquoacidicrdquo and ldquoalkalirdquo environments

Complete resistance to electrochemical corrosionThis characteristic is obtained thanks to the materials used in the pipe construction and the fittings special dielectric element

Reduced weight and rapid installationThanks to its low specific weight and the ability to bend easily the Alpert pipe is extremely easy to installOnce bent into the desired position the pipe remains in that position in the same way a metallic pipe would doConnecting pipe fittings is quick and simple giving it a significant advan-tage over using traditional jointing methods

Fields of applicationThe Emmeti system consisting of Alpert multilayer pipes and Gerpex press fittings represents a modern and efficient solution used to build heating and sanitary systems with multilayer pipes made from not cross-linked with high resistance to high temperature polyethylene (PE-RT) and aluminium and special fittings

The fittings are available in two different versions press-fittings and screw-fittings The wide range of fittings and the various fastening op-tions make the system a complete and highly reliable product

The system is suitable for

bull Heating systemsbull Chilled water air-conditioning systemsbull Hydraulic systemsbull Compressed air systems ()

() An adequate filtering system has to be in place to avoid contact between compressor lubricant oil and O-rings included into the fittings

For the transport of other fluids please contact our Technical Supportservice for the suitable checks

10

Featuresof the system

Avoiding electrical voltageMultilayer Alpert pipes are made with a combination of aluminium and cross-linked polyethylene Both the inner and outer pipes wrap around the aluminium pipe effectively sealing itThis design eliminates any direct electrical contact with the metal part of the tubeIn addition at each joint the Gerpex multilayer pipes are isolated from the joint fitting by means of a plastic ringThis ensures that no direct current flow can be generated and avoids induced electrical voltage across the pipe system

Chemical resistanceThe chemical characteristics PE-RT make the Alpert pipe system resistantto of the following substances

Multilayer Alpert pipes must be protected from substances such as bitu-men grease solvents and mineral oilsFor compatibility with other chemical compounds reference should be made to the ISOTR 103581993 tables

Gerpex LBP and Gerpex pipe fittings must be protected with an appropriate coating if used in environments exposed to the danger of corrosion such as being laid in continuous flooring in spaces with permanent humidity in the presence of aggressive gases or concealed in direct contact with cement mortar or binders of lime

O-ring seals (in EPDM) are not compatible with petroleum products and therefore the use of lubricants derived from petroleum is prohibitedThe Gerpex system can be used with water and glycol mixtures to reach temperatures down to -10 degC

Heat insulationThe hot water distribution networks for domestic use or heating must be insulated in compliance with current legislationThe Alpert pipes pre-insulated with a sheath can be used in these sys-tems for the distribution of cold or refrigerated water (air conditioning systems) preventing the risk of condensate (after verification in compli-ance with the UNI EN ISO 12241- 2002 Standard)

Resistance to UV raysThe multilayer pipes must be protected from exposure to direct sunlight They therefore must be covered during transport or storage if they do not have the original packaging The Alpert pipes laid freely without protective pipes must be protected from prolonged exposure to solar rays (several months) by a coveringThe UV protection function of the Alpert pipes can only be performed by the insulating layer (insulated Alpert) by opaque sheets or by wrapping them in dark materials

No hygiene risksThe Alpert multilayer pipes are approved for use in installations with drinking water The lack of hygiene risks meaning suitability for hot and cold drinking water has been certified in compliance with the KTW Directives by the DVGW research institute and is subject to constant external controlThe use of the Alpert system in sanitary systems is ensured by certifi-cates of fitness for drinking water in compliance with current legislationThe Alpert multilayer pipes contribute considerably to preventing the proliferation of legionella thanks to the smooth surface of the internal pipe in PE-X which does not promote deposits

Press fittings Gerpex

FeaturesGerpex Emmeti press-fittings have been designed to be installed in conjunc-tion with electric or manual pressing devicesThis type of joint has become increasingly more popular due to its extremely simple and quick installation along with the high level of temperature and pressure resistanceThe jaw specific for every diameter of fittings compresses a stainless steel sleeve which secures the pipe onto the core of the fitting The hydraulic and mechanical sealing is guaranteed by the special profile of the fitting and the double O-ringAfter pressing the fitting produces a joint with maximum stability and dura-tion which makes it particularly suitable in embedded installations

Construction detailsThe stainless steel sleeve is connected to the fitting along with the blue plas-tic ringEach sleeve has the indication of the diameterThe plastic ring has four important functionsbull impedit prevents electric contact between the layer of aluminium of the

pipe and the brass body of the fitting thus preventing the risk of possible corrosion

bull it allows the installer to check via the sight holes that the pipe has been inserted fully into the fitting

bull it guides the correct positioning of the jaws around the sleevebull fixes the sleeve to the fitting

Compression fittingsFeaturesThe use of compression fittings makes easier the installation of the mul-tilayer system and moreover it requires very few toolsThe 24x19 thread allows the use of a single type of fittings in combination to four seals with different sizes thus rationalising stocksThe hydraulic seal is ensured by means of the system with three O-rings and a pipe-shaped toothed ogiveAll the fittings are equipped with a special PTFE ring that electrically isolates the pipe aluminium layer from the brass fitting

Construction detailsThe single body seal is supplied with it components (nut ogive adaptor)already assembled and ready for insertion into the pipeThe opening on the nut makes it possible to verify if the fitting has beeninserted all the way down to the Seat point

It is preferable to use elbow unions to form curves on pipes with a diam-eter greater than 26 mmWhen bending the pipe you must also avoid putting pressure on the unions already installed and the distance between a union and the be-ginning of the bend must be greater than 5xoslash where Oslash is the external diameter of the pipe

L = 5 x Oslash

Oslash

Thermal expansionDuring the installation phase pay particular attention to thermal expan-sion that can particularly affect multilayer pipes The elongation a pipe undergoes as a result of a variation in temperature can be calculated with the following formula

ΔL = α x L x ΔT

where

α is the coefficient of linear expansion equal to 0026 mmm K for insulated pipes

L is the initial length of the pipe (m)

ΔT is the temperature difference (K)

ExampleLength of pipe 12 mTemperature difference 50 KΔL = 0026 x 12 x 50 = 156 mm

L = Length (m)ΔT = Temperature difference (K)

ΔL = Longitudinal expansion (mm)

In surface mounted installations or installations in false ceilings and shafts longitudinal thermal expansion can be compensated for through careful arrangement of fixed and sliding brackets (points) depending on the type of installation thus providing suitable thermal expansion compensators

Where pipes are concealed or embedded in screed (laid in the floor) ther-mal expansion can be compensated for by creating an insulated curve at least every 10m (for example with an insulating foam sheath or by pass-ing the pipe through flexible tubing)

Note where the pipes are being used in radiant circuits (spiral or serpen-tine for underfloor heatingcooling) these guidelines do not apply

WhereLs = C x radic (Oslash x ΔL)Ls = Length of compensator (mm)Oslash = External diameter of pipe (mm)C = Material constant (for multilayer metal-plastic pipes C=33)

WithΔL = 156 mm (previous example)Oslash = 26 mmthe result will beLs = 33 x radic (26 x 156) = 665 mm

In order to guarantee the free movement of pipes in an installation inside a vertical shaft with horizontal branches the branches must have a mini-mum free length Ls and the passage through the side wall of the shaft should be free and the pipe protected with a sheath (Fig A and B)

In case the size of the shaft doesnrsquot allow for a compensator of length Ls the hole in the side wall should be increased in size and at the same time the tube should be protected with an insulating sheath of thickness Sge 15xΔL (Fig C)

System testingThe test must be carried out once the system is completed with the installation of the pipes and fittings before walling the concealed parts definitely

The system can be tested with potable clean and filtered water or compressed air without oilCompressed air is suitable in particularly low temperatures when there lies the risk of ice formation and in potable water distribution systems if too much time may elapse between the test and actual use with consequent hygienic risks due to the presence of stagnant water inside the pipes

Testing with waterThe test is carried out in two steps ndash leak test and hydraulic test ndash using pressure gauges with 01 bar resolution In case of a difference in tem-perature gt 10 K between the filling water and ambient temperature the test must be carried out at least 30 minutes after fillingAutomatic venting and drainage systems must be closed properly to prevent compromising the test The hydraulic test follows the leak test if the latter is successful

The leak test is carried out by filling the system with water keeping it at a pressure between 1 and 65 bar and visually checking each fitting and joint to detect any leak andor unpressed fitting andor joints that are not implemented correctly Warning The Gerpex fittings do not have the Leak Before Pressed function whereas the Gerpex LBP fittings do This function allows un-pressed fittings to be visually identified through water leaks that occur within a pressure range of 1 and 65 bar and is guaranteed and certified for Gerpex LBP fittings in combination with the Emmeti Gerpex RA and Emmeti Alpert pipes using Emmeti Gerpex equipment)

The hydraulic test for sanitary installations is carried out according to EN 806-4 with a test pressure of 11 bar (11 x MDP) which is to be maintained for at least 30 minutes MDP= Maximum Design Pressure = 10 bar

The hydraulic test for heating systems is carried out according to EN 14336 with a test pressure of 13 x Operating Pressure and in any case between 4 and 6 bar which is to be maintained for at least 120 minutesDetails are found in the two regulations

Testing with airThe test is carried out in two steps ndash leak test and load test ndash using pres-sure gauges with a 1 mbar resolution and an appropriate method of detec-tion (eg soapy water) The load test follows the leak test if the latteris successful

The leak test is carried out by filling the system with compressed air at a pressure between 110 and 150 mbar which is to be maintained for at least 30 minutes for volumes of up to 100 litres In the case of greater volumes the test duration must be increased by 10 minutes for every additional 100 litres

The load test is carried out by filling the system with compressed air at a pressure of 3 bar (up to dimension 50x4) or 1 bar (for dimensions ge 63x45) which is to be maintained for at least 30 minutes in the case of volumes of up to 100 litres In the case of greater volumes the test duration must be increased by 10 minutes for every additional 100 litres

At the end of the test the installer must fill and provide the customer with the relevant report which can be downloaded from the following link

Quality controlsThe whole manufacturing process of Emmeti Alpert multilayer pipe is subject to strict controls carried out before during and after production from the raw materials through to the finished product

The production department and analytical laboratory carry out checks including the following

MFI (Melt Flow Index) Verify compliance of thepolymer raw materials to beused

INK Test Ensure that the strip of aluminium is clean

Dimensional control inproduction Automatic computerised control of pipe dimensions

Ball Test To ensure that there are noocclusions or deformations onthe inside of the pipe by usingcompressed air to pass a ballthrough the pipe

Enlargement Test Test performed both inproduction and in the laboratory to verify the quality of welds and the adhesion ofindividual layers

Peeling Test resistance todelamination between the innerlayer and the aluminium

Resistance to internalpressure Test resistance to a specificinternal pressure at 95 degC the pressure value is chosen as a function of the type of pipe (maximum diameter aluminium thickness) and the duration of the test (22h 165h 1000h) by referring to the relative regression curves

Thermal cycles Test on a system consistingof the pipe and fittings andsubjected to 5000 temperaturecycles (20 to 95 degC) of 30minutes each with a pressureof 10 bar

Pressure cycles Test on a system consistingof the pipe and fittings andsubjected to 10000 pressurecycles (from 1 to 30 bar) at23 degC with a frequency of05 Hz

Vibration test Vibration test on a systemconsisting of pipe andfittings which is subjected to330 alternating bending cycleswith an internal pressure of15 bar at room temperature

9

The advantagesof a complete systemGreater resistance to high temperaturesResistance to temperatures up to a maximum of 95 degC

Greater resistance to pressureResistance to pressures up to a maximum of 10 bar at a temperature of 70 degC for 50 years

Contained linear expansionThe linear expansion in relation to a variation in temperature is compa-rable with that of copper

Thermal insulationThe system is available with an insulating coating having the following fire reaction class CL-S1-d0 (EN 13501-1)

Low load lossesThe smooth surface of the pipe prevents limescale deposits and promotes the smooth flow of fluid thus considerably reducing pressure drops across the system

A higher water flow rate is attainableThe pipe has considerable resistance to mechanical erosion from solid particles that the water normally carries with it

Resistance to crushing and abrasionThis is due to the resistance of the aluminium layer and of the layers of PE-X used in the pipersquos construction

Impermeability to oxygenThe aluminium layer makes the Alpert pipe impermeable to gasses and therefore to oxygen that would cause corrosion of the systemrsquos metal components

Resistance to external chemical agentsAlpert pipes embedded in walls or buried under flooring can be due to their qualities placed in ldquoacidicrdquo and ldquoalkalirdquo environments

Complete resistance to electrochemical corrosionThis characteristic is obtained thanks to the materials used in the pipe construction and the fittings special dielectric element

Reduced weight and rapid installationThanks to its low specific weight and the ability to bend easily the Alpert pipe is extremely easy to installOnce bent into the desired position the pipe remains in that position in the same way a metallic pipe would doConnecting pipe fittings is quick and simple giving it a significant advan-tage over using traditional jointing methods

Fields of applicationThe Emmeti system consisting of Alpert multilayer pipes and Gerpex press fittings represents a modern and efficient solution used to build heating and sanitary systems with multilayer pipes made from not cross-linked with high resistance to high temperature polyethylene (PE-RT) and aluminium and special fittings

The fittings are available in two different versions press-fittings and screw-fittings The wide range of fittings and the various fastening op-tions make the system a complete and highly reliable product

The system is suitable for

Featuresof the system

Avoiding electrical voltageMultilayer Alpert pipes are made with a combination of aluminium and cross-linked polyethylene Both the inner and outer pipes wrap around the aluminium pipe effectively sealing itThis design eliminates any direct electrical contact with the metal part of the tubeIn addition at each joint the Gerpex multilayer pipes are isolated from the joint fitting by means of a plastic ringThis ensures that no direct current flow can be generated and avoids induced electrical voltage across the pipe system

Chemical resistanceThe chemical characteristics PE-RT make the Alpert pipe system resistantto of the following substances

bull Plaster concrete mortar and cementbull Disinfectants and cleaning agents complying with DVGW technical

sheet W291 and DIN 2000bull All natural materials containing drinking water according to DIN 2000bull Anti corrosives according to DIN 1988 part 4

Multilayer Alpert pipes must be protected from substances such as bitu-men grease solvents and mineral oilsFor compatibility with other chemical compounds reference should be made to the ISOTR 103581993 tables

Gerpex LBP and Gerpex pipe fittings must be protected with an appropriate coating if used in environments exposed to the danger of corrosion such as being laid in continuous flooring in spaces with permanent humidity in the presence of aggressive gases or concealed in direct contact with cement mortar or binders of lime

O-ring seals (in EPDM) are not compatible with petroleum products and therefore the use of lubricants derived from petroleum is prohibitedThe Gerpex system can be used with water and glycol mixtures to reach temperatures down to -10 degC

Heat insulationThe hot water distribution networks for domestic use or heating must be insulated in compliance with current legislationThe Alpert pipes pre-insulated with a sheath can be used in these sys-tems for the distribution of cold or refrigerated water (air conditioning systems) preventing the risk of condensate (after verification in compli-ance with the UNI EN ISO 12241- 2002 Standard)

Resistance to UV raysThe multilayer pipes must be protected from exposure to direct sunlight They therefore must be covered during transport or storage if they do not have the original packaging The Alpert pipes laid freely without protective pipes must be protected from prolonged exposure to solar rays (several months) by a coveringThe UV protection function of the Alpert pipes can only be performed by the insulating layer (insulated Alpert) by opaque sheets or by wrapping them in dark materials

No hygiene risksThe Alpert multilayer pipes are approved for use in installations with drinking water The lack of hygiene risks meaning suitability for hot and cold drinking water has been certified in compliance with the KTW Directives by the DVGW research institute and is subject to constant external controlThe use of the Alpert system in sanitary systems is ensured by certifi-cates of fitness for drinking water in compliance with current legislationThe Alpert multilayer pipes contribute considerably to preventing the proliferation of legionella thanks to the smooth surface of the internal pipe in PE-X which does not promote deposits

Press fittings Gerpex

FeaturesGerpex Emmeti press-fittings have been designed to be installed in conjunc-tion with electric or manual pressing devicesThis type of joint has become increasingly more popular due to its extremely simple and quick installation along with the high level of temperature and pressure resistanceThe jaw specific for every diameter of fittings compresses a stainless steel sleeve which secures the pipe onto the core of the fitting The hydraulic and mechanical sealing is guaranteed by the special profile of the fitting and the double O-ringAfter pressing the fitting produces a joint with maximum stability and dura-tion which makes it particularly suitable in embedded installations

Construction detailsThe stainless steel sleeve is connected to the fitting along with the blue plas-tic ringEach sleeve has the indication of the diameterThe plastic ring has four important functionsbull impedit prevents electric contact between the layer of aluminium of the

pipe and the brass body of the fitting thus preventing the risk of possible corrosion

bull it allows the installer to check via the sight holes that the pipe has been inserted fully into the fitting

bull it guides the correct positioning of the jaws around the sleevebull fixes the sleeve to the fitting

It is preferable to use elbow unions to form curves on pipes with a diam-eter greater than 26 mmWhen bending the pipe you must also avoid putting pressure on the unions already installed and the distance between a union and the be-ginning of the bend must be greater than 5xoslash where Oslash is the external diameter of the pipe

L = 5 x Oslash

Oslash

Thermal expansionDuring the installation phase pay particular attention to thermal expan-sion that can particularly affect multilayer pipes The elongation a pipe undergoes as a result of a variation in temperature can be calculated with the following formula

ΔL = α x L x ΔT

where

α is the coefficient of linear expansion equal to 0026 mmm K for insulated pipes

L is the initial length of the pipe (m)

ΔT is the temperature difference (K)

ExampleLength of pipe 12 mTemperature difference 50 KΔL = 0026 x 12 x 50 = 156 mm

L = Length (m)ΔT = Temperature difference (K)

ΔL = Longitudinal expansion (mm)

In surface mounted installations or installations in false ceilings and shafts longitudinal thermal expansion can be compensated for through careful arrangement of fixed and sliding brackets (points) depending on the type of installation thus providing suitable thermal expansion compensators

Where pipes are concealed or embedded in screed (laid in the floor) ther-mal expansion can be compensated for by creating an insulated curve at least every 10m (for example with an insulating foam sheath or by pass-ing the pipe through flexible tubing)

Note where the pipes are being used in radiant circuits (spiral or serpen-tine for underfloor heatingcooling) these guidelines do not apply

WhereLs = C x radic (Oslash x ΔL)Ls = Length of compensator (mm)Oslash = External diameter of pipe (mm)C = Material constant (for multilayer metal-plastic pipes C=33)

WithΔL = 156 mm (previous example)Oslash = 26 mmthe result will beLs = 33 x radic (26 x 156) = 665 mm

In order to guarantee the free movement of pipes in an installation inside a vertical shaft with horizontal branches the branches must have a mini-mum free length Ls and the passage through the side wall of the shaft should be free and the pipe protected with a sheath (Fig A and B)

In case the size of the shaft doesnrsquot allow for a compensator of length Ls the hole in the side wall should be increased in size and at the same time the tube should be protected with an insulating sheath of thickness Sge 15xΔL (Fig C)

System testingThe test must be carried out once the system is completed with the installation of the pipes and fittings before walling the concealed parts definitely

The system can be tested with potable clean and filtered water or compressed air without oilCompressed air is suitable in particularly low temperatures when there lies the risk of ice formation and in potable water distribution systems if too much time may elapse between the test and actual use with consequent hygienic risks due to the presence of stagnant water inside the pipes

Testing with waterThe test is carried out in two steps ndash leak test and hydraulic test ndash using pressure gauges with 01 bar resolution In case of a difference in tem-perature gt 10 K between the filling water and ambient temperature the test must be carried out at least 30 minutes after fillingAutomatic venting and drainage systems must be closed properly to prevent compromising the test The hydraulic test follows the leak test if the latter is successful

The leak test is carried out by filling the system with water keeping it at a pressure between 1 and 65 bar and visually checking each fitting and joint to detect any leak andor unpressed fitting andor joints that are not implemented correctly Warning The Gerpex fittings do not have the Leak Before Pressed function whereas the Gerpex LBP fittings do This function allows un-pressed fittings to be visually identified through water leaks that occur within a pressure range of 1 and 65 bar and is guaranteed and certified for Gerpex LBP fittings in combination with the Emmeti Gerpex RA and Emmeti Alpert pipes using Emmeti Gerpex equipment)

The hydraulic test for sanitary installations is carried out according to EN 806-4 with a test pressure of 11 bar (11 x MDP) which is to be maintained for at least 30 minutes MDP= Maximum Design Pressure = 10 bar

The hydraulic test for heating systems is carried out according to EN 14336 with a test pressure of 13 x Operating Pressure and in any case between 4 and 6 bar which is to be maintained for at least 120 minutesDetails are found in the two regulations

Testing with airThe test is carried out in two steps ndash leak test and load test ndash using pres-sure gauges with a 1 mbar resolution and an appropriate method of detec-tion (eg soapy water) The load test follows the leak test if the latteris successful

The leak test is carried out by filling the system with compressed air at a pressure between 110 and 150 mbar which is to be maintained for at least 30 minutes for volumes of up to 100 litres In the case of greater volumes the test duration must be increased by 10 minutes for every additional 100 litres

The load test is carried out by filling the system with compressed air at a pressure of 3 bar (up to dimension 50x4) or 1 bar (for dimensions ge 63x45) which is to be maintained for at least 30 minutes in the case of volumes of up to 100 litres In the case of greater volumes the test duration must be increased by 10 minutes for every additional 100 litres

At the end of the test the installer must fill and provide the customer with the relevant report which can be downloaded from the following link

Quality controlsThe whole manufacturing process of Emmeti Alpert multilayer pipe is subject to strict controls carried out before during and after production from the raw materials through to the finished product

The production department and analytical laboratory carry out checks including the following

MFI (Melt Flow Index) Verify compliance of thepolymer raw materials to beused

INK Test Ensure that the strip of aluminium is clean

Dimensional control inproduction Automatic computerised control of pipe dimensions

Ball Test To ensure that there are noocclusions or deformations onthe inside of the pipe by usingcompressed air to pass a ballthrough the pipe

Enlargement Test Test performed both inproduction and in the laboratory to verify the quality of welds and the adhesion ofindividual layers

Peeling Test resistance todelamination between the innerlayer and the aluminium

Resistance to internalpressure Test resistance to a specificinternal pressure at 95 degC the pressure value is chosen as a function of the type of pipe (maximum diameter aluminium thickness) and the duration of the test (22h 165h 1000h) by referring to the relative regression curves

Thermal cycles Test on a system consistingof the pipe and fittings andsubjected to 5000 temperaturecycles (20 to 95 degC) of 30minutes each with a pressureof 10 bar

Pressure cycles Test on a system consistingof the pipe and fittings andsubjected to 10000 pressurecycles (from 1 to 30 bar) at23 degC with a frequency of05 Hz

Vibration test Vibration test on a systemconsisting of pipe andfittings which is subjected to330 alternating bending cycleswith an internal pressure of15 bar at room temperature

9

The advantagesof a complete systemGreater resistance to high temperaturesResistance to temperatures up to a maximum of 95 degC

Greater resistance to pressureResistance to pressures up to a maximum of 10 bar at a temperature of 70 degC for 50 years

Contained linear expansionThe linear expansion in relation to a variation in temperature is compa-rable with that of copper

Thermal insulationThe system is available with an insulating coating having the following fire reaction class CL-S1-d0 (EN 13501-1)

Low load lossesThe smooth surface of the pipe prevents limescale deposits and promotes the smooth flow of fluid thus considerably reducing pressure drops across the system

A higher water flow rate is attainableThe pipe has considerable resistance to mechanical erosion from solid particles that the water normally carries with it

Resistance to crushing and abrasionThis is due to the resistance of the aluminium layer and of the layers of PE-X used in the pipersquos construction

Impermeability to oxygenThe aluminium layer makes the Alpert pipe impermeable to gasses and therefore to oxygen that would cause corrosion of the systemrsquos metal components

Resistance to external chemical agentsAlpert pipes embedded in walls or buried under flooring can be due to their qualities placed in ldquoacidicrdquo and ldquoalkalirdquo environments

Complete resistance to electrochemical corrosionThis characteristic is obtained thanks to the materials used in the pipe construction and the fittings special dielectric element

Reduced weight and rapid installationThanks to its low specific weight and the ability to bend easily the Alpert pipe is extremely easy to installOnce bent into the desired position the pipe remains in that position in the same way a metallic pipe would doConnecting pipe fittings is quick and simple giving it a significant advan-tage over using traditional jointing methods

Fields of applicationThe Emmeti system consisting of Alpert multilayer pipes and Gerpex press fittings represents a modern and efficient solution used to build heating and sanitary systems with multilayer pipes made from not cross-linked with high resistance to high temperature polyethylene (PE-RT) and aluminium and special fittings

The fittings are available in two different versions press-fittings and screw-fittings The wide range of fittings and the various fastening op-tions make the system a complete and highly reliable product

The system is suitable for

bull Heating systemsbull Chilled water air-conditioning systemsbull Hydraulic systemsbull Compressed air systems ()

() An adequate filtering system has to be in place to avoid contact between compressor lubricant oil and O-rings included into the fittings

Featuresof the system

Avoiding electrical voltageMultilayer Alpert pipes are made with a combination of aluminium and cross-linked polyethylene Both the inner and outer pipes wrap around the aluminium pipe effectively sealing itThis design eliminates any direct electrical contact with the metal part of the tubeIn addition at each joint the Gerpex multilayer pipes are isolated from the joint fitting by means of a plastic ringThis ensures that no direct current flow can be generated and avoids induced electrical voltage across the pipe system

Chemical resistanceThe chemical characteristics PE-RT make the Alpert pipe system resistantto of the following substances

bull Plaster concrete mortar and cementbull Disinfectants and cleaning agents complying with DVGW technical

sheet W291 and DIN 2000bull All natural materials containing drinking water according to DIN 2000bull Anti corrosives according to DIN 1988 part 4

Multilayer Alpert pipes must be protected from substances such as bitu-men grease solvents and mineral oilsFor compatibility with other chemical compounds reference should be made to the ISOTR 103581993 tables

Gerpex LBP and Gerpex pipe fittings must be protected with an appropriate coating if used in environments exposed to the danger of corrosion such as being laid in continuous flooring in spaces with permanent humidity in the presence of aggressive gases or concealed in direct contact with cement mortar or binders of lime

O-ring seals (in EPDM) are not compatible with petroleum products and therefore the use of lubricants derived from petroleum is prohibitedThe Gerpex system can be used with water and glycol mixtures to reach temperatures down to -10 degC

Heat insulationThe hot water distribution networks for domestic use or heating must be insulated in compliance with current legislationThe Alpert pipes pre-insulated with a sheath can be used in these sys-tems for the distribution of cold or refrigerated water (air conditioning systems) preventing the risk of condensate (after verification in compli-ance with the UNI EN ISO 12241- 2002 Standard)

Resistance to UV raysThe multilayer pipes must be protected from exposure to direct sunlight They therefore must be covered during transport or storage if they do not have the original packaging The Alpert pipes laid freely without protective pipes must be protected from prolonged exposure to solar rays (several months) by a coveringThe UV protection function of the Alpert pipes can only be performed by the insulating layer (insulated Alpert) by opaque sheets or by wrapping them in dark materials

No hygiene risksThe Alpert multilayer pipes are approved for use in installations with drinking water The lack of hygiene risks meaning suitability for hot and cold drinking water has been certified in compliance with the KTW Directives by the DVGW research institute and is subject to constant external controlThe use of the Alpert system in sanitary systems is ensured by certifi-cates of fitness for drinking water in compliance with current legislationThe Alpert multilayer pipes contribute considerably to preventing the proliferation of legionella thanks to the smooth surface of the internal pipe in PE-X which does not promote deposits

Press fittings Gerpex

FeaturesGerpex Emmeti press-fittings have been designed to be installed in conjunc-tion with electric or manual pressing devicesThis type of joint has become increasingly more popular due to its extremely simple and quick installation along with the high level of temperature and pressure resistanceThe jaw specific for every diameter of fittings compresses a stainless steel sleeve which secures the pipe onto the core of the fitting The hydraulic and mechanical sealing is guaranteed by the special profile of the fitting and the double O-ringAfter pressing the fitting produces a joint with maximum stability and dura-tion which makes it particularly suitable in embedded installations

Construction detailsThe stainless steel sleeve is connected to the fitting along with the blue plas-tic ringEach sleeve has the indication of the diameterThe plastic ring has four important functionsbull impedit prevents electric contact between the layer of aluminium of the

pipe and the brass body of the fitting thus preventing the risk of possible corrosion

bull it allows the installer to check via the sight holes that the pipe has been inserted fully into the fitting

bull it guides the correct positioning of the jaws around the sleevebull fixes the sleeve to the fitting

It is preferable to use elbow unions to form curves on pipes with a diam-eter greater than 26 mmWhen bending the pipe you must also avoid putting pressure on the unions already installed and the distance between a union and the be-ginning of the bend must be greater than 5xoslash where Oslash is the external diameter of the pipe

L = 5 x Oslash

Oslash

Thermal expansionDuring the installation phase pay particular attention to thermal expan-sion that can particularly affect multilayer pipes The elongation a pipe undergoes as a result of a variation in temperature can be calculated with the following formula

ΔL = α x L x ΔT

where

α is the coefficient of linear expansion equal to 0026 mmm K for insulated pipes

L is the initial length of the pipe (m)

ΔT is the temperature difference (K)

ExampleLength of pipe 12 mTemperature difference 50 KΔL = 0026 x 12 x 50 = 156 mm

L = Length (m)ΔT = Temperature difference (K)

ΔL = Longitudinal expansion (mm)

In surface mounted installations or installations in false ceilings and shafts longitudinal thermal expansion can be compensated for through careful arrangement of fixed and sliding brackets (points) depending on the type of installation thus providing suitable thermal expansion compensators

Where pipes are concealed or embedded in screed (laid in the floor) ther-mal expansion can be compensated for by creating an insulated curve at least every 10m (for example with an insulating foam sheath or by pass-ing the pipe through flexible tubing)

Note where the pipes are being used in radiant circuits (spiral or serpen-tine for underfloor heatingcooling) these guidelines do not apply

WhereLs = C x radic (Oslash x ΔL)Ls = Length of compensator (mm)Oslash = External diameter of pipe (mm)C = Material constant (for multilayer metal-plastic pipes C=33)

WithΔL = 156 mm (previous example)Oslash = 26 mmthe result will beLs = 33 x radic (26 x 156) = 665 mm

In order to guarantee the free movement of pipes in an installation inside a vertical shaft with horizontal branches the branches must have a mini-mum free length Ls and the passage through the side wall of the shaft should be free and the pipe protected with a sheath (Fig A and B)

Fig A Fig B Fig C

In case the size of the shaft doesnrsquot allow for a compensator of length Ls the hole in the side wall should be increased in size and at the same time the tube should be protected with an insulating sheath of thickness Sge 15xΔL (Fig C)

System testingThe test must be carried out once the system is completed with the installation of the pipes and fittings before walling the concealed parts definitely

The system can be tested with potable clean and filtered water or compressed air without oilCompressed air is suitable in particularly low temperatures when there lies the risk of ice formation and in potable water distribution systems if too much time may elapse between the test and actual use with consequent hygienic risks due to the presence of stagnant water inside the pipes

Testing with waterThe test is carried out in two steps ndash leak test and hydraulic test ndash using pressure gauges with 01 bar resolution In case of a difference in tem-perature gt 10 K between the filling water and ambient temperature the test must be carried out at least 30 minutes after fillingAutomatic venting and drainage systems must be closed properly to prevent compromising the test The hydraulic test follows the leak test if the latter is successful

The leak test is carried out by filling the system with water keeping it at a pressure between 1 and 65 bar and visually checking each fitting and joint to detect any leak andor unpressed fitting andor joints that are not implemented correctly Warning The Gerpex fittings do not have the Leak Before Pressed function whereas the Gerpex LBP fittings do This function allows un-pressed fittings to be visually identified through water leaks that occur within a pressure range of 1 and 65 bar and is guaranteed and certified for Gerpex LBP fittings in combination with the Emmeti Gerpex RA and Emmeti Alpert pipes using Emmeti Gerpex equipment)

The hydraulic test for sanitary installations is carried out according to EN 806-4 with a test pressure of 11 bar (11 x MDP) which is to be maintained for at least 30 minutes MDP= Maximum Design Pressure = 10 bar

The hydraulic test for heating systems is carried out according to EN 14336 with a test pressure of 13 x Operating Pressure and in any case between 4 and 6 bar which is to be maintained for at least 120 minutesDetails are found in the two regulations

Testing with airThe test is carried out in two steps ndash leak test and load test ndash using pres-sure gauges with a 1 mbar resolution and an appropriate method of detec-tion (eg soapy water) The load test follows the leak test if the latteris successful

The leak test is carried out by filling the system with compressed air at a pressure between 110 and 150 mbar which is to be maintained for at least 30 minutes for volumes of up to 100 litres In the case of greater volumes the test duration must be increased by 10 minutes for every additional 100 litres

The load test is carried out by filling the system with compressed air at a pressure of 3 bar (up to dimension 50x4) or 1 bar (for dimensions ge 63x45) which is to be maintained for at least 30 minutes in the case of volumes of up to 100 litres In the case of greater volumes the test duration must be increased by 10 minutes for every additional 100 litres

At the end of the test the installer must fill and provide the customer with the relevant report which can be downloaded from the following link

Quality controlsThe whole manufacturing process of Emmeti Alpert multilayer pipe is subject to strict controls carried out before during and after production from the raw materials through to the finished product

The production department and analytical laboratory carry out checks including the following

MFI (Melt Flow Index) Verify compliance of thepolymer raw materials to beused

INK Test Ensure that the strip of aluminium is clean

Dimensional control inproduction Automatic computerised control of pipe dimensions

Ball Test To ensure that there are noocclusions or deformations onthe inside of the pipe by usingcompressed air to pass a ballthrough the pipe

Enlargement Test Test performed both inproduction and in the laboratory to verify the quality of welds and the adhesion ofindividual layers

Peeling Test resistance todelamination between the innerlayer and the aluminium

Resistance to internalpressure Test resistance to a specificinternal pressure at 95 degC the pressure value is chosen as a function of the type of pipe (maximum diameter aluminium thickness) and the duration of the test (22h 165h 1000h) by referring to the relative regression curves

Thermal cycles Test on a system consistingof the pipe and fittings andsubjected to 5000 temperaturecycles (20 to 95 degC) of 30minutes each with a pressureof 10 bar

Pressure cycles Test on a system consistingof the pipe and fittings andsubjected to 10000 pressurecycles (from 1 to 30 bar) at23 degC with a frequency of05 Hz

Vibration test Vibration test on a systemconsisting of pipe andfittings which is subjected to330 alternating bending cycleswith an internal pressure of15 bar at room temperature

9

The advantagesof a complete systemGreater resistance to high temperaturesResistance to temperatures up to a maximum of 95 degC

Greater resistance to pressureResistance to pressures up to a maximum of 10 bar at a temperature of 70 degC for 50 years

Contained linear expansionThe linear expansion in relation to a variation in temperature is compa-rable with that of copper

Thermal insulationThe system is available with an insulating coating having the following fire reaction class CL-S1-d0 (EN 13501-1)

Low load lossesThe smooth surface of the pipe prevents limescale deposits and promotes the smooth flow of fluid thus considerably reducing pressure drops across the system

A higher water flow rate is attainableThe pipe has considerable resistance to mechanical erosion from solid particles that the water normally carries with it

Resistance to crushing and abrasionThis is due to the resistance of the aluminium layer and of the layers of PE-X used in the pipersquos construction

Impermeability to oxygenThe aluminium layer makes the Alpert pipe impermeable to gasses and therefore to oxygen that would cause corrosion of the systemrsquos metal components

Resistance to external chemical agentsAlpert pipes embedded in walls or buried under flooring can be due to their qualities placed in ldquoacidicrdquo and ldquoalkalirdquo environments

Complete resistance to electrochemical corrosionThis characteristic is obtained thanks to the materials used in the pipe construction and the fittings special dielectric element

Reduced weight and rapid installationThanks to its low specific weight and the ability to bend easily the Alpert pipe is extremely easy to installOnce bent into the desired position the pipe remains in that position in the same way a metallic pipe would doConnecting pipe fittings is quick and simple giving it a significant advan-tage over using traditional jointing methods

Fields of applicationThe Emmeti system consisting of Alpert multilayer pipes and Gerpex press fittings represents a modern and efficient solution used to build heating and sanitary systems with multilayer pipes made from not cross-linked with high resistance to high temperature polyethylene (PE-RT) and aluminium and special fittings

The fittings are available in two different versions press-fittings and screw-fittings The wide range of fittings and the various fastening op-tions make the system a complete and highly reliable product

The system is suitable for

bull Heating systemsbull Chilled water air-conditioning systemsbull Hydraulic systemsbull Compressed air systems ()

() An adequate filtering system has to be in place to avoid contact between compressor lubricant oil and O-rings included into the fittings

Featuresof the system

Avoiding electrical voltageMultilayer Alpert pipes are made with a combination of aluminium and cross-linked polyethylene Both the inner and outer pipes wrap around the aluminium pipe effectively sealing itThis design eliminates any direct electrical contact with the metal part of the tubeIn addition at each joint the Gerpex multilayer pipes are isolated from the joint fitting by means of a plastic ringThis ensures that no direct current flow can be generated and avoids induced electrical voltage across the pipe system

Chemical resistanceThe chemical characteristics PE-RT make the Alpert pipe system resistantto of the following substances

bull Plaster concrete mortar and cementbull Disinfectants and cleaning agents complying with DVGW technical

sheet W291 and DIN 2000bull All natural materials containing drinking water according to DIN 2000bull Anti corrosives according to DIN 1988 part 4

Multilayer Alpert pipes must be protected from substances such as bitu-men grease solvents and mineral oilsFor compatibility with other chemical compounds reference should be made to the ISOTR 103581993 tables

Gerpex LBP and Gerpex pipe fittings must be protected with an appropriate coating if used in environments exposed to the danger of corrosion such as being laid in continuous flooring in spaces with permanent humidity in the presence of aggressive gases or concealed in direct contact with cement mortar or binders of lime

O-ring seals (in EPDM) are not compatible with petroleum products and therefore the use of lubricants derived from petroleum is prohibitedThe Gerpex system can be used with water and glycol mixtures to reach temperatures down to -10 degC

Heat insulationThe hot water distribution networks for domestic use or heating must be insulated in compliance with current legislationThe Alpert pipes pre-insulated with a sheath can be used in these sys-tems for the distribution of cold or refrigerated water (air conditioning systems) preventing the risk of condensate (after verification in compli-ance with the UNI EN ISO 12241- 2002 Standard)

Resistance to UV raysThe multilayer pipes must be protected from exposure to direct sunlight They therefore must be covered during transport or storage if they do not have the original packaging The Alpert pipes laid freely without protective pipes must be protected from prolonged exposure to solar rays (several months) by a coveringThe UV protection function of the Alpert pipes can only be performed by the insulating layer (insulated Alpert) by opaque sheets or by wrapping them in dark materials

No hygiene risksThe Alpert multilayer pipes are approved for use in installations with drinking water The lack of hygiene risks meaning suitability for hot and cold drinking water has been certified in compliance with the KTW Directives by the DVGW research institute and is subject to constant external controlThe use of the Alpert system in sanitary systems is ensured by certifi-cates of fitness for drinking water in compliance with current legislationThe Alpert multilayer pipes contribute considerably to preventing the proliferation of legionella thanks to the smooth surface of the internal pipe in PE-X which does not promote deposits

Press fittings Gerpex

FeaturesGerpex Emmeti press-fittings have been designed to be installed in conjunc-tion with electric or manual pressing devicesThis type of joint has become increasingly more popular due to its extremely simple and quick installation along with the high level of temperature and pressure resistanceThe jaw specific for every diameter of fittings compresses a stainless steel sleeve which secures the pipe onto the core of the fitting The hydraulic and mechanical sealing is guaranteed by the special profile of the fitting and the double O-ringAfter pressing the fitting produces a joint with maximum stability and dura-tion which makes it particularly suitable in embedded installations

Construction detailsThe stainless steel sleeve is connected to the fitting along with the blue plas-tic ringEach sleeve has the indication of the diameterThe plastic ring has four important functionsbull impedit prevents electric contact between the layer of aluminium of the

pipe and the brass body of the fitting thus preventing the risk of possible corrosion

bull it allows the installer to check via the sight holes that the pipe has been inserted fully into the fitting

bull it guides the correct positioning of the jaws around the sleevebull fixes the sleeve to the fitting

It is preferable to use elbow unions to form curves on pipes with a diam-eter greater than 26 mmWhen bending the pipe you must also avoid putting pressure on the unions already installed and the distance between a union and the be-ginning of the bend must be greater than 5xoslash where Oslash is the external diameter of the pipe

L = 5 x Oslash

Oslash

Thermal expansionDuring the installation phase pay particular attention to thermal expan-sion that can particularly affect multilayer pipes The elongation a pipe undergoes as a result of a variation in temperature can be calculated with the following formula

ΔL = α x L x ΔT

where

α is the coefficient of linear expansion equal to 0026 mmm K for insulated pipes

L is the initial length of the pipe (m)

ΔT is the temperature difference (K)

ExampleLength of pipe 12 mTemperature difference 50 KΔL = 0026 x 12 x 50 = 156 mm

L = Length (m)ΔT = Temperature difference (K)

ΔL = Longitudinal expansion (mm)

In surface mounted installations or installations in false ceilings and shafts longitudinal thermal expansion can be compensated for through careful arrangement of fixed and sliding brackets (points) depending on the type of installation thus providing suitable thermal expansion compensators

Where pipes are concealed or embedded in screed (laid in the floor) ther-mal expansion can be compensated for by creating an insulated curve at least every 10m (for example with an insulating foam sheath or by pass-ing the pipe through flexible tubing)

Note where the pipes are being used in radiant circuits (spiral or serpen-tine for underfloor heatingcooling) these guidelines do not apply

WhereLs = C x radic (Oslash x ΔL)Ls = Length of compensator (mm)Oslash = External diameter of pipe (mm)C = Material constant (for multilayer metal-plastic pipes C=33)

WithΔL = 156 mm (previous example)Oslash = 26 mmthe result will beLs = 33 x radic (26 x 156) = 665 mm

In order to guarantee the free movement of pipes in an installation inside a vertical shaft with horizontal branches the branches must have a mini-mum free length Ls and the passage through the side wall of the shaft should be free and the pipe protected with a sheath (Fig A and B)

In case the size of the shaft doesnrsquot allow for a compensator of length Ls the hole in the side wall should be increased in size and at the same time the tube should be protected with an insulating sheath of thickness Sge 15xΔL (Fig C)

System testingThe test must be carried out once the system is completed with the installation of the pipes and fittings before walling the concealed parts definitely

The system can be tested with potable clean and filtered water or compressed air without oilCompressed air is suitable in particularly low temperatures when there lies the risk of ice formation and in potable water distribution systems if too much time may elapse between the test and actual use with consequent hygienic risks due to the presence of stagnant water inside the pipes

Testing with waterThe test is carried out in two steps ndash leak test and hydraulic test ndash using pressure gauges with 01 bar resolution In case of a difference in tem-perature gt 10 K between the filling water and ambient temperature the test must be carried out at least 30 minutes after fillingAutomatic venting and drainage systems must be closed properly to prevent compromising the test The hydraulic test follows the leak test if the latter is successful

The leak test is carried out by filling the system with water keeping it at a pressure between 1 and 65 bar and visually checking each fitting and joint to detect any leak andor unpressed fitting andor joints that are not implemented correctly Warning The Gerpex fittings do not have the Leak Before Pressed function whereas the Gerpex LBP fittings do This function allows un-pressed fittings to be visually identified through water leaks that occur within a pressure range of 1 and 65 bar and is guaranteed and certified for Gerpex LBP fittings in combination with the Emmeti Gerpex RA and Emmeti Alpert pipes using Emmeti Gerpex equipment)

The hydraulic test for sanitary installations is carried out according to EN 806-4 with a test pressure of 11 bar (11 x MDP) which is to be maintained for at least 30 minutes MDP= Maximum Design Pressure = 10 bar

The hydraulic test for heating systems is carried out according to EN 14336 with a test pressure of 13 x Operating Pressure and in any case between 4 and 6 bar which is to be maintained for at least 120 minutesDetails are found in the two regulations

Testing with airThe test is carried out in two steps ndash leak test and load test ndash using pres-sure gauges with a 1 mbar resolution and an appropriate method of detec-tion (eg soapy water) The load test follows the leak test if the latteris successful

The leak test is carried out by filling the system with compressed air at a pressure between 110 and 150 mbar which is to be maintained for at least 30 minutes for volumes of up to 100 litres In the case of greater volumes the test duration must be increased by 10 minutes for every additional 100 litres

The load test is carried out by filling the system with compressed air at a pressure of 3 bar (up to dimension 50x4) or 1 bar (for dimensions ge 63x45) which is to be maintained for at least 30 minutes in the case of volumes of up to 100 litres In the case of greater volumes the test duration must be increased by 10 minutes for every additional 100 litres

At the end of the test the installer must fill and provide the customer with the relevant report which can be downloaded from the following link

The advantagesof a complete systemGreater resistance to high temperaturesResistance to temperatures up to a maximum of 95 degC

Greater resistance to pressureResistance to pressures up to a maximum of 10 bar at a temperature of 70 degC for 50 years

Contained linear expansionThe linear expansion in relation to a variation in temperature is compa-rable with that of copper

Thermal insulationThe system is available with an insulating coating having the following fire reaction class CL-S1-d0 (EN 13501-1)

Low load lossesThe smooth surface of the pipe prevents limescale deposits and promotes the smooth flow of fluid thus considerably reducing pressure drops across the system

A higher water flow rate is attainableThe pipe has considerable resistance to mechanical erosion from solid particles that the water normally carries with it

Resistance to crushing and abrasionThis is due to the resistance of the aluminium layer and of the layers of PE-X used in the pipersquos construction

Impermeability to oxygenThe aluminium layer makes the Alpert pipe impermeable to gasses and therefore to oxygen that would cause corrosion of the systemrsquos metal components

Resistance to external chemical agentsAlpert pipes embedded in walls or buried under flooring can be due to their qualities placed in ldquoacidicrdquo and ldquoalkalirdquo environments

Complete resistance to electrochemical corrosionThis characteristic is obtained thanks to the materials used in the pipe construction and the fittings special dielectric element

Reduced weight and rapid installationThanks to its low specific weight and the ability to bend easily the Alpert pipe is extremely easy to installOnce bent into the desired position the pipe remains in that position in the same way a metallic pipe would doConnecting pipe fittings is quick and simple giving it a significant advan-tage over using traditional jointing methods

Fields of applicationThe Emmeti system consisting of Alpert multilayer pipes and Gerpex press fittings represents a modern and efficient solution used to build heating and sanitary systems with multilayer pipes made from not cross-linked with high resistance to high temperature polyethylene (PE-RT) and aluminium and special fittings

The fittings are available in two different versions press-fittings and screw-fittings The wide range of fittings and the various fastening op-tions make the system a complete and highly reliable product

The system is suitable for

bull Heating systemsbull Chilled water air-conditioning systemsbull Hydraulic systemsbull Compressed air systems ()

() An adequate filtering system has to be in place to avoid contact between compressor lubricant oil and O-rings included into the fittings

Featuresof the system

Avoiding electrical voltageMultilayer Alpert pipes are made with a combination of aluminium and cross-linked polyethylene Both the inner and outer pipes wrap around the aluminium pipe effectively sealing itThis design eliminates any direct electrical contact with the metal part of the tubeIn addition at each joint the Gerpex multilayer pipes are isolated from the joint fitting by means of a plastic ringThis ensures that no direct current flow can be generated and avoids induced electrical voltage across the pipe system

Chemical resistanceThe chemical characteristics PE-RT make the Alpert pipe system resistantto of the following substances

bull Plaster concrete mortar and cementbull Disinfectants and cleaning agents complying with DVGW technical

sheet W291 and DIN 2000bull All natural materials containing drinking water according to DIN 2000bull Anti corrosives according to DIN 1988 part 4

Multilayer Alpert pipes must be protected from substances such as bitu-men grease solvents and mineral oilsFor compatibility with other chemical compounds reference should be made to the ISOTR 103581993 tables

Gerpex LBP and Gerpex pipe fittings must be protected with an appropriate coating if used in environments exposed to the danger of corrosion such as being laid in continuous flooring in spaces with permanent humidity in the presence of aggressive gases or concealed in direct contact with cement mortar or binders of lime

O-ring seals (in EPDM) are not compatible with petroleum products and therefore the use of lubricants derived from petroleum is prohibitedThe Gerpex system can be used with water and glycol mixtures to reach temperatures down to -10 degC

Heat insulationThe hot water distribution networks for domestic use or heating must be insulated in compliance with current legislationThe Alpert pipes pre-insulated with a sheath can be used in these sys-tems for the distribution of cold or refrigerated water (air conditioning systems) preventing the risk of condensate (after verification in compli-ance with the UNI EN ISO 12241- 2002 Standard)

Resistance to UV raysThe multilayer pipes must be protected from exposure to direct sunlight They therefore must be covered during transport or storage if they do not have the original packaging The Alpert pipes laid freely without protective pipes must be protected from prolonged exposure to solar rays (several months) by a coveringThe UV protection function of the Alpert pipes can only be performed by the insulating layer (insulated Alpert) by opaque sheets or by wrapping them in dark materials

No hygiene risksThe Alpert multilayer pipes are approved for use in installations with drinking water The lack of hygiene risks meaning suitability for hot and cold drinking water has been certified in compliance with the KTW Directives by the DVGW research institute and is subject to constant external controlThe use of the Alpert system in sanitary systems is ensured by certifi-cates of fitness for drinking water in compliance with current legislationThe Alpert multilayer pipes contribute considerably to preventing the proliferation of legionella thanks to the smooth surface of the internal pipe in PE-X which does not promote deposits

Press fittings Gerpex

FeaturesGerpex Emmeti press-fittings have been designed to be installed in conjunc-tion with electric or manual pressing devicesThis type of joint has become increasingly more popular due to its extremely simple and quick installation along with the high level of temperature and pressure resistanceThe jaw specific for every diameter of fittings compresses a stainless steel sleeve which secures the pipe onto the core of the fitting The hydraulic and mechanical sealing is guaranteed by the special profile of the fitting and the double O-ringAfter pressing the fitting produces a joint with maximum stability and dura-tion which makes it particularly suitable in embedded installations

Construction detailsThe stainless steel sleeve is connected to the fitting along with the blue plas-tic ringEach sleeve has the indication of the diameterThe plastic ring has four important functionsbull impedit prevents electric contact between the layer of aluminium of the

pipe and the brass body of the fitting thus preventing the risk of possible corrosion

bull it allows the installer to check via the sight holes that the pipe has been inserted fully into the fitting

bull it guides the correct positioning of the jaws around the sleevebull fixes the sleeve to the fitting

It is preferable to use elbow unions to form curves on pipes with a diam-eter greater than 26 mmWhen bending the pipe you must also avoid putting pressure on the unions already installed and the distance between a union and the be-ginning of the bend must be greater than 5xoslash where Oslash is the external diameter of the pipe

L = 5 x Oslash

Oslash

Thermal expansionDuring the installation phase pay particular attention to thermal expan-sion that can particularly affect multilayer pipes The elongation a pipe undergoes as a result of a variation in temperature can be calculated with the following formula

ΔL = α x L x ΔT

where

α is the coefficient of linear expansion equal to 0026 mmm K for insulated pipes

L is the initial length of the pipe (m)

ΔT is the temperature difference (K)

ExampleLength of pipe 12 mTemperature difference 50 KΔL = 0026 x 12 x 50 = 156 mm

L = Length (m)ΔT = Temperature difference (K)

ΔL = Longitudinal expansion (mm)

In surface mounted installations or installations in false ceilings and shafts longitudinal thermal expansion can be compensated for through careful arrangement of fixed and sliding brackets (points) depending on the type of installation thus providing suitable thermal expansion compensators

Where pipes are concealed or embedded in screed (laid in the floor) ther-mal expansion can be compensated for by creating an insulated curve at least every 10m (for example with an insulating foam sheath or by pass-ing the pipe through flexible tubing)

Note where the pipes are being used in radiant circuits (spiral or serpen-tine for underfloor heatingcooling) these guidelines do not apply

WhereLs = C x radic (Oslash x ΔL)Ls = Length of compensator (mm)Oslash = External diameter of pipe (mm)C = Material constant (for multilayer metal-plastic pipes C=33)

WithΔL = 156 mm (previous example)Oslash = 26 mmthe result will beLs = 33 x radic (26 x 156) = 665 mm

In order to guarantee the free movement of pipes in an installation inside a vertical shaft with horizontal branches the branches must have a mini-mum free length Ls and the passage through the side wall of the shaft should be free and the pipe protected with a sheath (Fig A and B)

Fig A Fig B Fig C

In case the size of the shaft doesnrsquot allow for a compensator of length Ls the hole in the side wall should be increased in size and at the same time the tube should be protected with an insulating sheath of thickness Sge 15xΔL (Fig C)

System testingThe test must be carried out once the system is completed with the installation of the pipes and fittings before walling the concealed parts definitely

The system can be tested with potable clean and filtered water or compressed air without oilCompressed air is suitable in particularly low temperatures when there lies the risk of ice formation and in potable water distribution systems if too much time may elapse between the test and actual use with consequent hygienic risks due to the presence of stagnant water inside the pipes

Testing with waterThe test is carried out in two steps ndash leak test and hydraulic test ndash using pressure gauges with 01 bar resolution In case of a difference in tem-perature gt 10 K between the filling water and ambient temperature the test must be carried out at least 30 minutes after fillingAutomatic venting and drainage systems must be closed properly to prevent compromising the test The hydraulic test follows the leak test if the latter is successful

The leak test is carried out by filling the system with water keeping it at a pressure between 1 and 65 bar and visually checking each fitting and joint to detect any leak andor unpressed fitting andor joints that are not implemented correctly Warning The Gerpex fittings do not have the Leak Before Pressed function whereas the Gerpex LBP fittings do This function allows un-pressed fittings to be visually identified through water leaks that occur within a pressure range of 1 and 65 bar and is guaranteed and certified for Gerpex LBP fittings in combination with the Emmeti Gerpex RA and Emmeti Alpert pipes using Emmeti Gerpex equipment)

The hydraulic test for sanitary installations is carried out according to EN 806-4 with a test pressure of 11 bar (11 x MDP) which is to be maintained for at least 30 minutes MDP= Maximum Design Pressure = 10 bar

The hydraulic test for heating systems is carried out according to EN 14336 with a test pressure of 13 x Operating Pressure and in any case between 4 and 6 bar which is to be maintained for at least 120 minutesDetails are found in the two regulations

Testing with airThe test is carried out in two steps ndash leak test and load test ndash using pres-sure gauges with a 1 mbar resolution and an appropriate method of detec-tion (eg soapy water) The load test follows the leak test if the latteris successful

The leak test is carried out by filling the system with compressed air at a pressure between 110 and 150 mbar which is to be maintained for at least 30 minutes for volumes of up to 100 litres In the case of greater volumes the test duration must be increased by 10 minutes for every additional 100 litres

The load test is carried out by filling the system with compressed air at a pressure of 3 bar (up to dimension 50x4) or 1 bar (for dimensions ge 63x45) which is to be maintained for at least 30 minutes in the case of volumes of up to 100 litres In the case of greater volumes the test duration must be increased by 10 minutes for every additional 100 litres

At the end of the test the installer must fill and provide the customer with the relevant report which can be downloaded from the following link

Featuresof the system

Avoiding electrical voltageMultilayer Alpert pipes are made with a combination of aluminium and cross-linked polyethylene Both the inner and outer pipes wrap around the aluminium pipe effectively sealing itThis design eliminates any direct electrical contact with the metal part of the tubeIn addition at each joint the Gerpex multilayer pipes are isolated from the joint fitting by means of a plastic ringThis ensures that no direct current flow can be generated and avoids induced electrical voltage across the pipe system

Chemical resistanceThe chemical characteristics PE-RT make the Alpert pipe system resistantto of the following substances

bull Plaster concrete mortar and cementbull Disinfectants and cleaning agents complying with DVGW technical

sheet W291 and DIN 2000bull All natural materials containing drinking water according to DIN 2000bull Anti corrosives according to DIN 1988 part 4

Multilayer Alpert pipes must be protected from substances such as bitu-men grease solvents and mineral oilsFor compatibility with other chemical compounds reference should be made to the ISOTR 103581993 tables

Gerpex LBP and Gerpex pipe fittings must be protected with an appropriate coating if used in environments exposed to the danger of corrosion such as being laid in continuous flooring in spaces with permanent humidity in the presence of aggressive gases or concealed in direct contact with cement mortar or binders of lime

O-ring seals (in EPDM) are not compatible with petroleum products and therefore the use of lubricants derived from petroleum is prohibitedThe Gerpex system can be used with water and glycol mixtures to reach temperatures down to -10 degC

Heat insulationThe hot water distribution networks for domestic use or heating must be insulated in compliance with current legislationThe Alpert pipes pre-insulated with a sheath can be used in these sys-tems for the distribution of cold or refrigerated water (air conditioning systems) preventing the risk of condensate (after verification in compli-ance with the UNI EN ISO 12241- 2002 Standard)

Resistance to UV raysThe multilayer pipes must be protected from exposure to direct sunlight They therefore must be covered during transport or storage if they do not have the original packaging The Alpert pipes laid freely without protective pipes must be protected from prolonged exposure to solar rays (several months) by a coveringThe UV protection function of the Alpert pipes can only be performed by the insulating layer (insulated Alpert) by opaque sheets or by wrapping them in dark materials

No hygiene risksThe Alpert multilayer pipes are approved for use in installations with drinking water The lack of hygiene risks meaning suitability for hot and cold drinking water has been certified in compliance with the KTW Directives by the DVGW research institute and is subject to constant external controlThe use of the Alpert system in sanitary systems is ensured by certifi-cates of fitness for drinking water in compliance with current legislationThe Alpert multilayer pipes contribute considerably to preventing the proliferation of legionella thanks to the smooth surface of the internal pipe in PE-X which does not promote deposits

Press fittings Gerpex

FeaturesGerpex Emmeti press-fittings have been designed to be installed in conjunc-tion with electric or manual pressing devicesThis type of joint has become increasingly more popular due to its extremely simple and quick installation along with the high level of temperature and pressure resistanceThe jaw specific for every diameter of fittings compresses a stainless steel sleeve which secures the pipe onto the core of the fitting The hydraulic and mechanical sealing is guaranteed by the special profile of the fitting and the double O-ringAfter pressing the fitting produces a joint with maximum stability and dura-tion which makes it particularly suitable in embedded installations

Construction detailsThe stainless steel sleeve is connected to the fitting along with the blue plas-tic ringEach sleeve has the indication of the diameterThe plastic ring has four important functionsbull impedit prevents electric contact between the layer of aluminium of the

pipe and the brass body of the fitting thus preventing the risk of possible corrosion

bull it allows the installer to check via the sight holes that the pipe has been inserted fully into the fitting

bull it guides the correct positioning of the jaws around the sleevebull fixes the sleeve to the fitting

Compression fittingsFeaturesThe use of compression fittings makes easier the installation of the mul-tilayer system and moreover it requires very few toolsThe 24x19 thread allows the use of a single type of fittings in combination to four seals with different sizes thus rationalising stocksThe hydraulic seal is ensured by means of the system with three O-rings and a pipe-shaped toothed ogiveAll the fittings are equipped with a special PTFE ring that electrically isolates the pipe aluminium layer from the brass fitting

Construction detailsThe single body seal is supplied with it components (nut ogive adaptor)already assembled and ready for insertion into the pipeThe opening on the nut makes it possible to verify if the fitting has beeninserted all the way down to the Seat point

Thermal expansionDuring the installation phase pay particular attention to thermal expan-sion that can particularly affect multilayer pipes The elongation a pipe undergoes as a result of a variation in temperature can be calculated with the following formula

ΔL = α x L x ΔT

α is the coefficient of linear expansion equal to 0026 mmm K for insulated pipes

L is the initial length of the pipe (m)

ΔT is the temperature difference (K)

ExampleLength of pipe 12 mTemperature difference 50 KΔL = 0026 x 12 x 50 = 156 mm

L = Length (m)ΔT = Temperature difference (K)

ΔL = Longitudinal expansion (mm)

In surface mounted installations or installations in false ceilings and shafts longitudinal thermal expansion can be compensated for through careful arrangement of fixed and sliding brackets (points) depending on the type of installation thus providing suitable thermal expansion compensators

Where pipes are concealed or embedded in screed (laid in the floor) ther-mal expansion can be compensated for by creating an insulated curve at least every 10m (for example with an insulating foam sheath or by pass-ing the pipe through flexible tubing)

Note where the pipes are being used in radiant circuits (spiral or serpen-tine for underfloor heatingcooling) these guidelines do not apply

WhereLs = C x radic (Oslash x ΔL)Ls = Length of compensator (mm)Oslash = External diameter of pipe (mm)C = Material constant (for multilayer metal-plastic pipes C=33)

WithΔL = 156 mm (previous example)Oslash = 26 mmthe result will beLs = 33 x radic (26 x 156) = 665 mm

In order to guarantee the free movement of pipes in an installation inside a vertical shaft with horizontal branches the branches must have a mini-mum free length Ls and the passage through the side wall of the shaft should be free and the pipe protected with a sheath (Fig A and B)

In case the size of the shaft doesnrsquot allow for a compensator of length Ls the hole in the side wall should be increased in size and at the same time the tube should be protected with an insulating sheath of thickness Sge 15xΔL (Fig C)

System testingThe test must be carried out once the system is completed with the installation of the pipes and fittings before walling the concealed parts definitely

The system can be tested with potable clean and filtered water or compressed air without oilCompressed air is suitable in particularly low temperatures when there lies the risk of ice formation and in potable water distribution systems if too much time may elapse between the test and actual use with consequent hygienic risks due to the presence of stagnant water inside the pipes

Testing with waterThe test is carried out in two steps ndash leak test and hydraulic test ndash using pressure gauges with 01 bar resolution In case of a difference in tem-perature gt 10 K between the filling water and ambient temperature the test must be carried out at least 30 minutes after fillingAutomatic venting and drainage systems must be closed properly to prevent compromising the test The hydraulic test follows the leak test if the latter is successful

The leak test is carried out by filling the system with water keeping it at a pressure between 1 and 65 bar and visually checking each fitting and joint to detect any leak andor unpressed fitting andor joints that are not implemented correctly Warning The Gerpex fittings do not have the Leak Before Pressed function whereas the Gerpex LBP fittings do This function allows un-pressed fittings to be visually identified through water leaks that occur within a pressure range of 1 and 65 bar and is guaranteed and certified for Gerpex LBP fittings in combination with the Emmeti Gerpex RA and Emmeti Alpert pipes using Emmeti Gerpex equipment)

The hydraulic test for sanitary installations is carried out according to EN 806-4 with a test pressure of 11 bar (11 x MDP) which is to be maintained for at least 30 minutes MDP= Maximum Design Pressure = 10 bar

The hydraulic test for heating systems is carried out according to EN 14336 with a test pressure of 13 x Operating Pressure and in any case between 4 and 6 bar which is to be maintained for at least 120 minutesDetails are found in the two regulations

Testing with airThe test is carried out in two steps ndash leak test and load test ndash using pres-sure gauges with a 1 mbar resolution and an appropriate method of detec-tion (eg soapy water) The load test follows the leak test if the latteris successful

The leak test is carried out by filling the system with compressed air at a pressure between 110 and 150 mbar which is to be maintained for at least 30 minutes for volumes of up to 100 litres In the case of greater volumes the test duration must be increased by 10 minutes for every additional 100 litres

The load test is carried out by filling the system with compressed air at a pressure of 3 bar (up to dimension 50x4) or 1 bar (for dimensions ge 63x45) which is to be maintained for at least 30 minutes in the case of volumes of up to 100 litres In the case of greater volumes the test duration must be increased by 10 minutes for every additional 100 litres

At the end of the test the installer must fill and provide the customer with the relevant report which can be downloaded from the following link

Press fittings Gerpex

FeaturesGerpex Emmeti press-fittings have been designed to be installed in conjunc-tion with electric or manual pressing devicesThis type of joint has become increasingly more popular due to its extremely simple and quick installation along with the high level of temperature and pressure resistanceThe jaw specific for every diameter of fittings compresses a stainless steel sleeve which secures the pipe onto the core of the fitting The hydraulic and mechanical sealing is guaranteed by the special profile of the fitting and the double O-ringAfter pressing the fitting produces a joint with maximum stability and dura-tion which makes it particularly suitable in embedded installations

Construction detailsThe stainless steel sleeve is connected to the fitting along with the blue plas-tic ringEach sleeve has the indication of the diameterThe plastic ring has four important functionsbull impedit prevents electric contact between the layer of aluminium of the

pipe and the brass body of the fitting thus preventing the risk of possible corrosion

bull it allows the installer to check via the sight holes that the pipe has been inserted fully into the fitting

bull it guides the correct positioning of the jaws around the sleevebull fixes the sleeve to the fitting

Compression fittingsFeaturesThe use of compression fittings makes easier the installation of the mul-tilayer system and moreover it requires very few toolsThe 24x19 thread allows the use of a single type of fittings in combination to four seals with different sizes thus rationalising stocksThe hydraulic seal is ensured by means of the system with three O-rings and a pipe-shaped toothed ogiveAll the fittings are equipped with a special PTFE ring that electrically isolates the pipe aluminium layer from the brass fitting

Construction detailsThe single body seal is supplied with it components (nut ogive adaptor)already assembled and ready for insertion into the pipeThe opening on the nut makes it possible to verify if the fitting has beeninserted all the way down to the Seat point

It is preferable to use elbow unions to form curves on pipes with a diam-eter greater than 26 mmWhen bending the pipe you must also avoid putting pressure on the unions already installed and the distance between a union and the be-ginning of the bend must be greater than 5xoslash where Oslash is the external diameter of the pipe

L = 5 x Oslash

Thermal expansionDuring the installation phase pay particular attention to thermal expan-sion that can particularly affect multilayer pipes The elongation a pipe undergoes as a result of a variation in temperature can be calculated with the following formula

ΔL = α x L x ΔT

where

α is the coefficient of linear expansion equal to 0026 mmm K for insulated pipes

L is the initial length of the pipe (m)

ΔT is the temperature difference (K)

ExampleLength of pipe 12 mTemperature difference 50 KΔL = 0026 x 12 x 50 = 156 mm

L = Length (m)ΔT = Temperature difference (K)

ΔL = Longitudinal expansion (mm)

In surface mounted installations or installations in false ceilings and shafts longitudinal thermal expansion can be compensated for through careful arrangement of fixed and sliding brackets (points) depending on the type of installation thus providing suitable thermal expansion compensators

Where pipes are concealed or embedded in screed (laid in the floor) ther-mal expansion can be compensated for by creating an insulated curve at least every 10m (for example with an insulating foam sheath or by pass-ing the pipe through flexible tubing)

Note where the pipes are being used in radiant circuits (spiral or serpen-tine for underfloor heatingcooling) these guidelines do not apply

WhereLs = C x radic (Oslash x ΔL)Ls = Length of compensator (mm)Oslash = External diameter of pipe (mm)C = Material constant (for multilayer metal-plastic pipes C=33)

WithΔL = 156 mm (previous example)Oslash = 26 mmthe result will beLs = 33 x radic (26 x 156) = 665 mm

System testingThe test must be carried out once the system is completed with the installation of the pipes and fittings before walling the concealed parts definitely

The system can be tested with potable clean and filtered water or compressed air without oilCompressed air is suitable in particularly low temperatures when there lies the risk of ice formation and in potable water distribution systems if too much time may elapse between the test and actual use with consequent hygienic risks due to the presence of stagnant water inside the pipes

Testing with waterThe test is carried out in two steps ndash leak test and hydraulic test ndash using pressure gauges with 01 bar resolution In case of a difference in tem-perature gt 10 K between the filling water and ambient temperature the test must be carried out at least 30 minutes after fillingAutomatic venting and drainage systems must be closed properly to prevent compromising the test The hydraulic test follows the leak test if the latter is successful

The leak test is carried out by filling the system with water keeping it at a pressure between 1 and 65 bar and visually checking each fitting and joint to detect any leak andor unpressed fitting andor joints that are not implemented correctly Warning The Gerpex fittings do not have the Leak Before Pressed function whereas the Gerpex LBP fittings do This function allows un-pressed fittings to be visually identified through water leaks that occur within a pressure range of 1 and 65 bar and is guaranteed and certified for Gerpex LBP fittings in combination with the Emmeti Gerpex RA and Emmeti Alpert pipes using Emmeti Gerpex equipment)

The hydraulic test for sanitary installations is carried out according to EN 806-4 with a test pressure of 11 bar (11 x MDP) which is to be maintained for at least 30 minutes MDP= Maximum Design Pressure = 10 bar

The hydraulic test for heating systems is carried out according to EN 14336 with a test pressure of 13 x Operating Pressure and in any case between 4 and 6 bar which is to be maintained for at least 120 minutesDetails are found in the two regulations

Testing with airThe test is carried out in two steps ndash leak test and load test ndash using pres-sure gauges with a 1 mbar resolution and an appropriate method of detec-tion (eg soapy water) The load test follows the leak test if the latteris successful

The leak test is carried out by filling the system with compressed air at a pressure between 110 and 150 mbar which is to be maintained for at least 30 minutes for volumes of up to 100 litres In the case of greater volumes the test duration must be increased by 10 minutes for every additional 100 litres

The load test is carried out by filling the system with compressed air at a pressure of 3 bar (up to dimension 50x4) or 1 bar (for dimensions ge 63x45) which is to be maintained for at least 30 minutes in the case of volumes of up to 100 litres In the case of greater volumes the test duration must be increased by 10 minutes for every additional 100 litres

At the end of the test the installer must fill and provide the customer with the relevant report which can be downloaded from the following link

CuttingCut the multilayer pipe with a pipe cutter or shears verifying that the cut is perpendicular to the pipe axis

Calibration - FlaringCalibrate the cut end using the relevant calibrator which calibrates and flares the cut end of the pipe (Fig C)The operation is essential as it determines the correct internal diameter of the pipe and creates the rounded end that eases introduction of the fitting

Insertion the fittingInsert the fitting into the pipe fully home the transparent plastic ring al-lows verification of correct positioning (Fig D) Fig C Fig D

Completion of pressingRemove the pressing device and open the jaws again

Press fittings Gerpex

FeaturesGerpex Emmeti press-fittings have been designed to be installed in conjunc-tion with electric or manual pressing devicesThis type of joint has become increasingly more popular due to its extremely simple and quick installation along with the high level of temperature and pressure resistanceThe jaw specific for every diameter of fittings compresses a stainless steel sleeve which secures the pipe onto the core of the fitting The hydraulic and mechanical sealing is guaranteed by the special profile of the fitting and the double O-ringAfter pressing the fitting produces a joint with maximum stability and dura-tion which makes it particularly suitable in embedded installations

Construction detailsThe stainless steel sleeve is connected to the fitting along with the blue plas-tic ringEach sleeve has the indication of the diameterThe plastic ring has four important functionsbull impedit prevents electric contact between the layer of aluminium of the

pipe and the brass body of the fitting thus preventing the risk of possible corrosion

bull it allows the installer to check via the sight holes that the pipe has been inserted fully into the fitting

bull it guides the correct positioning of the jaws around the sleevebull fixes the sleeve to the fitting

Compression fittingsFeaturesThe use of compression fittings makes easier the installation of the mul-tilayer system and moreover it requires very few toolsThe 24x19 thread allows the use of a single type of fittings in combination to four seals with different sizes thus rationalising stocksThe hydraulic seal is ensured by means of the system with three O-rings and a pipe-shaped toothed ogiveAll the fittings are equipped with a special PTFE ring that electrically isolates the pipe aluminium layer from the brass fitting

Construction detailsThe single body seal is supplied with it components (nut ogive adaptor)already assembled and ready for insertion into the pipeThe opening on the nut makes it possible to verify if the fitting has beeninserted all the way down to the Seat point

Installing the systemAll installation operations must be carried out at temperatures above -10 degC and below 45 degC to avoid any possible damage to the materialsIn case of temperatures below 0 degC store the materials (pipes and fit-tings) at a higher temperature before use

Surface mounted installationIn surface mounted installations in false ceilings in the gaps of dry wall systems (eg plasterboard) and in shafts the pipes must be adequately secured with suitable collars placed at a distance of no more than a cer-tain value that depends on the size of the pipe

Surface embedded installationIn surface embedded installations the pipes must be suitably secured with ties and there must be a minimum distance between them of 80 cm on straight lengths and placed 30 cm before and after each bendFor this type of installation it is preferable to lay insulated pipe that has a foam sheath covering or pass the pipe through flexible tubing

Press fittings in laying concealed piping the press fittings must be pro-tected from corrosion that can result from contact with chemicals con-tained in plasters and mortarsIt is possible to use boxing adhesive tapes specifically adapted for such applications or coverings in an expanded plastic material that has been adequately sealed

It is preferable to use elbow unions to form curves on pipes with a diam-eter greater than 26 mmWhen bending the pipe you must also avoid putting pressure on the unions already installed and the distance between a union and the be-ginning of the bend must be greater than 5xoslash where Oslash is the external diameter of the pipe

L = 5 x Oslash

Thermal expansionDuring the installation phase pay particular attention to thermal expan-sion that can particularly affect multilayer pipes The elongation a pipe undergoes as a result of a variation in temperature can be calculated with the following formula

ΔL = α x L x ΔT

where

α is the coefficient of linear expansion equal to 0026 mmm K for insulated pipes

L is the initial length of the pipe (m)

ΔT is the temperature difference (K)

ExampleLength of pipe 12 mTemperature difference 50 KΔL = 0026 x 12 x 50 = 156 mm

L = Length (m)ΔT = Temperature difference (K)

ΔL = Longitudinal expansion (mm)

In surface mounted installations or installations in false ceilings and shafts longitudinal thermal expansion can be compensated for through careful arrangement of fixed and sliding brackets (points) depending on the type of installation thus providing suitable thermal expansion compensators

Where pipes are concealed or embedded in screed (laid in the floor) ther-mal expansion can be compensated for by creating an insulated curve at least every 10m (for example with an insulating foam sheath or by pass-ing the pipe through flexible tubing)

Note where the pipes are being used in radiant circuits (spiral or serpen-tine for underfloor heatingcooling) these guidelines do not apply

WhereLs = C x radic (Oslash x ΔL)Ls = Length of compensator (mm)Oslash = External diameter of pipe (mm)C = Material constant (for multilayer metal-plastic pipes C=33)

WithΔL = 156 mm (previous example)Oslash = 26 mmthe result will beLs = 33 x radic (26 x 156) = 665 mm

In order to guarantee the free movement of pipes in an installation inside a vertical shaft with horizontal branches the branches must have a mini-mum free length Ls and the passage through the side wall of the shaft should be free and the pipe protected with a sheath (Fig A and B)

In case the size of the shaft doesnrsquot allow for a compensator of length Ls the hole in the side wall should be increased in size and at the same time the tube should be protected with an insulating sheath of thickness Sge 15xΔL (Fig C)

System testingThe test must be carried out once the system is completed with the installation of the pipes and fittings before walling the concealed parts definitely

The system can be tested with potable clean and filtered water or compressed air without oilCompressed air is suitable in particularly low temperatures when there lies the risk of ice formation and in potable water distribution systems if too much time may elapse between the test and actual use with consequent hygienic risks due to the presence of stagnant water inside the pipes

Testing with waterThe test is carried out in two steps ndash leak test and hydraulic test ndash using pressure gauges with 01 bar resolution In case of a difference in tem-perature gt 10 K between the filling water and ambient temperature the test must be carried out at least 30 minutes after fillingAutomatic venting and drainage systems must be closed properly to prevent compromising the test The hydraulic test follows the leak test if the latter is successful

The leak test is carried out by filling the system with water keeping it at a pressure between 1 and 65 bar and visually checking each fitting and joint to detect any leak andor unpressed fitting andor joints that are not implemented correctly Warning The Gerpex fittings do not have the Leak Before Pressed function whereas the Gerpex LBP fittings do This function allows un-pressed fittings to be visually identified through water leaks that occur within a pressure range of 1 and 65 bar and is guaranteed and certified for Gerpex LBP fittings in combination with the Emmeti Gerpex RA and Emmeti Alpert pipes using Emmeti Gerpex equipment)

The hydraulic test for sanitary installations is carried out according to EN 806-4 with a test pressure of 11 bar (11 x MDP) which is to be maintained for at least 30 minutes MDP= Maximum Design Pressure = 10 bar

The hydraulic test for heating systems is carried out according to EN 14336 with a test pressure of 13 x Operating Pressure and in any case between 4 and 6 bar which is to be maintained for at least 120 minutesDetails are found in the two regulations

Testing with airThe test is carried out in two steps ndash leak test and load test ndash using pres-sure gauges with a 1 mbar resolution and an appropriate method of detec-tion (eg soapy water) The load test follows the leak test if the latteris successful

The leak test is carried out by filling the system with compressed air at a pressure between 110 and 150 mbar which is to be maintained for at least 30 minutes for volumes of up to 100 litres In the case of greater volumes the test duration must be increased by 10 minutes for every additional 100 litres

The load test is carried out by filling the system with compressed air at a pressure of 3 bar (up to dimension 50x4) or 1 bar (for dimensions ge 63x45) which is to be maintained for at least 30 minutes in the case of volumes of up to 100 litres In the case of greater volumes the test duration must be increased by 10 minutes for every additional 100 litres

At the end of the test the installer must fill and provide the customer with the relevant report which can be downloaded from the following link

Press fittings Gerpex

FeaturesGerpex Emmeti press-fittings have been designed to be installed in conjunc-tion with electric or manual pressing devicesThis type of joint has become increasingly more popular due to its extremely simple and quick installation along with the high level of temperature and pressure resistanceThe jaw specific for every diameter of fittings compresses a stainless steel sleeve which secures the pipe onto the core of the fitting The hydraulic and mechanical sealing is guaranteed by the special profile of the fitting and the double O-ringAfter pressing the fitting produces a joint with maximum stability and dura-tion which makes it particularly suitable in embedded installations

Construction detailsThe stainless steel sleeve is connected to the fitting along with the blue plas-tic ringEach sleeve has the indication of the diameterThe plastic ring has four important functionsbull impedit prevents electric contact between the layer of aluminium of the

pipe and the brass body of the fitting thus preventing the risk of possible corrosion

bull it allows the installer to check via the sight holes that the pipe has been inserted fully into the fitting

bull it guides the correct positioning of the jaws around the sleevebull fixes the sleeve to the fitting

Compression fittingsFeaturesThe use of compression fittings makes easier the installation of the mul-tilayer system and moreover it requires very few toolsThe 24x19 thread allows the use of a single type of fittings in combination to four seals with different sizes thus rationalising stocksThe hydraulic seal is ensured by means of the system with three O-rings and a pipe-shaped toothed ogiveAll the fittings are equipped with a special PTFE ring that electrically isolates the pipe aluminium layer from the brass fitting

Construction detailsThe single body seal is supplied with it components (nut ogive adaptor)already assembled and ready for insertion into the pipeThe opening on the nut makes it possible to verify if the fitting has beeninserted all the way down to the Seat point

Installing the systemAll installation operations must be carried out at temperatures above -10 degC and below 45 degC to avoid any possible damage to the materialsIn case of temperatures below 0 degC store the materials (pipes and fit-tings) at a higher temperature before use

Surface mounted installationIn surface mounted installations in false ceilings in the gaps of dry wall systems (eg plasterboard) and in shafts the pipes must be adequately secured with suitable collars placed at a distance of no more than a cer-tain value that depends on the size of the pipe

Surface embedded installationIn surface embedded installations the pipes must be suitably secured with ties and there must be a minimum distance between them of 80 cm on straight lengths and placed 30 cm before and after each bendFor this type of installation it is preferable to lay insulated pipe that has a foam sheath covering or pass the pipe through flexible tubing

Press fittings in laying concealed piping the press fittings must be pro-tected from corrosion that can result from contact with chemicals con-tained in plasters and mortarsIt is possible to use boxing adhesive tapes specifically adapted for such applications or coverings in an expanded plastic material that has been adequately sealed

It is preferable to use elbow unions to form curves on pipes with a diam-eter greater than 26 mmWhen bending the pipe you must also avoid putting pressure on the unions already installed and the distance between a union and the be-ginning of the bend must be greater than 5xoslash where Oslash is the external diameter of the pipe

L = 5 x Oslash

Thermal expansionDuring the installation phase pay particular attention to thermal expan-sion that can particularly affect multilayer pipes The elongation a pipe undergoes as a result of a variation in temperature can be calculated with the following formula

ΔL = α x L x ΔT

where

α is the coefficient of linear expansion equal to 0026 mmm K for insulated pipes

L is the initial length of the pipe (m)

ΔT is the temperature difference (K)

ExampleLength of pipe 12 mTemperature difference 50 KΔL = 0026 x 12 x 50 = 156 mm

L = Length (m)ΔT = Temperature difference (K)

ΔL = Longitudinal expansion (mm)

In surface mounted installations or installations in false ceilings and shafts longitudinal thermal expansion can be compensated for through careful arrangement of fixed and sliding brackets (points) depending on the type of installation thus providing suitable thermal expansion compensators

Where pipes are concealed or embedded in screed (laid in the floor) ther-mal expansion can be compensated for by creating an insulated curve at least every 10m (for example with an insulating foam sheath or by pass-ing the pipe through flexible tubing)

Note where the pipes are being used in radiant circuits (spiral or serpen-tine for underfloor heatingcooling) these guidelines do not apply

WhereLs = C x radic (Oslash x ΔL)Ls = Length of compensator (mm)Oslash = External diameter of pipe (mm)C = Material constant (for multilayer metal-plastic pipes C=33)

WithΔL = 156 mm (previous example)Oslash = 26 mmthe result will beLs = 33 x radic (26 x 156) = 665 mm

In order to guarantee the free movement of pipes in an installation inside a vertical shaft with horizontal branches the branches must have a mini-mum free length Ls and the passage through the side wall of the shaft should be free and the pipe protected with a sheath (Fig A and B)

Fig A Fig B Fig C

In case the size of the shaft doesnrsquot allow for a compensator of length Ls the hole in the side wall should be increased in size and at the same time the tube should be protected with an insulating sheath of thickness Sge 15xΔL (Fig C)

System testingThe test must be carried out once the system is completed with the installation of the pipes and fittings before walling the concealed parts definitely

The system can be tested with potable clean and filtered water or compressed air without oilCompressed air is suitable in particularly low temperatures when there lies the risk of ice formation and in potable water distribution systems if too much time may elapse between the test and actual use with consequent hygienic risks due to the presence of stagnant water inside the pipes

Testing with waterThe test is carried out in two steps ndash leak test and hydraulic test ndash using pressure gauges with 01 bar resolution In case of a difference in tem-perature gt 10 K between the filling water and ambient temperature the test must be carried out at least 30 minutes after fillingAutomatic venting and drainage systems must be closed properly to prevent compromising the test The hydraulic test follows the leak test if the latter is successful

The leak test is carried out by filling the system with water keeping it at a pressure between 1 and 65 bar and visually checking each fitting and joint to detect any leak andor unpressed fitting andor joints that are not implemented correctly Warning The Gerpex fittings do not have the Leak Before Pressed function whereas the Gerpex LBP fittings do This function allows un-pressed fittings to be visually identified through water leaks that occur within a pressure range of 1 and 65 bar and is guaranteed and certified for Gerpex LBP fittings in combination with the Emmeti Gerpex RA and Emmeti Alpert pipes using Emmeti Gerpex equipment)

The hydraulic test for sanitary installations is carried out according to EN 806-4 with a test pressure of 11 bar (11 x MDP) which is to be maintained for at least 30 minutes MDP= Maximum Design Pressure = 10 bar

The hydraulic test for heating systems is carried out according to EN 14336 with a test pressure of 13 x Operating Pressure and in any case between 4 and 6 bar which is to be maintained for at least 120 minutesDetails are found in the two regulations

Testing with airThe test is carried out in two steps ndash leak test and load test ndash using pres-sure gauges with a 1 mbar resolution and an appropriate method of detec-tion (eg soapy water) The load test follows the leak test if the latteris successful

The leak test is carried out by filling the system with compressed air at a pressure between 110 and 150 mbar which is to be maintained for at least 30 minutes for volumes of up to 100 litres In the case of greater volumes the test duration must be increased by 10 minutes for every additional 100 litres

The load test is carried out by filling the system with compressed air at a pressure of 3 bar (up to dimension 50x4) or 1 bar (for dimensions ge 63x45) which is to be maintained for at least 30 minutes in the case of volumes of up to 100 litres In the case of greater volumes the test duration must be increased by 10 minutes for every additional 100 litres

At the end of the test the installer must fill and provide the customer with the relevant report which can be downloaded from the following link

Press fittings Gerpex

FeaturesGerpex Emmeti press-fittings have been designed to be installed in conjunc-tion with electric or manual pressing devicesThis type of joint has become increasingly more popular due to its extremely simple and quick installation along with the high level of temperature and pressure resistanceThe jaw specific for every diameter of fittings compresses a stainless steel sleeve which secures the pipe onto the core of the fitting The hydraulic and mechanical sealing is guaranteed by the special profile of the fitting and the double O-ringAfter pressing the fitting produces a joint with maximum stability and dura-tion which makes it particularly suitable in embedded installations

Construction detailsThe stainless steel sleeve is connected to the fitting along with the blue plas-tic ringEach sleeve has the indication of the diameterThe plastic ring has four important functionsbull impedit prevents electric contact between the layer of aluminium of the

pipe and the brass body of the fitting thus preventing the risk of possible corrosion

bull it allows the installer to check via the sight holes that the pipe has been inserted fully into the fitting

bull it guides the correct positioning of the jaws around the sleevebull fixes the sleeve to the fitting

Compression fittingsFeaturesThe use of compression fittings makes easier the installation of the mul-tilayer system and moreover it requires very few toolsThe 24x19 thread allows the use of a single type of fittings in combination to four seals with different sizes thus rationalising stocksThe hydraulic seal is ensured by means of the system with three O-rings and a pipe-shaped toothed ogiveAll the fittings are equipped with a special PTFE ring that electrically isolates the pipe aluminium layer from the brass fitting

Construction detailsThe single body seal is supplied with it components (nut ogive adaptor)already assembled and ready for insertion into the pipeThe opening on the nut makes it possible to verify if the fitting has beeninserted all the way down to the Seat point

Installing the systemAll installation operations must be carried out at temperatures above -10 degC and below 45 degC to avoid any possible damage to the materialsIn case of temperatures below 0 degC store the materials (pipes and fit-tings) at a higher temperature before use

Surface mounted installationIn surface mounted installations in false ceilings in the gaps of dry wall systems (eg plasterboard) and in shafts the pipes must be adequately secured with suitable collars placed at a distance of no more than a cer-tain value that depends on the size of the pipe

It is preferable to use elbow unions to form curves on pipes with a diam-eter greater than 26 mmWhen bending the pipe you must also avoid putting pressure on the unions already installed and the distance between a union and the be-ginning of the bend must be greater than 5xoslash where Oslash is the external diameter of the pipe

L = 5 x Oslash

Thermal expansionDuring the installation phase pay particular attention to thermal expan-sion that can particularly affect multilayer pipes The elongation a pipe undergoes as a result of a variation in temperature can be calculated with the following formula

ΔL = α x L x ΔT

where

α is the coefficient of linear expansion equal to 0026 mmm K for insulated pipes

L is the initial length of the pipe (m)

ΔT is the temperature difference (K)

ExampleLength of pipe 12 mTemperature difference 50 KΔL = 0026 x 12 x 50 = 156 mm

L = Length (m)ΔT = Temperature difference (K)

ΔL = Longitudinal expansion (mm)

In surface mounted installations or installations in false ceilings and shafts longitudinal thermal expansion can be compensated for through careful arrangement of fixed and sliding brackets (points) depending on the type of installation thus providing suitable thermal expansion compensators

Where pipes are concealed or embedded in screed (laid in the floor) ther-mal expansion can be compensated for by creating an insulated curve at least every 10m (for example with an insulating foam sheath or by pass-ing the pipe through flexible tubing)

Note where the pipes are being used in radiant circuits (spiral or serpen-tine for underfloor heatingcooling) these guidelines do not apply

WhereLs = C x radic (Oslash x ΔL)Ls = Length of compensator (mm)Oslash = External diameter of pipe (mm)C = Material constant (for multilayer metal-plastic pipes C=33)

WithΔL = 156 mm (previous example)Oslash = 26 mmthe result will beLs = 33 x radic (26 x 156) = 665 mm

In order to guarantee the free movement of pipes in an installation inside a vertical shaft with horizontal branches the branches must have a mini-mum free length Ls and the passage through the side wall of the shaft should be free and the pipe protected with a sheath (Fig A and B)

System testingThe test must be carried out once the system is completed with the installation of the pipes and fittings before walling the concealed parts definitely

The system can be tested with potable clean and filtered water or compressed air without oilCompressed air is suitable in particularly low temperatures when there lies the risk of ice formation and in potable water distribution systems if too much time may elapse between the test and actual use with consequent hygienic risks due to the presence of stagnant water inside the pipes

Testing with waterThe test is carried out in two steps ndash leak test and hydraulic test ndash using pressure gauges with 01 bar resolution In case of a difference in tem-perature gt 10 K between the filling water and ambient temperature the test must be carried out at least 30 minutes after fillingAutomatic venting and drainage systems must be closed properly to prevent compromising the test The hydraulic test follows the leak test if the latter is successful

The leak test is carried out by filling the system with water keeping it at a pressure between 1 and 65 bar and visually checking each fitting and joint to detect any leak andor unpressed fitting andor joints that are not implemented correctly Warning The Gerpex fittings do not have the Leak Before Pressed function whereas the Gerpex LBP fittings do This function allows un-pressed fittings to be visually identified through water leaks that occur within a pressure range of 1 and 65 bar and is guaranteed and certified for Gerpex LBP fittings in combination with the Emmeti Gerpex RA and Emmeti Alpert pipes using Emmeti Gerpex equipment)

The hydraulic test for sanitary installations is carried out according to EN 806-4 with a test pressure of 11 bar (11 x MDP) which is to be maintained for at least 30 minutes MDP= Maximum Design Pressure = 10 bar

The hydraulic test for heating systems is carried out according to EN 14336 with a test pressure of 13 x Operating Pressure and in any case between 4 and 6 bar which is to be maintained for at least 120 minutesDetails are found in the two regulations

Testing with airThe test is carried out in two steps ndash leak test and load test ndash using pres-sure gauges with a 1 mbar resolution and an appropriate method of detec-tion (eg soapy water) The load test follows the leak test if the latteris successful

The leak test is carried out by filling the system with compressed air at a pressure between 110 and 150 mbar which is to be maintained for at least 30 minutes for volumes of up to 100 litres In the case of greater volumes the test duration must be increased by 10 minutes for every additional 100 litres

The load test is carried out by filling the system with compressed air at a pressure of 3 bar (up to dimension 50x4) or 1 bar (for dimensions ge 63x45) which is to be maintained for at least 30 minutes in the case of volumes of up to 100 litres In the case of greater volumes the test duration must be increased by 10 minutes for every additional 100 litres

At the end of the test the installer must fill and provide the customer with the relevant report which can be downloaded from the following link

CuttingCut the multilayer pipe with a pipe cutter or shears verifying that the cut is perpendicular to the pipe axis

Calibration - FlaringCalibrate the cut end using the relevant calibrator which calibrates and flares the cut end of the pipe (Fig C)The operation is essential as it determines the correct internal diameter of the pipe and creates the rounded end that eases introduction of the fitting

Insertion the fittingInsert the fitting into the pipe fully home the transparent plastic ring al-lows verification of correct positioning (Fig D) Fig C Fig D

Completion of pressingRemove the pressing device and open the jaws again

Compression fittingsFeaturesThe use of compression fittings makes easier the installation of the mul-tilayer system and moreover it requires very few toolsThe 24x19 thread allows the use of a single type of fittings in combination to four seals with different sizes thus rationalising stocksThe hydraulic seal is ensured by means of the system with three O-rings and a pipe-shaped toothed ogiveAll the fittings are equipped with a special PTFE ring that electrically isolates the pipe aluminium layer from the brass fitting

Construction detailsThe single body seal is supplied with it components (nut ogive adaptor)already assembled and ready for insertion into the pipeThe opening on the nut makes it possible to verify if the fitting has beeninserted all the way down to the Seat point

Installing the systemAll installation operations must be carried out at temperatures above -10 degC and below 45 degC to avoid any possible damage to the materialsIn case of temperatures below 0 degC store the materials (pipes and fit-tings) at a higher temperature before use

Surface mounted installationIn surface mounted installations in false ceilings in the gaps of dry wall systems (eg plasterboard) and in shafts the pipes must be adequately secured with suitable collars placed at a distance of no more than a cer-tain value that depends on the size of the pipe

Surface embedded installationIn surface embedded installations the pipes must be suitably secured with ties and there must be a minimum distance between them of 80 cm on straight lengths and placed 30 cm before and after each bendFor this type of installation it is preferable to lay insulated pipe that has a foam sheath covering or pass the pipe through flexible tubing

Press fittings in laying concealed piping the press fittings must be pro-tected from corrosion that can result from contact with chemicals con-tained in plasters and mortarsIt is possible to use boxing adhesive tapes specifically adapted for such applications or coverings in an expanded plastic material that has been adequately sealed

It is preferable to use elbow unions to form curves on pipes with a diam-eter greater than 26 mmWhen bending the pipe you must also avoid putting pressure on the unions already installed and the distance between a union and the be-ginning of the bend must be greater than 5xoslash where Oslash is the external diameter of the pipe

L = 5 x Oslash

Thermal expansionDuring the installation phase pay particular attention to thermal expan-sion that can particularly affect multilayer pipes The elongation a pipe undergoes as a result of a variation in temperature can be calculated with the following formula

ΔL = α x L x ΔT

where

α is the coefficient of linear expansion equal to 0026 mmm K for insulated pipes

L is the initial length of the pipe (m)

ΔT is the temperature difference (K)

ExampleLength of pipe 12 mTemperature difference 50 KΔL = 0026 x 12 x 50 = 156 mm

L = Length (m)ΔT = Temperature difference (K)

ΔL = Longitudinal expansion (mm)

In surface mounted installations or installations in false ceilings and shafts longitudinal thermal expansion can be compensated for through careful arrangement of fixed and sliding brackets (points) depending on the type of installation thus providing suitable thermal expansion compensators

Where pipes are concealed or embedded in screed (laid in the floor) ther-mal expansion can be compensated for by creating an insulated curve at least every 10m (for example with an insulating foam sheath or by pass-ing the pipe through flexible tubing)

Note where the pipes are being used in radiant circuits (spiral or serpen-tine for underfloor heatingcooling) these guidelines do not apply

WhereLs = C x radic (Oslash x ΔL)Ls = Length of compensator (mm)Oslash = External diameter of pipe (mm)C = Material constant (for multilayer metal-plastic pipes C=33)

WithΔL = 156 mm (previous example)Oslash = 26 mmthe result will beLs = 33 x radic (26 x 156) = 665 mm

In order to guarantee the free movement of pipes in an installation inside a vertical shaft with horizontal branches the branches must have a mini-mum free length Ls and the passage through the side wall of the shaft should be free and the pipe protected with a sheath (Fig A and B)

In case the size of the shaft doesnrsquot allow for a compensator of length Ls the hole in the side wall should be increased in size and at the same time the tube should be protected with an insulating sheath of thickness Sge 15xΔL (Fig C)

System testingThe test must be carried out once the system is completed with the installation of the pipes and fittings before walling the concealed parts definitely

The system can be tested with potable clean and filtered water or compressed air without oilCompressed air is suitable in particularly low temperatures when there lies the risk of ice formation and in potable water distribution systems if too much time may elapse between the test and actual use with consequent hygienic risks due to the presence of stagnant water inside the pipes

Testing with waterThe test is carried out in two steps ndash leak test and hydraulic test ndash using pressure gauges with 01 bar resolution In case of a difference in tem-perature gt 10 K between the filling water and ambient temperature the test must be carried out at least 30 minutes after fillingAutomatic venting and drainage systems must be closed properly to prevent compromising the test The hydraulic test follows the leak test if the latter is successful

The leak test is carried out by filling the system with water keeping it at a pressure between 1 and 65 bar and visually checking each fitting and joint to detect any leak andor unpressed fitting andor joints that are not implemented correctly Warning The Gerpex fittings do not have the Leak Before Pressed function whereas the Gerpex LBP fittings do This function allows un-pressed fittings to be visually identified through water leaks that occur within a pressure range of 1 and 65 bar and is guaranteed and certified for Gerpex LBP fittings in combination with the Emmeti Gerpex RA and Emmeti Alpert pipes using Emmeti Gerpex equipment)

The hydraulic test for sanitary installations is carried out according to EN 806-4 with a test pressure of 11 bar (11 x MDP) which is to be maintained for at least 30 minutes MDP= Maximum Design Pressure = 10 bar

The hydraulic test for heating systems is carried out according to EN 14336 with a test pressure of 13 x Operating Pressure and in any case between 4 and 6 bar which is to be maintained for at least 120 minutesDetails are found in the two regulations

Testing with airThe test is carried out in two steps ndash leak test and load test ndash using pres-sure gauges with a 1 mbar resolution and an appropriate method of detec-tion (eg soapy water) The load test follows the leak test if the latteris successful

The leak test is carried out by filling the system with compressed air at a pressure between 110 and 150 mbar which is to be maintained for at least 30 minutes for volumes of up to 100 litres In the case of greater volumes the test duration must be increased by 10 minutes for every additional 100 litres

The load test is carried out by filling the system with compressed air at a pressure of 3 bar (up to dimension 50x4) or 1 bar (for dimensions ge 63x45) which is to be maintained for at least 30 minutes in the case of volumes of up to 100 litres In the case of greater volumes the test duration must be increased by 10 minutes for every additional 100 litres

At the end of the test the installer must fill and provide the customer with the relevant report which can be downloaded from the following link

Installing the systemAll installation operations must be carried out at temperatures above -10 degC and below 45 degC to avoid any possible damage to the materialsIn case of temperatures below 0 degC store the materials (pipes and fit-tings) at a higher temperature before use

Surface mounted installationIn surface mounted installations in false ceilings in the gaps of dry wall systems (eg plasterboard) and in shafts the pipes must be adequately secured with suitable collars placed at a distance of no more than a cer-tain value that depends on the size of the pipe

Surface embedded installationIn surface embedded installations the pipes must be suitably secured with ties and there must be a minimum distance between them of 80 cm on straight lengths and placed 30 cm before and after each bendFor this type of installation it is preferable to lay insulated pipe that has a foam sheath covering or pass the pipe through flexible tubing

Press fittings in laying concealed piping the press fittings must be pro-tected from corrosion that can result from contact with chemicals con-tained in plasters and mortarsIt is possible to use boxing adhesive tapes specifically adapted for such applications or coverings in an expanded plastic material that has been adequately sealed

It is preferable to use elbow unions to form curves on pipes with a diam-eter greater than 26 mmWhen bending the pipe you must also avoid putting pressure on the unions already installed and the distance between a union and the be-ginning of the bend must be greater than 5xoslash where Oslash is the external diameter of the pipe

L = 5 x Oslash

Thermal expansionDuring the installation phase pay particular attention to thermal expan-sion that can particularly affect multilayer pipes The elongation a pipe undergoes as a result of a variation in temperature can be calculated with the following formula

ΔL = α x L x ΔT

where

α is the coefficient of linear expansion equal to 0026 mmm K for insulated pipes

L is the initial length of the pipe (m)

ΔT is the temperature difference (K)

ExampleLength of pipe 12 mTemperature difference 50 KΔL = 0026 x 12 x 50 = 156 mm

L = Length (m)ΔT = Temperature difference (K)

ΔL = Longitudinal expansion (mm)

In surface mounted installations or installations in false ceilings and shafts longitudinal thermal expansion can be compensated for through careful arrangement of fixed and sliding brackets (points) depending on the type of installation thus providing suitable thermal expansion compensators

Where pipes are concealed or embedded in screed (laid in the floor) ther-mal expansion can be compensated for by creating an insulated curve at least every 10m (for example with an insulating foam sheath or by pass-ing the pipe through flexible tubing)

Note where the pipes are being used in radiant circuits (spiral or serpen-tine for underfloor heatingcooling) these guidelines do not apply

WhereLs = C x radic (Oslash x ΔL)Ls = Length of compensator (mm)Oslash = External diameter of pipe (mm)C = Material constant (for multilayer metal-plastic pipes C=33)

WithΔL = 156 mm (previous example)Oslash = 26 mmthe result will beLs = 33 x radic (26 x 156) = 665 mm

In order to guarantee the free movement of pipes in an installation inside a vertical shaft with horizontal branches the branches must have a mini-mum free length Ls and the passage through the side wall of the shaft should be free and the pipe protected with a sheath (Fig A and B)

In case the size of the shaft doesnrsquot allow for a compensator of length Ls the hole in the side wall should be increased in size and at the same time the tube should be protected with an insulating sheath of thickness Sge 15xΔL (Fig C)

System testingThe test must be carried out once the system is completed with the installation of the pipes and fittings before walling the concealed parts definitely

The system can be tested with potable clean and filtered water or compressed air without oilCompressed air is suitable in particularly low temperatures when there lies the risk of ice formation and in potable water distribution systems if too much time may elapse between the test and actual use with consequent hygienic risks due to the presence of stagnant water inside the pipes

Testing with waterThe test is carried out in two steps ndash leak test and hydraulic test ndash using pressure gauges with 01 bar resolution In case of a difference in tem-perature gt 10 K between the filling water and ambient temperature the test must be carried out at least 30 minutes after fillingAutomatic venting and drainage systems must be closed properly to prevent compromising the test The hydraulic test follows the leak test if the latter is successful

The leak test is carried out by filling the system with water keeping it at a pressure between 1 and 65 bar and visually checking each fitting and joint to detect any leak andor unpressed fitting andor joints that are not implemented correctly Warning The Gerpex fittings do not have the Leak Before Pressed function whereas the Gerpex LBP fittings do This function allows un-pressed fittings to be visually identified through water leaks that occur within a pressure range of 1 and 65 bar and is guaranteed and certified for Gerpex LBP fittings in combination with the Emmeti Gerpex RA and Emmeti Alpert pipes using Emmeti Gerpex equipment)

The hydraulic test for sanitary installations is carried out according to EN 806-4 with a test pressure of 11 bar (11 x MDP) which is to be maintained for at least 30 minutes MDP= Maximum Design Pressure = 10 bar

The hydraulic test for heating systems is carried out according to EN 14336 with a test pressure of 13 x Operating Pressure and in any case between 4 and 6 bar which is to be maintained for at least 120 minutesDetails are found in the two regulations

Testing with airThe test is carried out in two steps ndash leak test and load test ndash using pres-sure gauges with a 1 mbar resolution and an appropriate method of detec-tion (eg soapy water) The load test follows the leak test if the latteris successful

The leak test is carried out by filling the system with compressed air at a pressure between 110 and 150 mbar which is to be maintained for at least 30 minutes for volumes of up to 100 litres In the case of greater volumes the test duration must be increased by 10 minutes for every additional 100 litres

The load test is carried out by filling the system with compressed air at a pressure of 3 bar (up to dimension 50x4) or 1 bar (for dimensions ge 63x45) which is to be maintained for at least 30 minutes in the case of volumes of up to 100 litres In the case of greater volumes the test duration must be increased by 10 minutes for every additional 100 litres

At the end of the test the installer must fill and provide the customer with the relevant report which can be downloaded from the following link

Installing the systemAll installation operations must be carried out at temperatures above -10 degC and below 45 degC to avoid any possible damage to the materialsIn case of temperatures below 0 degC store the materials (pipes and fit-tings) at a higher temperature before use

Surface mounted installationIn surface mounted installations in false ceilings in the gaps of dry wall systems (eg plasterboard) and in shafts the pipes must be adequately secured with suitable collars placed at a distance of no more than a cer-tain value that depends on the size of the pipe

Surface embedded installationIn surface embedded installations the pipes must be suitably secured with ties and there must be a minimum distance between them of 80 cm on straight lengths and placed 30 cm before and after each bendFor this type of installation it is preferable to lay insulated pipe that has a foam sheath covering or pass the pipe through flexible tubing

Press fittings in laying concealed piping the press fittings must be pro-tected from corrosion that can result from contact with chemicals con-tained in plasters and mortarsIt is possible to use boxing adhesive tapes specifically adapted for such applications or coverings in an expanded plastic material that has been adequately sealed

It is preferable to use elbow unions to form curves on pipes with a diam-eter greater than 26 mmWhen bending the pipe you must also avoid putting pressure on the unions already installed and the distance between a union and the be-ginning of the bend must be greater than 5xoslash where Oslash is the external diameter of the pipe

L = 5 x Oslash

Thermal expansionDuring the installation phase pay particular attention to thermal expan-sion that can particularly affect multilayer pipes The elongation a pipe undergoes as a result of a variation in temperature can be calculated with the following formula

ΔL = α x L x ΔT

where

α is the coefficient of linear expansion equal to 0026 mmm K for insulated pipes

L is the initial length of the pipe (m)

ΔT is the temperature difference (K)

ExampleLength of pipe 12 mTemperature difference 50 KΔL = 0026 x 12 x 50 = 156 mm

L = Length (m)ΔT = Temperature difference (K)

ΔL = Longitudinal expansion (mm)

In surface mounted installations or installations in false ceilings and shafts longitudinal thermal expansion can be compensated for through careful arrangement of fixed and sliding brackets (points) depending on the type of installation thus providing suitable thermal expansion compensators

Where pipes are concealed or embedded in screed (laid in the floor) ther-mal expansion can be compensated for by creating an insulated curve at least every 10m (for example with an insulating foam sheath or by pass-ing the pipe through flexible tubing)

Note where the pipes are being used in radiant circuits (spiral or serpen-tine for underfloor heatingcooling) these guidelines do not apply

WhereLs = C x radic (Oslash x ΔL)Ls = Length of compensator (mm)Oslash = External diameter of pipe (mm)C = Material constant (for multilayer metal-plastic pipes C=33)

WithΔL = 156 mm (previous example)Oslash = 26 mmthe result will beLs = 33 x radic (26 x 156) = 665 mm

In order to guarantee the free movement of pipes in an installation inside a vertical shaft with horizontal branches the branches must have a mini-mum free length Ls and the passage through the side wall of the shaft should be free and the pipe protected with a sheath (Fig A and B)

In case the size of the shaft doesnrsquot allow for a compensator of length Ls the hole in the side wall should be increased in size and at the same time the tube should be protected with an insulating sheath of thickness Sge 15xΔL (Fig C)

System testingThe test must be carried out once the system is completed with the installation of the pipes and fittings before walling the concealed parts definitely

The system can be tested with potable clean and filtered water or compressed air without oilCompressed air is suitable in particularly low temperatures when there lies the risk of ice formation and in potable water distribution systems if too much time may elapse between the test and actual use with consequent hygienic risks due to the presence of stagnant water inside the pipes

Testing with waterThe test is carried out in two steps ndash leak test and hydraulic test ndash using pressure gauges with 01 bar resolution In case of a difference in tem-perature gt 10 K between the filling water and ambient temperature the test must be carried out at least 30 minutes after fillingAutomatic venting and drainage systems must be closed properly to prevent compromising the test The hydraulic test follows the leak test if the latter is successful

The leak test is carried out by filling the system with water keeping it at a pressure between 1 and 65 bar and visually checking each fitting and joint to detect any leak andor unpressed fitting andor joints that are not implemented correctly Warning The Gerpex fittings do not have the Leak Before Pressed function whereas the Gerpex LBP fittings do This function allows un-pressed fittings to be visually identified through water leaks that occur within a pressure range of 1 and 65 bar and is guaranteed and certified for Gerpex LBP fittings in combination with the Emmeti Gerpex RA and Emmeti Alpert pipes using Emmeti Gerpex equipment)

The hydraulic test for sanitary installations is carried out according to EN 806-4 with a test pressure of 11 bar (11 x MDP) which is to be maintained for at least 30 minutes MDP= Maximum Design Pressure = 10 bar

The hydraulic test for heating systems is carried out according to EN 14336 with a test pressure of 13 x Operating Pressure and in any case between 4 and 6 bar which is to be maintained for at least 120 minutesDetails are found in the two regulations

Testing with airThe test is carried out in two steps ndash leak test and load test ndash using pres-sure gauges with a 1 mbar resolution and an appropriate method of detec-tion (eg soapy water) The load test follows the leak test if the latteris successful

The leak test is carried out by filling the system with compressed air at a pressure between 110 and 150 mbar which is to be maintained for at least 30 minutes for volumes of up to 100 litres In the case of greater volumes the test duration must be increased by 10 minutes for every additional 100 litres

The load test is carried out by filling the system with compressed air at a pressure of 3 bar (up to dimension 50x4) or 1 bar (for dimensions ge 63x45) which is to be maintained for at least 30 minutes in the case of volumes of up to 100 litres In the case of greater volumes the test duration must be increased by 10 minutes for every additional 100 litres

At the end of the test the installer must fill and provide the customer with the relevant report which can be downloaded from the following link

Installing the systemAll installation operations must be carried out at temperatures above -10 degC and below 45 degC to avoid any possible damage to the materialsIn case of temperatures below 0 degC store the materials (pipes and fit-tings) at a higher temperature before use

Surface mounted installationIn surface mounted installations in false ceilings in the gaps of dry wall systems (eg plasterboard) and in shafts the pipes must be adequately secured with suitable collars placed at a distance of no more than a cer-tain value that depends on the size of the pipe

Surface embedded installationIn surface embedded installations the pipes must be suitably secured with ties and there must be a minimum distance between them of 80 cm on straight lengths and placed 30 cm before and after each bendFor this type of installation it is preferable to lay insulated pipe that has a foam sheath covering or pass the pipe through flexible tubing

Press fittings in laying concealed piping the press fittings must be pro-tected from corrosion that can result from contact with chemicals con-tained in plasters and mortarsIt is possible to use boxing adhesive tapes specifically adapted for such applications or coverings in an expanded plastic material that has been adequately sealed

It is preferable to use elbow unions to form curves on pipes with a diam-eter greater than 26 mmWhen bending the pipe you must also avoid putting pressure on the unions already installed and the distance between a union and the be-ginning of the bend must be greater than 5xoslash where Oslash is the external diameter of the pipe

L = 5 x Oslash

Thermal expansionDuring the installation phase pay particular attention to thermal expan-sion that can particularly affect multilayer pipes The elongation a pipe undergoes as a result of a variation in temperature can be calculated with the following formula

ΔL = α x L x ΔT

where

α is the coefficient of linear expansion equal to 0026 mmm K for insulated pipes

L is the initial length of the pipe (m)

ΔT is the temperature difference (K)

ExampleLength of pipe 12 mTemperature difference 50 KΔL = 0026 x 12 x 50 = 156 mm

L = Length (m)ΔT = Temperature difference (K)

ΔL = Longitudinal expansion (mm)

In surface mounted installations or installations in false ceilings and shafts longitudinal thermal expansion can be compensated for through careful arrangement of fixed and sliding brackets (points) depending on the type of installation thus providing suitable thermal expansion compensators

Where pipes are concealed or embedded in screed (laid in the floor) ther-mal expansion can be compensated for by creating an insulated curve at least every 10m (for example with an insulating foam sheath or by pass-ing the pipe through flexible tubing)

Note where the pipes are being used in radiant circuits (spiral or serpen-tine for underfloor heatingcooling) these guidelines do not apply

WhereLs = C x radic (Oslash x ΔL)Ls = Length of compensator (mm)Oslash = External diameter of pipe (mm)C = Material constant (for multilayer metal-plastic pipes C=33)

WithΔL = 156 mm (previous example)Oslash = 26 mmthe result will beLs = 33 x radic (26 x 156) = 665 mm

In order to guarantee the free movement of pipes in an installation inside a vertical shaft with horizontal branches the branches must have a mini-mum free length Ls and the passage through the side wall of the shaft should be free and the pipe protected with a sheath (Fig A and B)

In case the size of the shaft doesnrsquot allow for a compensator of length Ls the hole in the side wall should be increased in size and at the same time the tube should be protected with an insulating sheath of thickness Sge 15xΔL (Fig C)

System testingThe test must be carried out once the system is completed with the installation of the pipes and fittings before walling the concealed parts definitely

The system can be tested with potable clean and filtered water or compressed air without oilCompressed air is suitable in particularly low temperatures when there lies the risk of ice formation and in potable water distribution systems if too much time may elapse between the test and actual use with consequent hygienic risks due to the presence of stagnant water inside the pipes

Testing with waterThe test is carried out in two steps ndash leak test and hydraulic test ndash using pressure gauges with 01 bar resolution In case of a difference in tem-perature gt 10 K between the filling water and ambient temperature the test must be carried out at least 30 minutes after fillingAutomatic venting and drainage systems must be closed properly to prevent compromising the test The hydraulic test follows the leak test if the latter is successful

The leak test is carried out by filling the system with water keeping it at a pressure between 1 and 65 bar and visually checking each fitting and joint to detect any leak andor unpressed fitting andor joints that are not implemented correctly Warning The Gerpex fittings do not have the Leak Before Pressed function whereas the Gerpex LBP fittings do This function allows un-pressed fittings to be visually identified through water leaks that occur within a pressure range of 1 and 65 bar and is guaranteed and certified for Gerpex LBP fittings in combination with the Emmeti Gerpex RA and Emmeti Alpert pipes using Emmeti Gerpex equipment)

The hydraulic test for sanitary installations is carried out according to EN 806-4 with a test pressure of 11 bar (11 x MDP) which is to be maintained for at least 30 minutes MDP= Maximum Design Pressure = 10 bar

The hydraulic test for heating systems is carried out according to EN 14336 with a test pressure of 13 x Operating Pressure and in any case between 4 and 6 bar which is to be maintained for at least 120 minutesDetails are found in the two regulations

Testing with airThe test is carried out in two steps ndash leak test and load test ndash using pres-sure gauges with a 1 mbar resolution and an appropriate method of detec-tion (eg soapy water) The load test follows the leak test if the latteris successful

The leak test is carried out by filling the system with compressed air at a pressure between 110 and 150 mbar which is to be maintained for at least 30 minutes for volumes of up to 100 litres In the case of greater volumes the test duration must be increased by 10 minutes for every additional 100 litres

The load test is carried out by filling the system with compressed air at a pressure of 3 bar (up to dimension 50x4) or 1 bar (for dimensions ge 63x45) which is to be maintained for at least 30 minutes in the case of volumes of up to 100 litres In the case of greater volumes the test duration must be increased by 10 minutes for every additional 100 litres

At the end of the test the installer must fill and provide the customer with the relevant report which can be downloaded from the following link

Gerpex and Gerpex LBP press fittings system

CuttingCut the multilayer pipe with a pipe cutter or shears verifying that the cut is perpendicular to the pipe axis

Calibration - FlaringCalibrate the cut end using the relevant calibrator which calibrates and flares the cut end of the pipe (Fig C)The operation is essential as it determines the correct internal diameter of the pipe and creates the rounded end that eases introduction of the fitting

Insertion the fittingInsert the fitting into the pipe fully home the transparent plastic ring al-lows verification of correct positioning (Fig D) Fig C Fig D

Completion of pressingRemove the pressing device and open the jaws again

Fig G

PressingPlace the jaws around the sleeve (Fig E) by aligning the collar of the plastic ring with the groove of the jaws (Fig F)Start the hydraulic press-fitting tool until it clicks signalling the comple-tion of the press-fitting operation (Fig G)The operation must be done carefully so that the pipes are kept free of any tension Once the fitting has been pressed avoid placing the joint under any tension

Installing the systemAll installation operations must be carried out at temperatures above -10 degC and below 45 degC to avoid any possible damage to the materialsIn case of temperatures below 0 degC store the materials (pipes and fit-tings) at a higher temperature before use

Surface mounted installationIn surface mounted installations in false ceilings in the gaps of dry wall systems (eg plasterboard) and in shafts the pipes must be adequately secured with suitable collars placed at a distance of no more than a cer-tain value that depends on the size of the pipe

Surface embedded installationIn surface embedded installations the pipes must be suitably secured with ties and there must be a minimum distance between them of 80 cm on straight lengths and placed 30 cm before and after each bendFor this type of installation it is preferable to lay insulated pipe that has a foam sheath covering or pass the pipe through flexible tubing

Press fittings in laying concealed piping the press fittings must be pro-tected from corrosion that can result from contact with chemicals con-tained in plasters and mortarsIt is possible to use boxing adhesive tapes specifically adapted for such applications or coverings in an expanded plastic material that has been adequately sealed

It is preferable to use elbow unions to form curves on pipes with a diam-eter greater than 26 mmWhen bending the pipe you must also avoid putting pressure on the unions already installed and the distance between a union and the be-ginning of the bend must be greater than 5xoslash where Oslash is the external diameter of the pipe

Oslash

Thermal expansionDuring the installation phase pay particular attention to thermal expan-sion that can particularly affect multilayer pipes The elongation a pipe undergoes as a result of a variation in temperature can be calculated with the following formula

ΔL = α x L x ΔT

where

α is the coefficient of linear expansion equal to 0026 mmm K for insulated pipes

L is the initial length of the pipe (m)

ΔT is the temperature difference (K)

ExampleLength of pipe 12 mTemperature difference 50 KΔL = 0026 x 12 x 50 = 156 mm

L = Length (m)ΔT = Temperature difference (K)

ΔL = Longitudinal expansion (mm)

In surface mounted installations or installations in false ceilings and shafts longitudinal thermal expansion can be compensated for through careful arrangement of fixed and sliding brackets (points) depending on the type of installation thus providing suitable thermal expansion compensators

Where pipes are concealed or embedded in screed (laid in the floor) ther-mal expansion can be compensated for by creating an insulated curve at least every 10m (for example with an insulating foam sheath or by pass-ing the pipe through flexible tubing)

Note where the pipes are being used in radiant circuits (spiral or serpen-tine for underfloor heatingcooling) these guidelines do not apply

WhereLs = C x radic (Oslash x ΔL)Ls = Length of compensator (mm)Oslash = External diameter of pipe (mm)C = Material constant (for multilayer metal-plastic pipes C=33)

WithΔL = 156 mm (previous example)Oslash = 26 mmthe result will beLs = 33 x radic (26 x 156) = 665 mm

In order to guarantee the free movement of pipes in an installation inside a vertical shaft with horizontal branches the branches must have a mini-mum free length Ls and the passage through the side wall of the shaft should be free and the pipe protected with a sheath (Fig A and B)

In case the size of the shaft doesnrsquot allow for a compensator of length Ls the hole in the side wall should be increased in size and at the same time the tube should be protected with an insulating sheath of thickness Sge 15xΔL (Fig C)

System testingThe test must be carried out once the system is completed with the installation of the pipes and fittings before walling the concealed parts definitely

The system can be tested with potable clean and filtered water or compressed air without oilCompressed air is suitable in particularly low temperatures when there lies the risk of ice formation and in potable water distribution systems if too much time may elapse between the test and actual use with consequent hygienic risks due to the presence of stagnant water inside the pipes

Testing with waterThe test is carried out in two steps ndash leak test and hydraulic test ndash using pressure gauges with 01 bar resolution In case of a difference in tem-perature gt 10 K between the filling water and ambient temperature the test must be carried out at least 30 minutes after fillingAutomatic venting and drainage systems must be closed properly to prevent compromising the test The hydraulic test follows the leak test if the latter is successful

The leak test is carried out by filling the system with water keeping it at a pressure between 1 and 65 bar and visually checking each fitting and joint to detect any leak andor unpressed fitting andor joints that are not implemented correctly Warning The Gerpex fittings do not have the Leak Before Pressed function whereas the Gerpex LBP fittings do This function allows un-pressed fittings to be visually identified through water leaks that occur within a pressure range of 1 and 65 bar and is guaranteed and certified for Gerpex LBP fittings in combination with the Emmeti Gerpex RA and Emmeti Alpert pipes using Emmeti Gerpex equipment)

The hydraulic test for sanitary installations is carried out according to EN 806-4 with a test pressure of 11 bar (11 x MDP) which is to be maintained for at least 30 minutes MDP= Maximum Design Pressure = 10 bar

The hydraulic test for heating systems is carried out according to EN 14336 with a test pressure of 13 x Operating Pressure and in any case between 4 and 6 bar which is to be maintained for at least 120 minutesDetails are found in the two regulations

Testing with airThe test is carried out in two steps ndash leak test and load test ndash using pres-sure gauges with a 1 mbar resolution and an appropriate method of detec-tion (eg soapy water) The load test follows the leak test if the latteris successful

The leak test is carried out by filling the system with compressed air at a pressure between 110 and 150 mbar which is to be maintained for at least 30 minutes for volumes of up to 100 litres In the case of greater volumes the test duration must be increased by 10 minutes for every additional 100 litres

The load test is carried out by filling the system with compressed air at a pressure of 3 bar (up to dimension 50x4) or 1 bar (for dimensions ge 63x45) which is to be maintained for at least 30 minutes in the case of volumes of up to 100 litres In the case of greater volumes the test duration must be increased by 10 minutes for every additional 100 litres

At the end of the test the installer must fill and provide the customer with the relevant report which can be downloaded from the following link

Surface embedded installationIn surface embedded installations the pipes must be suitably secured with ties and there must be a minimum distance between them of 80 cm on straight lengths and placed 30 cm before and after each bendFor this type of installation it is preferable to lay insulated pipe that has a foam sheath covering or pass the pipe through flexible tubing

Press fittings in laying concealed piping the press fittings must be pro-tected from corrosion that can result from contact with chemicals con-tained in plasters and mortarsIt is possible to use boxing adhesive tapes specifically adapted for such applications or coverings in an expanded plastic material that has been adequately sealed

It is preferable to use elbow unions to form curves on pipes with a diam-eter greater than 26 mmWhen bending the pipe you must also avoid putting pressure on the unions already installed and the distance between a union and the be-ginning of the bend must be greater than 5xoslash where Oslash is the external diameter of the pipe

L = 5 x Oslash

Thermal expansionDuring the installation phase pay particular attention to thermal expan-sion that can particularly affect multilayer pipes The elongation a pipe undergoes as a result of a variation in temperature can be calculated with the following formula

ΔL = α x L x ΔT

where

α is the coefficient of linear expansion equal to 0026 mmm K for insulated pipes

L is the initial length of the pipe (m)

ΔT is the temperature difference (K)

ExampleLength of pipe 12 mTemperature difference 50 KΔL = 0026 x 12 x 50 = 156 mm

L = Length (m)ΔT = Temperature difference (K)

ΔL = Longitudinal expansion (mm)

In surface mounted installations or installations in false ceilings and shafts longitudinal thermal expansion can be compensated for through careful arrangement of fixed and sliding brackets (points) depending on the type of installation thus providing suitable thermal expansion compensators

Where pipes are concealed or embedded in screed (laid in the floor) ther-mal expansion can be compensated for by creating an insulated curve at least every 10m (for example with an insulating foam sheath or by pass-ing the pipe through flexible tubing)

Note where the pipes are being used in radiant circuits (spiral or serpen-tine for underfloor heatingcooling) these guidelines do not apply

WhereLs = C x radic (Oslash x ΔL)Ls = Length of compensator (mm)Oslash = External diameter of pipe (mm)C = Material constant (for multilayer metal-plastic pipes C=33)

WithΔL = 156 mm (previous example)Oslash = 26 mmthe result will beLs = 33 x radic (26 x 156) = 665 mm

In order to guarantee the free movement of pipes in an installation inside a vertical shaft with horizontal branches the branches must have a mini-mum free length Ls and the passage through the side wall of the shaft should be free and the pipe protected with a sheath (Fig A and B)

In case the size of the shaft doesnrsquot allow for a compensator of length Ls the hole in the side wall should be increased in size and at the same time the tube should be protected with an insulating sheath of thickness Sge 15xΔL (Fig C)

System testingThe test must be carried out once the system is completed with the installation of the pipes and fittings before walling the concealed parts definitely

The system can be tested with potable clean and filtered water or compressed air without oilCompressed air is suitable in particularly low temperatures when there lies the risk of ice formation and in potable water distribution systems if too much time may elapse between the test and actual use with consequent hygienic risks due to the presence of stagnant water inside the pipes

Testing with waterThe test is carried out in two steps ndash leak test and hydraulic test ndash using pressure gauges with 01 bar resolution In case of a difference in tem-perature gt 10 K between the filling water and ambient temperature the test must be carried out at least 30 minutes after fillingAutomatic venting and drainage systems must be closed properly to prevent compromising the test The hydraulic test follows the leak test if the latter is successful

The leak test is carried out by filling the system with water keeping it at a pressure between 1 and 65 bar and visually checking each fitting and joint to detect any leak andor unpressed fitting andor joints that are not implemented correctly Warning The Gerpex fittings do not have the Leak Before Pressed function whereas the Gerpex LBP fittings do This function allows un-pressed fittings to be visually identified through water leaks that occur within a pressure range of 1 and 65 bar and is guaranteed and certified for Gerpex LBP fittings in combination with the Emmeti Gerpex RA and Emmeti Alpert pipes using Emmeti Gerpex equipment)

The hydraulic test for sanitary installations is carried out according to EN 806-4 with a test pressure of 11 bar (11 x MDP) which is to be maintained for at least 30 minutes MDP= Maximum Design Pressure = 10 bar

The hydraulic test for heating systems is carried out according to EN 14336 with a test pressure of 13 x Operating Pressure and in any case between 4 and 6 bar which is to be maintained for at least 120 minutesDetails are found in the two regulations

Testing with airThe test is carried out in two steps ndash leak test and load test ndash using pres-sure gauges with a 1 mbar resolution and an appropriate method of detec-tion (eg soapy water) The load test follows the leak test if the latteris successful

The leak test is carried out by filling the system with compressed air at a pressure between 110 and 150 mbar which is to be maintained for at least 30 minutes for volumes of up to 100 litres In the case of greater volumes the test duration must be increased by 10 minutes for every additional 100 litres

The load test is carried out by filling the system with compressed air at a pressure of 3 bar (up to dimension 50x4) or 1 bar (for dimensions ge 63x45) which is to be maintained for at least 30 minutes in the case of volumes of up to 100 litres In the case of greater volumes the test duration must be increased by 10 minutes for every additional 100 litres

At the end of the test the installer must fill and provide the customer with the relevant report which can be downloaded from the following link

Installing the systemAll installation operations must be carried out at temperatures above -10 degC and below 45 degC to avoid any possible damage to the materialsIn case of temperatures below 0 degC store the materials (pipes and fit-tings) at a higher temperature before use

Surface mounted installationIn surface mounted installations in false ceilings in the gaps of dry wall systems (eg plasterboard) and in shafts the pipes must be adequately secured with suitable collars placed at a distance of no more than a cer-tain value that depends on the size of the pipe

Surface embedded installationIn surface embedded installations the pipes must be suitably secured with ties and there must be a minimum distance between them of 80 cm on straight lengths and placed 30 cm before and after each bendFor this type of installation it is preferable to lay insulated pipe that has a foam sheath covering or pass the pipe through flexible tubing

Press fittings in laying concealed piping the press fittings must be pro-tected from corrosion that can result from contact with chemicals con-tained in plasters and mortarsIt is possible to use boxing adhesive tapes specifically adapted for such applications or coverings in an expanded plastic material that has been adequately sealed

It is preferable to use elbow unions to form curves on pipes with a diam-eter greater than 26 mmWhen bending the pipe you must also avoid putting pressure on the unions already installed and the distance between a union and the be-ginning of the bend must be greater than 5xoslash where Oslash is the external diameter of the pipe

L = 5 x Oslash

Thermal expansionDuring the installation phase pay particular attention to thermal expan-sion that can particularly affect multilayer pipes The elongation a pipe undergoes as a result of a variation in temperature can be calculated with the following formula

ΔL = α x L x ΔT

where

α is the coefficient of linear expansion equal to 0026 mmm K for insulated pipes

L is the initial length of the pipe (m)

ΔT is the temperature difference (K)

ExampleLength of pipe 12 mTemperature difference 50 KΔL = 0026 x 12 x 50 = 156 mm

L = Length (m)ΔT = Temperature difference (K)

ΔL = Longitudinal expansion (mm)

In surface mounted installations or installations in false ceilings and shafts longitudinal thermal expansion can be compensated for through careful arrangement of fixed and sliding brackets (points) depending on the type of installation thus providing suitable thermal expansion compensators

Where pipes are concealed or embedded in screed (laid in the floor) ther-mal expansion can be compensated for by creating an insulated curve at least every 10m (for example with an insulating foam sheath or by pass-ing the pipe through flexible tubing)

Note where the pipes are being used in radiant circuits (spiral or serpen-tine for underfloor heatingcooling) these guidelines do not apply

WhereLs = C x radic (Oslash x ΔL)Ls = Length of compensator (mm)Oslash = External diameter of pipe (mm)C = Material constant (for multilayer metal-plastic pipes C=33)

WithΔL = 156 mm (previous example)Oslash = 26 mmthe result will beLs = 33 x radic (26 x 156) = 665 mm

In order to guarantee the free movement of pipes in an installation inside a vertical shaft with horizontal branches the branches must have a mini-mum free length Ls and the passage through the side wall of the shaft should be free and the pipe protected with a sheath (Fig A and B)

Fig A Fig B Fig C

In case the size of the shaft doesnrsquot allow for a compensator of length Ls the hole in the side wall should be increased in size and at the same time the tube should be protected with an insulating sheath of thickness Sge 15xΔL (Fig C)

System testingThe test must be carried out once the system is completed with the installation of the pipes and fittings before walling the concealed parts definitely

The system can be tested with potable clean and filtered water or compressed air without oilCompressed air is suitable in particularly low temperatures when there lies the risk of ice formation and in potable water distribution systems if too much time may elapse between the test and actual use with consequent hygienic risks due to the presence of stagnant water inside the pipes

Testing with waterThe test is carried out in two steps ndash leak test and hydraulic test ndash using pressure gauges with 01 bar resolution In case of a difference in tem-perature gt 10 K between the filling water and ambient temperature the test must be carried out at least 30 minutes after fillingAutomatic venting and drainage systems must be closed properly to prevent compromising the test The hydraulic test follows the leak test if the latter is successful

The leak test is carried out by filling the system with water keeping it at a pressure between 1 and 65 bar and visually checking each fitting and joint to detect any leak andor unpressed fitting andor joints that are not implemented correctly Warning The Gerpex fittings do not have the Leak Before Pressed function whereas the Gerpex LBP fittings do This function allows un-pressed fittings to be visually identified through water leaks that occur within a pressure range of 1 and 65 bar and is guaranteed and certified for Gerpex LBP fittings in combination with the Emmeti Gerpex RA and Emmeti Alpert pipes using Emmeti Gerpex equipment)

The hydraulic test for sanitary installations is carried out according to EN 806-4 with a test pressure of 11 bar (11 x MDP) which is to be maintained for at least 30 minutes MDP= Maximum Design Pressure = 10 bar

The hydraulic test for heating systems is carried out according to EN 14336 with a test pressure of 13 x Operating Pressure and in any case between 4 and 6 bar which is to be maintained for at least 120 minutesDetails are found in the two regulations

Testing with airThe test is carried out in two steps ndash leak test and load test ndash using pres-sure gauges with a 1 mbar resolution and an appropriate method of detec-tion (eg soapy water) The load test follows the leak test if the latteris successful

The leak test is carried out by filling the system with compressed air at a pressure between 110 and 150 mbar which is to be maintained for at least 30 minutes for volumes of up to 100 litres In the case of greater volumes the test duration must be increased by 10 minutes for every additional 100 litres

The load test is carried out by filling the system with compressed air at a pressure of 3 bar (up to dimension 50x4) or 1 bar (for dimensions ge 63x45) which is to be maintained for at least 30 minutes in the case of volumes of up to 100 litres In the case of greater volumes the test duration must be increased by 10 minutes for every additional 100 litres

At the end of the test the installer must fill and provide the customer with the relevant report which can be downloaded from the following link

It is preferable to use elbow unions to form curves on pipes with a diam-eter greater than 26 mmWhen bending the pipe you must also avoid putting pressure on the unions already installed and the distance between a union and the be-ginning of the bend must be greater than 5xoslash where Oslash is the external diameter of the pipe

L = 5 x Oslash

Oslash

Thermal expansionDuring the installation phase pay particular attention to thermal expan-sion that can particularly affect multilayer pipes The elongation a pipe undergoes as a result of a variation in temperature can be calculated with the following formula

ΔL = α x L x ΔT

where

α is the coefficient of linear expansion equal to 0026 mmm K for insulated pipes

L is the initial length of the pipe (m)

ΔT is the temperature difference (K)

ExampleLength of pipe 12 mTemperature difference 50 KΔL = 0026 x 12 x 50 = 156 mm

L = Length (m)ΔT = Temperature difference (K)

ΔL = Longitudinal expansion (mm)

In surface mounted installations or installations in false ceilings and shafts longitudinal thermal expansion can be compensated for through careful arrangement of fixed and sliding brackets (points) depending on the type of installation thus providing suitable thermal expansion compensators

Where pipes are concealed or embedded in screed (laid in the floor) ther-mal expansion can be compensated for by creating an insulated curve at least every 10m (for example with an insulating foam sheath or by pass-ing the pipe through flexible tubing)

Note where the pipes are being used in radiant circuits (spiral or serpen-tine for underfloor heatingcooling) these guidelines do not apply

WhereLs = C x radic (Oslash x ΔL)Ls = Length of compensator (mm)Oslash = External diameter of pipe (mm)C = Material constant (for multilayer metal-plastic pipes C=33)

WithΔL = 156 mm (previous example)Oslash = 26 mmthe result will beLs = 33 x radic (26 x 156) = 665 mm

In order to guarantee the free movement of pipes in an installation inside a vertical shaft with horizontal branches the branches must have a mini-mum free length Ls and the passage through the side wall of the shaft should be free and the pipe protected with a sheath (Fig A and B)

Fig A Fig B Fig C

In case the size of the shaft doesnrsquot allow for a compensator of length Ls the hole in the side wall should be increased in size and at the same time the tube should be protected with an insulating sheath of thickness Sge 15xΔL (Fig C)

System testingThe test must be carried out once the system is completed with the installation of the pipes and fittings before walling the concealed parts definitely

The system can be tested with potable clean and filtered water or compressed air without oilCompressed air is suitable in particularly low temperatures when there lies the risk of ice formation and in potable water distribution systems if too much time may elapse between the test and actual use with consequent hygienic risks due to the presence of stagnant water inside the pipes

Testing with waterThe test is carried out in two steps ndash leak test and hydraulic test ndash using pressure gauges with 01 bar resolution In case of a difference in tem-perature gt 10 K between the filling water and ambient temperature the test must be carried out at least 30 minutes after fillingAutomatic venting and drainage systems must be closed properly to prevent compromising the test The hydraulic test follows the leak test if the latter is successful

The leak test is carried out by filling the system with water keeping it at a pressure between 1 and 65 bar and visually checking each fitting and joint to detect any leak andor unpressed fitting andor joints that are not implemented correctly Warning The Gerpex fittings do not have the Leak Before Pressed function whereas the Gerpex LBP fittings do This function allows un-pressed fittings to be visually identified through water leaks that occur within a pressure range of 1 and 65 bar and is guaranteed and certified for Gerpex LBP fittings in combination with the Emmeti Gerpex RA and Emmeti Alpert pipes using Emmeti Gerpex equipment)

The hydraulic test for sanitary installations is carried out according to EN 806-4 with a test pressure of 11 bar (11 x MDP) which is to be maintained for at least 30 minutes MDP= Maximum Design Pressure = 10 bar

The hydraulic test for heating systems is carried out according to EN 14336 with a test pressure of 13 x Operating Pressure and in any case between 4 and 6 bar which is to be maintained for at least 120 minutesDetails are found in the two regulations

Testing with airThe test is carried out in two steps ndash leak test and load test ndash using pres-sure gauges with a 1 mbar resolution and an appropriate method of detec-tion (eg soapy water) The load test follows the leak test if the latteris successful

The leak test is carried out by filling the system with compressed air at a pressure between 110 and 150 mbar which is to be maintained for at least 30 minutes for volumes of up to 100 litres In the case of greater volumes the test duration must be increased by 10 minutes for every additional 100 litres

The load test is carried out by filling the system with compressed air at a pressure of 3 bar (up to dimension 50x4) or 1 bar (for dimensions ge 63x45) which is to be maintained for at least 30 minutes in the case of volumes of up to 100 litres In the case of greater volumes the test duration must be increased by 10 minutes for every additional 100 litres

At the end of the test the installer must fill and provide the customer with the relevant report which can be downloaded from the following link

Where pipes are concealed or embedded in screed (laid in the floor) ther-mal expansion can be compensated for by creating an insulated curve at least every 10m (for example with an insulating foam sheath or by pass-ing the pipe through flexible tubing)

Note where the pipes are being used in radiant circuits (spiral or serpen-tine for underfloor heatingcooling) these guidelines do not apply

WhereLs = C x radic (Oslash x ΔL)Ls = Length of compensator (mm)Oslash = External diameter of pipe (mm)C = Material constant (for multilayer metal-plastic pipes C=33)

WithΔL = 156 mm (previous example)Oslash = 26 mmthe result will beLs = 33 x radic (26 x 156) = 665 mm

In order to guarantee the free movement of pipes in an installation inside a vertical shaft with horizontal branches the branches must have a mini-mum free length Ls and the passage through the side wall of the shaft should be free and the pipe protected with a sheath (Fig A and B)

In case the size of the shaft doesnrsquot allow for a compensator of length Ls the hole in the side wall should be increased in size and at the same time the tube should be protected with an insulating sheath of thickness Sge 15xΔL (Fig C)

System testingThe test must be carried out once the system is completed with the installation of the pipes and fittings before walling the concealed parts definitely

The system can be tested with potable clean and filtered water or compressed air without oilCompressed air is suitable in particularly low temperatures when there lies the risk of ice formation and in potable water distribution systems if too much time may elapse between the test and actual use with consequent hygienic risks due to the presence of stagnant water inside the pipes

Testing with waterThe test is carried out in two steps ndash leak test and hydraulic test ndash using pressure gauges with 01 bar resolution In case of a difference in tem-perature gt 10 K between the filling water and ambient temperature the test must be carried out at least 30 minutes after fillingAutomatic venting and drainage systems must be closed properly to prevent compromising the test The hydraulic test follows the leak test if the latter is successful

The leak test is carried out by filling the system with water keeping it at a pressure between 1 and 65 bar and visually checking each fitting and joint to detect any leak andor unpressed fitting andor joints that are not implemented correctly Warning The Gerpex fittings do not have the Leak Before Pressed function whereas the Gerpex LBP fittings do This function allows un-pressed fittings to be visually identified through water leaks that occur within a pressure range of 1 and 65 bar and is guaranteed and certified for Gerpex LBP fittings in combination with the Emmeti Gerpex RA and Emmeti Alpert pipes using Emmeti Gerpex equipment)

The hydraulic test for sanitary installations is carried out according to EN 806-4 with a test pressure of 11 bar (11 x MDP) which is to be maintained for at least 30 minutes MDP= Maximum Design Pressure = 10 bar

The hydraulic test for heating systems is carried out according to EN 14336 with a test pressure of 13 x Operating Pressure and in any case between 4 and 6 bar which is to be maintained for at least 120 minutesDetails are found in the two regulations

Testing with airThe test is carried out in two steps ndash leak test and load test ndash using pres-sure gauges with a 1 mbar resolution and an appropriate method of detec-tion (eg soapy water) The load test follows the leak test if the latteris successful

The leak test is carried out by filling the system with compressed air at a pressure between 110 and 150 mbar which is to be maintained for at least 30 minutes for volumes of up to 100 litres In the case of greater volumes the test duration must be increased by 10 minutes for every additional 100 litres

The load test is carried out by filling the system with compressed air at a pressure of 3 bar (up to dimension 50x4) or 1 bar (for dimensions ge 63x45) which is to be maintained for at least 30 minutes in the case of volumes of up to 100 litres In the case of greater volumes the test duration must be increased by 10 minutes for every additional 100 litres

At the end of the test the installer must fill and provide the customer with the relevant report which can be downloaded from the following link

Testing with airThe test is carried out in two steps ndash leak test and load test ndash using pres-sure gauges with a 1 mbar resolution and an appropriate method of detec-tion (eg soapy water) The load test follows the leak test if the latteris successful

The leak test is carried out by filling the system with compressed air at a pressure between 110 and 150 mbar which is to be maintained for at least 30 minutes for volumes of up to 100 litres In the case of greater volumes the test duration must be increased by 10 minutes for every additional 100 litres

The load test is carried out by filling the system with compressed air at a pressure of 3 bar (up to dimension 50x4) or 1 bar (for dimensions ge 63x45) which is to be maintained for at least 30 minutes in the case of volumes of up to 100 litres In the case of greater volumes the test duration must be increased by 10 minutes for every additional 100 litres

At the end of the test the installer must fill and provide the customer with the relevant report which can be downloaded from the following link

CuttingCut the multilayer pipe with a pipe cutter or shears verifying that the cut is perpendicular to the pipe axis

Calibration - FlaringCalibrate the cut end using the relevant calibrator which calibrates and flares the cut end of the pipe (Fig C)The operation is essential as it determines the correct internal diameter of the pipe and creates the rounded end that eases introduction of the fitting

Insertion the fittingInsert the fitting into the pipe fully home the transparent plastic ring al-lows verification of correct positioning (Fig D) Fig C Fig D

Completion of pressingRemove the pressing device and open the jaws again
