Chemical seal guide

In the world of pressure measurement, the CHEMICAL SEAL has a predominant place. All severe, dangerous or hygienic processes require a CHEMICAL SEAL to be fi tted between the process and the measuring instrument.

Nowhere is this more true than in the petrochemical, pharma-ceutical and food processing industries.

This guide, covering the majority of cases, will assist you in choosing the right CHEMICAL SEAL for the safe and correct measurement of your process.

What is a chemical seal?

Industrial pressure measurement covers a very wide range of gases or liquids (fl uids). The physical or chemical properties of these products sometimes make them incompatible for contact with the sensing elements of pressure gauges or transmitters.In such cases the measuring instrument (pressure gauge or transmitter) must be separated from the pressurised fl uid by a system capable of transmitting the pressure to this instrument while isolating it from the fl uid itself.

This system is known as a chemical seal

It consists basically of a fl exible diaphragm, clamped or welded between two rigid housings.

When is a chemical seal used?

A chemical seal is used for pressure measurement in thefollowing applications:

1- Viscous or turbid process fl uids:These fl uids could obstruct the measuring instrument (Bourdon tube or sensor).

2- Fluids that solidify at ambient temperature:These fl uids could solidify in the measuring instrument.

3- Corrosive fl uids:These could corrode the measuring instrument causing it to break.

4- Toxic fl uids:In this case, the chemical seal forms an additional barrier between the fl uid and the atmosphere.

5- Food and pharmaceutical liquids:The main problem in food-processing or pharmaceuticalprocesses is to eliminate as much dead volume as possible. These volumes are inaccessible for cleaning and provide a site in which bacteria can develop. A Bourdon tube or sensor connection are examples of dead volumes.The solution is to fi t either fl ush-diaphragm chemical seals with a food grade connection or in-line chemical seals that assistcleaning and sterilisation in place (CIP, SIP*).

* CIP, or "cleaning in place", is a phase of the process consisting of a cyclic fl ushing of the facility with solvents which clean all the components and pipes without dismantling. SIP, or “sterilisation in place”, consists of a sterilising the complete facility by steam injection.

General

Which chemical seal?

1- Viscous or turbid fl uids:Use a chemical seal mounted on a fl ange withsuitably sized inlet port (DN) or fl ush-diaphragmchemical seal.

2- Fluids that solidify at ambient temperature:It is preferable to use a fl anged or fl ush-diaphragm chemical seal. The chemical seal can be installed inside the heat insulation system so that the fl uid itself is kept at the process temperature. It can also be ins-talled outside the heat insulation system and kept at process temperature by a heating system (e.g. steam circulation).

3- Corrosive fl uids:The corrosive power of a fl uid depends on its nature, pressure, temperature and concentration. The material of the chemical seal parts wetted by the process fl uid (bottom housing and diaphragm) must be compatible.Sometimes coatings need to be used.

4- Toxic fl uids:The dimensions of diaphragms used by Bourdon-Haenni have been determined by extensive testing. Their lowdeformation strain rate guarantees long service life.In the unlikely event of a tube burst, the diaphragm is pushed against the body of the chemical seal, blocking any product leakage.After an incident of this kind, the chemical seal must bereplaced.

5- Food and pharmaceutical fl uids:For food and pharmaceutical fl uids, Bourdon-Haenni has developed a very full range of fl ush-diaphragm chemical seals based on all the pressure connections used in these types of industry.Special attention is given to the surface condition of diaphragms and welds to ensure that they comply with FDA recommendations (see “Regulations and Standards” chapter) and prevailing standards.The surface roughness of diaphragms is usually Ra 0.8 (µm) maximum and as an option, Ra 0.4 (µm) maximum.

The standard connections are fi tted to pipes by welded tees which invariably contain a dead volume.To remedy this problem, Bourdon-Haenni has developed a range of in-line chemical seals which eliminate this dead volume.This type of chemical seal is especially suited to sensitive pharmaceutical processes and biotechnology industries.

Compatibility with the measuring instrument: The fi rst step in choosing your chemical seal is to check that it is compatible with your pressure measuring instrument (pressure gauge or transmitter).Each family of measuring instruments has a compatibility table. Use this table to check the compatibility of your device with the chosen chemical seal.

Information - Measuringinstrument fi tted on chemical seal

The volume of transmission liquid that the diaphragm can move is limited by its mechanical characteristics.

For a pressure gauge, the volume of the Bourdon tube increases as greater pressure is applied (this is also the case for pressure sensors, but there is less volume variation).

The movement of the chemical seal diaphragm must compensate for the volume variation of the Bourdon tube and the expansion variation of the transmission fl uid.

The suitability of a chemical seal for a measuring instrument must therefore be calculated according to:- The pressure to be measured- The volume absorbed by the measuring instrument- The dead volume of the measuring instrument- The length of the pipe between the chemical seal and the measuring instrument- The extreme ambient and fl uid temperatures.

The result of these calculations is given by the compatibility tables. There are compatibility tables for all Bourdon-Haenni product ranges: pressure gauges, pressure switches, pressure transmit-ters.

These tables concern the most common applications.Please contact us for any other conditions.

Compatibility with a«Process» chemical seal

To meet the needs of the chemical and petrochemical industries Bourdon-Haenni has developed the D900 chemical seal range.These chemical seals for corrosive or viscous fl uids provide enhanced performance, especially at high temperatures.

These chemical seals can be fi tted on the following Bourdon-Haenni products: EDD575, Flexbar.

Our know-how and experience enable us to equip «process» pressure transmitters for other manufacturers such as ABB, EPM, Foxboro, Honeywell, etc.Please contact us for details with your requirements.

Difference in elevation

If the chemical seal is not installed at the same height as the pressure measuring instrument (with the two devices separated by a connecting capillary), the pressure indicated by the instrument must be corrected by the pressure value corresponding to the height of the liquid column in the capillary.

1- Measuring instrument installed below the chemical seal: A negative correction must be made.2- Measuring instrument installed above the chemical seal: A positive correction must be made.

Note:Due to the vacuum created by the column height, a measu-ring instrument must never be installed more than 6 metres above the chemical seal (limited to 4 metres for the LRS4).

Application notes

Measurement error

Measurement error introduced by a chemical seal

Our chemical seals are designed not to introduce measurement error. The stiff ness (Km) of the diaphragms used is a low as possible compared to the stiff ness of the measuring instrument. Stiff ness is characterised by the ratio Km:

Km= ∆V ∆PWhere: ∆V: Displaced volume in cm3

∆P: Pressure diff erence in mbar.

Generally, fi tting a chemical seal introduces no additional error at 20°C on the measuring instrument to which it is fi tted.

Chemical seals designed to operate with oxygen undergo a special cleaning procedure. The transmission fl uid used is a fl uorocarbon (LRS4 - Max. P. 1-0 bar at 60°C) which does not react in contact with oxygen. This guarantees the safety of the device if there is an accidental diaphragm failure.

Chemical seals designed for use with chlorinated products are also fi lled with LRS4 transmission fl uid, which is also non-reactive in contact with chlorine.

Instruments used on paint lines (especially in the automotive industry) must be totally free of silicone-based products and any fatty products.LRS7 fi lling liquid is used for this application.

It is possible to fi t a pressure limiter between the chemical seal and the measuring instrument in the following cases:

AORPB : with families D300, D435, D631 (min. pressure 1.6 bar) and D820 (DN80) ambient temperature range -10 ...+80°C

AORP : with families D200, D421, D621 (min. pressure 4 bar) and D820 (DN ≥ 50) ambient temperature range -10 ...+80°C

with families D100, D411, D611 (min. pressure 10 bar) and D820 (DN ≥ 40) ambient temperature range -10 ...+80°C

Please contact us for other cases

It is FORBIDDEN to fi t a damping connection or valve between the chemical seal and the measuring instrument.

Capillary length

The use of capillaries with a chemical seal results in changes to the pressure transmission characteristics and requires certainprecautions.

Response time

Defi nition: With the chemical seal subjected to constant pressure P, the response time is defi ned as the time t, in seconds, required for the pressure measuring instrument mounted on the chemical seal to indicate pressure P’.

The response time of the assembly depends on: - the length and diameter of the capillary,- the transmission fl uid used,- the temperature,- the pressure,- the displaced volume.

Precautions during use

The capillary must be installed in a manner that prevents it from vibrating. There must be no tight bends on the capillary.

To keep the eff ects of temperature as low as possible in diff erential pressure measuring systems, the two capillaries must be mounted in a way that ensures they are infl uenced in an identical manner by the ambient temperature.

RegulationsStandards

Standards for the food, pharmaceutical and biotechnologyindustries

Special requirements: food processing, pharmaceutical and biotechnology processes are subject tospecial hygienic design rules recommended by the FDA.

The general mission of the American Food and Drug Administration is to protect public health in the USA through the following actions:

1. Clinical research, scheduling and monitoring the marketing of human and veterinary drugs, cosmetics and food products.

2. Checking that these products are correctly marked, eff ective and safe.

3. Participating throughout the world in the harmonisation of regulations concerning these products.

Paragraphs 1, 2 and 3 are enforced under the aegis of the General Secretary of the FDA after consulting experts in science, medicine and public health and in co-operation with associations representingconsumers, manufacturers, importers, packagers and distributors of these products.

The FDA’s activities include publishing the "GMP" or "Good Manufacturing Process" rules whichrepresent sound engineering practice in the construction of food processing and pharmaceuticalprocesses.The FDA does not issue certifi cates for items used in the construction of these processes but does conduct regular audits and inspections of these factories*.The instruments manufactured by Bourdon-Haenni for these applications must therefore comply with the rules published by the FDA.

* Factories located anywhere in the world manufacturing products intended for the American market.

"3A sanitary" is the best-known rule in the USA in relation to the hygiene of food processing facility design, especially for dairy and egg products.Parts in contact with the product are manufactured from FDA-approved materials. "3A sanitary" alsoincludes the GMPs, representing sound engineering practice in the construction of food processes,especially concerning the maximum surface roughness (Ra).3A issues certifi cates and permission to use the 3A symbol after auditing the design and the company’s Quality Assurance system.

RegulationsStandards

Enforcement of directives

◊ Pressure Equipment Directive 97/23/CE • Our standard equipment of volume ≤ 1 litre and pressure ≤ 200 bar, or DN ≤ 25 all pressure ratings, or components of pres-sure equipment, is designed and manufactured in compliance with Article 3.3 of 97/23/CE = Sound engineering practice.

• For pressure gauges and transmitters of V ≤ 0.1 litre and P > 200 bar, Category I : compliance with the essen-tial safety requirements of the directive (design, mechanical strength, materials, welded assemblies, safety coeffi -cient, etc.): CE marking.

• For equipment of V > 0.1 litre and P > 200 bar or for use with unstable gas, Category III : compliance with the essen-tial safety requirements, evaluation by notifi ed organisation: CE 0062 (No. of the Bureau Véritas) E.g.: D904 PN250

◊ Explosive Atmosphere Directive ATEX 94/9/CE

• Electrical measuring instruments used in an explosive atmosphere must bear the type certifi cate number of the notifi ed organisation issuing it and the specifi c marking for protection against explosions

E.g.: LCIE 03 ATEX 6125X CE0081 (No. of the Notifi ed Organisation) II 2 G / D followed by the protection mode: EEx dIIC T6 / T5

• For mechanical measuring instruments there are 2 categories: - Category of equipment with moving parts warranting evaluation of the ignition risk (EN13 463-1). Example: Pressure gauges (with no plastic component of surface area > 20 cm2 ) Marking CE II 2 G/D - IM2

- Category of equipment that does not have its own potential source of ignition. Example: Metallic chemical seals, connections, siphons, accessories. These have no specifi c ATEX marking.

Information concerning corrosion resistance

The choice of material for the diaphragm and bottom housing is determined primarily by the corrosiveness of the fl uid to be measured.Corrosion also depends on the surface conditions of parts in contact with the fl uid to be measured, the presence of air (and therefore oxygen) dissolved in the fl uid or corrosion catalysts or inhibitors.The table below provides general compatibility indications. Given the complexity of corrosion phenomena, it is essential to have thesuitability of the chosen material validated (infl uence of temperature, concentration, pressure, shape of the parts, etc.).These choices are the user’s responsibility.
