Destructive Testing (DT)As the name suggests, destructive testing (DT) includes methods where your material is broken down in order to determine mechanical properties, such as strength, toughness and hardness. In practice it means, for example, finding out if the quality of a weld is good enough to withstand extreme pressure or to verify the properties of a material.

These properties can’t be examined with non-destructive methods, as specimens of the material must be extracted. Destructive testing is generally most suitable and economic for mass produced objects, as the cost of destroying a small number of pieces is negligible. The samples are put under different loads and stress. That way we can analyze in which point your material eventually gives up and cracks. The results gained are then compared to regulations and/or quality guidelines.

Destructive tests are best when used together with our non-destructive methods: this combination gives the best information on materials and welds. Non-destructive tests show if cracks, corrosion or other faults exist. Destructive tests in turn indicate how and when the objects are in danger of breaking down or failing.

Inspecta’s destructive testing services include mechanical testing (tensile, bend and impact tests), hardness testing, macro and micro testing as well as material analysis and metallographic examinations. Inspecta has its’ own, accredited destructive

testing laboratories in several countries. We are also able to execute your required tests at our own workshops. This way we can ensure you get the best service and the most suitable testing methods.

Benefits of Destructive Testing (DT)

 :Non-Destructive TestingNon-destructive testing is used as part of a manufacturing or installation inspection to check if quality demands are being met. As an example, welded steel joints are x-rayed to check the quality of the welding. The radiographic test reveals if the joint is fully welded or contains unacceptable faults.

Non-destructive testing is also used as part of in-service inspections or preventive maintenance to quantify the status of critical components and equipment. As an example, the steel plate floor of a storage tank can be inspected with a special floor scanner. The floor may be subject to corrosion and the scanner measures the

remaining plate thickness. If too thin, the plate needs to be replaced to avoid the tank starting to leak.

 :Calibration of Measurement DevicesMeasurements of mass, length and volume are widely used as reference standards in various industries. For example, in all manufacturing processes, correct measurements are a must in order to comply with the quality assurance criteria set by your company’s quality systems or your customers’ requirements. Measurements can have safety aspects, too. For example, power plants are often dependent on flow measurements, which ensure that the cooling water is flowing in as planned.

Accuracy is, of course, the most important factor regarding measurements. Therefore it is important to calibrate and monitor your measurement devices on a regular basis. Inspecta has the knowhow and the equipment for measuring and calibrating mass, volume, length, electricity, flow, pressure, heat and thermal energy.

In the calibration process, we compare the display readings of the meter with the traceable national and international measurement standards. If they comply, a calibration certificate is given. We can calibrate the instrumentation both in the laboratory and on site at each customer's premises.

Benefits of Calibration of Measurement Devices

Ensures correct measurements on mass, volume, length, electricity, flow, pressure, heat and thermal energy

Saves you money by reducing waste due to accurate measurements Enables smooth production processes

 :Testing of BoilersBoiler reliability, safety and usability are crucial for power plants. Boilers and components in hot conditions, such as wall tubes, cylinders, valves and channels have a limited lifespan; therefore preventive condition monitoring is very important. For you to take the right action at the right time and to optimize the use of boilers means preventing leaks, accidents and interruptions − for the sake of safety, the environment and maximal uptime. Inspecta helps customers to identify and detect potential failures early and to target replacement activities to the right places.

The biggest challenge for boilers is them wearing out, developing, for example, cracks and corrosion. Also the way the boiler is operated has an effect on its life expectancy. In all cases, it is important to find the defects early. Advanced and reliable non-destructive testing (NDT) methods are an essential part of our solution. Inspecta is the leader in applying new technologies to benefit our customers. For example, our latest applications can be used during your normal operations, which enables us to find damage mechanisms and produce valuable information immediately without stopping your business activities.

With our help you can plan ahead, prevent the defects from reoccurring, have inspections when it is suitable for you and use the boiler safely for the next usage period. Inspecta has extensive experience and knowledge in boiler facilities. With careful planning and project management we can target upgrades precisely and carry out projects both time and cost efficiently. Most importantly, in close co-operation with our customers, we can make preventive, risk-based inspection and maintenance plans for the coming years.

Inspecta also supports you in quality assurance during construction or modernisation phases. For example, welding surveillance and weld testing coupled with a profound project and method planning are critical: both to stay on schedule and to be able to resume the process as soon as possible. We also do damage research on welded constructions, test connection strength and toughness properties and determine failure mechanisms. Welding method qualification tests can be done in our own DT laboratory.

Benefits of Testing of Boilers

Minimizes stoppages and downtime by reacting to defects proactively Recognizes problems before they cause damage Prevents leaks and accidents Saves you money Ensures rolling process Protects the environment Promotes safety in the workplace

 :Testing of Heat ExchangersHeat exchangers are vital components in numerous processing plants. Usually they are of bimetallic construction and work with various chemicals at high temperatures. In these conditions corrosion, cracking, erosion, thinning and other damage can occur during operation. With an increasing focus on safety, the environment and operating costs, the benefits achieved from inspections and condition monitoring are self-evident.

Inspecta’s various services help you to maximize performance and take the right action at the right time. Examination and condition monitoring of heat exchangers are performed using a variety of techniques. Selection of the best technique for you depends on your objectives: whether it is fabrication control, preventive in-service inspection, or inspection due to a failure such as a leakage. 

An essential part of our solution is testing services with non-destructive (NDT) methods. For example, unnecessary process downtime, change-out costs and pressure testing can be avoided with these services. Inspecta offers you methods such as IRIS and eddy current testing, which provide high-speed results in finding defects that threaten the safe usage of your heat exchanger tubing.

Home Our Services Testing Testing of Pipelines

 :Testing of PipelinesPipelines have a simple purpose; to transport goods. However, keeping pipelines in good condition throughout the years is not that simple.

In the worst case, defects like corrosion or erosion lead to leakages or explosions. Such problems can, in turn, cause expensive stoppages and serious harm to the environment and people. Therefore early detection of any damage, preventive maintenance and condition monitoring are essential. Inspecta can help you ensure the safety of your pipeline systems.

Detecting defects is usually most cost-efficient when done with advanced non-destructive testing (NDT) techniques when the pipeline is in operation. In such cases your pipeline doesn’t have to be emptied. For example, long range ultrasonic testing (LRUT) can be applied to pipes above and below ground and it can scan up to 150 meters of pipe at one go. LRUT maps anomalies or spots that need to be inspected more closely with other methods such as Digital Radiography.

The combination of suitable NDT methods, careful planning and project management provides the foundation for you to make the right decisions at the right time. We can provide both a broad range of information for risk management, but also deliver detailed information for assessing defects and prioritizing maintenance actions. Inspecta is also constantly developing new applications for in-service monitoring. A major part of our product development is done involving our customers.

Inspecta’s services help you to plan ahead, carry out improvements cost-efficiently, minimize delays in the process and use the pipelines safely. Most advantages can be gained in close co-operation with our inspectors, technical consultants and you, the customer.

 :Testing of Process VesselsProcess vessels are one of the key players in keeping your operation online; malfunctions in them can cause expensive unplanned stoppages. High pressurized process vessels are also highly safety-critical, which makes preventive maintenance and condition monitoring especially important.

In the worst possible case a violent eruption of the pressurized contents could be a huge risk both for your people and the environment. Inspecta has the tools and the knowledge to detect wear, cracks and corrosion reliably in all your process vessel components.

All process vessels have a limited lifespan, and the biggest challenge to them is wear and tear due to heat, chemicals, pressure and the way the vessel is operated. In all cases it is important to find defects early. Our non-destructive testing (NDT) services gather valuable information about the condition of the vessel. This information serves as a basis for you in making the right maintenance or modernization decisions at the right time.

Some of our NDT inspections can be carried out during in-service, which allows process continuity while inspections are made. Inspecta is the Nordic leader in applying new methods and technologies, and we are also constantly developing new applications for in-service monitoring. A major part of our service is product development, which is done in close co-operation with our customers.

The biggest advantages can be reached by creating preventive and risk-based maintenance plans for the future − here inspection information is one of the keys to optimized assets and taking the right action that suit your facilities and processes. With Inspecta’s help, you can plan ahead, make upgrade decisions and work cost efficiently while using the process vessel safely for the next usage period after which a new assessment can be made. We can also provide quality assurance during construction or modernization phases according to related standards.

Benefits of Testing of Process Vessels

Minimizes your stoppages and downtime, increases profitability Recognized problems before they lead to leaks or accidents Protects the environment Ensures rolling process Promotes safety

 :Testing of Storage TanksStorage tanks and their components face several challenges in your process environment: Contents of the tank, weather or operating conditions can lead to leakages that harm both people and the environment. Blocked vents and drains, defective stairways, breached bunt walls and such can turn into safety risks. Possible deterioration causes problems. To keep the container intact and to take the right maintenance action at the right time requires in-depth expertise and accurate information from regular inspections. Here Inspecta can help you.

Inspecta’s service package provides you with a broad range of information about the condition of your tank. During an inspection the tank and its ancillaries is examined to detect any signs of deterioration or defects such as wear and tear, cracks and corrosion. This can be done simply, cost-efficiently, illustratively and reliably with our advanced non-destructive testing (NDT) services. 

We can, for example, map the tank floor with the LFET Floorscan method, which produces a visual map of the condition of the floor plates. For corrosion mapping of the shell plates we can use an ultrasonic crawler. Connecting pipes can be easily scanned with long range ultrasonic testing method. Inspections can be done in-service or out-of-service, depending on what needs to be done.

Inspecta uses the latest methods and techniques for your benefit so that you can plan ahead, have inspections when it is suitable for you, target the maintenance action required and use the facility safely for the next usage period. In addition to the currently used latest techniques, we are constantly doing product development with input from our customers. According to each customers’ needs, we also plan the best ways and times to do the inspections and modernisation − to minimize delays in your process and other functions.

Inspecta’s area of expertise covers also a wide range of other services for tanks. We can, e.g. determine the volume of the tank with a 3D laser measurement system. Most advantages can be gained in close co-operation with our inspectors, technical consultants and you, the customer. Together we make calculations concerning the operating condition of the tank and produce preventive and risk-based maintenance and inspection plans for the future.

Benefits of Testing of Storage Tanks

Assesses the condition of the whole tank from top to floor with all ancillaries Prevents leakages and accidents Protects the environments Enhances safety Maximizes your process uptime and profitability Helps you to take right maintenance action at the right time Advanced testing methods enable in-service inspections; minimize the need of

building scaffolds etc.

 :Testing of GeneratorsUnscheduled plant stoppages, whether caused by technical or human factors, result in loss of profitability. Generators and components that have reached end-of life status cannot continue safe and reliable operation − preventive maintenance actions and well-thought out asset management are keys to productive uptime and safety for people and the environment.

Inspecta offers a wide variety of services that help to manage and optimize the lifecycle of your rotating machinery. Generator objects like shafts, retaining rings or casings; all can have different damage and ‘wear and tear’ to mechanisms which need to be taken into account. Large rotating machinery is also subjected to many kinds of vibration resulting from mechanical, electric or hydraulic problems. When the origin of the vibration is detected it is important to eliminate it.

In all cases it is important for you to assess each machine’s health and identify emerging problems before damage or accidents occur. Here Inspecta’s NDT (non-destructive testing) and condition monitoring services are needed. Defects can be reliably detected with our advanced NDT methods, such as advanced ultrasonic or eddy current sampling. Most condition monitoring challenges can be beaten when NDT inspections and vibration monitoring are combined into a permanent, cost-effective solution. Inspecta is constantly developing new applications for in-service monitoring in order to support our customers’ decision-making with the most accurate information on damaged mechanisms.

Together with our customers we can plan the best ways to carry out inspections and modernization cost-efficiently. With accurate information from inspections, careful planning and project management we help to target maintenance action at the right time. Most advantages can be gained in close co-operation with our inspectors, technical consultants and you, the customer. Together we can, for example, design and build preventive and risk-based maintenance and inspection plans for the future.

Benefits of Testing of Generators

Increases availability and reliability Increases profitability by less unplanned downtime and minimal interruptions Enhances safety Gives you accurate information for maintenance plans and actions Evaluates the condition of your generator and its components, identifies most

critical parts Helps you to manage assets more efficiently Prevents accidents that can harm people and the environment

 

 :Testing of TurbinesUnscheduled plant stoppages always result in loss of profitability, whether caused by technical problems or human factors. All types of turbines play a critical part in

the process, and therefore it is important to keep them running and in good condition as long as possible. Also safety is a major concern that can be improved by finding defects in time, before they cause you problems.

Inspecta’s services help you to face these challenges as we help to find, classify and size flaws. Our long experience of testing gas and steam turbines helps to ensure high usability. For example, creep cracking, corrosion and thermal fatigue threaten the turbine rotors and blade root fixings, which can eventually lead to loss of blades, balance holes and changes of section, brittle fractures or other substantial consequential damage to the turbine.

Non-destructive testing (NDT) is an answer to extend the lifetime of a turbine, as the information we collect serves as a basis for making the right maintenance or modernization decisions at the right time. NDT of a turbine or its components is typically specified for three different purposes: within the different phases of manufacturing or repairs, for quality control of new or re-conditioned components, or for in-service assessment on the run, repair or replace decisions. The majority of the inspections apply visual and surface techniques, but we also use advanced methods to indicate the flaw depths and assess the condition of all part in the turbine.

Inspecta uses the latest methods and techniques for your benefit. We help you to plan ahead, have inspections when it is suitable for you, make upgrades cost-efficiently and use turbines safely for the next usage period, after which a new assessment can be made. Inspecta’s area of expertise also covers a wide range of other services for turbines, such as vibration measurements, constant and online monitoring with remote diagnostics as well as surveillance of tension. We also act as a third party in situations where impartiality is needed together with high quality expertise − e.g. assessing damages to turbines or how well the improvement work succeeded.

Benefits of Testing of Turbines

More profitability through minimized unscheduled plant stoppages High usability and maximum process uptime Enhances proactive maintenance that is targeted correctly Helps you to make the right repair and replacement decisions Well-planned and cost-effective stoppages Ensures safety of the turbines Reliable condition assessments for all parts in the turbine, even the inner parts

 :Non Destructive Testing of Glass-Fibre Reinforced LaminatesAs plastic materials are frequently used for the storage and processing of corrosive liquids, such as strong acids, the consequence of a failure can be devastating.

Non Destructive Testing (NDT) is a requested tool in inspecting tanks and pipes made of glass-fibre reinforced material. Up until now, NDT-methods for field use have not been fully developed for adequate precision.  

Inspecta has developed procedures for several testing methods of Glass Fibre reinforced laminates:

Radiographic testing Ultrasonic testing Visual testing

The NDT inspection of welds and joints is also a major concern for ensuring quality and safety of newly commissioned plants before taking over the ownership from a site contractor.

NDT is a required part of the inspection.

Benefits of NDT of Glass-Fibre Reinforced Laminates

 :Effective replica testing and creep life assessment by use of stress analysis

Components in high temperature piping systems with increased stress levels often experience increased sensitivity for creep (i.e. time dependent deformation) and creep damage development. Finally creep damage results in creep crack formation and failure.

To help you keep track of the creep damage development, replica testing is usually used. In areas of stress concentrations replica testing can be carried out where small spots of the microstructure are examined to assess the amount of creep.

The results from a well prepared stress analysis of your high temperature piping systems, loaded by thermal expansion, dead weight and internal pressure may be used to pinpoint the critical positions for replica testing. Inspecta offers you a complete service so you can be sure your systems are checked and monitored, thus avoiding stoppages and expensive repairs.

Our present service involves significantly improved feasibility for pipe system stress analyses:

Guidelines for efficient pipe modelling:Efficient analyses can now be carried out without any substantial influence on the results. In addition, pitfalls that may appear in compiling input data, programme settings and modelling have been investigated. Our results have been compiled in a guideline for elastic analyses.

Elastic pipe analyses: For steam systems operating just below the limit temperature for creep design, creep cracking is evidently common after 25 years in operation. Replica test positioning can be pinpointed by elastic pipe analysis for such steam pipe systems.

Pipe analysis with creep effects included in the material model:For steam systems operating above or below the limit temperature for creep design, creep relaxation and creep deformation must be considered when performing pipe system stress analyses. It is necessary to consider possible strain accumulation due to starts and stops in your operations as well as being able to pinpoint the critical pipe positions for replica testing.

Component analysis to pinpoint local areas for replica test:We are now also able to model and analyse the true stress and strain distribution over time in components such as T-joints in your steam pipe system. In this way, replica testing can be reduced to the critical positions at component level.

Assessing the remaining creep life:This can be assessed explicitly by analysing creep strain development at critical positions in critical components in service. The results can be verified by replica testing. This concept enables qualified lifetime predictions with far better accuracy than previously. 

Benefits

Inspecta’s replica testing will be more attractive to you by reducing the test positions to those which really are critical. The pipe stress analysis pinpoints which components in a pipeline system should be replica tested.

Such efficiency is crucial in testing pipe systems within any process industry because stoppages are much shorter. 

Your safety levels will be higher since the risk of leaving critical positions untested will be reduced to a minimum.

The possibility of reducing potentially significant pipe system stresses at an early stage is another benefit from the system stress analysis.

Critical positions at component level are determined by the component stress analysis that also considers system stresses form the system analysis.

Increased possibilities for residual lifetime assessments with respect to creep. Residual life assessments of steam pipe line components and systems can be analysed with an accuracy that previously was almost impossible to achieve.

Thickness measurement of tanks and cisterns using LizzardThe Lizzard ultrasound scanner is used for measuring the thickness of walls in tanks and cisterns.

The scanner is fitted with a special detector that continuously measures the speed of sound of the material. The measured speed of sound at any point is used at the same time as the calibration for thickness measurement at that same point. This

eliminates any measurement uncertainty there may be in castings due to the varying speed of sound in the material.

Inspecta’s Lizzard scanner can also be fitted with a video camera for visual inspection.

Benefits of thickness measurement using Lizzard

No scaffolding is needed Provides access to confined spaces Handles materials with varying speed of sound such as castings through automatic

calibration. Provides continuous thickness measurement from end to end of the roller. Inspecta stores all data for analysis, evaluation and supplies you with a detailed

inspection report.

Home Our Services Testing LRUT (Long Range Ultrasonic Testing)

 :LRUT (Long Range Ultrasonic Testing)Long range ultrasonic testing is a rapid way of screening for corrosion in pipelines. The method enables screening of up to 100 meters of pipeline in one test, i.e. 50 meters in both directions.

By fitting a ring of transducers around the pipeline, a wave maker device directs low frequency (20-100 kHz) ultrasonic waves via the transducers, longitudinally into the pipeline wall. The method effectively detects changes in the pipeline’s cross-section, enabling it to indentify corrosion and other abnormalities. At the same time this provides the possibility of using welds and flanges as distance references.

Inspecta has qualified experts in using this method to help you get a cost-effective report on the condition of your pipelines.

The test results are displayed in an easy-to-interpret visual interface on a laptop computer – enabling us to draw conclusions quickly and correctly. Upon identifying a defect we carry out follow-up detailed testing of the affected area, using complementary ultrasonic or x-ray methods.

With this highly advanced testing method you will get an accurate status report of your pipelines in the most effective way.

Benefits of  long range ultrasonic testing

More than 100 times faster than traditional ultrasonic methods Up to 100 meters screening distance on pipelines above ground Up to 10 meters screening distance on pipelines buried in the ground Possibility to do sub-sea scanning Saves time since there is no need to remove insulation, apart from 1 meter for the

transducer ring. Easy to screen wall penetrating pipelines (both built-in and sleeved penetrations)

 :DDA - Digital X-ray with Digital Detector ArrayInspecta has taken the development of digital radiography one step further. Using Digital Detector Array it is now possible to digitally x-ray your equipment during your normal everyday operations.

We perform digital radiography with a digital panel that sends the X-ray image to a computer where the test engineer is able to immediately evaluate the results. Our test engineer assesses the X-ray film and measures the various defects using special software. We reinforce and highlight different parts of the x-rayed equipment to examine any possible defects in more detail.

Inspecta uses different radiation sources depending on the material being tested. A traditional X-ray tube is adequate for most materials. We use a battery-powered pulse X-ray tube for thinner goods with low density, such as plastic. For very thick materials, or materials with a high density, we use isotopes. The digital panel requires less radiation than traditional X-ray film.

Using digital X-rays with Digital Detector Array - DDA it is possible to X-ray through insulation and during your operations. You no longer need to shut down your plant to find out the condition and status of your equipment.

Benefits of digital radiography with Digital Detector Array - DDA

Testing during your daily operations Testing through insulation Testing of various materials such as plastics and composites, wood, aluminium,

steel and concrete Testing of components of varying thickness and material Time saving and cost effective More environmentally friendly than traditional X-ray film 

Phased Array UTInspecta uses Phased Array UT, which is an advanced ultrasonic testing technique that can be used to test everything from butt welds to complex geometries.

The Phased Array UT technique ensures reliable and fast results. By combining different scanning angles in a single scan, the method saves you time and is extremely cost-effective, while it also increases the likelihood of detecting any defects in equipment or facilities. The method highlights the exact location and size of any defects using graphic colour images.

Phased Array UT provides both fast and accurate results for checking everything from your small boiler tubes to your massive turbines and vessels.

A Phased Array probe acts as a probe that has been split into several small elements. Each of these elements sends and receives signals. Our inspectors can control the direction and focus of the sound impulses by varying the time of the pulse elements.

All detection and sizing, which is usually carried out today using conventional UT techniques, can also be performed with Phased Array UT.

Benefits of Phased Array UT 

Provides faster and more efficient testing. Data from the test is saved and archived and can subsequently be evaluated and

compared with previous tests. Graphic colour images can be included in the report. Easier to test complex geometries. Better resolution and characterisation of indications. Can be automated.

 :SLOFEC™Saturation Low Frequency Eddy Current

Corrosion attacks result in high costs to industry each year. The consequences of corrosion can be significant production losses, risk of environmental pollution, and risks to your staff’s safety and health. It is therefore important that corrosion attacks are detected at an early stage.

SLOFEC is a reliable method of detecting corrosion and provides an early warning to help you avoid costly incidents and plant stoppages.

Inspecta’s SLOFEC technology meets today's high demands in the power, heating, oil, gas and petrochemical industries. SLOFEC uses the eddy current principle in combination with a magnetic field. Using induced magnetism, which increases the depth of penetration, defects and all kinds of material losses can be detected deep inside the material. The technique is an inspection method for identifying internal and external corrosion and defects in thin and thick sheet metal and pipes.

The technique can be used for scanning pipes and floors and is extremely effective when testing objects such as pipelines, tank roofs, tank floors, tank walls, spheres, and cisterns. The majority of materials and dimensions can be tested using SLOFEC.

Benefits of scanning with SLOFEC 

Full non-destructive inspections Reliable inspection results High inspection rate Testing through coatings, such as paint layers, with a thickness of up to 10 mm High detection sensitivity of defects in thicknesses up to 35 mm A clear separation of internal and external defects Inspection at higher temperatures Provides clear colour-based mapping of the extent of damage in user-friendly

reports.

 :TSCANInspecta offers you TSCAN, which is a complete system for continuous thickness scanning of magnetic materials. It is specially designed for boiler tubes.

TSCAN can also be used on other types of tubes and even flat surfaces with a nominal thickness of under 12 mm. The results of a TSCAN inspection are presented with an easy to understand overview, C-scan, with colors and thickness values. If all four walls of a boiler are scanned it is possible to create a rotatable 3D image of the boiler.

The high repeatability makes the system perfect for recurrent scanning with the possibility of comparing measurements over time and getting a corrosion rate

estimate. Inspecta’s specialists use TSCAN whenever our clients need to really know the condition of their facility’s systems. You can be assured that our results are clear, easy to understand and very accurate.

Benefits of using TSCAN 

Eliminates the risk of local thinning between manual UT measure points. Low demand on surface conditions; no grinding is necessary. All data is stored and saved for future inspections and measurement comparison. Easy to understand documentation software with changeable settings to get a

personal view. Scanning prior to a planned tube change to get the right extent of tubes to change

can save you a lot of money, since the extent of tubes requiring changing is often exaggerated due to measurement uncertainty from a manual measurement.
