Resistance Tests Against Aggressive Environments

It is necessary to test the corrosion resistance and functionality of materials that are intended to be exposed to high pressure, high temperatures or a corrosive environment. In advanced laboratories, the life of metallic components is tested in harsh and aggressive environments with accelerated corrosion test applications. Often times, customized tests are also implemented to suit businesses' requirements.

To determine the corrosion resistance of products, tests are carried out at atmospheric pressure where it is possible to add toxic and corrosive gases such as hydrogen sulfide. Autoclaves are operated at temperatures up to 350 degrees and pressures up to 350 bar, and at the same time, the product or materials are exposed to hazardous chemicals at speeds up to 1000 revolutions per minute. In this way, the actual operating conditions of the component in an operational context are simulated after installation. After the final test, mechanical properties are also tested to determine whether the material can withstand the intended environment in practice.

In addition to performing customized tests on autoclaves to industry standards, full-scale chamber failure analysis or verification testing is also possible. Large components and systems can be tested. Full-scale tests reveal the cause of the failure and thus help take action to prevent a recurrence.

If a business operates in environments where very high or low temperatures or pressures are effective, or involves working with hazardous materials, special environmental testing gives confidence in the components. The performance of materials and joints in aggressive environments is tested to determine the effect of conditions on a part's mechanical properties or defect tolerance.

The main resistance tests against aggressive environments carried out within this framework include:

• Fatigue crack growth, tensile and fracture tests in environments with pressures up to 50 bar at temperatures between minus 80 degrees and plus 1000 degrees
• Test for exposure to temperatures up to 1400 degrees at pressures up to 300 bar
• Corrosion test in oxygen and chlorine up to 80 degrees
• Permeability test at temperatures up to 250 degrees and pressures up to 650 bar
