Pressure Testing Services
All deep-sea applications require high quality and pressure-resistant components. Although computer-based calculations and a sophisticated simulation algorithm is available today and certainly help to shorten the development process for such parts, only a test can really prove that the design is according to specification, the right material has been chosen and that no signs of fatigue over the planned operation period will occur.
Therefore, pressure tests are often mandatory as part of the certification process to be accomplished by a notified body.
Pressure testing also allows for monitoring and analyzing the dynamic behavior of individual parts or complex assemblies. As a result, existing designs can be improved before deployment or optimized after detecting issues in the field at a fraction of the cost associated with equivalent offshore trials.
Logging of pressure and temperature
While hydrostatic testing is generally classified as a non-destructive testing method, destructive testing may be necessary in certain cases to gain deeper insights into the performance behavior of test specimens, material properties, and the maximum applicable load before failure. As the test object is either completely or significantly damaged during such procedures, the anticipated fracture behavior is a critical factor in the planning and safe execution of these tests.
Primary designed to conduct tests on large volume glass enclosures made of brittle materials which usually collapse suddenly and generate shockwaves with large impact to the test facility, our pressure chamber can also absorb the forces caused by the different levels of failure during a destructive test of test items made of ductile materials.
FAQs
This method of testing is generally known as non-destructive testing and it is very rare that the product is destroyed, but it can happen.
Hydrostatic testing is used to prove that a product is fit for purpose and that it can retain its working pressure without any leaks. Therefore the worst case is generally that we will see a leak path, rather than the product being completely destroyed.
Hydrostatic testing is mostly used to test that a prototype or new design tweak is functional and leak free. It is also common for this testing to be carried out on a production batch sample test or if the standard dictates every production unit. Testing can be carried out on existing components in the field and this is dictated by the maintenance schedule of an application normally by the end user.
