Standard Quality Control & Testing
Our Quality Control verifies all processes from material receipt to final customer inspection including liaison with approved Third Party inspection and certifying authorities where required. All products are supplied with certified test reports, which include chemicalphysical analysis and hydrostatic pressure tests. NDT and other specified tests are included in the final certification, if requested. Standard testing is carried out in full compliance with the API , BS, AS, DIN standards applicable to the manufacturing specifications. GA drawings, hydrostatic shell & leakage tests plus mechanical and chemical analysis certificates supplied in accordance with EN10204.3.1.
All valves are high pressure hydrostatic tested on body, seat and low pressure air tested on seat to relevant shut off class. Testing is performed to API 598 or API 6D or other applicable standard such as MSS. Furthermore all valves are visually inspected to MSS-SP55.
Special product testing includes high pressure gas testing, low temperature cryogenic testing, body and stem helium leakage testing, endurance testing, bending testing and high temperature testing. Other specifically dedicated procedures are available and can be performed on request according to our customers’ specifications.
