To test valves in his fabricated steam pipeline to the standards of ASME B31.3 2006; 345.2.2. The customer is ignoring the testing standards of API-598, ASME B16.34, MSSP-61 and API-6D. While each of these referenced standards states a required minimum testing time, my customer wants to test his pipeline for 2 hours at the testing requirements of WOG x 1.5. While we beleive our testing times of 2-4 min meets the requirements of all applicable testing standards, our customer states he is testing the fabricators work (welding). It is our contention that the customer is putting additional stress to the safety valves in his piping system. Where does the customer's desire stand compared to the adherance of the manufacture to the mandated testing of the above mentioned standards.
If they wanted to do something that wasn't safe, I wouldn't do so. Testing a valve for 2 hours isn't going to hurt the product as long as it was designed/manufactured/inspected, etc. correctly.
When we test equipment outside of our standards, we state this on the COC, which is signed by our customer.
