Valve pressure testing
Thread Content
Differences and operation procedures between valve pressure testing, strength testing, sealing testing, and upper sealing testing. I only know that normal pressure testing is a strength test conducted at 1.5 times the design pressure, with the valve fully open during the test; sealing testing is carried out at 1.1 times the design pressure, with the valve fully closed during the test. What about upper sealing testing?
Shell test at 1.5 times the nominal pressure; sealing test at the nominal pressure
