At offshore, the repaired valves were tested with N2He at 165 Psig but the valves were found to be passing.
Because of that, I have a queried the 8ea Valves 2”x300#RF as regards to what test pressure[I mean using water as the medium] did you test the valves which you did not reply..
• Seat test pressure? , using water as medium,
• Shell test pressure?, using water as medium,
Sent back the valves, but now you tested with a low pressure using N2 at 165 psig. What if they leak again?
You should have tested using water same as you normally do for a 2” x 300#RF.
Please clarify,
