Valve test bench setup, quick coupling
Valve test bench setup, quick coupling
(OP)
Hello,
tryng to set up a test bench that is easy to use, is there a commercially available coupler that I can use on 2"npt thread (internal and external) for my hydro shell test at 7500psi and a gas closure test at 80-100psi? We are introducing a low cost ball valve, have very tight margins, but of course need to follow the testing laid out in b16.34 and api598. trying to reduce labour costs by having an easy "drop and clamp" in place for testing that would not invalidate the tests.
thanks in advance

RE: Valve test bench setup, quick coupling
I can understand where you are coming from with the 750 psig test requirement Thread make up is going to be a bear if you are using NPT threads in a make and break situation.
Are you talking about large quantities of valves testing each one?
What is the MOC of the valve?
Could you comeback with your exact procedure would be?

do you have a brand name or website for the clamping devices you wrote about?

Here is one of many suppliers of equipment for testing valves.
