Burst Test Failure Criteria for Control Valves
Burst Test Failure Criteria for Control Valves
(OP)
Hopefully the collective wisdom here can advise me on this topic.
While the hydrostatic proof test of control valves is well defined (e.g. ANSI/ISA-75.19) I have not been able to find a corresponding standard for burst testing.
My research shows an "industry standard" of minimum 4-7 times the MAWP. Is this accurate? And what are the failure criteria? Can we expect, for example, a 1" NPT threaded joint to withstand 2500 psig, and if not does a leaking thread constitute a burst failure for the valve?
Sorry for the rush of questions, but I prefer to follow clear standards where available.
