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.
