B31.3 or API520 for PSV piping
B31.3 or API520 for PSV piping
(OP)
Hi All, I would really appreciate any help on this matter. I am sizing PSV piping system for a NG processing facility.
According to B31.3,322.6.2 "Pressure Relief Discharge Piping from pressure relieving safety devices shall be designed to facilitate drainage". Does this mean that a bleed valve must be installed on discharge line?
As there is no such requirement by API 520, which standard I should use first?
