API vs ASME

[MSPVIN]

after running the sizing calculations for a pressure relief valve, do you use API or ASME orifice area?

Might give it a go here.

The problem with sloppy work is that the supply FAR EXCEEDS the demand

I have never dealt with API as a former N.B. Boiler and Pressure vessel inspector, so if the PV (fired or unfired) is designed per ASME codes, naturally I would base my pressure safety valve and relief valves pressure setting and relieving capacity per ASME. If API codes were used in the fabrication of vessels than I suspect that the calculations would be based on API but from my standpoint I would definitely check with API to determine if I am correct.
