Steam - fire case allowable overpressure
Steam - fire case allowable overpressure
(OP)
I am not looking at a fired heater or fired boiler, just a steam containing vessel application in a process unit. What percentage overpressure is allowable for a steam vessel for a fire case?
I have peaked around in API RP 520, API STD 521 and some of the ASME standards. Which standard reflects the allowable overpressure value for steam if different than hydrocarbon?

i've found local codes often are guidelines it depends on my local engineers view !! so that can change,.
sorry dont know the actual answer though

Anyway: Is you steam case a wet fire case (only water in the vessel - set point below the critical pressure of water) then follow API520 section for steam. If the SP is above critical use same, but for superheated steam.
