PSV CDTP calculation based on operating temperature or relieving temperature
(OP)
Dears
I need your advice pls
As per API RP 520,(page 48) the temperature correction factor (multiplier) is typically required when the relieving temperature exceeds 250°F. However in Dresser PSVs(Consolidated PSVs)they are referring the operating temperature not relieving temperature. In Crosby PSVs, they are referring relieving temperature.
Which one will follow?
