National Board of Boiler and Pressure Vessel Inspectors - Temperature Considerations for Pressure Relief Valve Application

A valve is required to open at 500 psig inservice where the service temperature is 400° F, and back pressure = 25 psig. Differential set pressure = 500 psig – 25 psig = 475 psig. Temperature multiplier: 1.013. Cold differential test pressure = 475 psig x 1.013 = 481 psig. This valve would have a stamped set pressure of 500 psig and a CDTP of
