I try to design Relief Valve for my job.
Pressure 50 bar, Temperature 490 degC
My assumsion is Flanged because its less than 4500# (ASME B16.34 i think). But for High Pressure and High Temperature my friend recommended Butt Weld. Any one know reference for this case? or Any one ever install SRV for that operating condition? Pls give suggestion thank you
