Flange connection vs. butt weld on critical steam line.
Flange connection vs. butt weld on critical steam line.
(OP)
A steam line design condition at T=1050 F, P=1340 psig. Is it practical to have stop valve a flange connection instead of butt weld? What is a major concern if the flange connection being used from the stress point of view? Your input is appreciated.

RE: Flange connection vs. butt weld on critical steam line.
It's very dangerous to have flanged joints on steam at the pressure and temperature you mention. Any leak at the flanged joint would not be visible and personnel could be fatally injured by an escape. We never use flanged joints in such a steam line. Also the bolts would relax giving more problems with leakage.
