Reducing Flange Ratings
Reducing Flange Ratings
(OP)
2" s.s. nozzle in shell designed for 150 psig @ 400F jacketed by a 3" c.s. nozzle designed for 260 psig @ 450F
I can't find anything in ASME Sect XIII Div 1 that addresses this specifically => What tells me the reducing flange has to be rated to withstand the jacketing nozzle pressure and temp or not? I can see it both ways.
I hope that makes sense. Thanks for the help.

RE: Reducing Flange Ratings
Assuming the flange itself is not exposed to the jacket pressure I would design for 150 psig.
Assuming the flange itself could be exposed to the jacket temperature I would design for 450 F.
Thereby you not only can see it both ways, you can have it both ways.

RE: Reducing Flange Ratings
American National Standard ANSI B16.5 contains pressure/temperature ratings
