FACE SEAL location
FACE SEAL location
(OP)
hello,
there are 2 mating flanges. One is Iron flange, and the other is aluminum flange.
Under internal pressure of 500 psi, and temperature of 200 C, should I design the face seal gland on the iron flange or the aluminum one?
Thanks ahead.

I think the face seal is probably not the best choice in this application, the high temperature application will tend to relieve compression since the fasteners will stretch. So torque specification will be a requirement in this application.
May I suggest a high durometer elastomer, something like 90/95. This has been my experience with blind flange applications during testing of ball valves. It is often difficult to achieve a seal and requires several hours of bolt torquing depending on the size of the flanges. I'm talking 48 inch here, so pretty beefy flanges.
Good luck with the application.
