What type of gasket should be used for the RJ sealing surface of the flange at a pump outlet pressure rating of 2500#? Should it be octagonal or elliptical?
For high pressure levels, it is appropriate to use flanges with RJ faces and metal gasket rings; that’s the right choice. As for whether octagonal or elliptical gaskets should be used, it seems there are no specific requirements. The selection mainly depends on temperature and material, right? Seek guidance from those of equal expertise to provide support
The octagonal gaskets are used in all the high-pressure units of the LPEC cl2500 model
It is recommended that the poster use an octagonal gasket; it is easier to achieve a good seal with an octagonal gasket for the RJ-type sealing surface. As for the material, it just needs to be the same as that of the pipe
Reply to 4# Xiao Luotou: The material of the pipe is ASTM A182 F316L, and the material of the flange is SA-182 Gr.F51 CL2. What would be a good material for the gasket used with this 2500# flange?
