You mean we can select either 14" 150#, 300#, 600#, 900#, or 1500# RTJ ring gasket for a 14" 2500# flange (w/ blind) designed per Appendix 2? That seems doesn't make sense. Looking forward to your reply. Thank you!
brkmech1234, thank you very much for your reply.
Based on what you said, through 14" 1500# RTJ ring gasket is for 14" 1500# flange (say the MAWP of the flange is 3170 psi at 400 F for SA105 material), the gasket itself can have pressure rating greater than 5000 psi. Do you have any reference...
Brkmech1234, thank you for your valued input.
Let me take a example for this: We have a pressure vessel, design pressure 5000 psi at 400 deg F. all other nozzle sizes less than NPS12" (these nozzles will have piping connections,) we can select 2500# flanges per ASME B16.5, and there are 2500#...
Does anybody can help me out?
I am looking for RTJ Ring Gaskets for NPS 14 Thru 24 flanges with design pressure 5000 psi @ 400 degree F. Per ASME B16.5, the allowable pressure for CL 1500 is less than 5000 psi.
As 14"-24" CL2500 flanges are not listed in any Codes, the high pressure flanges...
