ASTM A694 Flange material

[AnEngineer]

How do I find out to which material group (or Pressure Temperature rating table) of ASME B16.5 does ASTM A694 F65 belong? I can not find it in B16.5.

A reply will be appreciated.

You can't use B16.5 for comparison of similar material to obtain a pressure-temperature classification for this material. The reason is that ASTM A 694 is not endorsed by ASME B16.5.

What is your application (ASME B31.8 Gas Transmission and Distribution Piping Code)? If so, you need to review Chapter 1 and Chapter 4 for application of this material. It is endorsed in Appendix C of this Piping Code.

Thank You Metengr.
My application is pig launcher for gas line. Launcher material API 5L Gr 65. DP 1467 psi @ DT 150F.

I want to check ASTM A694-F65 600# flange rating at 150 F. But can not find it anywhere. What is the procedure?

Unfortunately, I see no other option other than to use a flange material that is endorsed by ASME B16.5 for this application. ASTM A 694 is not on the list of materials for use in flanges under B16.5, and I would not recommend trying to compare this material with any of the endorsed materials in B16.5.
