Hello,everybody.

Greetings from China.

I am doing the stress analysis of a primary reformer furnace in a project of fertilizer factory, using CAESAR II. The operating temperature is 890℃, and the design temperature is 930℃.

I would like to know if ASME B31.3 is the proper codes to check the stresses in this system at such a high temperature. Or are there other validated methods that I can adopt to check the stresses?

Every expert please enlighten me somewhat.
