I want to find out creep & rupture values for SA 335 P91 pipe
I want to find out creep & rupture values for SA 335 P91 pipe
(OP)
How to verify that Sr & Sc values given by customer in Test Certificate are matching with the ASME code.
I have gone through ASME Sec II Part A SA 335 specification but nowhere it's there. Even in ASME Sec II Part D only allowable stress at different temperatures are given.
These pipes are going to be used in power plant.
We refer ASME B 31.1
Please guide me whether in any code of ASME or ASTM these values at different temperatures are given or not?
If yes than in which code?
Thanking you in anticipation

Sc = creep stress

I would go to ASME Section II, Part D, Appendix 1 and review the requirements for establishing allowable stress values. Given Sr and Sc values convert to allowable stresses and compare

STRESS VALUES IN TABLES 1A AND 1B
