Thanks BigInch & Auzie5.
Auzie5,
you mean that Chapter IX method of calculation will be highly advantageous for the material having high yield strength. Am I correct?

hi,
you are correct. both are different codes.
some specific reason will be there for considering only 2/3 of Yield strength. i am looking for that reason.

hi,
In B31.3, Appendix-A is providing allowable stress based on 1/3 of tensile stress or 2/3 of yield stress, whichever is lower.
why Appendix-K for chapter IX piping is considering 2/3 yield stress is allowable stress? Any specific reason?
