Allowable Stress Value for ASTM A155

Allowable Stress Value for ASTM A155


I'm working on old refinery revamping project, and I need to tie-in from ASTM A155 Gr.C55 CL.I.
The material has been replaced in 1978 so, I cannot find any allowable stress values.

Few days back in #thread292-16187: Old materials in new designs, A155 allowable stress value is available in ASME B31.3- 1976.
So, I'd like to purchase ASME B31.3-1976 Edition, however I cannot find where I can.

Please let me know how can I purchase any official code which shows ASTM A155 Gr.C55 CL.I. allowable stress values.

RE: Allowable Stress Value for ASTM A155

In lieu of trying to purchase an older specification, if you review ASME B&PV Code, Section II, Part D, the allowable stress for SA 671 Class 55 could be used.

RE: Allowable Stress Value for ASTM A155

I agreed.
I've also requested same, but Company rejected proposal.
Is there any official basis for the replacement of SA671 Class 55?
