Basic allowable stress for ASTM A 928 UNS S32750

[boxtobox]

Hi all,

I'm developing wall thickness calculation for 18" ASTM A 928 UNS S32750 pipe, but I can't find basic allowable stress for this material in ASME B31.3. Is it possible to use the ASTM A 790 basic allowable stress value for A 928? Please kindly advise.

Regards.

hello,

I would do this ie. revert to ASTM A790 S32750 as basic allowable stress is stated in ASME B31.3 and also covers the welding type in ASTM A928 ie reference table A-1B EFW factor 1.0 when 100% X-ray.

Cheers
