B31.8 and wphy65
(OP)
i must calculate a fittings under B31.8
the material is req. as MSS SP WPHY65
THIS FITTING WORK AT 105°C IT MEANS THAT THE CUSTOMER DON'T TAKE IN TO ACCOUNT THE TEMP. DERATING, AND USE A YIELD STRESS OF 448 N/mm (ROOT)
I SUPPOSE THAT IS NOT CORRECT, BUT WHERE I CAN FOUND THIS VALUE ??
