PWHT of TMCP treated P460 ML1

01/19/2011 1:44 AM

Dear All,

Design code ASME sec viii, div 1,

Pig trap barrel material P460 ML1 (TMCP treated) , Thickness 40mm
welded to
A765 End closure, Thickness 60mm,

Since CE value of P460 ML1 is 0.46% and design code mandate PWHT with nominal thickness (40mm),

Can somebody give me an insight of PWHT effect on P460 ML1 mechanical properties and appropriate PWHT temperature?

Regards
Manpreet Singh
