PWHT and NACE requirement

[cmryu]

We are reviewing requirement of PWHT related to NACE RP0472 and MR0103 Para4.2

PWHT requirement for clad materials in pressure vessel codes*
; It depends on the thickness and material of base metal. If the head (CS, 60mm thick with 316L SS clad) is one of the pressure vessel parts per ASME, the PWHT for whole vessel is mandatory requirement.
* ASME Sec. VIII, Div.1, UCL-34

However, I would like to confirm how about Carbon Steel material, Is this also comply with clad material.

You need to repost this request in either forum292 or forum794 or forum330. Pick one, not all three. Don't cross-post. I'd recommend the ASME Code issues forum, but you'll probably get similar responses from the other two.
