WPS with Impact & PWHT for non impact lines(non Sour service)
(OP)
Dear all,
We have a Sec IX qualified WPS for Sour service with impact & PWHT, I wonder can we use the Same for line which is non Sour and dosent require PWHT(Thickness-19mm).
Kindly clarify,
Thanks & Regards

Again Instead of qualifying a new procedure is it allowed as per codes to do the PWHT for line which is not havin any requirement as per the calss.
Pipe Class# API 5L, 60" X 19.05 Thick
Design Code# B31.3, Sea Water Service

Why would you want to do so? Qualifying a procedure without PWHT is economicaly beneficial to you in the long term.
