Hi,
If it is for standards pipe supports, then you can include it the same ITP. Acceptance criteria shall be as per ASME B31.3. But if it is a separate steel structural like pipe rack which is not as a direct part of piping, then you need to have a separate ITP & WPS/PQR as per AWS D1.1.
You cannot refer AWS D1.1 acceptance criteria for a joint welded by SEC IX WPS.
regards,
LALU

Dear experts--We have an ITP for structural welding in that WPS & PQR prepared as per ASME SEC IX.my question is
- NDE acceptance is mentioned as ASME B 31.3 which is related process piping.
- Can we use AWS D 1.1 as acceptance criteria?.
- Can we two different types of codes in same ITP.such like that ?
