Re: [MW:27571] PQR (B31.3 vs B31.1)

Hi 

 

Pl refer ASME B31.1 , Chapter V – Clause 127.5 Qualification

 

Even though your construction / design code is ASME B31.1,  PQR requirements are as per Sec IX only..

 

You can use that PQR provided  if there is no specific additional testing requirements by client.

Dear 
PQR is as per ASME SEC IX not as per B 31.3.
So that you can use any where for P No 1.

Dear experts.

I have a PQR for P1 (GTAW, PWHT)qualified with Sec IX and B31.3. Is this PQR can used to supporte PQR in a power plant project that the code is B31.1.
