I know most of the question deal with AWS certification, but I have a question about ASME BPV Section IX.
We have a PQR that was competed on SA 312 Pipe. By code definition this would be a P8 to P8 grouping. I would like to complete the WPQ on the actual product which would be a A182 F316/F316L to A351 Grade CF3M. I know the A182 is a S8 group, but I believe the A351 Grade CF3M falls in unassigned group since I can't find it in QW-422. I know this material selection is valid for PQR.
My question what is the range qualified on WPQ? If the material was P8 to P8, the range would be P-no./S-no. 1 thru 11, 34, 4X. But since this has an S# and an unassigned, my guess is S-no 1 thru 11 to A351 Grade CF3M but I am not for sure. Does any have any advice?
