If you want to use pipes, you can run the PQR using A333 Gr 6 and API 5L X65 pipes , both are P1G2 materials. Hope there is impact test requirements.
Dear Experts,
 
In our project, we have to establish a  WPS /PQR for A333 Gr 6 Pipe (P-1,Group-1) and Flanges A350 LF-2 (P-1,Group-2).   Process - GTAW+SMAW (with ER 70S-2 and E7018-1).
 
How to conduct/establish one combined PQT with P-1,Group-1 to P-1,Group-2 ??
 
Can we make two PQT separately of below options :-
 
One Pipe to Pipe in 6G position and other any Plate to Plate in 4G/3G position of which Tensile Strength 70 ksi) - Is it acceptable  as per ASME Sec-IX?
 
 
Please clarify.
 
Thanks in advance,
 
R.K.Samanta
