[MW:23181] PQT for A333 Gr.6 pipe

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,
