[MW:24491] Procedure Qualifications as per API 1104

Hi all welding experts

I have to qualify some procedures as per API 1104 and I have least knowledge about this specification.....

First I will detail my Product

1).I have Pipe( API 5L X65 MS) to be welded with a flange(ASTM A 694F65) 75deg groove angle butt joint( V groove 75 deg included angle)

2) SamePipe will be welded with a nozzle
(ASTM a694 F65) set on joint groove fillet weld.

As per API 1104 Clause 5.4.2.2 (c) for question no. 1, whether I have to make two pqr of F65 to F65 and X65 to X65 combinations with V groove 75 deg included angle??
and
as per API 1104 Clause 5.4.2.3 for question no 2 both above PQR's will suffice the requirement of nozzle to pipe welding...??


Regards

Dhanush
