Considering Pipeline, API 1104 code was considered for below.

1. One PQR for X60 material
2. Another PQR for X65 material to be qualified'

If you qualify PQR on 6 inch wall thickness 7.92 mm then it qualifies from wall thickness 4.8mm to 19.1mm and no Limitation on Diameter

Thanks & Regards

Hello 

i want to prepare a WPS for pipeline work with base metal API 5L X60 - X65  SMAW 

for the test coupon i want to use 6" with thickness = 7.92 mm 

want to know the minimum and maximum range for size and thickness used for the PQR

By below mail was based on API 1104 Code which considers yield strength as essential variable.

From your below mail I understand you are using ASME Sec.IX (correct me of I am wrong).

Acc to ASME Sec.IX one PQR is sufficient for API 5L X60 - X65 as they both fall under P1 Gr.2.

Acc to ASME Sec.IX thickness range qualified is 1.5mm to 15.84mm

Thanks & Regards

tnx for your reply 

So its mean that i should prepare two different Test coupon or what 

and for the maximum thikness of base metal from QW 451.1 THEY MENTION THAT  T QUALIFIED X 2  ITS MEAN 7.92 X2 = 15.84 mm

Instead of being confused, first you should know what is your Job.

Then the design  Code ASME B 31.4 or ASME B31.8


Snap shot provided below for you to decide.

Since you mention about range I assumed you are qualifying Wps for the range X60 - X65.

If it is a Joint between X60 - X65. then u can use the PQR for X65.

Thanks & Regards
