Re: [MW:30727] BASE METAL THIKNESS FOR PQR

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.

IM CONFUSED , NORMALLY WHAT I SHOULD TO USE ASME 9 OR API 1104  

Le jeudi 9 avril 2020 07:02:56 UTC+2, gerr...@yahoo.com a écrit :
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

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

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
