السلام عليكم ورحمة الله
Please advise us about the following
1. We are preparing a new WPS for in-service welding.
2. Our scope is mechanical sleeve type b pipeline repair.
3. The pipeline operation condition has several flow rates.
do we need to make individual WPS for each flow rate, or one WPS could be applicable for all the flow rates?
Thanks,,,

Dear Waqas
Use the attached test assembly (Figure-B-2) given in appendice-B of API-1104.
Then attached the pump with known flow rate with its "fluid in" nozzle during welding to simulate real welding conditions.
Using water during PQR test will qualify all the flow rates and flow media because water produces severe thermal conditions.

Dear Faisal,
Can you please advise me how to maintain water flow rate in test coupon during performing PQR.
What should be the arrangement in this regard.

MR. ANAS
YES
IF YOU WILL GO THROUGH APPENDIX –B IT CLEARLY GUIDES US THAT IN-SERVICE WELDING PROCEDURE WILL BE BASED ON THE API-1104 PLUS ALTERNATIVE/ADDITIONAL REQUIREMENTS GIVEN IN APPENDIX B.

Thanks Mr. Faisal and Mr.Joydev.
Is the sections 5/7 is applicable to in service welding ? How we can justify this?

Dear sir,
As per API 1104 the Dia range
A change from one specified OD group to another. These groups are defined as follows:
1) specified OD less than 2.375 in. (60.3 mm),
2) specified OD from 2.375 in. (60.3 mm) through 12.750 in. (323.9 mm),
3) specified OD greater than 12.750 in. (323.9 mm).
As per API 1104 the thickness range
A change from one specified wall thickness group to another. These groups are defined as follows:
1) specified pipe wall thickness less than 0.188 in. (4.8 mm),
2) specified pipe wall thickness from 0.188 in. (4.8 mm) through 0.750 in. (19.1 mm),
3) specified pipe wall thickness greater than 0.750 in. (19.1 mm).

Dear Experts,
I am in a situation to establish WPS for in service piping as per 1104 Annex B. The WPS is for a split tee tie in joint (Encirclement Tee)
Split tee ASTM A 516 Grade B
Header pipe 24" sch 60 (API 5L Grade B)
How to select the thickness range ?
How to select dia range ?
What are the essential variables ?
Please guide me to make a preliminary WPS.
Thanks & Regards
