We have to establish the correct code to validate the rigth WPS & PQR for a Hot Tap. in a marine plattaform pipe line. The thing is that ANSI/ASME B31.3 usualy applies for that kind of structures: BUT FOR DESING, and CONSTRUCTION, in that way it say nothing about hot atap. neither lines in operation (maintennance)
I thing we most look to API1104 APENDIX B.
I will apreciate the opinion of yours abot the apropiate code.
Thankyou.
The following standards could be the correct choice:
-API 570,"Piping Inspection Code - Inspection, Repair, Alteration, and Rerating Of In-Service Piping Systems".
-API RECOMMENDED PRACTICE 1107, "Pipeline Maintenance Welding Practices".
-The National Board Inspection Code (NBIC).
By the way, at January 19, 2002 I replied a post of Antonio about
of welding of seams welds of line pipe.

Dear friend:
The right standard that you need to review is the:
API; Publ. 2009, Safe welding and cutting Practices in Refineries, Gasoline Plants, and Petrochemical Plants.
API; Publ.2201, Procedures for Welding or Hot Tapping on Equipment in Service.
I hope those can help you,
Jorge Ruiz Castro
Another one that I forget,
API, Publ. 2201, Procedures for Welding or Hot Tapping On Equipment Containing Flammables.
This has a different title but same number, that the one I post before, I will check the hard copy and then confirn you.
Regards,
Jorge Ruiz Castro
