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
