Welding API 5L Pipe
Welding API 5L Pipe
(OP)
There is a project where API 5L-B is being used for clean storm water piping in a local refinery. There was not enough material ordered to finish the project. I have been asked if subtituting API 5L-X42 is a viable option for the shorted materials.
My question is will there be any general issues to consider regarding weld procedures by joining the grades B and X42 materials (i.e., p-number, group number). I know these materials are not covered in ASME Section II. I do not know what WPS/PQR that is being used to join the grade B-to-grade B pipe, but are there any issues that may arise that will require a different WPS/PQR to be used by joining grade B-to-grade X42?

I suppose you can use the welding process bellow after qualifying it.
1 GTAW ER 70S-G
2 SMAW E 7018-1
remaining passes with SMAW E 7018-1
