Use of TMCP plates for API5L PSL2 LSAW Grade X60 welded pipes in ASME B31.3

Use of TMCP plates for API5L PSL2 LSAW Grade X60 welded pipes in ASME B31.3

Use of TMCP plates for API5L PSL2 LSAW Grade X60 welded pipes in ASME B31.3

(OP)
Dear All,
We are in a big project where the sizes of pipes are very big 44", 54" and 64" with huge quantities.
Given the very tight schedule, the Contractor proposes us the use of TMCP plates for API 5L PSL2 LSAW Grade X60 welded pipes in ASME B31.3 as a process piping.
We have clearly understood the advantages and disadvantages of TMCP plates.
Knowing that the 5L API is accepted in the ASME B31.3 and the TMCP platforms have not been specified in this standards (no YES and no NO). In the 5L API, the TMCP plates are clearly cited (TMCP, Q&T, Normalized).
Can someone clarify us more so that we can decide whether or not we accept our Contractor's proposal for the use of TMCP plates for API5L PSL2 LSAW Grade X60 welded pipes in ASME B31.3 ?
Given the urgency, a prompt response is highly desirable.

Thanks in Advance

HR

RE: Use of TMCP plates for API5L PSL2 LSAW Grade X60 welded pipes in ASME B31.3

I think you've chosen the wrong forum.

This is really a pipelines or probably metal and metallurgy engineering in the materials engineers forums. Re-post there and red flag your own post to avoid double posting.

Whatever answer you get, you really need a proper materials engineer or consultant to provide you with enough technical assurance and provide some sort of written assurance about this.

If the pipes are very big with huge quantities then I'm sure the budget would allow this without which you're going to rely on advice from an internet forum??

Using API 5L pipes in B 31.3 normally isn't worth it because you can't really use the increased SMYS, but if for other reasons the contractor wants to use it then I can't see a big issue, but I'm not a materials engineer.

Remember - More details = better answers
Also: If you get a response it's polite to respond to it.
