hello every body
we want to construct a 80" pipe with plate with one weld seam.
the owner wants from us to use a plate which should be equivalent to ASTM A671 CB60 CL.10.
please tell me a plate specification
80" would commonly be spiral welded, you can do it with one longitudinal seam, but be warned that the pieces will be short since they are limited by the width of the plate. That will be a lot of curcumriencial welds.
Take the UNS and strength and start comparing that to what people are offering.
But be aware of any special properties (or testing) that A671 requires.
Material ASTM A671 CB60 CL.10 is a fusion welded pipe, that mean make from plate.
I have a look in ASME IX, material fall P-Number 1 and Gr-Number 1, so this is may offer equivalent plate material P-No. 1 and Gr.-No. 1 such API 5L, ASTM A516 Gr. 60 or other plate the same minimum tensile 60 KPSI. Don't forget to get approved from your engineering and your Client.
