Are pressure vessels specified to use only GB/T24511 stainless steel plates, and not GB/T4237 stainless steel plates? However, the steel plate standard specified for petrochemical steel butt-welded pipe fittings SH3408 and large-diameter stainless steel pipe fittings is GB/T4237. May SH3408 standard stainless steel butt-welded pipe fittings be used in pressure pipelines?

One is the national standard, and the other is the petrochemical industry standard. I think manufacturing it according to the standard specifications will prevent any problems.

It is required by the regulations for pressure pipelines; whether it can be used depends on the standards for pressure pipelines. Not allowed
