ASME SA312/SA312M

ASME SA312/SA312M covers seamless and straight-seam welded austenitic pipe intended for high temperature and general corrosive service. Steel pipe of ASME SA312/SA312Mshould be marked with the following info: Pipe size, wall thickness, specification, grade, seamless or welded, heat number, etc. Welded pipe of ASME SA312/SA312M should not use filler metal in automatic welding, large diameter pipe may have 2 longitudinal welds, pipe can be hot finished or cold finished.

Grade:TP347H,TP347,TP321,TP317L and so on.
