SA312 TP304H Stainless welded Pipe Taiwan Project

We use our facotry SA312 TP304H stainless welded pipe at Taiwan project and got a good reputation of quality. SA213 TP 304H welded tubes AND SA312 TP 304H welded pipes.


SA312 TP304H Welded pipe standard: ASME SA312 specification covers seamless pipe and welded pipe for austenitic stainless steel. These high performance austenitic stainless steels have a fully austenitic microstructure in the quench annealed condition.


RYIN Stainless Welded pipe factory produce and export of stainless steel seamless and welded pipes per ASME SA312 in Grade of TP304H/304L, TP316/316L/316Ti, TP321/tp321H, TP SS347H, TP317L, TP904L TP309S/H TP310S/H and SS446 among other special grades.
