SA312 TP310H Stainless welded Pipe Taiwan Project
We use SA312 TP310H stainless welded pipe at Taiwan project and got a good reputation of quality.

SA312 TP310H 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 TP310H/304L, TP316/316L/316Ti, TP321H, TP SS347H, TP317L, TP904L TP309S/H TP310H/H and SS446 among other special grades. Stainless steel seamless tubes are available in compliance with ASME A213 and ASME sa312.The main  grades are 304/304L, 316/316L 321/321h 310s/310h 309h/309s in standard tube sizes and wall thicknesses. We offer custom size cold drawn stainless-steel pipes and stainless-steel tubes to our customers. Generally stainless-steel pipes and stainless-steel tubes are available in standard OD or NB sizes. However, with our tube processing capabilities we can offer any custom size outside DIA and thickness to our customers.

Our TP310H Stainless Steel Welded pipe manufactured from cold-forming process using coils of steel sheet with automated spiral welds. Great strides were made in quality control, testing, joints and protective coatings. Welded steel pipe is available in wide ranges of sizes and properties of the steel. These ERW Pipes carry high strength, ease of installation, high flow capacity, leak resistance, long service life, reliability and versatility, and economy.


The welding process itself also plays a critical role in controlling heat input and cooling, and thereby corrosion resistance and distortion. TIG welding is traditionally used for welding stainless steel tube and pipe, and remains the optimal solution for extremely high purity applications on tube or pipe at or below 6-inch diameter and schedule 10 wall thickness. The preferred method for high purity food-grade stainless steel is an autogenous TIG square butt weld. The ability to fuse the pipe without adding any filler metal helps keep heat down and eliminates any chemistry changes that could be created by the added filler metal.
