ASTM A312 welded stainless steel pipe (304/316) from TPMC is manufactured by automatic welding with no filler metal, featuring a longitudinal seam, precise dimensions, and lightweight construction.
As austenitic stainless steel, it offers excellent formability, non-magnetic properties, and superior corrosion resistance. Suitable for high-temperature and general corrosive service, it is widely used in petroleum, chemical, marine, automotive, and mechanical structural applications.
