ASTM A312 specification covers seamless, straight-seam welded, and heavily cold worked welded austenitic stainless steel pipe intended for high-temperature and general corrosive service.
ASTM A312 Grades TP304H, TP309H, TP309HCb, TP310H, TP310HCb, TP316H, TP321H, TP347H, and TP348H are modifications of Grades TP304, TP309Cb, TP309S, TP310Cb, TP310S, TP316, TP321, TP347, and TP348, and are intended for high-temperature service. We produce ASTM A312 TP304 seamless stainless steel pipe in various sizes, The pipe conforms to ASTM A312 pipe specifications, and the TP304 seamless pipe has good corrosion resistance.
ASTM A312 Seamless Pipe
Stainless steel seamless pipe should be made from stainless steel billet in hot rolling or cold drawn, with no welding process during manufacturing. ASME SA312 SS Seamless tubing has better pressure to withstand, annealing solution and pickling finishing conditions, applied for high temperature and corrosion environments.
ASTM A312 Welded Pipe
No additional metal using automatic welding process for stainless steel welded pipe, made from stainless steel strip or plate. SS EFW ERW pipe both single welding and double welding for options, small diameter and large diameter are available, annealing pickling finish.
A312 SS Pipe Heat Treatment
ASTM A312 pipe shall be furnished in the heat-treated condition in accordance with the required heat-treating temperature and cooling requirements, pipes shall be individually quenched in water or rapidly cooled by other means (direct quenched).
