we have obtained ISO 9001, ISO 14001, ISO 45001, CE, AAA-level credit rating certification, etc.
This specification covers seamless, straight-seam welded, and heavily cold worked welded austenitic stainless steel pipe intended for high-temperature and general corrosive service. 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 service at temperatures where creep and stress rupture properties are important
Types ASTM A312 Pipe
ASTM A312 Seamless Pipe
Pipe should be made from stainless steel billet in hot rolling or cold drawn, no any welding process during manufacturing, seamless pipe has better pressure to withstand, annealing solution and pickling finishing condition, applied for high temperature and corrosion environment.
ASTM A312 Welded Pipe
No additional metal using automatic welding process for welded pipe, made from stainless steel strip or plate, both single welding and double welding for option, smail diameter and arge diameter are available, annealing pickling finish.
Heavily Cold-Worked (HCW) Pipe
Pipe shall be made by applying cold working of not less than 35 % reduction in thickness of both wall and weld to a welded pipe prior to the final anneal. No filler shall be used in making the weld. Prior to cold working, the weld shall be 100 % radiographically inspected.
Final Finishing:
Solution Annealed & Pickled
