JIS G3463 stainless steel boiler and heat exchanger tubes

Stainless steel boiler tube JIS G3463
JIS G3463 boiler tube dimensions (mm):
External dimensions: 19.05mm – 168.3mm
Wall thickness: 2.0mm – 14mm

introduce:
JIS G3463 stainless steel pipe is used for internal and external heat exchange of the pipe. Its application areas are boiler superheater tubes, heat exchanger tubes, condenser tubes and other chemical and petroleum industries. It is not designed for heating furnace tubes. According to the manufacturing method, there are seamless steel pipes and welded stainless steel pipes (automatic arc welding, laser welding or resistance welding).
