JIS G3463 Stainless Steel Boiler and Heat Exchanger Tubes
JIS G3463 stainless steel tubes are widely used in boiler systems and heat exchangers, offering excellent corrosion resistance and high-temperature performance. These tubes are commonly applied in superheater tubes, condenser tubes, and other heat exchange components within the chemical and petrochemical industries.
Dimensions (mm):
External Diameter: 19.05 mm – 168.3 mm
Wall Thickness: 2.0 mm – 14 mm
Length: Up to 19,000 mm
JIS G3463 stainless steel pipes are designed for internal and external heat exchange applications. They are not suitable for use as heating furnace tubes. The manufacturing methods include seamless and welded types, such as automatic arc welding, laser welding, or resistance welding. This ensures versatility and reliability in various industrial environments.
