JIS G3463 Stainless Steel Boiler and Heat Exchanger Tubes

JIS G3463 stainless steel boiler tubes are widely used in heat exchange systems for both internal and external applications. These tubes are specifically designed for use in boilers, superheaters, condensers, and other heat exchangers within the chemical and petroleum industries. However, they are not intended for use in heating furnace tubes.

They are available in a variety of dimensions to suit different industrial needs:

  • Outer Diameter: 19.05 mm – 168.3 mm
  • Wall Thickness: 2.0 mm – 14 mm
  • Length: Up to 19,000 mm

Manufacturing methods include seamless and welded pipes, with welding techniques such as automatic arc welding, laser welding, or resistance welding being commonly used.
