JIS G3463 Stainless Steel Boiler and Heat Exchanger Tubes
JIS G3463 stainless steel tubes are widely used in boiler and heat exchanger applications, offering excellent corrosion resistance and high-temperature performance. These tubes are suitable for both internal and external heat exchange systems, making them ideal for use in chemical, petrochemical, and power generation industries.
Key Dimensions (in mm):
External Diameter: 19.05mm – 168.3mm
Wall Thickness: 2.0mm – 14mm
Length: Up to 19,000mm
The JIS G3463 standard covers a range of austenitic stainless steel grades, including both seamless and welded types. The welding methods typically used include automatic arc welding, laser welding, and resistance welding. However, these tubes are not recommended for use in heating furnace applications due to their design limitations.
