Spiral finned tubes Description
Spiral finned tubes are heat exchange components that enhance heat transfer efficiency through spiral fins, serving as energy-saving elements in boilers, pressure vessels, and other equipment. Their heat transfer area can be several to dozens of times larger than that of bare tubes. Manufacturing processes include high-frequency resistance welding, brazing, and rolling forming. Among these, the integral spiral finned tube achieves one-piece forming of fins and base tubes through hot rolling, extending its service life by more than three times.
Advantages of using Spiral finned tubes:
Increases the heat exchange area within the effective space, improving heat transfer efficiency.
Reduces the occupied space of the heat transfer surface, thereby shrinking the volume-especially suitable for packaged boilers.
Lowers equipment costs while enhancing safety.
Reduces operational costs due to factors like decreased water-side pressure drop.
Increases tube stiffness, improving seismic resistance.

Functions and Applications
Enhanced Heat Transfer Efficiency: The spiral structure increases the heat dissipation area and disrupts the fluid boundary layer, significantly improving heat exchange efficiency. It is suitable for heating, cooling, evaporation, and other scenarios.
Improved Structural Strength: The rigidity of spiral finned tubes is more than three times higher than that of bare tubes, making them ideal for high-temperature and high-pressure environments.
Extended Service Life: The integral spiral finned tube, manufactured through hot rolling for one-piece forming of fins and base tubes, extends service life by more than three times.
Industrial Applications:
Petrochemical Industry: Used in heat exchange equipment for furnaces and reactors.
Power Industry: Applied to boiler superheaters and reheaters to enhance steam temperature and pressure.
Metallurgical Industry: Heat exchange processes in steelmaking and iron production.
