Helical finned tubes are a highly efficient heat transfer element with helical fins. Its heat transfer area is several times to dozens of times that of the light pipe, which can enhance heat transfer, reduce flow resistance, and reduce metal consumption, thereby improving the economy and operational reliability of heat exchange equipment.
ASTM SA179 Spiral finned tubes
Spiral finned tubes have been widely used in heat recovery of boiler economizers, air preheaters and waste heat boilers, as well as heat exchange equipment in various fields such as chemical industry and pressure vessels. The capacity of the unit used in the boiler is also increased from small to large, and the application is increasing day by day. There are many professional manufacturers in China that can produce high-frequency welded and brazed spiral finned tubes, and the quality of finned tube production equipment and technology has reached the requirements of advanced foreign standards from the introduction, digestion and absorption to self-development, design and manufacturing.
Helical carbon steel finned tubes
The advantages of spiral finned tubes using finned tubes:
1) The heat exchange area is increased in the effective space to improve the heat transfer effect.
2) Reduce the occupied space of the heat transfer surface and make it smaller, especially suitable for quick-installed boilers.
3) Reduce equipment cost and improve equipment safety.
4) The running cost is reduced due to the reduction of the pressure drop on the water side, etc.
5) The rigidity of the finned tube is increased, which improves the shock resistance of the tube.
