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 units used in boilers is also increasing from small to large, and the applications are increasing day by day. There are many professional manufacturers in China that can produce high-frequency welding and brazing spiral finned tubes, and the quality of finned tube production equipment and technology has reached the requirements of foreign advanced standards from the introduction, digestion, absorption to self-development, design and manufacture. .
Advantages of 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 reduce its volume, especially suitable for fast-installed boilers.
3) Reduce equipment cost and improve equipment safety.
4) Due to the reduction of water side pressure drop, etc., the operating cost is reduced.
5) The rigidity of the finned tube is increased, which improves the anti-seismic ability of the tube.
