Helical finned tubes are a highly efficient heat transfer element with helical fins. Its heat transfer area is several times to dozens of times larger than that of the light pipe, which can improve heat transfer, reduce flow resistance, and reduce metal consumption, thereby improving economy and reliability. operation of the heat exchange equipment.
Spiral finned tubesThey 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 also increases from small to large, and the application increases day by day. There are many professional manufacturers in China who can produce high-frequency brazed and welded spiral finned tubes, and the quality of finned tube production equipment and technology has reached the requirements of advanced foreign standards since the introduction, digestion and absorption to self-development, design and manufacturing.
The advantages of spiral finned tubes using finned tubes:
1) The heat exchange area increases 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 installation boilers.
3) Reduce equipment cost and improve equipment safety.
4) Running cost is reduced due to reduced pressure drop on water side etc.
5) The rigidity of the finned tube is increased, which improves the shock resistance of the tube.
