Heat Exchanger Carbon Alloy Aluminium and Stainless Spiral Fin Tube
Spiral finned tube is a high-efficiency heat transfer element with spiral fins. Its heat transfer area is several times to tens of times that of the light pipe, which can enhance heat transfer, reduce flow resistance, and reduce metal consumption, thereby improving the economics and operating reliability of heat exchange equipment. At present, spiral finned tubes have been widely used in various boilers. Spiral finned tubes can be manufactured by a variety of methods. At present, finned tubes used in heat exchange equipment such as boilers and pressure vessels mainly have the following manufacturing methods: high-frequency resistance welding spiral finned tubes, brazed spiral fins Tube and integral spiral finned tube.

Advantages:
Advantages of using finned tubes:
1) Increase the heat exchange area in the effective space and improve the heat transfer effect.
2) Reduce the space occupied by the heat transfer surface and reduce its volume, especially suitable for quick installation of boilers.
3) Reduce equipment cost and improve equipment safety.
4) The operating cost is reduced due to the reduction of the water pressure drop.
5) The rigidity of the finned tube is increased, and the seismic resistance of the tube is improved.
