What is a fin tube?

- Oct 16, 2019-

A finned tube is a heat exchange element. In order to improve the heat exchange efficiency, the outer surface area (or inner surface area) of the heat exchange tube is generally increased by adding fins on the surface of the heat exchange tube, thereby achieving the purpose of improving heat exchange efficiency, such a heat exchange tube.


As a heat exchange component, the finned tube works for a long time under high temperature flue gas conditions. For example, the fin tube of the boiler heat exchanger has a harsh environment, high temperature and high pressure and is in a corrosive atmosphere, which requires high performance of the finned tube. index.

1), anti-corrosion performance (Anti-corrosion)

2), wear resistance (Anti-wear)

3), low contact resistance (lower contact resistance)

4) High Stability

5), anti-ashing ability
