 Finned Tubes for Convection Chambers by Qingdao Hexin Machinery Co.,Ltd.

A finned tube is a heat exchange element. In order to improve the heat exchange efficiency, fins are usually added on the surface of the heat exchange tube to increase the outer surface area (or inner surface area) of the heat exchange tube, so as to achieve the purpose of improving the heat exchange efficiency, such a heat exchange tube.

As a heat exchange element, finned tubes work in high temperature flue gas conditions for a long time. For example, finned tubes for boiler heat exchangers are used in harsh environments, high temperature and high pressure and in a corrosive atmosphere. This requires finned tubes to have high performance. index.
1), anti-corrosion performance (Anti-corrosion)
2), wear resistance (Anti-wear)
3), low contact resistance (lower contact resistance)
4), Higher Stability
5), anti-fouling ability
