Serrated Fin Tube is a fin tube that is made by first cutting the steel strip before high-frequency welding the fins, and then using the skin effect of high-frequency current to weld the cut steel strip to the steel tube at high temperature.

It is a new type of heat exchange material that is wear-resistant and energy-saving. The fin tube produced by this process has high welding strength and good heat exchange efficiency. În plus, the fins are cut to increase the turbulence effect, improve the heat exchange efficiency, and better prevent dust accumulation.
