serrated finned tube

The high-frequency welded serrated finned tube is to open the steel strip before the high-frequency welding of the fins, and then use the skin effect of the high-frequency current to weld the serrated steel strip to the steel pipe at high temperature. The finned tubes produced by this process have high welding fastness and good [...]
