HIGH FREQUENCY RESISTANCE WELDED Finned Tube
The High Frequency Resistance Welded Finned Tube is a high-frequency current that is introduced into the workpiece, and the welding contact surface is melted or semi-melted by the electric current generated by the contact surface of the welded joint and the adjacent portion. State, then apply appropriate pressure to the weld contact surface to complete the welding of the finned tube.

SERVICE LIFE
The High Frequency Resistance Welded Finned Tube is performed by melting at the contact of the two metal surfaces, and the welding rate is good. The corrosion resistance of the weld metal is more than doubled than that of the brazing, and the fin can be greatly improved. The service life of the tube. However, due to poor welding, long-term use is prone to cracking of the weld, which causes the fins to disengage from the pipe, thus affecting the heat transfer efficiency, and the finned tube has to be replaced.
