High-frequency welding serrated finned tube is to open the teeth of the steel strip before high-frequency welding of the fins, and then use the skin effect of high-frequency current to weld the serrated steel strip to the steel pipe at high temperature. The finned tube produced by this process has high welding fastness and good heat exchange efficiency. In addition, after the fins are opened, the turbulence effect is increased, the heat exchange efficiency is improved, and the dust accumulation can be better prevented.

Radiator Serrated Type Finned Tube for Air Heat Exchanger

Serrated high-frequency welded finned tube is a kind of wear-resistant, new and high-efficiency heat transfer raw material. The frequency power source is used as the heat source, and the seamless steel pipe and its steel strip are reasonably heated at the same time, so that they will be welded together and integrated.

Serrated high frequency welded finned tube

The installation and operation of the serrated high-frequency welded finned tube is convenient and economical, and the connection points are reduced, so that the installation of the equipment will be more economical and convenient, and to a certain extent, the probability of water leakage at the connection point is also reduced, and the equipment maintenance is easy.After the installation is successful, most of them do not need to start maintenance.

Serrated High Frequency Helical Finned Tubes

The application of serrateded high-frequency welded finned tubes has high working efficiency. In the process of starting manufacturing, the seamless steel tubes and fins are wound and welded in full contact, and the total heat dissipation area is more than 8 times that of the bare tubes. The interior will become smoother and the resistance of the flowing water inside is very small.
The serrated high-frequency welded finned tube has a long service life, and the mechanical strength of the fin and the tube will be higher at the beginning. The tensile strength of the equipment can reach more than 196Mpa, and the inside and outside of the tube can be processed by galvanizing.
