Machining Ustom High Frequency Welded Finned Tubes 

The high-frequency welded spiral finned tube is a high-efficiency heat transfer element, and its heat transfer area is several times or even dozens of times that of the light tube. Strengthen the heat dissipation, reduce the consumption of metal, and improve the cost performance. Now widely used in petrochemical industry; metallurgical industry; rubber industry; printing and dyeing industry; food industry; automobile industry, etc. During the installation process, there are fewer contact points, the installation is more convenient and the cost is reduced, and the leakage of the finned tube is also reduced, so the working life of the spiral finned tube is longer. High Frequency Welded Fin Tube uses solid resistance heat as energy source. During welding, the resistance heat generated by high-frequency current in the workpiece heats the surface of the workpiece welding zone to a molten or nearly plastic state, and then applies (or does not apply) the forging force to achie…
