Product Description

High Frequency Finned Tube

The basic principle of high frequency Fin Tube is to take the seamless steel tube on the outer packing band with a certain distance (strip perpendicular to the outer surface of the tube) and high-frequency current welding as the heat source. By using the skin effect and electrical effect of high-frequency current, the local heating tube, the steel strip and the contact surface area to be welded can be plastically welded. At the same time, the forging force of finned tube is applied to the metal oxide and the plastic form of the contact outside of the excess melt, so as to realize the combination of solid atoms between the steel tube and the finned material.

High frequency finned tubes features

The high-frequency welding finned tube uses the skin effect and proximity effect of the high-frequency current to heat the steel strip and the outer surface of the steel tube while the steel strip is wound around the steel tube until it is in a plastic state or melted. Under a certain pressure of winding the steel strip Finish welding. This high-frequency welding is actually a solid phase welding. Compared with inlay, brazing (or overall hot-dip galvanizing) and other methods, it is more advanced in terms of product quality (high fin welding rate, up to 95%), productivity and automation . Compared with Intergral High Finned Tube, G Finned Tube, Intergral Low Finned Tube, Longitudinal Finned Tube

(1) High production efficiency, continuous winding production;

(2) Low cost, it depends on the characteristics of high-frequency welding itself — skin effect heating workpiece surface, to achieve the purpose of welding, welding process does not need to add any filler metal materials;

(3) Since the high-frequency current only passes on the shallow surface of the steel tube, the welding heat affected zone is small, so the additional wall thickness caused by this need not be considered in the design calculation; No heat treatment is required after the workpiece is welded.

(4) Solid welding, in the equipment configuration reasonable, process parameters perfect under the circumstances, can achieve between the fin and steel pipe welding firm, can withstand frequent open, shutdown caused by the thermal shock wave.
