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 . (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. High frequency finned tube specifications Product specification: ∮ 25-219mm Fin thickness: 0.8-2.5mm Fin pitch: 4-35mm Fin width: 10-25mm Effective welding length: ≤15 m Bending radius of finned tube: 50-300mm Finned tube welding rate: more than 95% High frequency finned tube Material Standard Fin material: Aluminum 1060, 1050, 1070, 6063,6061,3003 High frequency finned tube applications High frequency welding fin tube is widely used in petrochemical, machinery, metallurgy, rubber, printing and dying, medicine, food, power plants, passenger cars, drying and other industrial heating and cooling, is the convection section of cracking furnace, transform furnace, heat exchanger, air preheater and economizer, crystallizer, radiator, and the optimal heat transfer of heat pipe technology components. The advantages of high frequency welded fin tube, especially the steel fin radiator is widely used in office buildings, residential buildings, hotels, workshops and other industrial and civilian construction industry, with good heating effect, is the traditional cast iron, plate radiator replacement products.
