Lord Fin Tube-High frequency welding of spiral fined tube

Fined tube is a kind of heat exchange element. In order to improve the heat exchange efficiency, fins are usually added on the surface of the heat exchange tube to increase the external surface area (or internal surface area) of the heat exchange tube, so as to achieve the purpose of improving the heat exchange efficiency.

High frequency welding of spiral Fined tube

High frequency welding spiral Fined tube is one of the most widely used spiral Fined tubes. It is widely used in power, metallurgy, cement industry waste heat recovery and petrochemical industry. High frequency welding of spiral Fined tube is carried out when the steel strip is wound around the steel pipe.

High frequency welding of spiral Fined tubeBy using skin effect and proximity effect of high frequency current, the steel strip and steel pipe outer surface are heated until plastic state or melting, and welding is completed under certain pressure of winding steel strip. This kind of high frequency welding is a kind of solid phase welding. Compared with inlay, brazing (or integral hot galvanizing), it is more advanced in terms of product quality (high welding rate of fins, up to 95%), productivity and automation.
