　　Spiral finned tube radiator for Jiaao vegetable greenhouse

　　High frequency welded finned tube radiators can be applied to vegetable greenhouse heating, flower greenhouse heating, drying room finned tube radiators, and industrial workshop heating. The finned tube radiator is made of carbon steel material, which has high pressure resistance, and the steel winding has good toughness and is not easy to break.

　　Customized high-frequency welded spiral finned tubes for finned tube radiators are currently one of the widely used spiral finned tubes, widely used in waste heat recovery in the power, metallurgy, cement industries, as well as petrochemical industries. High frequency welding of spiral finned tubes is achieved by using the skin effect and proximity effect of high-frequency current to heat the steel strip and the outer surface of the steel tube while winding it around the steel strip, until it reaches a plastic state or melts, and welding is completed under a certain pressure of the wrapped steel strip.

　　This high-frequency welding is actually a solid-state welding. Compared with methods such as inlay, brazing (or integral hot-dip galvanizing), it is more advanced in terms of product quality (high welding rate of fins, up to 95%), productivity, and automation. The production principle of the three roll oblique rolling integral spiral finned tube is as follows: a core rod is lined inside the light tube, and the seamless steel tube is processed into fins on its outer surface through the hole cavity composed of the rolling groove and the core head by the rotation of the rolling blade.
