High Frequency Welding Spiral Fins Are Widely Used
- Aug 05, 2017 -

   High-frequency high-frequency Welding spiral fin tube is currently the most widely used spiral finned tube, is widely used in electric power, metallurgy, cement industry, waste heat recovery and petrochemical industries, high-frequency welding spiral fin tube is in the steel belt winding pipe at the same time, using the skin effect and proximity effect of high frequency current, the steel strip and the outer surface of the steel tube are heated, until the plastic state or melting, the welding is completed under certain pressure of the winding steel belt, this high-frequency welding is a solid-phase welding, which is embedded, brazing (or overall hot-dip galvanizing) Compared with the methods, whether in the product quality (the high welding rate of fin, up to 95%), or productivity and automation, are more advanced.
