The High Frequency Welded Fin Pipe is one of the most widely used spiral fin pipe. It is widely used in waste heat recovery in electric power, metallurgy, cement industry and petrochemical industry.

The High Frequency Welded Fin Pipe is used to wind the steel pipe while using the skin effect and the proximity effect of the high-frequency current to heat the outer surface of the steel strip and the steel pipe until plastic state or melting, and a certain pressure on the steel strip is wound. Finish the welding. This high frequency welding is a solid phase welding. Compared with inlaying, brazing (or integral hot-dip galvanizing), it is more advanced in terms of product quality (high fin weld width, up to 95%), productivity and automation.
Fin pipes currently used are mostly wound type, high frequency welded, brazed spiral finned steel pipes. The High Frequency Welded Fin Pipe has the advantages of long service life, stable heat transfer performance and obvious energy saving effect, and has become a new generation of the above three types of spiral finned steel tubes.
