High-frequency welding spiral fin tube

High-frequency high-frequency welding spiral finned tube is one of the most widely used spiral finned tubes, is now widely used in electricity, metallurgy, cement industry, waste heat recovery, and petrochemical industries. High-frequency welding spiral finned tube is wrapped fin strip on steel pipe, while using high-frequency current skin effect and proximity effect heating up the steel strip and pipe outer surface until plastic and melt state and then complete wound strip welding with certain pressure. Such high-frequency welding solid as a solid phase soldering. Compared with embedded, brazed, soldering (or overall hot dip galvanized) so compare with other methods, both in product quality (welded high fin, up to 95%), or the degree of automation and productivity, are much more advanced .
