Customized Processing Steel Products Heat Exchanger Parts HFW Fin Tube

High-frequency welded helical finned tube is a highly efficient heat transfer component, it consists of steel fins wrapped helically around steel pipe, and continuously welded using the high frequency electric current welding process so as to reduce the flow resistance and the metal consumpition, improve the efficiency of heat transfer equipment and operating reliability.

The heat transfer energy is more than 6-10times higher than the bare tubes.

Tube material: seamless steel, carbon steel

Fin Material: Carbon steel; stainless steel

Product Specification :

Application :

High-frequency welding spiral finned tube is one of the most widely used spiral finned tubes. It is now widely used in waste heat recovery in the power, metallurgy, cement industry, petrochemical industry and other industries. The high-frequency welding spiral finned tube is to use the skin effect and proximity effect of the high-frequency current to heat the outer surface of the steel strip and the steel pipe while the steel strip is wound around the steel pipe, until the plastic state or melting, a certain pressure on the wound steel strip Complete welding next. This high-frequency welding is actually a solid-phase welding. Compared with inlaying, brazing (or integral hot-dip galvanizing) and other methods, it is more advanced in terms of product quality (high welding rate of fins, up to 95%), productivity, and degree of automation .

Package :

Packing with Plastic Mat, Waterproof Paper , drying agent/desiccant and plastic cap .

1) For light ,short fin tubes ,we use exporting wooden case

2)For heavy, long fin tubes ,we use iron frame wooden case

3)On the top of the package ,we weld more square steel to protect the package from damage during the sea or air shipment
