The fin strip is wound spirally onto the tube and welded continuously to the tube along the spiral root. Strong connection between fin and base tube, use at very high temperatures possible.

Materials: 

Base tube: Carbon Steel, Low Alloy Steel , Stainless Steel , Nickel Alloys , Nickel Alloys

Fins: Carbon Steel,Low Alloy Steel,Ferritic Stainless Steel,Austenitic Stainless Steel

Fields of application:

Fired Heaters, Heat Exchangers, Boilers, Pre-Heaters, Coolers, Heat Pipes, Dryers, Heaters.

Manufacturing process:

The fin strip is spirally wound onto the tube and welded continuously to the tube along the spiral foot. Welding process: HF, SF, TIG, MIG, MAG

Advantages:

Strong connection between fin and base tube, prevents loosening of fin due to heat stress, oxydization, corrosion etc. Use at very high temperatures possible.
