Longitudinal Finned Tube, I/L or U fins welded longitudinally onto the base tube. Also U-Bend execution possible.

Materials: 

Carbon Steels, Alloy Steels, Stainless Steel, Nickel Alloys, and others

Fields of application:

Chemical-, Petrochemical-, Oil-, Power Industry,Heat-Exchangers,Fired Heaters,Gas Coolers and Heaters,Tank Heaters

Manufacturing process:

The longitudinal I/L or U fins are welded onto the base tubes by resistance welding or welding with filler metal. U-Bend tubes with LFW, Fins also possible.

Advantages:

Increase of heat transfer rates for viscous liquids. Perforated fin type used whenever drainage of liquid from fin channels become a problem. Widely used in horizontal heat-exchangers.
