Longitudinal Finned Tube, I/L, or U fins welded longitudinally onto the base tube. Also, U-Bend execution is 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, 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 is used whenever drainage of liquid from fin channels becomes a problem. Widely used in horizontal heat exchangers.
