Integral Low Fin Tube Fabrication

The Tube and Fin are in same material. After rolling process, the outer surface of tube is formed with thread, which makes the finned tube have a higher heat transfer capacity.

Advantage

Low Fin tube provides 3 times the external surface area of bare tube.

It is helpful for the dropping of the cold condensate at the bottom of the tube, reducing the liquid film and thermal resistance but improving the heat transfer efficiency.

Integral low fin tubing yields numerous benefits for shell and tube heat exchangers including reduced size and cost for new equipment, increased performance of existing equipment. The cost of shell and tube heat exchangers can be reduced up to *0% through the proper application of low fin tubing.
Application
Low finned tubes are a reliable solution for controlling the temperature of gases and liquids, or for evaporating and condensing refrigerants. Thanks to their larger heat transfer surface area, they offer considerable potential to save in terms of materials and fill volumes, especially applicable to air and other gases on the fin-side and a fluid on the tube-side. Applied in heat exchanger for oil refinery and petrochemical plants, condenser and heat exchanger for petrochemical plants, condenser & evaporator for power plants,
