Low FinTube Product Description:


Integral low fin tube developed as a method of increasing heat transfer performance of fluids while minimizing the size also cost of the Heat Changer The fin tubes can improve the thermal performance of a heat exchanger without change shell size, flow arrangement or re-positioning of tube. The external surface of the tube is increased by the formation of "low fins".The fin is produced by being rolled from the wall of the tube and is therefore integral with the tube itself. Due to fin rolling the wall thickness beneath the finned section is reduced compared with the plain ends. The bore of the fin section is slightly reduced.Most tubular materials can be finned, however hardness of the material usually determines whether the tubes suitable for finning.



Manufacturing Process:


Low fin (integral) tube is an extruded tube consisting of short low fins, the fins are rolled out from the outer wall of the plain tube by rollers, and the tube and fins are in the same piece of tube.

Low Finned Tube(Aluminum Fin Tubes) Properties:


1.The processing cost is low;

2.The low-finned tube is formed by directly rotating the steel tube to form fins, so there is no need to worry about falling off even if it is bent later.

3.Has excellent durability and anti-vibration performance.

4.Increase the external surface area of the bare tube by 2.5-3 times, improve the efficiency of the heat exchanger, and improve the performance of the existing heat exchanger.

5.The reduction in space and weight is very valuable for offshore production or high altitude distillation columns. Low-fin technology can transform large shell and tube heat exchangers into compact heat exchangers

6.It has a wide range of applications and can strengthen the evaporation, condensation, gaseous heat transfer and liquid heat transfer of the medium on the shell side.

1. What is the fin efficiency?

Fin efficiency is defined as the ratio of actual heat flow of the fin to that which would be obtained with a fin of constant temperature uniformly equal to the base surface temperature, that is, one with infinite thermal conductivity.


2. What are low finned tubes?

Low Finned tube is a finned tube obtained through plastic cold deformation. The method consists in realizing, from a smooth tube, fins with a particular geometric form without removing material; this plastic deformation causes an increment of heat exchange efficiency, and allows to reduce the heat exchanger size.


3. Where are integral low finned tubes used?

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.
