Product Description


Integral finned tubes are manufactured by rolling process on plain tubes. During finning operation, the inside diameter of the plain tube is reduced and helical fins are rolled on the tube wall. Integral finned tubes are available in ferrous as well as nonferrous materials.

Low Finned Tube 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.


Fin Tube



Integral Low Finned Tube Advantages


Combination of lower fin height and more fins per meter maintains the general ratio of 1:1 fin height to fin spacing.

Doesn’t require higher tube pitch therefore, doesn’t require shell size higher than shell of bare tube Heat Exchanger.

Improved heat transfer coefficient and rate of heat transfer as compared to conventional finned tube designs.

Compact design of heat exchanger having lesser weight and size.

Improved tube life.



Finned Copper Tube




Low Finned Tube 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.
