Copper Embedded Integral Low Fin Tube Products

Integral Low Finned Tube 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 Exchanger. 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.

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.

Integral Low Finned Tube(Copper 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.

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.
