Product Description


The Integral Low Fin Tubes is a tube where the external surface of the tube is enhanced by the process of finning and fins are drawn from the base material of the tube, resulting to increase in the surface area by 2.5 times than the plain tube area. The Extruded surface achieved through our manufacturing process is real and uniform.


Finned Copper 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



Integral Low Finned Tube(Copper Finned Tube) Advantages


Offers 2.5-3 times the external surface area of bare tube

Enhanced heat exchanger efficiency means less tube is required to accomplish the same heat transfer as a bare tube

Low finned tube can increase the performance of an existing exchanger without the difficult and expensive task of building new shells etc

Reduced space and weight can be extremely valuable in offshore production or high elevation distillation columns. Low finned technology can transform large shell and tube exchangers into compact heat exchangers


Low Finned Tube


Low Finned Tube Properties


Low maintenance

Persistent against rust

Light weight


Aluminum Fin Tubes



Integral Low fin tube  Applications


Low finned tube is mainly used in air conditioning and refrigeration equipment in the condenser and evaporator absorption refrigeration oil cooler and other all kinds of heat exchanger,heat exchanger used in thermal power plants and nuclear power plants and evaporator, Marine switch in the condenser and evaporator used in gas turbine units and air cooler used for diesel

oil industry secondary cooler and cooler waste heat recovery system in various dryer and heater used in the heat exchanger in chemical industry.
