What is Stainless Steel Fin Tube?

The Fin Tubes are used in applications wherein heat transfer occurs from a hot fluid to a cold one through a tube wall. They come with their fins which help to increase the surface area against which the outer fluid would come in contact. The Stainless Steel Fin Tubes are used with shell and tube heat exchangers to enhance the heat transfer process between the inside and outside of the tube. The Extruded Fin Tube manufacturer In India produces fin tubes for a wide range of applications like coils for hybrid cooling towers, the chemical industry, surface coating productions, and so on.

Difference between Low Fin Tube & High Finned Tubes

The Low Fin Tubes has rotational processing of the steel tube’s outer surface to create a fin shape. It is essentially a single integral tube made of a single piece of material. They have a smaller fin, about 1/16th of an inch of the fin height. The Low Fin Tubes For Heat Exchangers are generally used in liquid to gas or liquid to liquid applications like chillers, condensers, etc.

The use of High Finned Tubes helps to attain a large surface area to optimize the heat transfer between the fluid and the tubes wall. They have exceptional temperature control efficiency in different types of environments. Available in customizable sizes, the tubes are used in industries like power generation, chemical processing and HVAC systems.
