Integral Low Finned Tube


Low Fin (Integral) tubing is a type of extruded tubing that consists of short low fins.The low fin tube have the advantage of adding surface area to a smooth tube while maintaining the same outside diameter. Low Fin Enhanced tubes can be used in standard shell and tube baffles and tube sheets.This method of construction is very different from cutting grooves onto the tube as is often done by people who are on the lookout for a shortcut or who don’t know any better.The uses differ, but as far as pipes with an increased outer surface area are concerned, they are all tubes with welded peripheral fins onto steel pipes, also known as high fin tubes. Low finned tubes involve the formation of fins by direct rotational processing of steel pipes, meaning there is no worry of detachment even if later bent. Moreover, they possess excellent durability and anti-vibration properties once put into operation.A Low Fin Tube is formed by passing a tube through a set of rollers that form the fins from the parent material of the tube by making it flow in the desired way.



Aluminum Fin Tubes




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.



Copper Finned Tube




Integral Low 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.
