Finned tubes are generally used in applications involving the transfer of heat from one hot fluid to another colder fluid through a tube wall. In the case of a bare ( plain ) tubes, where the outside surface area is not significantly greater than the inside surface area, the fluid with the lowest heat transfer coefficient will decide the overall heat transfer rate.

The concept of finned tubes is to increase the outside surface area of the tube.
By increasing the outside surface area of the tube, the overall heat transfer rate is increased, thereby reducing the total number of tubes required for a given application. This reduces the overall equipment size and the cost of the project.

Benefits of Low Finned Tubes :

  • Offers approximately 2.75 times external surface area of parent tube.
  • Enhanced heat exchanger efficiency means less tube is required to accomplish the same heat transfer as a    parent (plain) tube.
  • Low finned tube can increase the performance of an existing exchanger without any additional cost of building    new shells.
  • Less space and weight can be extremely valuable in offshore production or high elevation distillation columns.
  • Low finned technology can transform large Shell & Tube Heat Exchangers into compact size of Heat    Exchangers.
