Home > Why Use Finnd Tube >


Finned tubes are used in applications involving the transfer of heat from a hot fluid to a colder fluid through a tube wall. The rate at which such heat transfer can occur depends on three factors: (1) the temperature difference between the two fluids; (2) the heat transfer coefficient between each of the fluids and the tube wall; and (3) the surface area to which each fluid is exposed. In the case of a bare (unfinned) tubes, where the outside surface area is not significantly greater than the inside surface area, the fluid with the lowest heat transfer coefficient will dictate the overall heat transfer rate. When the heat transfer coefficient of the fluid inside the tube is several times larger than that of fluid outside the tube (for example steam inside and oil outside), the overall heat transfer rate can be greatly improved by increasing the outside surface of the tube. In mathematical terms, the product of heat transfer coefficient for the outside fluid multiplied by the outside surface area is made to more closely match the product of the inside fluid heat transfer coefficient multiplied by the inside surface area.
In many cases, one finned tube replaces six or more bare tubes at less than 1/3 the cost and 1/4 the volume.
The whole concept of finned tubes is to increase the outside surface area of the tube.
Increases the outer surface of the tube.
Maximizes heat transfer by increasing the efficiency of the process.
Reduce the number of tubes used. (4 to 8 bare tubes per one finned tube).
Reduces the cost of equipment (1 finned tube cost is cheaper than 4 to 8 bare tubes cost).
Modeled after nature, our finned tubes effectively reduce the total number of tubes required in an application. Fins remove heat from the surface of the inner tube through convection. By increasing heat transfer rates, not only is the number of tubes needed reduced but a reduction in equipment size and cost can also occur. Combined, these reductions can make a significant—and profitable—difference to your bottom line. We offer multiple fin styles, all with different specs and operative requirements. Each respective style is sturdy and resistant to mechanical stress. All can be easily cleaned with water or steam.
