Production of fin heating tube
Longitudinal Finned Tube produces by high frequency resistance welding fins in the longitudinal direction with the length of the tubes. Fin strip
material shall be compatible with and suitable for standard frequency resistance welding to the specified tube material. Before applying the fins,
the tube outside surface shall be properly prepared to ensure that the fin-to-tube weld is sound. The fin strip is first bend into U-shaped
channel, so that each leg of the U will be a fin. The channels cut into the suitable length and oriented along the length of the tubes and resistance
welded in place. The channels weld in pairs, diametrically opposed -- therefore the number of fins specified always be a multiple.
For a given pipe or tube size, the desired heat transfer surface area per unit length of tubes can be obtained by specifying the appropriate fin height
and/or number of fins. The maximum number of fins depend upon the tube OD - larger OD tube can accommodate more number of fins.
The operation of "cut and twisted" longitudinal finned tubes consists of cutting through the fin channels circumferentially at specified intervals
along the tube length. The fins are then bent (or "twisted") on one side of each cut, creating a discontinuity that promotes turbulent fluid flow,
thereby enhancing heat transfer efficiency.
Application of fin heating tube
The choice of longitudinal finned tubes VS helical finned tubes seems to be governed mainly by geometric considerations. For example, some
heater configurations consist of finned tubes inserted inside other tubes, longitudinal finned tubes are the obvious choice for such applications.
In other cases, users prefer longitudinal finned tubes for installations where the tube will be oriented in a vertical direction -- the fin
orientation facilitates fluid drainage on the fin side of the tube.
Like welded helical finned tubes, this welded steel configuration can be used for practically any heat transfer application, and is particularly suited
to high temperature, high pressure applications. The important features of this configuration are efficient, effective bond of fin to tube under all
conditions of temperature and pressure, and ability to withstand high fin-side temperatures.
Advantages of fin heating tube
Provide 8 to 12 times the heat transfer area of bare tubes.
Are more efficient than bare tubes.
Provide smaller exchangers due to increased Heat Transfer area.
Often provide a more economical selection.
Fins can be "Cut & Twist" to increase shell side fluid turbulence and improve heat transfer.
