Longitudinal Finned Tube Product Description:
As with welded spiral finned tubes, this welded structure can be used for virtually any heat transfer application.
The choice between longitudinal finned tube and spiral finned tube seems to depend mainly on geometric factors. For example, some heater structures consist of finned tubes inserted into other tubes -- longitudinal finned tubes are an obvious choice for such applications. In other cases, users prefer the longitudinal finned tube installation, where the tube will be in a vertical direction - the finned direction facilitates fluid drainage on one side of the finned tube.
Longitudinal finned structures are most commonly used in shell and tube applications, such as in double-tube and multi-tube heat exchangers, where the longitudinal finned tube is telescopic in the hole of a larger tube shell. Heat is transferred between the fluid flowing through the finned tube hole and the fluid flowing through the shell hole.
The fluid flowing through the shell hole is forced to flow between the longitudinal fins. In this case, the spiral fin prevents the flow of the fluid, rather than allowing it to flow between the fins.
Longitudinal Fin Tube Manufacturing Process:
The longitudinal I/L or U fins are welded onto the base tubes by resistance welding or welding with filler metal. U-Bend tubes with LFW, Fins also possible.
Longitudinal Fin Tube(Carbon Steel Welded Pipe) Advantages:
1. Longer working life than others ordinary welding helical fin tubes.
2. Much safer and energy saving.
3. Increase the heat transfer rates for viscous liquids.
4. Perforated fin type used whenever drainage of liquid from fin channels become a problem.
5. Longitudinal fin tubes are widely used in horizontal heat exchangers.
Brown Fin Tube Properties:
Improve heat transfer efficiency in efficient space.
Reduces installation space on required heat transfer surfaces.
Reduce the cost of the equipment, and have a high operational reliability.
The pressure drop on the side of the tube is reduced and the operation cost is reduced.
The stiffness of steel tube is improved, and the seismic performance of steel tube is improved.
Enhance heat transfer, reduce flow resistance and metal consumption.
Longitudinal Finned Tube(Welded Steel Pipe) Applications：
1. Chemical-,petrochemical-,oil-,and power industry
2. Heat exchanges
3. Fired heaters
4. Gas coolers and heaters
5. Tank heaters.
