Longitudinal Finned Tube Product Description:
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.
Longitudinal Fin Tube Manufacturing Process:
The longitudinal I/L or U shape fins are welded onto the core plain tubes by resistance welding or welding with filler metal (Spot welded).
1. U bends tubes with longitudinal fins and Fin Tube Coils are available for requesting.
2. Longitudinal fins types: one-piece shape, standard U bent shape, cut & twist, perforated type etc…
3. The fin channels are welded to the tubes in opposite pairs. Fin height, number of fins and fin thickness can be specified.
4. Fins can be applied to either OD tube or NB pipe.
Longitudinal Fin Tube(Carbon Steel Welded Pipe) Advantages:
Increase of heat transfer rates for viscous liquids. Perforated fin type used whenever drainage of liquid from fin channels become a problem. 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.
