^{Longitudinal Finned Tube Product Description:}

^{Welded Longitudinal Finned Tubes are produced by resistance welding fins in the longitudinal direction along the length of the tube. The fin strip is first formed into a U-shaped channel, such that each leg of the U will form a fin. The channels are cut to the appropriate length and then oriented along the length of the tube and resistance welded in place. The channels are welded in pairs, diametrically opposed — therefore the number of fins specified must always be a multiple of four.}

^{For a given pipe or tube size, the desired heat transfer surface area per unit length of tube can be obtained by specifying the appropriate fin height and number of fins. The maximum number of fins is dependent upon the tube outside diameter — larger OD tube can accommodate a greater number of 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.}
