Longitudinal Finned Tube Product Description:
Longitudinal finned tubes are produced by welding the fins with resistance along the length of the tube. The fins first form a u-shaped channel, allowing each of the u-shaped legs to form a fin. The channel is cut to the appropriate length and then welded into place along the length of the tube and resistance. The channels are a pair of welded, polar opposites, so the number of fins specified must be a multiple of four.
For a given tube or tube size, the desired heat transfer surface area per tube unit length can be obtained by specifying the appropriate fin height and number of fins. The maximum number of fins depends on the outer diameter of the tube - the larger OD tube can accommodate more fins.
Longitudinal Fin Tube Manufacturing Process:
The longitudinal fin tubes are welded onto the core plain tubes by resistance welding or welding with filler metal.
Longitudinal Fin Tube(Carbon Steel Welded Pipe) Advantages:
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.
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：
We supply longitudinal finned tubes for:
double pipe heat exchangers
multi-tube heat exchangers
fire rated heaters
gas coolers
tank heaters
And we are able to accommodate the requirements of various industries, including oil, power, chemical, and petrochemical.
