Longitudinal Finned Tube Product Description:
Longitudinal finned tubes are used to give a great performance in any heat transfer application, especially in petrochemical area. They are the heart of heat exchangers that use their effective characteristics.
Our finned tube is particularly efficient as the channels are welded on the external surface of the tube by means of resistance weld technique. Every channel is the result of a fin strip shaped into a U form (made by us), such that each leg of the U will form a fin. The number of fins will be always a multiple of four with a maximum number depending on the outside diameter of the tube and on the thermodynamic calculations promoted for a specific job.
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.
