High Frequency Welded Longitudinal Fin Tube Air Heater 

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 P…
