Manufacturing process:
Pipe line——compressing or rolling——strip peeling——washing——pressure test——blast blowing——packaging.
The cold machining process of fins provides excellent mechanical resistance , fins are strong and have strong resistance to atmospheric corrosion, etc. The pressure required to extrude the fin from the copper sleeve creates an excellent “pressure bond” between the two materials.
In addition, the copper finned material completely surrounds the metal of the tube, so there is no risk of electrical corrosion at the fin root (between the tube and the fin). All of these advantages ensure the most stable performance over time of all other fin types.
Applications:
Typically extruded fins are used in corrosive atmospheric conditions, such as off-shore applications, widely applied in equipment like water cooler, air cooler, heat exchanger, boiler and burners and so on.
Maximum working temperature is 285°C.
