Description
| Extruded Single Metal Fin Tube |
| Extruded single metal fin tube is made of single metal, such as aluminum fin tube or copper fin tube, stainless steel fin tube and so on. This kind of fin tube has no contact heat resistance,high strength,heat shock resistance and mechanical vibration resistance, good thermal expansion performance, and has a considerable extended heat transfer surface. |
| 1. Copper Fin Tube |
| Copper finned tube is a heat transfer element. In order to improve the heat transfer efficiency, usually add fins to the surface of the heat exchange tube to increase the surface area ( or internal surface area ) of the heat exchang tube, so as to achieve the purpose of improving the heat transfer efficiency. The overall fin tube has no contact thermal resistance, it has good heat transfer performance, high strength, thermal vibration and mechanical vibration resistance, good thermal expansion performance. Whole rolled fin is smooth without burr, no wrinkle, easy to clean, in the heat exchange heating and other occasions not easy to dust, fouling. |
| 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 atmospheric corrosion resistance, etc.The pressure required to extrude fin from the copper sleeve creates an excellent “pressure bond” between the two materials. Application Typically extruded fins are uesd in corrosive atmospheric conditions, such as off-shore allpications, widely applied in equipment like water cooler, air cooler, heat exchenger, boiler and burners and so on. |
| 2. Aluminum Fin Tube |
| Typically extruded fins are uesd in corrosive atmospheric conditions,such as off-shore allpications, it also widely applied in equipment like water cooler, air cooler,heat exchenger,boiler and burners and so on. Single metal composite fin tube is made of aluminum tube by the whole rolling, called aluminum rolled fin tube, no contact termal resistance, high strength, heat resistance and mechanical vibration, thermal expansion performance is good, and has a considerable expansion of heat transfer surface. Whole rolled fin is smooth without burr, no wrinkle, easy to clean, in the heating and air conditioning engineering wet cooling is easy to remove the condensation on the outside surface of the fin, in the heat exchange heating and other occasions not easy to dust, fouling. |

Product Description
With an aim to increase the heat exchanging efficiency, It’s usually to extend the surface area (or internal surface area) by adding fins onto a tube, which, through this manufacturing process, would greatly improve and upgrade the heat transferring efficiency of heating tube, it’s called Finned Tube or Fin Tubes.
But, as a element of heat exchanger, fin tubes would be working on very high temperature condition for long time. For example, the application of boilers, which is with bad ambience, high temperature, high pressure and corrossion, all require the fin tubes to be qualified with very high performance capacity as following:
1. Anti-corrossion
2. Anti-wear
3. Lower contact resistance
4. Higher stability
5. Anti-fouling ability
