Spiral Copper Aluminum Extruded Finned Fin Tube for Heat Exchanger

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.
