Product Description ASME SB111 C70600 Heat Exchanger Fin Tube Copper-aluminum composite finned tube is a copper-aluminum composite tube that is rolled out of fins after compounding. It has the characteristics of close combination, small thermal resistance, good heat transfer performance, high strength, small flow loss and strong corrosion resistance. It is not easy to be deformed in the case of long-term cold and hot work and long working life.The 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.

It is being used in severe corrosive conditions in which service lives longer than those of other copper alloys are desired.These Copper & Copper alloy high finned tube is intergrally extexded for the maximum surface area to achieve high tube efficiency.A good finned tube can be made by the strict conditions such as copper density, grain size and hardness.The heat transfer ratio of this high finned tube is about 8~9 times higher than other plain copper tube. ?
