Copper Finned Tube

The fins can be acquired, after the outer surface of a plain tube is roll-formed. This process can help increase the strength of the finned sections, but the plain ends and lands are still soft. High-finned tubes call for those materials that can be cold-worked easily, such as aluminum and copper. Both aluminum and aluminum alloys allow up to 13mm in fin height, while the copper achieves the height of 10mm. If the finned tubes are obliged to fit themselves for bending and coiling, they will go through soft annealing process necessarily.

We adopt pipe mill to create the successive screw fins upon seamless pipe, so as to make our highly efficient heat exchange pipe. The product, including both the pipe body and fins, is made of single metal material, so it does not have the contact electrical resistance, but have the good heat conductivity, high mechanical strength, remarkable vibration resistance and heat swelling property. It is widely applied in the petrochemical industry, metallurgy power generation and food process fields, as well as the ship and central air conditioning system.

Our company mainly chooses the pure copper or copper alloy to make the high efficient heat exchanging pipe. For the purpose of enhancing the heat conductivity of the copper finned tube further, we already developed the straight type with 8mm high fins and the coiled type which has the minimum bending diameter of 15mm.
