1. 19.05 Medium-High Copper Finned TubeThe 19.05 medium-high copper finned tube is commonly used to make the coiled pipe. It shows terrific mould ability, and can adapt to different working environment. A lot of heat exchange apparatuses need the product, like oil cooler and reduction gears
    1. 25.5 Medium-High Copper Finned TubeThe 25.5 medium-high copper finned tube is applicable to make all kinds of coiled pipes. We can make the product upon requests of customer. The high thermal exchange rate and good mould ability of the product are greatly valued by our German clients, and we have specially design the product for their heating system
    1. 27.5 Medium-High Copper Finned TubeThe 27.5 medium-high copper finned tube has higher heat exchange rate than the 19.05 type and 25.5 type. It has good mould ability to be made into all kinds of coiled tube. Our clients from German who applied our product onto their heating equipment gave us a high praise

Medium-High Finned Tubes

The medium-high finned tube is made from the seamless metallic pipes by overall extrusion treatment. The fin thickness ranges from 3mm to 4.5mm. It has the spiral bar or corrugation inside, thus the heat exchange rate can be pretty high. If we soften the fins by means of annealing treatment, we are able to bend or wind the product into special shapes, to make different heat exchangers.

Usage Range
Our finned tube is applicable to the following fields.
Heating industry: water heater
Machinery industry: oil cooler, air cooler.
Cooling and air conditioning industry: cold condenser, cold evaporator.
Process technology field

Material
We can offer products made of copper, copper alloy, aluminum, or aluminum alloy.
