DR extrusion finned tube, integral rolled finned tube, steel and aluminum finned tube

Integral extruding (rolling) finned tube is iron or copper, aluminum tube through composite rolling finned, has the advantages of tight bonding, small thermal resistance, good heat transfer performance, high strength, small flow loss, strong anti-corrosion performance, in the long cold and hot working conditions is not easy to deformation, long working life and so on.

The integral rolled fins are smooth without burring and easy to be cleaned. The fins are easy to condense water on the surface during wet cooling in heating and air conditioning engineering. The surfaces are anodized under drying heating and other hot intersections, with beautiful and elegant color, and can effectively prevent surface corrosion.

Aluminum rolled finned tube is made by rolling aluminum tube as a whole, no contact thermal resistance, high strength, heat resistance and mechanical vibration, good thermal expansion performance, and has considerable expansion heat exchange surface, the effect of this finned tube heat exchanger is ahead of the series or wound heat exchanger.

According to the needs of customers, processing various specifications of steel tape finned tube, steel - aluminum composite finned tube.
