Function:

Energy conservation, high heat transfer, long time using;

1. Technical parameters:

Height of the fin: ≤16mm (or outside diameter of fin φ25mm-φ85mm); 

Pitch of fins : ≤10mm; 

Thickness of fins: ≥0.3mm;

2. Single metal rolling finning tube : pure aluminum 1060 or aluminum alloy 6063, the 6061 material of outside diameter less than 40 mm 

3.Double metal rolling finning tube : tube-based protection from the outer layer of aluminum tubes, corrosion-resistant; tube-based can be made from carbon steel pipe ,in addition to, stainless steel tube and copper tube can also be used, as well as titanium alloy tube.

4.Package: the aluminum finned tubes are well packed in plastic.
