Parameters and performance

1. Technical parameters:

Height of the fin:0-16mm (or outside diameter of fin φ25-φ75); 

Pitch of fins :2.0-5.0mm; 

Length of finning tube  0.3~ 18m. 

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, outside packed with steel frame plus wooden plate.
