G-type Fin Tubes
Fin Materials:Aluminum, Copper
Tube Materials:No limits
Fin Thickness:Min: 300 µ Max: 500µ
Tube Size:12.70mm~50.8mm
Fin Size:7~11.5Fins/Inch Fin Height Max 16mmH

In this type of finned tubes, the fin is curled into a groove on the tube wall.

  • Fin Materials: Aluminum, Copper
  • Tube Materials: No limits
  • Fin Thickness: Min: 300 µ
                               Max: 500µ
  • MANUFACTURING PROCESS
    The manufacturing tool is made up of 2 non-cutting plates set at 90° to the axis of the base tube. The first plate effects a groove for metal spinning. The second directs the ribbon in the groove and sets the fin foot in the groove through pressure on the metal displaced for the groove. A similar plate made of tungsten carbure allows us to manufacture. Gfin tubes (finned tubes)with base tubes made of austenitic steel or exotic alloys.
    ADVANTAGES
    1) Thermal
    The fin/tube wall contact is constant because of the setting and makes it possible to use a wall temperature of up to 400° C.
    2) Mechanical
    The fin is set throughout its length and consequently does not unwind even when partially uprooted.
