G Type Embedded Finned Tube

G Fin Tube discription: The fin strip is wound into a mechanically produced groove and tightened by backfilling of the base material under pressure.

Groove depth appr. 0,4 mm.

G Fin Tube advantages: High fin stability, excellent heat transfer, high operating temperature.

G Type Fin Tube 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 G finned tubes with base tubes made of austenitic steel or exotic alloys.
