 Product Description


The strip is tension wound into a machined groove over the base tube material. This ensures maximum heat transfer at high temperature.

Maximum Operating Temperature-450 ° C:

Application:More specifically used in Air Cooled Exchangers OR Condensers



Finned Copper Pipe



G Finned 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 carburetor allows us to manufacture G finned tubes with base tubes made of austenitic steel or exotic alloys.
