Product Description
Fin is embedded into the outer wall of the tube, but gives no surface protection. The finned tube is used in general use for continuous process applications; ie refineries, petrochemical, fertilizer and gas plants.
Upper temperature limit: 450°C
Tube Material : Harder material (Please contact us for guidance)
Fin Material : Aluminium , Copper or steel
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 tubes (core 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 carburate allows us to manufacture. G embedded fin tubes ( fin tubes )with base tubes (core tube) made of austenitic steel or exotic alloys.
