Product Description
Embedded Fin Tube “G Type” is made with the fin strip wounded into a machined groove and securely locked into place by back filling with base tube material. This technique ensures maximum heat transfer and a temperature of working until 450C°.
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 (pipes) (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 (pipes) (core tube) made of austenitic steel or exotic alloys.
G Finned Tube Advantages
High fin stability, excellent heat transfer, high operating temperature.

FAQ
1. What is a fin tube?
Finned tubes are the main components of heat exchangers. They are a series of tubes where fins have been added on the outside to increase the contact area with the outside fluid, to exchange heat and between the fluid inside the tube and the fluid outside the tube.
2. Where are Fine Tubes products used?
Our main markets include the aerospace, oil and gas, nuclear, power generation, chemical process and medical device industries. However we are also developing products for emerging sectors like desalination, geothermal energy, sports and the automotive industry. We are continually innovating, so if you require tubing for other applications please get in touch and we’ll be happy to discuss your requirements.
