Product Description

 

 

The ‘G’Fin Tube is also known as Embedded Fin Tube. This type of fin tube widely finds acceptance where the requirement is for higher operating temperature and relatively lower corrosive atmosphere

The fins are manufactured by embedding the fin strip into a groove formed on the base tube. The Fin is allowed to be placed in the groove and then the back filling of the groove is carried out to ensure firm adherence of the fins to the base tubes. Because of the process this type of Fin Tube is also known as ‘G’ Fin tube or Grooved Fin Tube.

The grooving, fin stack inserting and the back filling processes are carried put simultaneously as continuous operation. Because of the back filling procedure the bond between the Fin material and the Base tube is one of the best. This ensures optimum Heat Transfer.

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.

G Finned Tube Advantages 

 

High fin stability, excellent heat transfer, high operating temperature.

The fin/tube wall contact is constant because of the setting and makes it possible to use a wall temperature of up to 450°C.

The fin is set throughout its length and consequently does not unwind even when partially uprooted.

This kind of finned tube is one of optimum choices for having good effectiveness/cost ratio.

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.

 

3. What is an 'G' Fin Tube made of?

'G' Fin Tubes or Embedded Fin Tubes are made of two main components, Base Tube and Fin Strip material.We can supply the 'G' Fin Tubes in the following combinations of Base Tube and Fin Material:

Base Tube Material: Carbon Steel, Alloy Steel, Mild Steel, Stainless steel and tubes manufactured by ERW or Seamless Process

Fin Material: Aluminum, Copper.

 

5. How do you ensure a quality product?

We always put quality as the most important thing for customers, and we control the quality from raw material inspection, production checking to water pressure test and strength test. Also the third party can be authorized to check.
