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

 

 

Aluminum Finned Tube

 

 

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.

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.

 

3. What is 'G' Fin Tube or Embedded Fin Tube?

As the name suggests, the embedded fin tube or G fin tube is an extended surface fin tube where the fins are externally applied on the base tubes. A groove is formed continuously on the base tube and the fin edge is inserted in the groove. After the fin is inserted in the groove a set of rollers is used to back fill the groove and the fin is then securely embedded in the base tube.

The strength of the Embedding or more commonly known as Fin to Tube bond test is checked by hanging a 3 Kg free wight to an Isolated fin. This ensures whether the fin has been Embedded into the base tube properly.

 

4. 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. Where are 'G' Fin Tubes or Embedded Fin Tubes used?

'G' Fin Tubes or Embedded Fin Tubes are mainly used in air fin coolers and many different types of air-cooled radiators. These types of 'G' Fin Tubes mainly find application in areas where the temperature for heat transfer is in a slightly higher range. The Embedded Fin Tubes are mainly used in places with higher temperature and where the working atmosphere is relatively less corrosive to the base tube.

Main industries in which the 'G' Fin Tubes find service are Process Chemical Plants, Refineries, Gas Processing Plants, Steel Plants, Power Plants, Fertilizer Manufacturing Plants, etc.
