Introdução
Heat transfer efficiency still is and remains an indispensable aspect of modern industrial equipment. That is why engineers opted for fin tubes in order to enhance the area of heat transfer.
A G Type Fin Tube is a robust, mechanically efficient solution for numerous heat exchanger applications.
O G type fin tubes use an embedded fin structure, while the ordinary wrapped fin tube is used. This means that the fin creates a solid mechanical bond with the base tube.
Also, this structure helps to enhance the mechanical stability and thermal performances.
G type fin tube are generally used for air cooled heat exchangers, petrochemical plants, power plants & industrial cooling equipment.
We learnt of various other professionals fin tube solutions supplier and manufacturer for industrial heat transfer applications at this Banewin Thermal
We also provide hot rolled finned tube and various heat exchanger designs as per custom requirements.

What Is a G Type Fin Tube
Tube surface with a continuos spiral groove machined in, done by Manufacturers.
The machine then places the fin strip into this channel.
Then the tube opens up around the fin foot.
Hence the tube locks the fin in place mechanically.
Um típico G type fin tube consists of:
- Tubo de base
- Spiral groove
- Metal fin strip
- Embedded fin foot
The most common fin material used by the manufacturers is aluminium.
But the base tube can be constructed of other materials.
As opções mais comuns incluem:
- Aço carbono
- Aço inoxidável
- Aço-liga
- Cobre
- Ligas de níquel
Hence, the manufacturers can manufacture G type fin tubes for different mode of operations.
How G Type Fin Tubes Work
G kind fin tubes add heat transfer through an enlarged external surface.
Working medium flows through the base tube at first.
After that, heat is conducted through the wall of the tube.
The fin transfers heat from the tube to the surrounding air.
Heat exchange is better because the fin offers more surface area.
Second, embedded structures increase the contact between fin and tube.
Also, chill the thermal contact resistance, so steel fin tubes is a G type material.
Consequently, they offer effective heat transfer on the air side.
This is used in case of air cooled heat exchanger system.

Manufacturing process of G type fin tube
G type fin tubes can be produced by manufacturers using special equipment.
This will normally be part of a multi-step process.
4.1 Preparação do tubo de base
Choose the correct base tube manufacturers.
Material is a function of temperature, pressure, corrosion and mechanical requirements.
These could be carbon steel or stainless steel, among others.
Afterwards, the manufacturers clean the tube surface.
And so the tube is prepared to be machined for a groove.
4.2 Spiral Groove Machining
Then the machine cuts a spiral groove with a constant pitch.
It is important that the groove have correct dimensions.
Therefore, manufacturers carefully control:
- Groove depth
- Groove width
- Groove pitch
- Velocidade de rotação do tubo
This groove improves adherence of the fins on the side.
4.3 Fin Strip Insertion
The next step is for the machine to insert the fin strip between the groove.
Aluminum still is the most popular fin material.
The fin is being wound around the tube continuously by machine.
Hence, this results in uniform spacing and fin structure among manufacturers.
4.4 Tube Expansion
Manufacturers subsequently expand the tube after fin insertion.
This expansion process clamps the fin foot inside of the groove (a bit like a clam that sheaths its shell).
This way, the fin material forms a tight mechanical connection.
And it makes them more resistant to thermal movement.
4.5 Inspeção final
Then, the manufacturers inspect the finished tubes.
Inspection commonly covers:
- Altura da barbatana
- Passo da barbatana
- Fixação da barbatana
- Diâmetro do tubo
- Retidão do tubo
- Condição da superfície
That being said, quality inspection protects the consistency of the product.
