Finned Tube Type: G-Fin | Embedded Fin Tube

Embedded fin tubes (also known as G type finned tubes) are heat exchange elements that have spiral grooves pre-processed on steel tubes, and then the fins are mechanically embedded or welded into the grooves of the base tube to increase the heat exchange area. They are widely used in air coolers and heat exchangers.

What is G-Fin?

G type finned tube is a type of finned tube, which belongs to the embedded structure. The groove structure is formed on the surface of the base tube through mechanical processing, and then the fins of aluminum/copper/iron are embedded to enhance heat transfer. Its core features include:

Structure: The machined groove (G-type) process is used to embed fins on the outer wall of the base tube to form a high heat conduction channel ‌

Material: The base tube is mostly made of metal materials such as carbon steel and stainless steel, and the fins are often made of thermal conductive materials such as aluminum and copper ‌

Application: Suitable for industrial equipment such as air coolers, heat exchangers, and economizers, with corrosion resistance and wear resistance ‌

Finned Tube Type: G-Fin Type Subdivision

According to different processing techniques, G-type finned tubes can be divided into:

Inlaid type: The fins are embedded in the surface of the base tube through mechanical grooving, which is tightly combined and not easy to deform ‌

High-frequency welding type: Spiral finned tubes made by high-frequency welding technology are suitable for high temperature and high pressure environments.

Finned Tube Type: G-Fin Performance characteristics

‌High heat transfer efficiency‌: Improve heat transfer efficiency by increasing surface area, and low contact thermal resistance ‌

‌Strong corrosion resistance‌: The combination of base tube and fin material can adapt to a variety of corrosive media ‌

‌Wide application‌: Covering high temperature and high pressure scenarios in petrochemical, electric power, building heating and other industries
