G Type Embedded Copper Fin Tube, also known as G fin tube or embedded finned tube, is an advanced heat transfer component widely used in industrial heat exchangers. It is manufactured by mechanically embedding copper fin strips into spiral grooves machined on the outer surface of the base tube.
This embedded structure creates a tight mechanical bond between the fin and the tube, significantly reducing thermal contact resistance and improving overall heat transfer efficiency. Due to its excellent performance, G type fin tubes are commonly used in high-efficiency heat exchanger applications where stable operation under demanding conditions is required.
The manufacturing process of a G Type Embedded Fin Tube involves several precise steps:
The embedded depth of the fin is generally 0.35–0.5 mm, ensuring reliable contact between the copper fin and the tube wall. After processing, the tube surface must remain free from cracks, fractures, or deformation.
For copper G type fin tubes:
The combination of high thermal conductivity copper fins and a strong embedded structure makes G type fin tubes suitable for demanding heat transfer environments.
Copper has outstanding thermal conductivity, approximately 380 W/(m·K), allowing rapid heat transfer between the fin surface and the tube.
The mechanical embedding process creates close contact between the fin and base tube, minimizing thermal resistance. Its heat transfer performance is comparable to KL type fin tubes, while providing better mechanical stability.
Unlike wrapped fin tubes, the copper fins of G type fin tubes are securely embedded into the tube grooves.
This design provides:
G type embedded fin tubes can typically operate at temperatures of approximately 280°C–350°C, depending on the combination of fin and tube materials.
Compared with other fin tube types:
This makes G type fin tubes suitable for medium and high-temperature heat exchange systems.
The copper fin surface provides good resistance against atmospheric corrosion. When combined with suitable base tube materials, G type fin tubes can maintain stable performance during long-term operation.
They are especially suitable for industrial environments requiring reliable heat transfer performance and durability.
Due to the strong mechanical connection between the fin and tube, G type embedded fin tubes can withstand high-pressure operating conditions.
The maximum working pressure can reach approximately 32 MPa, depending on tube material, wall thickness, and design requirements.
