G type embedded finned tube

G-Type Embedded Finned Tube

Manufacturing‍‌‍‍‌ Process:

The outer surface of the base tube is covered with fins which are firmly fixed into it by way of mechanically machined grooves.

Thanks‍‌‍‍‌ to a very reliable mechanical bond, the embedded (G-type) finned tube can endure not only extremely high temperatures but also very severe thermal shocks.

High Operating Temperature: In general, the highest medium temperature allowed is 400℃.

Mechanical Strength: In addition, the embedded design gives the tube outstanding mechanical strength and rigidity. The fin-base tube adhesion is so strong that the pull-out force is usually at least 70N, and with advanced methods, it can even exceed 80N. This guarantees operation in vibrating environments. Also, fins have high resistance to deformation and thus, they will keep their original shape, which will ensure heat transfer efficiency.

Thermal Performance: When compared to other finned tubes, the embedded finned tube by its bonding very tightly greatly lowers the contact thermal resistance between the fin and the base tube. Thus it ensures that heat is effectively transferred from the base tube to the fin surface and then through the expanded surface area to the surrounding ‍‌‍‍‌medium.
