Finned Tube

Extruded Fin Tube:
This fin type is formed from a bi-metallic tube consisting of an aluminium outer tube and an inner tube of almost any material. The fin is formed by rolling material from the outside of the exterior tube to give an integral fin with excellent heat transfer properties and longevity. Extruded fin offers excellent corrosion protection of the base tube.Maximum working temperature: 545®F（285®C）Fin Materials: Aluminium

L FIN TUBE:
The strip material is subjected to controlled deformation under tension giving the optimum contact pressure of the foot of the fin onto the base tube thus maximising the heat transfer properties. The foot of the fin considerably enhances the corrosion protection of the base tube.
Maximum Working Temperature: 150℃
Atmospheric Corrosion Resistance: Acceptable
Mechnical Resistance: Poor
Fin Materials: Aluminum, Copper
Tube Materials: No limits.

G FIN(EMBEDDED FIN)
(Embedded Fin)The fin strip is wound into a machined groove and securely locked into place by back filling with base tube material. This ensures that maximum heat transfer is maintained at high tube metal temperatures.
Maximum Working Temperature: 450℃
Atmospheric Corrosion Resistance: Poor
Mechnical Resistance: Acceptable
Fin Materials: Aluminum, Copper, Carbon Steel
Tube Materials:No limits
