Extruded Finned 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 Finned 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” Embedded Finned Tube

(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.

KL Finned Tube

Manufactured exactly as the ‘L’ fin except that the base tube is knurled before application of the fin foot. After application the fin foot is knurled into the corresponding knurling on the base tube thereby enhancing the bond between the fin and tube resulting in improved heat transfer characteristics.

Maximum Working Temperature: 260℃
Atmospheric Corrosion Resistance: Acceptable
Mechnical Resistance: Acceptable
Fin Materials: Aluminum, Copper
Tube Materials: No limits.

LL Finned Tube

Manufactured in the same way as the ‘L’ fin type except that the fin foot is overlapped to completely enclose the base tube thereby giving excellent corrosion resistance. This type of tube is often used as an alternative to the more expensive extruded type fin in corrosive environments.
Maximum Working Temperature: 180℃
Atmospheric Corrosion Resistance: Acceptable
Mechnical Resistance: Poor
Fin Materials: Aluminum, Copper
Tube Materials: No  limits.
