Types of Finned Tubes

‘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 maximizing the heat transfer properties. The foot of the fin considerably enhances the corrosion protection of the base tube. Max. operating. temp. 150ºC.

‘LL’ Finned Tubes

Manufactured in the same way as the 'L' finned tubetype except that the fin foot is overlapped to completely enclose the base tube thereby giving excellent corrosion resistance. This type of finned tube is often used as an alternative to the more expensive extruded type fin in corrosive environments.

‘KL’ Finned Tubes

Manufactured exactly as the 'KL' Finned Tube 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.

‘G’ Embedded Finned Tubes

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.

Extruded Finned Tubes

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 Transferproperties and longevity. Extruded Fin offers excellent corrosion protection of the base tube.
