Wrapped L Foot Tension Tube

Wrapped L Foot Tension Tube

An L-shaped foot, 1/16″ wide, is first formed on one side of the fin strip (hence the name L-Foot). The strip is then wound tightly around the tube, with the foot bearing on the tube outer surface. A typical fin spacing is 10 fins per inch of tube length — this can be varied. Tension in the fin strip as it is wrapped around the tube serves to seat the fin foot forcefully on the tube, and to hold the fin firmly in place.

L Finned Tube is combined with two different materials

Core Tube: Carbon steel, stainless steel, copper

Fins: Aluminum, copper, steel
