L-Fin Tube
Foot Finned Tubes are utilized into an heat exchanger, which does not exceed near 400 degrees, and used primarily in air-cooled applications (including large radiators and large compressor oil coolers).
L-foot tension wound finned tubes consist of thin aluminum fin strip tightly wound helically around the tube circumference. Tube materials are carbon steel, stainless stell, or brass. A foot, 1/16" wide, is first formed on one side of the fin strip (thus, the name "L-Foot"). The strip wound tightly around the tube, with the foort bearing on the tube outer suface. A typical fin spacing is 10 fins/in of tube length (can be varied). Tension in the fin strip as it is wrapped around the tube serves to hold the fin firmly in place.
