Lord Fin Tube--ASTM A 179 L type finned tube

Why choose ASTM A 179 L type finned tube?

L-Foot finned aluminum tubes are made of a thin aluminum fin strip that is tightly wound helically around the circumference of the ASTM A179 tube. On one side of the fin strip, an L-shaped foot 1/16′′ wide is first formed (hence the name L-Foot). The strip is then tightly wound around the tube, with the foot bearing on the outer surface of the tube. Fin spacing is typically 10 fins per inch of tube length, but this can be adjusted. Tension in the fin strip as it wraps around the tube serves to forcefully seat the fin foot on the tube and hold the fin firmly in place.
