Description:
Overlapped L Footed Finned Tube
The choice between Aluminum L-foot and the welded finned tubes (helical and longitudinal) is usually clear -- aluminum L-foot finned tubes are generally used in air-cooled applications with service temperatures below 400 degrees F. Within the aluminum L-foot category, the choice between solid fin and perforated fin is less clear, and depends upon whether you want to take advantage of the improved heat transfer efficiency claimed for perforated fin.
1. Product brief
1.1. Manufactured in the same way as the 'L' finned tube type 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.
L Foot or Shoulder tension construction assures uniform fin spacing, rigidly interlocked by the fin radius overlap over the exposed shoulder edge.
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
Our L-foot finned tubes consist of aluminum fins formed into an L-foot configuration and wound helically around the tube while under tension. We offer both solid fin and perforated fin L-foot finned tubes.
