“L” Foot

“L” Footed Finned Tubing

L-footed fin tubing is designed to provide uniform fin spacing and prevent separation and movement under cycling conditions within the 450°F range.

The L foot provides a greater surface area for the fin to attach to the tubing, and the shoulder edge helps to interlock the fins. This design helps to improve the heat transfer performance of the tubing and prevent potential damage from cycling.

L-Footed Fin Tubing

“L” Foot or Shoulder tension construction assures uniform fin spacing, rigidly interlocked by the fin radius overlap over the exposed shoulder edge. This prevents separation and movement under cycling conditions within the 450°F range.
