Lord Fin Tube-Aluminum L-Foot Finned Tubes

What is L-Foot Finned Tube?

L-Foot Finned Tube is highly heat transfer efficient and cost effective,L-footed finned tubing offers maximum heat transfer at lower temperatures. The unique L-shaped design holds fins rigidly to withstand heat cycling and high velocity air vibration. The L-Foot Finned Tube can also be offered in following variations to the Fin: Knurled Fin, Double Overlap Fin, Perforated Fin tube.

Aluminum L-Foot Finned Tubes consist of thin aluminum fin strip tightly wound helically around the tube circumference. 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.

Aluminum L-Foot Finned Tube configurations:

Tube OD 5/8”, 3/4”, 1”, 1-1/4” and 1-1/2″

Fin Height 3/8″, 7/16”, 1/2” and 5/8″

Fin Type Solid or Perforated

Fin Thickness 0.014” to 0.016″

Number of fins 8 to 12 fin per inch

Fin Material Aluminum 1100-0 or Aluminum 5005

Tube Material Generally carbon steel, stainless steel, or brass — can be any material

Tube Length No practical limit

L type fin tubes, which aluminum fin strip or the copper fin strip is folded into an L shape and spirally wound tightly under the action of tension on the outer surface of the base tube. Tension in the fin strip is wrapped around the tube serves to make the fin foot forcefully on the tube, thus hold the fin firmly in place.

L-Foot Finned Tube is combined with two different materials

Core Tube: Carbon steel, stainless steel, copper

Fins: Aluminum, copper, steel

L-Foot Finned Tube Features:

1. Adopting winding process, high production efficiency

2. Uniform fin pitch, good heat transfer performance

3. Core tube is protected from air corrosion by base of fin

Maximum Working Temperature: 230°C

L-Foot Finned Tube Application:

1. Air cooler in petrochemical, power plant, paper-making, tobacco and building heating.

2. Air heater in food processing equipment

3. Air heater in plant protein and starch spay drying system
