Product Description
L-Foot Finned Tube
L type Spiral Wound Finned Tube
L type Spiral Wound Finned Tube
Highly efficient yet 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 - An interference fit type fin with mechanical knurling of the fin material to the tube wall surface.
LL Fin - Double Overlap fin(The double LL) coverage provides a double strip thickness coverage of the entire base tube.
Perforated L Fin - This enhancement of the fin face creates "tear drop" slits around the helix that break up air flow.
L-Foot Fin / Wrap-On Fin
The ends of the fins are stapled to prohibit the aluminium fin from unravelling, and loosing the contact between the fin foot and the tube. This contact is critical to the operation of the air cooler, since the heat is transferred from the tube wall, through the fin, to the surrounding ambient air.
Advantages:
Suitable for low-temperature application
The finning type is the most cost effective method compared to the others.
The failed fins can be easily removed during production and bare tube can be used again for finning.
There is no need for make a helical grove over the core tube.
It is possible to place the fins on a very thin-walled tube with is particularly desirable when using expensive alloys as core tube.
The tube can withstand a temperature of up to 130°C without the risk of atmospheric corrosion or thermal stress.
Application:
Oil and gas refineries
Petroleum, chemical and petrochemical industries
Natural gas treatment
Steel making industry
Power plants
Air conditioning
Compressor coolers
KL Footed Fin / Knurled L Footed Fin
The KL fin is also known as the knurled L fin. This finned tube is almost identical to the Wrap-On fin and is made using both Wrap-On and Embedded techniques. The fins are made from strips that have been prepared into a L shape that is comparable to the L type, then rolled into a taper that causes it to curl. It is then helically wound onto the tube in a continuous loop under tension. The tube is hugged by the fin. A spinning tool knurls the base tube, and then the foot of the fin is knurled into the knurling of the base tube, resulting in a tight bond and improved thermal performance.
The foot of one fin bumps up against the next fin if the correct fin strip is utilised, and there is no space between the fins. This helps to protect the tube from corrosion. In a similar way to L fins, the fins are attached at each end to prevent unwinding. In applications involving metal, KL -Foot tension wound finned tubes are typically employed. Up to 320°C (608°F) maximum operating temperature
Advantages:
Corrosion-resistant Tubes
Vibration resistance
It can withstand temperatures of up to 320°C (608°F).
High thermal performance and stress resistance combined with protection from air corrosion is a one-of-a-kind combo.
Any form of finned tube can be replaced with KL.
LL-Foot Fin / Overlapped L
The fins are created from strips in a similar way to the L type except that the foot is prepared into a carefully controlled stepped double L shape, rolled into a taper that allows it to curl. The LL-Foot Fin - Overlapped L is next helically coiled onto a tube under tension. The fin clings the tube, with one fin overhanging the foot of the next fin and the base tube completely covered. The tube is well protected from corrosion as a result of this. In corrosive settings, this form of tube is frequently used as an alternative to the more expensive extruded type fin.
Fins are secured at each end in the same way that L fins are. The LL-type fin tube is suitable for temperatures of up to 350 degrees Fahrenheit (177C degree).

We offers different finned tubes: tension wound finned tubes, embedded finned tubes and extruded finned tubes.
Tension wound finned tubes are formed by winding a strip made of aluminium or copper around the tube under tension. The strip winding technology provides different types of fins: L-Fin, LL-Fin, KL-Fin.
Embedded fins (G-Fins) are made by winding aluminium or copper strip into a helical groove machined on the outer surface of the tube.
Tension wound finned tubes, embedded finned tubes and extruded finned tubes are main devices for air coolers and the common application fields are:
Heat exchangers for power plants (electric, nuclear, thermal and geothermal power plants)
Steam condensate systems
Chemical and petrochemicalindustry
Food processing plants and refrigeration technology
Industrial (steel mills, incinerators, gas compression facilities)
Application
Aftercoolers, air coolers, air heaters, charge air chillers, condensers, convection heaters, electric heaters, evaporators, fluid coolers, gas coolers, heat pipes, hydrogen coolers, industrial tumble dryers, intercoolers, immersion heaters, oil coolers, radiators, refrigeration, solvent recovery and steam to air heat exchangers.
