L-Foot Finned Tube
Experience high efficiency with cost-effectiveness like never before! Our L-footed finned tubing is engineered to deliver exceptional heat transfer performance, particularly at lower temperature ranges, ensuring maximum operational efficiency. Crafted with a distinctive L-shaped design, this tubing maintains fin rigidity under the most demanding conditions, resisting heat cycling and high-speed air vibrations with unmatched stability.
Our L-Foot Finned Tube is versatile and can be customized in the following fin variations for tailored applications:
Knurled Fin - This fin type features an interference fit, achieved through meticulous mechanical knurling of the fin material, ensuring a snug connection with the tube wall.
LL Fin - The Double Overlap fin, or Double LL, provides a robust double strip thickness coverage, offering full protection of the base tube.
Perforated L Fin - This innovative design integrates 'tear drop' slits along the helix, effectively disrupting airflow for enhanced performance.
L-Foot Fin / Wrap-On Fin
L-Foot Tension Wound Finned Tubes Also known as Wrap-On Finned Tubes, these are ideal for scenarios where temperatures stay below approximately 300 degrees Fahrenheit, offering reliable performance in low-temperature applications requiring added tube wall protection. Constructed with a thin aluminum fin strip helically wound around the tube, our L-Foot tension wound finned tubes exemplify superior engineering. A precise 'foot' is crafted on one side of the fin strip, lending the tube its iconic name—L-Foot. This strip is expertly wound around the tube, ensuring the foot maintains comprehensive contact with the tube's outer surface. The horizontal limb of the L securely envelops the base-tube surface, ensuring optimal coverage and contact. As tension wraps the fin strip around the tube, the fin foot is firmly seated, securing the fin in its intended position. L-footed finned tubing stands out for its high-efficiency heat transfer capabilities, even at reduced temperatures. The innovative L-shaped structure guarantees fin rigidity against both heat cycles and high-speed air vibrations, enhancing durability and performance. Designed to provide a degree of atmospheric protection, this fin reduces the risk of tube wall corrosion, ensuring longevity. The extensive contact surface between the tube and the fins significantly boosts heat transfer efficiency, maximizing thermal performance. This fin configuration remains an economical yet highly efficient choice for diverse applications.
To prevent unraveling and maintain secure contact, the fin ends are meticulously stapled, preserving optimal heat exchange between the tube and ambient air. This critical contact is paramount for the air cooler's functionality, facilitating seamless heat transfer from the tube wall, through the fin, to the surrounding air.
Advantages:
Perfectly suited for low-temperature applications, ensuring reliable performance.
This type of finning is the most cost-efficient method available, offering substantial savings.
Fins that fail during production can be easily removed, allowing the reuse of the bare tube for additional finning, enhancing sustainability.
There's no necessity to create a helical groove over the core tube, simplifying the process.
Fins can be placed on ultra-thin-walled tubes, a particularly desirable feature when employing expensive alloys for the core tube, optimizing material use.
The tube is capable of withstanding temperatures up to 130°C, minimizing risks of atmospheric corrosion or thermal stress, ensuring robust performance.
Application:
Ideal for oil and gas refineries, meeting the rigorous demands of the industry.
Widely used in the petroleum, chemical, and petrochemical sectors for its superior heat transfer properties.
Crucial in natural gas treatment, providing reliable and efficient thermal management.
Beneficial in the steelmaking industry, supporting thermal processing needs.
Essential component in power plants, contributing to effective heat exchange systems.
An excellent choice for air conditioning systems, enhancing cooling efficiency and performance.

KL Footed Fin / Knurled L Footed Fin
The renowned KL fin is also celebrated as the knurled L fin. This finned tube closely mirrors the Wrap-On fin, crafted meticulously using both Wrap-On and Embedded techniques for superior resilience. Fin strips are ingeniously prepared into an L shape, akin to the L type, and elegantly rolled into a taper, allowing them to curl with precision. These are expertly helically wound onto the tube in a seamless, continuous loop under precise tension. The tube is securely embraced by the fin. A sophisticated spinning tool knurls the base tube, embedding the foot of the fin into this knurling, crafting a robust bond and unparalleled thermal efficiency.
When the optimal fin strip is utilized, the foot of each fin seamlessly aligns with the next, ensuring no gaps between fins. This effectively safeguards the tube against corrosion. Much like L fins, each fin is securely fastened at both ends to prevent unwinding. KL-Foot tension wound finned tubes are predominantly chosen for metal applications, thanks to their exceptional performance. Stunning performance up to 320°C (608°F) maximum operating temperature
Benefits:
Corrosion-resistant Tubes
Remarkable vibration resistance
Endures temperatures up to 320°C (608°F) effortlessly.
A unique blend of high thermal efficiency and stress resistance, coupled with unparalleled air corrosion protection.
KL fin tubes are a versatile replacement for any finned tube variety.
LL-Foot Fin / Overlapped L
Crafted from strips similar to L type, the LL-Foot fin features a meticulously controlled stepped double L shape, rolled into a taper for graceful curling. The LL-Foot Fin - Overlapped L is then expertly helically coiled onto a tube under meticulous tension. One fin elegantly overhangs the foot of the next, providing complete corrosion protection as the fin clings intimately to the tube. This ensures the tube remains impeccably shielded from corrosion. Often utilized in corrosive environments, this tube is a cost-effective alternative to the pricier extruded type fin.
Fins are securely fastened at each end in a manner akin to L fins. The LL-type fin tube excels at withstanding temperatures up to 350 degrees Fahrenheit (177°C).
