The versatile L-Foot Finned Tube can be customized with the following fin variations:
Knurled Fin - This interference fit fin is expertly knurled to enhance mechanical bonding with the tube wall surface, optimizing heat transfer.
LL Fin - Featuring double overlap (Double LL), this design provides robust double strip thickness coverage for comprehensive base-tube protection.
Perforated L Fin - By creating 'tear drop' slits around the helix, this enhancement disrupts airflow, improving heat exchange efficiency.
L-Foot Fin / Wrap-On Fin
L-Foot Tension Wound Finned Tubes also recognized as Wrap-On Finned Tubes, are ideal for applications with temperatures not exceeding 300 degrees Fahrenheit, providing necessary tube wall protection in low-temperature settings. Our L-Foot tension wound finned tubes feature a thin aluminium fin strip wound tightly in a helical pattern around the tube circumference, ensuring comprehensive surface coverage. A secure 'foot' is initially formed on one side of the fin strip, hence the name L-Foot, to maximize contact and stability. The strip is wound tightly around the tube, with the foot firmly nestled on the tube's outer surface to ensure unfaltering attachment. The short horizontal limb of each L ensures complete contact with the base-tube surface, providing full coverage and protection. As the fin strip is wound around the tube, the tension generated holds the fin foot securely, preventing displacement and ensuring stability. Our L-footed finned tubing offers unparalleled maximum heat transfer efficiency at lower temperatures, making it an ideal choice for various applications. The unique L-shaped design of our fins maintains rigidity, effectively withstanding heat cycling and high-velocity air vibrations without compromise. This superior fin design offers a degree of atmospheric protection to the tube wall, safeguarding against potential corrosion. The extensive contact surface between the tube and the finning significantly enhances heat transfer, ensuring peak performance. Our L-Foot fin design is celebrated for its high efficiency and cost-effectiveness, delivering exceptional value in various applications.
The ends of the fins are stapled with precision to prevent the aluminium fin from unraveling, maintaining the vital contact between the fin foot and the tube. This indispensable contact ensures the efficient operation of the air cooler. Heat seamlessly transitions from the robust tube wall, through the meticulously crafted fin, to the ambient air, ensuring optimal cooling performance.

KL Footed Fin / Knurled L Footed Fin
The KL fin is also referred to as the knurled L fin, recognized for its remarkable manufacturing technique and design. This finned tube mirrors the Wrap-On fin, crafted using a harmonious blend of Wrap-On and Embedded techniques for superior functionality. Fins are artistically shaped from strips into an L form, akin to the L type, then expertly rolled into a taper for a sophisticated curl. Under controlled tension, it is helically wound onto the tube in a continuous loop, ensuring a secure fit. The tube is tightly embraced by the fin, enhancing its thermal efficiency and structural integrity. A precision spinning tool knurls the base tube, integrating the fin's foot into the knurling of the tube, forging a powerful bond and elevating thermal performance.
When the correct fin strip is employed, the foot of one fin seamlessly aligns with the next, eliminating gaps and ensuring consistent protection. This meticulous design not only enhances thermal efficiency but also offers exceptional protection against corrosion. Similar to L fins, the ends are firmly attached, preventing unwinding and maintaining structural integrity. KL-Foot tension wound finned tubes are a preferred choice in metal applications, renowned for their reliability and efficiency. Boasting a maximum operational temperature of up to 320°C (608°F), it is engineered for high-temperature environments.
Advantages:
Engineered to resist corrosion, these tubes offer durability and longevity in challenging environments.
Designed to endure vibrations, ensuring stable and reliable performance under dynamic conditions.
Capable of withstanding high temperatures of up to 320°C (608°F), ideal for demanding industrial applications.
Combining high thermal performance and stress resistance with robust protection from air corrosion, this product delivers a uniquely powerful performance.
Versatile and adaptable, KL finned tubes can replace any form of finned tube, providing unmatched flexibility in various applications.
LL-Foot Fin / Overlapped L
Expertly crafted from strips similar to the L type, the foot is intricately prepared into a double L shape, rolled into a taper for optimal curl and fit. The LL-Foot Fin, or Overlapped L, is meticulously helically coiled onto a tube under precise tension, ensuring a secure and effective fit. Each fin securely embraces the tube, with one fin delicately overhanging the foot of the next, ensuring the base tube is fully shielded. This ingenious design offers exceptional corrosion protection, maintaining the tube's integrity and longevity. In corrosive environments, this cost-effective alternative to extruded type fins is frequently chosen for its superior performance and protection.
The fins are expertly secured at each end, following the same meticulous process used for L fins, to ensure unparalleled performance and reliability. Our LL-type fin tube is engineered to perfection, making it ideal for operational environments with temperatures soaring up to an impressive 350 degrees Fahrenheit (177°C).
