Our L-Footed finned tubing is a marvel of engineering, delivering exceptional heat transfer efficiency even at lower temperatures, offering a cost-effective solution without compromising on performance. The ingenious L-shaped configuration ensures the fins remain steadfast, withstanding both heat cycling and high-velocity air vibrations, promising longevity and reliability.

The L-Foot Finned Tube is available in a variety of fin designs, tailored to meet specific operational requirements:

Knurled Fin - Featuring interference fit technology, this unique fin is mechanically knurled to secure the fin material firmly to the tube wall.

LL Fin - Offering a double overlap design (The Double LL), this variant provides comprehensive double strip thickness coverage across the entire base tube.

Perforated L Fin - Enhanced with strategic 'tear drop' slits around the helix, this design expertly disrupts air flow for improved performance.

L-Foot Fin / Wrap-On Fin

L-Foot Tension Wound Finned Tubes Also recognized as Wrap-On Finned Tubes, these are ideally employed in low-temperature applications, effectively shielding the tube wall up to 300 degrees Fahrenheit. L-Foot tension wound finned tubes are meticulously crafted with a thin aluminium strip, tightly coiled around the tube’s circumference to ensure perfect contact. Each fin strip begins with a 'foot' formed on one side, hence the name L-Foot, setting a foundation of stability and efficiency. The fin strip is expertly wound around the tube, with the foot firmly contacting the tube's outer surface, ensuring complete coverage and protection. The short horizontal limb of each L is meticulously positioned to cover the base-tube surface entirely, enhancing heat transfer efficiency. The tension applied during the wrapping of the fin strip ensures the fin foot is securely seated on the tube, maintaining firm contact and stability. L-Footed finned tubing delivers outstanding heat transfer capabilities at reduced temperatures, optimizing performance without excess cost. The unique L-shaped design guarantees robust fin rigidity, capable of withstanding heat cycling and high-velocity air vibrations, ensuring consistent performance. This fin design provides substantial atmospheric protection to the tube wall, guarding against corrosion and extending the product's lifespan. The extensive contact surface between the tube and the fin enhances heat transfer, ensuring maximum efficiency and reliability. This finned tube design is not only highly efficient but also cost-effective, making it an ideal choice for various industrial applications.

The ends of the fins are expertly stapled, preventing any unraveling of the aluminium fin and ensuring permanent contact between the fin foot and the tube. This connection is pivotal to the seamless functionality of the air cooler, as it facilitates the transfer of heat from the tube wall, traversing the fin, and reaching the ambient air, thereby optimizing thermal efficiency.

Advantages:

Ideal for low-temperature applications, ensuring superior performance even in conditions demanding minimal temperatures.

This particular finning type emerges as the most economically viable option, outperforming other methods in terms of cost efficiency.

The design allows for straightforward removal of failed fins during manufacturing, enabling the reuse of the bare tube for subsequent finning processes.

The innovative design eliminates the necessity to create a helical groove on the core tube, simplifying the production process.

Fins can be applied to very thin-walled tubes, a feature that is especially desirable when working with costly alloy core tubes, enhancing material utilization.

The tube boasts the capability to withstand temperatures up to 130°C, with no threat from atmospheric corrosion or thermal stress, ensuring long-term durability.

Application:

Perfectly suited for oil and gas refineries.

KL Footed Fin / Knurled L Footed Fin

The KL fin is also recognized in the industry as the knurled L fin, known for its robust design and exceptional thermal management. This finned tube mirrors the Wrap-On fin in terms of design, utilizing both Wrap-On and Embedded techniques for heightened performance. Fins are crafted from strips prepared into an L shape, similar to the L type, then meticulously rolled into a taper that initiates curling. Subsequently, it is helically wound onto the tube in a seamless, continuous loop under tension, ensuring a secure fit. The fin embraces the tube, providing a snug and efficient thermal contact. A specialized spinning tool knurls the base tube, integrating the foot of the fin into the knurling, achieving a robust bond and enhanced thermal performance.

Fin placement is precise, with no gaps between fins if the correct strip is used, ensuring consistent protection from corrosion. This meticulous design significantly aids in shielding the tube from corrosive elements. Fins are securely attached at both ends, akin to L fins, to prevent unwinding, ensuring stability and longevity. KL-Foot tension wound finned tubes are predominantly utilized in metal-related applications, offering superior thermal efficiency. Supports an impressive maximum operating temperature of up to 320°C (608°F), ensuring reliability in high-temperature environments.

Advantages:

Corrosion-resistant Tubes

Exemplifies vibration resistance, maintaining structural integrity under dynamic conditions.

Engineered to endure temperatures reaching up to 320°C (608°F), suitable for demanding thermal conditions.

Boasts high thermal performance and stress resistance, coupled with protection against air corrosion, creating an unmatched combination.

KL finned tubes offer versatility, serving as a replacement for any existing finned tube configuration.

LL-Foot Fin / Overlapped L

Fins are fashioned from strips akin to the L type, with the foot crafted into a precisely controlled stepped double L shape, rolled to enable curling. The LL-Foot Fin - Overlapped L is expertly helical coiled onto the tube under tension, ensuring a secure attachment. The fin tightly clings to the tube, with each fin overhanging the subsequent fin's foot, fully covering the base tube for optimal protection. This design expertly shields the tube from potential corrosion, enhancing service life and reliability. In environments where corrosion is a concern, these remarkable tubes offer a cost-effective solution. They serve as an excellent alternative to the more pricey extruded type fins, providing robust and reliable performance without compromising on quality.

Much like the renowned L fins, these fins are meticulously secured at each end, ensuring optimal stability and performance in various applications. With an impressive resilience to heat, the LL-type fin tube is engineered to withstand temperatures soaring up to 350 degrees Fahrenheit (177 degrees Celsius), making it an ideal choice for demanding thermal environments.
