L-Foot Finned Tube
L-footed finned tubing is a marvel of engineering, offering a highly efficient yet cost-effective solution that ensures maximum heat transfer even at lower temperatures. The ingenious L-shaped design steadfastly holds fins, providing resilience against heat cycling and high-velocity air vibrations.
The versatile L-Foot Finned Tube is available in a variety of fin designs to meet diverse operational needs:
Knurled Fin - Experience enhanced performance with this interference fit type fin, featuring expertly knurled fin material tightly bonded to the tube wall surface.
LL Fin - Discover superior coverage with the Double Overlap fin, offering double strip thickness coverage of the entire base tube.
Perforated L Fin - Unleash the power of airflow enhancement through strategically placed 'tear drop' slits around the helix on the fin face.
L-Foot Fin / Wrap-On Fin
L-Foot Tension Wound Finned Tubes also known as Wrap-On Finned Tubes, are expertly designed for applications where temperatures remain below 300 degrees Fahrenheit, protecting the tube wall while ensuring robust functionality in low-temperature settings. L-Foot tension wound finned tubes feature a thin aluminium fin strip meticulously wound helically around the tube circumference for optimal performance. A strategically formed 'foot' on one side of the fin strip, known as the L-Foot, initiates this innovative design. This strip is wound with precision, tightly embracing the tube, with the foot securing itself firmly on the outer surface. The short horizontal limb of each L intimately contacts the base-tube surface, ensuring comprehensive coverage and protection. The tension applied to the fin strip during wrapping ensures the fin foot is powerfully seated on the tube, holding the fin securely in place. L-footed finned tubing delivers unparalleled heat transfer capabilities at lower temperatures, setting a benchmark for thermal efficiency. The ingenious L-shaped design provides unwavering rigidity to fins, effectively withstanding heat cycling and high-velocity air vibrations. This fin design not only excels in performance but also offers a commendable degree of atmospheric protection against corrosion for the tube wall. Enhance your system's performance with the broad contact surface between the tube and the finning, designed to maximize heat transfer. This fin design stands out for its remarkable efficiency, paired with cost-effectiveness, offering exceptional value for your investment.
The fin ends are expertly stapled to ensure the aluminium fin remains in place, safeguarding the vital contact between the fin foot and the tube. This remarkable contact plays a pivotal role in the efficient operation of air cooler systems. It facilitates the seamless transfer of heat from the durable tube wall, through the finely crafted fin, and into the ambient air, ensuring optimal performance and enhanced cooling efficiency.
Advantages:
Perfectly engineered for low-temperature applications, offering unparalleled performance in cooler environments.
This finning technique stands out as the most economically efficient solution when compared to other available methods.
The innovative design allows for easy removal of failed fins during production, enabling the reuse of the bare tube for finning, thus reducing waste and enhancing sustainability.
Eliminates the need for creating a helical groove on the core tube, simplifying the manufacturing process and reducing costs.
This advanced finning method allows for the placement of fins on an ultra-thin-walled tube, making it especially advantageous when utilizing expensive alloy core tubes.
Engineered to withstand temperatures soaring up to 130°C while safeguarding against atmospheric corrosion and thermal stress, ensuring longevity and reliability.
Application:
Widely utilized in oil and gas refineries, ensuring efficient heat exchange and operational excellence.
Ideal for the petroleum, chemical, and petrochemical industries, providing robust solutions for intricate cooling needs.
Exceptional in natural gas treatment processes, offering reliable thermal management.
A staple in the steel-making industry, enhancing the productivity and efficiency of operations.
Essential for power plants, contributing to improved energy efficiency and system resilience.
Crucial in air conditioning systems, delivering consistent cooling and energy savings.
Highly effective in compressor coolers, ensuring optimal thermal regulation and performance.
KL Footed Fin / Knurled L Footed Fin
The renowned KL fin - also referred to as the knurled L fin - combines precision and performance in one seamless design. This finned tube mirrors the esteemed Wrap-On fin and is crafted using an expert blend of both Wrap-On and Embedded techniques, ensuring superior heat transfer and durability. Crafted from strips meticulously shaped into an L form, these fins resemble the classic L type and are then skillfully rolled into a taper, coaxing them to curl elegantly. The fin is then helically wound onto the tube in a continuous, tensioned loop, ensuring a secure and efficient attachment. The tube is gracefully embraced by the fin, enhancing strength and heat exchange. A sophisticated spinning tool knurls the base tube, seamlessly integrating the fin's foot into the knurling, resulting in a robust bond and enhanced thermal performance.
With the correct fin strip, the foot of one fin meets the next perfectly, leaving no gaps, providing continuous protection. This precise design offers exceptional protection against corrosion, ensuring longevity. Similar to L fins, these fins are carefully secured at each end to prevent unwinding, maintaining structural integrity. In metal applications, KL-Foot tension-wound finned tubes are the go-to choice, offering robust and reliable performance. Handles a remarkable maximum operating temperature of up to 320°C (608°F), catering to demanding applications.
Advantages:
Expertly crafted corrosion-resistant tubes, offering unparalleled durability and performance.
Designed to withstand vibrations, enhancing reliability and longevity.
Capable of enduring extreme temperatures up to 320°C (608°F), ensuring versatile application.
High thermal performance and stress resistance, coupled with exceptional air corrosion protection, deliver an unrivaled combination of attributes.
KL fins are versatile and can seamlessly replace any form of finned tube, enhancing adaptability.
LL-Foot Fin / Overlapped L
Meticulously crafted from strips, this fin design mirrors the L type, with the foot shaped into a precise double L, rolled into an elegant taper. The LL-Foot Fin - Overlapped L is expertly helically coiled onto a tube under tension, ensuring a secure fit and optimal performance. With each fin overhanging the next, the tube is completely enveloped, offering comprehensive protection. As a result, the tube boasts exceptional corrosion protection, making it a reliable choice. Ideal for corrosive environments, this form of tubing is a cost-effective alternative to more expensive extruded fin types.
The innovative design ensures that the fins are meticulously secured at each end, akin to the steadfast method employed in L fins, guaranteeing unwavering performance and efficiency. The robust and reliable LL-type fin tube is expertly engineered to withstand high-temperature environments, comfortably tolerating temperatures up to a remarkable 350 degrees Fahrenheit (177C), making it an ideal choice for demanding applications.
