L-Foot Finned Tube
Crafted with precision and efficiency, the L-footed finned tubing is an innovation designed to deliver unparalleled heat transfer at reduced temperatures, making it both a highly efficient and cost-effective solution. Boasting a unique and sophisticated L-shaped design, these fins are expertly secured to withstand the challenges of repeated heat cycles and high-velocity air vibrations, ensuring maximum performance and durability.
The L-Foot Finned Tube offers diverse fin variations to meet your specific needs:
Knurled Fin - This variant features an interference fit, enhanced through the mechanical knurling of the fin material onto the tube wall surface.
LL Fin - Known for its double overlap design, this double LL variation provides comprehensive double strip thickness coverage across the entire base tube, ensuring superior performance.
Perforated L Fin - This innovative enhancement introduces 'tear drop' slits around the helix, effectively disrupting air flow for improved efficiency.
L-Foot Fin / Wrap-On Fin
L-Foot Tension Wound Finned Tubes Also referred to as Wrap-On Finned Tubes, these are ideal for low-temperature applications, withstanding up to 300 degrees Fahrenheit, and offering essential tube wall protection. Characterized by its construction, the L-Foot tension wound finned tubes feature a thin aluminum fin strip meticulously wound helically around the tube's circumference. The 'foot' is ingeniously formed on one side of the fin strip, lending the name L-Foot its origin. The strip is then expertly wound with precision, ensuring the foot bears securely on the tube's outer surface. Each L's short horizontal limb is in full contact with the base-tube surface, providing complete coverage for optimal performance. As the fin strip is carefully wrapped, tension ensures the fin foot is seated with precision, holding the fin firmly in place. L-footed finned tubing is optimized for maximum heat transfer, especially at lower temperatures, making it a go-to solution. The innovative L-shaped design not only holds the fins with rigidity but also combats heat cycling and high-velocity air vibrations, ensuring consistent reliability. This fin design affords a protective barrier against atmospheric corrosion for the tube wall. The expansive contact surface between the tube and finning magnifies heat transfer efficiency. This design is not only profoundly efficient but also remarkably cost-effective.
To prevent unraveling and maintain crucial contact between the fin foot and tube, the fin ends are securely stapled. This vital contact is essential for air cooler operation, as heat is methodically transferred from the tube wall, through the fin, into the ambient air.
Advantages:
Perfectly suited for low-temperature applications, offering reliable performance.
This finning type is the most cost-effective method available when compared to other options.
Easily remove failed fins during production and repurpose the bare tube for finning, reducing waste.
Eliminates the need to create a helical groove on the core tube, simplifying the process.
Allows for fin placement on a very thin-walled tube, ideal for costly alloys as a core tube, enhancing economic feasibility.
Capable of withstanding up to 130°C without the risk of atmospheric corrosion or thermal stress, ensuring longevity.
Application:
Oil and gas refineries, providing essential solutions for energy sectors.
Widely applicable in petroleum, chemical, and petrochemical industries, ensuring versatile performance.
Crucial for natural gas treatment processes, enhancing operational efficiency.
Integral to the steel-making industry, offering robust and reliable solutions.
Vital for power plants, ensuring optimal energy production.
Enhances air conditioning systems, providing efficient cooling solutions.
Essential for compressor coolers, ensuring reliable cooling performance.
KL Footed Fin / Knurled L Footed Fin
The KL fin is also known as the knurled L fin, exemplifying versatility in design. This finned tube, closely resembling the Wrap-On fin, benefits from advanced Wrap-On and Embedded techniques for superior performance. The fins are meticulously crafted from strips shaped into an L contour, elegantly rolled into a taper that encourages a dynamic curl. It is then expertly helically wound onto the tube in an endless loop under careful tension, ensuring durability. The fin wraps around the tube, achieving a perfect embrace. A sophisticated spinning tool knurls the base tube, embedding the fin foot into the knurling, thus creating a robust bond and enhanced thermal efficiency.
With precise fin strip selection, each fin's foot tightly meets the subsequent fin, leaving no space, amplifying corrosion protection. This unique design effectively shields the tube from corrosive elements. Mirroring L fins, the fin ends are secured to prevent unwinding, ensuring stability. KL -Foot tension wound finned tubes are the preferred choice in metal applications, thanks to their impressive properties. With a maximum operating temperature reaching up to 320°C (608°F), they are ideal for demanding environments.
Advantages:
Corrosion-resistant Tubes, crafted for longevity.
Exceptional vibration resistance, ensuring continuous performance.
Able to withstand extreme temperatures of up to 320°C (608°F).
Combining high thermal performance and stress resistance with air corrosion protection, creating an unmatched solution.
KL fins offer versatility, allowing them to replace any form of finned tube seamlessly.
LL-Foot Fin / Overlapped L
Crafted from strips, similar to L type, except with a precision-stepped double L shape, rolled into a taper for a sophisticated curl. The LL-Foot Fin - Overlapped L is skillfully helically coiled onto a tube under tension, ensuring a firm fit. The fin clings to the tube with one fin elegantly overhanging the next, ensuring full base tube coverage. This design significantly enhances corrosion protection. In corrosive environments, this tube type serves as a cost-effective alternative to pricier extruded fin options.
Ends are secured like L fins for additional stability. The LL-type fin tube can endure temperatures up to 350 degrees Fahrenheit (177°C), making it ideal for intense applications.
