L-Foot Finned Tube
Experience efficiency and cost-effectiveness combined with our L-footed finned tubing, crafted to deliver exceptional heat transfer even at lower temperatures. Embrace innovation! With its distinctive L-shaped design, this tube ensures that fins remain steadfast, effectively combating heat cycling and enduring high velocity air vibrations.
Discover the versatile offerings of the L-Foot Finned Tube, tailored to meet various fin specifications:
Knurled Fin - Experience an interference fit type fin with the added benefit of mechanical knurling, securely attaching the fin material to the tube wall's surface for optimum performance.
LL Fin - The Double Overlap fin (the double LL) features a dual strip thickness, providing extensive coverage and protection to the entire base tube.
Perforated L Fin - This innovative enhancement incorporates 'tear drop' slits along the helix, ingeniously disrupting air flow for enhanced efficiency.
L-Foot Fin / Wrap-On Fin
L-Foot Tension Wound Finned Tubes Also recognized as Wrap-On Finned Tubes, these tubes excel in applications where temperatures are up to 300°F, making them ideal for low-temperature scenarios where tube wall protection is essential. The L-Foot tension wound finned tubes feature a meticulous design with a thin aluminum fin strip helically wound around the tube, ensuring a tight fit. A strategically formed 'foot' on one side of the fin strip initiates the name L-Foot, signifying its unique functionality. The fin strip is methodically wound around the tube, with the 'foot' resting firmly on the tube's outer surface, ensuring stability. Each short horizontal limb of the L-Foot makes complete contact with the base-tube surface, ensuring comprehensive coverage. The tension applied as the fin strip encircles the tube ensures the L-foot is securely seated, holding the fin steadfastly in place. Our L-footed finned tubing is engineered for maximum heat transfer efficiency at lower temperatures, setting a new standard in innovation. The exceptional L-shaped design guarantees fins remain securely in place, expertly managing heat cycling and high velocity air vibrations. This cutting-edge fin design provides a degree of atmospheric protection against corrosion, safeguarding the tube wall. The extensive contact surface between the tube and the finning significantly amplifies heat transfer, optimizing performance. This ingenious fin design marks the epitome of efficiency and cost-effectiveness, redefining industry standards.
Fin ends are meticulously stapled to prevent unraveling, ensuring constant contact between the fin foot and the tube for seamless operation. This contact is pivotal, facilitating the smooth transfer of heat from the tube wall through the fin, enriching the surrounding ambient air.
Advantages:
Perfectly suited for low-temperature applications, providing an edge in efficiency and functionality.
This finning type outshines others in cost-effectiveness, ensuring superior value.
Easily replace failed fins during production, allowing the bare tube to be reused for further finning.
No need for helical grooves on the core tube, simplifying production and reducing costs.
Capable of accommodating very thin-walled tubes, particularly beneficial when using expensive alloys as the core tube.
Withstands temperatures of up to 130°C without succumbing to atmospheric corrosion or thermal stress, ensuring durability.
Application:
Oil and gas refineries
Petroleum, chemical, and petrochemical industries
Natural gas treatment
Steel making industry
Power plants
Air conditioning
Compressor coolers
Discover our innovative KL Footed Fin, also known as the Knurled L Footed Fin, a marvel of engineering designed for optimal performance.
Our KL fin represents a pinnacle of precision and efficiency, engineered to cater to your advanced thermal management needs. Widely recognized as the knurled L fin, it stands as a testament to superior design and functionality. This finned tube, a close relative to the Wrap-On fin, is crafted using both Wrap-On and Embedded techniques for unmatched reliability. Crafted from strips meticulously prepared into an L shape, the fins are then rolled into a taper, creating a perfect curl. Employing a helical winding technique, the fin is seamlessly coiled onto the tube in a continuous loop under carefully applied tension. The fin embraces the tube, providing a snug fit that ensures consistent thermal exchange. A state-of-the-art spinning tool artfully knurls the base tube, integrating the fin's foot into the knurling, ensuring a bond that enhances thermal efficiency.
With the precise fin strip, each fin foot aligns with the next, eliminating gaps and boosting protection against corrosion. This design offers robust protection against corrosion, safeguarding the integrity of the tube. Much like the L fins, our fins are firmly anchored at each end, preventing any unwinding and ensuring durability. The KL -Foot tension wound finned tubes are the go-to choice for metal applications, providing superior thermal performance. Capable of withstanding up to 320°C (608°F), this product is designed for high-performance environments.
Advantages:
Corrosion-resistant Tubes
Impressive Vibration resistance
Engineered to endure temperatures soaring up to 320°C (608°F), ensuring robustness even in extreme conditions.
A unique blend of high thermal efficiency, stress resistance, and air corrosion protection sets our tubes apart.
Replace any finned tube with the versatile KL, designed for adaptability and performance.
LL-Foot Fin / Overlapped L
Similar to the L type, these fins are crafted from strips; however, the foot is precisely shaped into a double L, ready to curl seamlessly. The LL-Foot Fin - Overlapped L is expertly coiled around the tube under tension, ensuring close adherence. With a design that allows each fin to overlap the foot of the next, the tube is fully enclosed, offering complete protection. This construction ensures robust corrosion protection, maintaining the tube's longevity. In corrosive environments, this tube serves as a cost-effective alternative to pricier extruded types.
The secure attachment at each end, akin to L fins, guarantees stability and performance. The LL-type fin tube is adept for temperatures reaching up to 350 degrees Fahrenheit (177°C), showcasing its resilience.
