L-Foot Finned Tube
This L-Footed finned tubing is a marvel of engineering, offering an exceptional combination of high efficiency and cost-effectiveness. It ensures optimal heat transfer even at lower temperatures, making it a practical choice for various industrial applications. The innovative L-shaped design is meticulously crafted to hold the fins rigidly in place, ensuring they withstand the challenges of heat cycling and high-velocity air vibrations.
The L-Foot Finned Tube is available in an array of variations, tailored to further enhance its performance and versatility:
Knurled Fin - Featuring an interference fit type fin, this variation incorporates mechanical knurling on the fin material, providing a robust bond between the fin and the tube wall surface.
LL Fin - The Double Overlap fin, known as the double LL, offers comprehensive coverage with a double strip thickness, ensuring robust protection and enhanced performance of the base tube.
Perforated L Fin - Ingeniously designed, this variation introduces 'tear drop' slits along the helix, disrupting airflow to increase efficiency and heat dissipation.
L-Foot Fin / Wrap-On Fin
L-Foot Tension Wound Finned Tubes Commonly referred to as Wrap-On Finned Tubes, these are ideal for applications with temperatures up to 300 degrees Fahrenheit, where a measure of tube wall protection is necessary for low-temperature environments. These finned tubes feature a thin aluminum fin strip helically wound and tightly wrapped around the tube circumference for utmost efficacy. The distinct 'foot' profile is initially formed on one edge of the fin strip, giving rise to the name L-Foot. Once formed, the strip is tightly wound around the tube, with the foot securing itself firmly to the tube's outer surface. The short horizontal limb of every L contacts the base-tube surface, ensuring complete coverage and maximum heat transfer efficiency. Through the tension generated during the winding process, the fin foot is seated powerfully against the tube, maintaining a strong and lasting bond. This L-footed finned tubing is crafted to deliver the best heat transfer performance, even when operating at lower temperatures. Ingeniously designed with an L-shape, it guarantees a robust hold against the rigors of heat cycling and high-speed air vibration. Additionally, this fin design offers a degree of atmospheric protection, shielding the tube wall from potential corrosion impacts. The broad interfacial contact between the tube and the finning significantly enhances the heat transfer, setting a new standard for efficiency. This fin design stands out, delivering impressive efficiency while remaining cost-effective, proving to be an investment worth making.
To ensure durability, the ends of the fins are meticulously stapled, preventing the aluminum fin from unravelling and ensuring the contact between the fin foot and tube remains intact. Maintaining this contact is vital for the air cooler's operation, as it facilitates the seamless transfer of heat from the tube wall, through the fin, to the surrounding ambient air.
Advantages:
Ideal for low-temperature applications, offering an economical and efficient solution.
This particular finning type is the most budget-friendly method available, without compromising on efficiency and performance.
In the event of failure, the fins can be easily removed during production, allowing the bare tube to be reutilized for finning.
There's no necessity to carve a helical groove over the core tube, simplifying the manufacturing process.
The ability to place fins on a very thin-walled tube is especially advantageous when employing costly alloys as the core tube material.
Capable of withstanding temperatures up to 130°C, this tube offers protection against atmospheric corrosion and thermal stress, ensuring long-lasting performance.
Application:
Oil and gas refineries
Petroleum, chemical, and petrochemical industries
Natural gas treatment facilities
Steel making industry operations
Power plants seeking efficient cooling solutions
Air conditioning systems
Compressor coolers for enhanced performance
KL Footed Fin / Knurled L Footed Fin
The KL fin is a marvel of efficiency. This fin is elegantly known in the industry as the knurled L fin. This innovative finned tube, closely resembling the renowned Wrap-On fin, incorporates both Wrap-On and Embedded techniques for superior functionality. Crafted from strips prepared into an L shape akin to the traditional L type, these fins are artfully rolled into a taper, creating a graceful curl. Under precise tension, the fin is meticulously helically wound onto the tube in a seamless, continuous loop. The tube is securely enveloped and protected by the fin. A specialized spinning tool expertly knurls the base tube, allowing the fin's foot to integrate into the tube's knurling for a formidable bond and enhanced thermal efficiency.
When the right fin strip is used, each fin's foot perfectly aligns, ensuring no gaps, thus providing unmatched protection. This advanced design enhances the tube's resistance to corrosion. Mirroring the L fin's reliability, these fins are secured at both ends, preventing any unwinding. KL-Foot tension wound finned tubes shine in metal applications, offering reliable performance. Able to operate efficiently at a maximum temperature of 320°C (608°F), a testament to its robust design.
Unmatched Advantages:
Corrosion-resistant Tubes
Vibration resistance
Endures temperatures up to 320°C (608°F), showcasing its resilience.
A revolutionary combination of high thermal performance, stress resistance, and protection against air corrosion.
KL fins offer versatility, capable of replacing any finned tube with ease.
LL-Foot Fin / Overlapped L
These fins are crafted from strips similar to the L type but with a precisely controlled stepped double L shape, allowing it to curl beautifully. The LL-Foot Fin - Overlapped L is elegantly coiled onto a tube under tension for optimum fit. The fin gently clings to the tube, with each fin overhanging the next, ensuring complete coverage. This design provides exceptional protection against corrosion. In corrosive environments, this tube serves as an efficient alternative to more costly extruded type fins.
Fins are securely attached at both ends, maintaining the reliability similar to L fins. Optimal for temperatures reaching up to 350°F (177°C), ensuring performance in demanding conditions.
