L-Foot Finned Tube
Discover the epitome of efficiency and cost-effectiveness with our L-footed finned tubing. Engineered for excellence, it ensures optimal heat transfer even at lower temperatures. With its innovative L-shaped configuration, this product guarantees superior rigidity, adeptly enduring both heat cycling and the intense vibrations of high-velocity air.
The versatile L-Foot Finned Tube can be customized with the following fin variations:
Knurled Fin - Experience the precision of an interference fit fin, where mechanical knurling firmly affixes the fin material to the tube wall surface.
LL Fin - Double Overlap Fin: Offering comprehensive coverage, the double LL design delivers a robust double strip thickness across the entire base tube.
Perforated L Fin - Innovative 'tear drop' slits along the helix break up airflow, enhancing performance with a unique fin face enhancement.
L-Foot Fin / Wrap-On Fin
L-Foot Tension Wound Finned Tubes Known also as Wrap-On Finned Tubes, these are perfectly suited for applications where temperatures are maintained below 300 degrees Fahrenheit. Ideal for low-temperature scenarios necessitating tube wall protection. Crafted with precision, L-Foot tension wound finned tubes feature a fine aluminum fin strip, meticulously wound helically around the tube's circumference. A strategic 'foot' is meticulously formed on one side of the fin strip, giving rise to the name L-Foot. The strip is expertly wound tightly around the tube, ensuring the foot is firmly seated on the tube's outer surface. The short horizontal limb of the L makes full contact with the base-tube surface, providing complete coverage. The tension in the fin strip as it wraps around the tube ensures the fin foot is securely seated, holding the fin steadfastly in place. Our L-footed finned tubing is engineered to deliver unparalleled heat transfer efficiency at reduced temperatures. Its ingenious L-shaped design secures fins with unmatched rigidity, expertly handling both heat cycling and high-velocity air vibrations. This fin design also offers a level of atmospheric protection, safeguarding the tube wall against potential corrosion. The extensive contact surface between the finning and the tube significantly amplifies heat transfer capabilities. A marvel of design, this fin combines superior efficiency with significant cost savings.
The fin ends are securely stapled, preventing the aluminum fin from unraveling and ensuring continued contact between the fin foot and the tube. This precise contact is vital for air cooler operations, facilitating the efficient transfer of heat from the tube wall through the fin to the ambient air.
Advantages:
Optimal for low-temperature applications
Among the most cost-effective finning methods available.
Easily removable failed fins during production allow for reuse of the bare tube for finning.
No need for creating a helical groove on the core tube.
Allows for fin placement on very thin-walled tubes, which is especially advantageous when using costly alloys as core tubes.
Capable of withstanding temperatures up to 130°C, free from atmospheric corrosion or thermal stress risks.
Application:
Oil and gas refineries
Petroleum, chemical, and petrochemical industries
Natural gas treatment
Steel making industry
Power plants
Air conditioning
Introducing our state-of-the-art Compressor Coolers, engineered for maximum efficiency and performance. These innovative units are essential for maintaining optimal temperatures, ensuring your systems run smoothly and reliably.
Discover the advanced KL Footed Fin and Knurled L Footed Fin, expertly crafted for superior heat transfer and durability. These fins are the pinnacle of engineering excellence, providing unmatched thermal efficiency.
The revolutionary KL Fin design is at the forefront of finned tube technology, offering unparalleled performance and reliability. Also recognized as the Knurled L Fin, this innovative product sets a new standard in efficient heat exchange. This finned tube, nearly indistinguishable from the Wrap-On fin, is crafted using a blend of Wrap-On and Embedded techniques, ensuring peak performance and versatility. Our fins are meticulously fashioned from strips, skillfully shaped into an L form akin to the traditional L type, and then artistically rolled into a taper that naturally curls for optimal function. Under precise tension, these fins are helically wound onto the tube in a seamless loop, guaranteeing continuous performance and reliability. Ingeniously designed, the fin embraces the tube, ensuring maximum surface contact for increased thermal efficacy. Utilizing advanced spinning tools, the base tube is knurled, allowing the fin's foot to interlock with the base, creating an unyielding bond that skyrockets thermal performance.
Our precision-engineered fin strips ensure that each fin snugly fits against the next, leaving no gaps and maximizing thermal conduction while safeguarding against corrosion. This innovative design significantly enhances the tube's resistance to corrosion, providing long-lasting protection and reliability. Mirroring the secure attachment method of L fins, the fins are fastened at both ends, ensuring durability and preventing unwinding. In the realm of metal applications, KL Foot tension wound finned tubes are the preferred choice, offering unmatched reliability and superior thermal efficiency. Our products boast an impressive maximum operating temperature of up to 320°C (608°F), ensuring robust performance in extreme conditions.
Outstanding Advantages:
Corrosion-resistant Tubes that stand the test of time, maintaining integrity and performance.
Impressive Vibration Resistance for stable and reliable operation even in challenging environments.
Engineered to withstand temperatures soaring up to 320°C (608°F), ensuring unwavering performance.
Combining high thermal performance with stress resistance, and fortified with air corrosion protection, this product offers a truly unmatched solution in heat exchange technology.
Our KL finned tubes are versatile, adaptable for replacing any existing finned tube with superior results.
Introducing the LL-Foot Fin, an Overlapped L design crafted for enhanced protection and performance.
Expertly fashioned, these fins start as strips similar to the L type, but are meticulously crafted into a precise stepped double L shape, then elegantly rolled to a taper for optimal curling. The LL-Foot Fin - Overlapped L is meticulously helical coiled onto a tube, ensuring tight adherence under tension for uncompromised performance. Ingeniously designed, each fin seamlessly overlaps the next, completely enveloping the base tube for superior corrosion protection. This design ensures comprehensive protection from corrosion, making the tube resilient and durable under harsh conditions. In environments prone to corrosion, this tube design serves as a cost-effective alternative to the pricier extruded type fins, offering excellent protection and performance.
Fins are securely anchored at both ends, mirroring the reliable method used in L fins, ensuring integrity and longevity. The LL-type fin tube can endure temperatures up to 350°F (177°C), ensuring robust performance in demanding conditions.
