L-Foot Finned Tube
Experience exceptional efficiency and cost savings with our L-footed finned tubing, engineered to deliver peak heat transfer even at reduced temperatures. Embrace the strength and reliability of our L-shaped design, expertly crafted to secure fins in place, enduring heat cycling and high-velocity air vibrations with ease.
Discover the versatility of the L-Foot Finned Tube with available fin variations:
Knurled Fin - A precision-engineered interference fit fin, featuring mechanical knurling to enhance the fin’s adhesion to the tube wall surface.
LL Fin - The robust Double Overlap (Double LL) Fin creates a double strip thickness, ensconcing the entire base tube.
Perforated L Fin - Innovatively designed with 'tear drop' slits around the helix, this fin option disrupts airflow for enhanced performance.
L-Foot Fin / Wrap-On Fin
L-Foot Tension Wound Finned Tubes Also recognized as Wrap-On Finned Tubes, ideal for applications not exceeding 300°F, they provide optimal performance in low-temperature settings while offering tube wall protection. Our L-Foot tension wound finned tubes feature a tightly wound, helically arranged thin aluminum fin strip around the tube's circumference. A 'foot' is meticulously formed on one side of the fin strip, giving it the distinctive L-Foot designation. The fin strip is wound with precision, ensuring the foot maintains firm contact with the tube's exterior surface. The short, horizontal segment of each L ensures comprehensive coverage of the base-tube surface. The tension applied during the fin wrapping process ensures the fin foot is securely seated, maintaining a firm grip on the tube. L-footed finned tubing delivers superior heat transfer efficiency at reduced temperatures, offering remarkable thermal performance. Our L-shaped design, with its robust configuration, effectively secures fins, enduring both heat cycling and high-velocity air vibrations. The fin provides essential protection against atmospheric corrosion, safeguarding the tube wall over time. A broad contact surface between the tube and finning significantly amplifies heat transfer efficiency. This remarkably efficient fin design is both affordable and high-performing.
To prevent the unraveling of aluminum fins and maintain critical contact, fin ends are meticulously stapled. Maintaining this vital contact is crucial for optimal air cooler functionality, ensuring efficient heat transfer from the tube to the surrounding air.
Advantages:
Exceptionally suited for low-temperature applications
Represents a cost-effective finning method compared to alternatives.
Fins can be effortlessly replaced during production, allowing for the reuse of bare tubes for future finning.
Eliminates the need for a helical groove on the core tube, streamlining production.
Perfect for application on thin-walled tubes, especially beneficial when using costly alloy core tubes.
Capable of withstanding temperatures up to 130°C, without succumbing to atmospheric corrosion or thermal stress.
Applications:
Oil and gas refineries
Petroleum, chemical, and petrochemical sectors
Natural gas processing
Steel manufacturing industry
Power generation facilities
Air conditioning systems
Compressor coolers
KL Footed Fin / Knurled L Footed Fin
The KL fin is also known as the knurled L fin. This finned tube closely resembles the Wrap-On fin, crafted using a blend of both Wrap-On and Embedded techniques, ensuring superior performance. Ingeniously designed, the fins are crafted from expertly prepared strips, meticulously shaped into an L configuration akin to the traditional L type, and then rolled into a taper that encourages a graceful curl. Finishing with finesse, it is helically wound around the tube in a seamless, continuous loop under precision tension. The tube receives an affectionate embrace from the fin, ensuring impeccable contact. A sophisticated spinning tool elegantly knurls the base tube, with the fin's foot seamlessly integrated into the knurling, ensuring a robust bond and exceptional thermal efficiency.
Precision and craftsmanship ensure that when the correct fin strip is employed, the foot of one fin flawlessly aligns with the next, leaving no gaps, enhancing durability and efficiency. This meticulous design significantly bolsters the tube's resistance to corrosive elements. Mirroring the L fins' methodology, the fins are securely affixed at each extremity to prevent any unwinding, ensuring stability. For metal applications, KL-Foot tension wound finned tubes are the go-to choice, due to their reliability and performance. Designed to perform impeccably up to 320°C (608°F) maximum operational temperature.
Advantages:
Corrosion-resistant Tubes
Vibration resistance
Engineered to endure temperatures soaring up to 320°C (608°F).
A remarkable synergy of high thermal performance and stress resistance, coupled with formidable protection against air corrosion, defines its uniqueness.
The adaptability of KL finned tubes allows them to replace any other form of finned tube effortlessly.
LL-Foot Fin / Overlapped L
Crafted with precision, the fins originate from strips, reminiscent of the L type but enhanced with a meticulously controlled stepped double L shape, forming a taper that allows for a perfect curl. The LL-Foot Fin - Overlapped L is artfully helically coiled onto the tube under precision tension, ensuring firmness and reliability. The fin elegantly adheres to the tube, with each fin gracefully overhanging the foot of its successor, ensuring the base tube is entirely cloaked and protected. This comprehensive coverage guarantees robust protection against corrosion, extending the tube's lifespan. In environments prone to corrosion, this innovative tube is frequently chosen as a cost-effective alternative to the more expensive extruded type fins.
Fins are secured at each terminus, akin to the L fins, ensuring steadfastness and endurance. The LL-type fin tube thrives at temperatures reaching up to 350 degrees Fahrenheit (177°C), showcasing remarkable heat resistance.
