Crafted for excellence, the distinctive L-shaped design secures fins with unparalleled rigidity, enduring heat cycling and high-velocity air vibrations with ease.
Explore the versatile variations of the L-Foot Finned Tube fin designs to suit your specific needs:
Knurled Fin Featuring a robust interference fit, this fin type uses mechanical knurling to bind fin material securely to the tube wall surface, enhancing durability.
LL Fin The Double Overlap fin (Double LL) offers double strip thickness coverage over the entire base tube for superior protection and performance.
Perforated L Fin Boost airflow efficiency with 'tear drop' slits around the helix, meticulously designed to disrupt airflow, enhancing heat transfer capabilities.
L-Foot Fin / Wrap-On Fin
L-Foot Tension Wound Finned Tubes Also known as Wrap-On Finned Tubes, ideal for applications not exceeding 300 degrees Fahrenheit. Perfect for low-temperature scenarios requiring tube wall protection. Our L-Foot tension wound finned tubes feature a finely wound aluminum fin strip, helically encircling the tube for maximum efficiency. The fin strip forms a 'foot' on one side, giving this design its name, L-Foot. Wound with precision, the strip wraps tightly with the foot pressing against the tube's outer surface, ensuring steadfast contact. Each L's short horizontal limb remains in full contact with the base tube, ensuring complete coverage and optimized heat transfer. Tension inherent in the winding process ensures the fin foot grips the tube securely, maintaining firm placement. This innovative finned tubing ensures maximum heat transfer efficiency at cooler temperatures, redefining performance standards. The L-shaped design's rigidity is unparalleled, effortlessly enduring both heat cycling and air vibrations. With enhanced atmospheric protection, this fin design effectively shields the tube wall from corrosion. A broader contact area between the tube and finning elevates heat transfer, setting new benchmarks in efficiency. Admire the blend of high efficiency and cost-effectiveness that our fin design offers, delivering outstanding value.
The fin ends are securely stapled to prevent unraveling, maintaining vital contact between the fin foot and the tube. This crucial contact ensures heat efficiently transfers from the tube wall through the fin to the ambient air, optimizing cooler performance.
Advantages:
Engineered for excellence, ideal for low-temperature applications.
Our finning method stands as the most cost-effective solution, surpassing alternative options.
During production, failed fins are effortlessly removed, allowing the bare tube to be re-used for re-finning, optimizing resource use.
Avoid the need for helical grooves on the core tube, simplifying the manufacturing process.
Fins can be applied to ultra-thin-walled tubes, enabling the use of expensive alloys as core tubes, maximizing material efficiency.
Capable of withstanding temperatures up to 130°C, our tubes offer robust resistance to atmospheric corrosion and thermal stress.
Application:
Oil and gas refineries
Petroleum, chemical, and petrochemical industries
Natural gas treatment
Steel making industry
Power plants
Air conditioning
Compressor coolers
KL Footed Fin / Knurled L Footed Fin
The remarkable KL fin is also affectionately known as the knurled L fin, a masterpiece of engineering. This advanced finned tube is strikingly similar to the Wrap-On fin, crafted with a blend of Wrap-On and Embedded techniques, ensuring superior performance. Created from meticulously prepared strips, these fins boast a sophisticated L shape akin to the traditional L type. They are rolled into a taper, elegantly curling into form. The fin is then expertly helically wound onto the tube in an unbroken loop, maintaining tension for enhanced durability. The fin embraces the tube lovingly, providing an exceptional fit. A specialized spinning tool intricately knurls the base tube. The foot of the fin is then seamlessly knurled into the base tube's knurling, creating a firm bond and boosting thermal efficiency.
When the ideal fin strip is used, one fin foot meets the next without a gap, ensuring optimal protection and performance. This seamless design shields the tube from corrosive threats, preserving its longevity. Similar to L fins, these fins are anchored at each end, thwarting any possibility of unwinding. In the realm of metal applications, KL-Foot tension wound finned tubes are the preferred choice for their reliability and performance. Capable of withstanding temperatures up to 320°C (608°F), these tubes are built for rigorous conditions.
Outstanding Advantages:
Tubes offering exceptional resistance to corrosion
Remarkable vibration resistance
Resilient under high temperatures, up to 320°C (608°F).
This unique combination of high thermal performance, stress resilience, and air corrosion protection sets this product apart.
KL finned tubes stand ready to replace any existing finned tube designs with ease.
LL-Foot Fin / Overlapped L
Fins are crafted from precisely prepared strips, similar to the L type. The foot is fashioned into a controlled stepped double L shape, rolled gracefully into a taper to curl. The LL-Foot Fin, or Overlapped L, is then helically coiled under tension onto the tube. The fin securely embraces the tube, with each fin overlapping the foot of the next, ensuring the base tube is thoroughly covered. This complete coverage provides robust protection against corrosion. In corrosive environments, this tube is a cost-effective alternative to the pricier extruded type fins.
Fins are firmly secured at each end, maintaining their position, akin to L fins. The LL-type fin tube is designed to withstand temperatures up to 350°F (177°C), making it highly versatile.
