L-Foot Finned Tube
Experience unparalleled efficiency combined with cost-effectiveness with our L-footed finned tubing, designed to deliver superior heat transfer even at lower temperatures. Ingeniously crafted with a distinctive L-shaped design, these fins are engineered to remain steadfast, enduring both heat cycling and the rigorous demands of high-velocity air currents.
The versatile L-Foot Finned Tube is available in the following innovative fin variations:
Knurled Fin - Featuring an interference fit, this fin showcases mechanical knurling that seamlessly integrates the fin material with the tube wall surface.
LL Fin - With a double overlap configuration, the LL Fin ensures comprehensive coverage with a dual strip thickness that envelops the entire base tube.
Perforated L Fin - Enhancing airflow dynamics, this fin design boasts 'tear drop' slits around its helix, ingeniously disrupting air flow for improved performance.
L-Foot Fin / Wrap-On Fin
L-Foot Tension Wound Finned Tubes Known also as Wrap-On Finned Tubes, these are ideal for applications with temperatures up to 300 degrees Fahrenheit, providing essential tube wall protection for low-temperature scenarios. Constructed with precision, L-Foot tension wound finned tubes consist of thin aluminum fin strips meticulously wound in a helical pattern around the tube's circumference. Crafted with a 'foot' on one side, these fin strips earn their L-Foot name by their distinct formation. The strip is expertly wound around the tube, ensuring the foot presses firmly against the outer surface of the tube. Each L's short horizontal limb maintains full contact with the base tube surface, ensuring complete coverage and enhanced efficiency. The tension generated in the fin strip as it wraps around the tube provides the necessary force to firmly seat the fin foot, securing it in place. Our L-footed finned tubing maximizes heat transfer efficiency even at reduced temperatures. This uniquely designed L-shaped configuration ensures the fins are securely held, capable of withstanding both heat cycling and high-velocity air-induced vibrations. Additionally, this fin style offers a protective barrier for the tube wall against potential atmospheric corrosion. The expansive contact surface between tube and fin enhances overall heat transfer proficiency. This fin design promises high efficiency without compromising on cost-effectiveness.
Ends of the fins are securely stapled, preventing unraveling and maintaining consistent contact between the fin foot and tube surface. This vital contact is crucial to the air cooler's performance, facilitating efficient heat transfer from the tube wall, through the fin, to the ambient air.
Advantages:
Perfectly suited for low-temperature applications
This finning method is the most economically efficient compared to others.
Easily removable failed fins during production allows for reuse of the bare tube in finning.
No need for helical grooves on the core tube, enhancing manufacturing efficiency.
Fins can be applied to thin-walled tubes, especially beneficial when using expensive alloy core tubes.
Capable of withstanding temperatures up to 130°C without risking atmospheric corrosion or thermal stress.
Application:
Oil and gas refineries
Petroleum, chemical, and petrochemical industries
Natural gas treatment facilities
Steel manufacturing industry
Power generation plants
Air conditioning systems
Compressor coolers are pivotal components in numerous industrial applications, engineered to optimize thermal efficiency and extend the lifespan of machinery.
KL Footed Fin / Knurled L Footed Fin are exquisite engineering marvels, designed to significantly enhance heat transfer efficiency.
The KL fin represents an advanced evolution in fin technology. is also known as the knurled L fin, a name that reflects its distinguished design and functionality. This finned tube stands out due to its similarity to the Wrap-On fin, crafted using the sophisticated Wrap-On and Embedded techniques for increased durability. Fins are meticulously crafted from strips shaped into an L form, then artfully rolled into a taper that elegantly curls. These fins are then expertly helically wound onto the tube in a continuous loop, ensuring optimal tension and performance. The fin warmly embraces the tube, creating a seamless bond that enhances efficiency. A precision spinning tool knurls the base tube, seamlessly integrating the foot of the fin into the knurling, establishing an unbreakable bond and elevating thermal performance.
When the correct fin strip is used, each fin joins seamlessly with the next, leaving no space—a testament to precision engineering. Such precise construction helps shield the tube from corrosion, ensuring longevity and reliability. Mimicking the classic L fins, the fins are securely affixed at each end to prevent any potential unwinding. In the realm of metal applications, KL-Foot tension wound finned tubes are the go-to choice, exemplifying versatility and reliability. Capable of withstanding up to a maximum operating temperature of 320°C (608°F), they offer remarkable resilience.
Advantages are numerous:
Tubes that resist corrosion over time, maintaining their structural integrity.
Exceptional vibration resistance, ensuring stability in demanding environments.
Withstanding temperatures up to 320°C (608°F) demonstrates their robust thermal capacity.
Combining high thermal performance, stress resistance, and protection from air corrosion creates an unparalleled combination.
KL can seamlessly replace any form of finned tube, offering flexibility and adaptability.
LL-Foot Fin / Overlapped L fins showcase engineering brilliance with their unique structure.
Fin strips are formed into a carefully controlled double-stepped L shape, perfectly rolled into a taper. The LL-Foot Fin - Overlapped L is then meticulously helically coiled onto the tube under precise tension. The fin tenaciously grips the tube, with overhanging fins providing full coverage of the base tube. As a result, the tube receives exceptional protection from corrosion, enhancing its durability. In environments susceptible to corrosion, this tube is a cost-effective alternative to pricier extruded type fins.
Fins are secured at each end with the same reliability as L fins, ensuring steadfast performance. The LL-type fin tube excels in temperatures up to 350 degrees Fahrenheit (177°C), showcasing its superior thermal capacity.
parameters remain consistent and reliable in various applications.
