L-Foot Finned Tube
Discover the pinnacle of innovation with our L-footed finned tubing, crafted for exceptional efficiency and economy. This marvel offers superior heat transfer capabilities even at lower temperatures. Featuring a unique L-shaped architecture, our fins remain steadfast against heat cycling and high-velocity air vibrations, ensuring performance longevity.
Our L-Foot Finned Tube comes in the following fin variations:
Knurled Fin - Experience the precision of an interference fit type fin, where mechanical knurling seamlessly bonds the fin material to the tube wall surface.
LL Fin - Embrace the double overlap fin design, offering robust, double strip coverage that envelops the entire base tube.
Perforated L Fin - Enhance your airflow dynamics with 'tear drop' slits engineered around the helix to disrupt and optimize air flow.
L-Foot Fin / Wrap-On Fin
L-Foot Tension Wound Finned Tubes Known as Wrap-On Finned Tubes, perfect for low-temperature applications up to 300°F, adding a layer of protection to the tube wall. Constructed with precision, L-Foot tension wound finned tubes feature a thin aluminum fin strip meticulously wound around the tube circumference. The 'foot' formed on one side of the fin strip, gives the L-Foot its name. This strip is tightly wrapped around the tube, with the foot securely gripping the tube's surface, ensuring stability. Each L's horizontal limb snugly contacts the base-tube surface, providing complete coverage. The tension applied during wrapping ensures the fin foot remains firmly seated, maintaining robust contact. Our L-footed finned tubing is designed for peak heat transfer efficiency even at reduced temperatures. The revolutionary L-shaped design maintains structural integrity against heat cycling and rapid air flow vibrations. This fin design offers commendable atmospheric protection, safeguarding the tube wall from corrosion. The extensive contact surface between the tube and finning significantly amplifies heat transfer. Achieve remarkable cost efficiency without compromising effectiveness with this fin design.
Stapled fin ends prevent unraveling, ensuring continuous contact between fin foot and tube, crucial for optimal air cooler operation. Seamless heat transfer from the tube wall, through the fin, to ambient air is pivotal for performance.
Advantages:
Ideal for low-temperature applications, ensuring reliability and durability.
Our finning method stands as the most economical choice among alternatives.
Easily remove faulty fins during production, allowing for the reuse of bare tubes for seamless refinning.
No need for helical grooving on the core tube, simplifying production processes.
Efficiently place fins on thin-walled tubes, ideal when utilizing expensive alloy core tubes.
Withstand temperatures up to 130°C with confidence, free from atmospheric corrosion or 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 KL fin is also known as the knurled L fin. This exceptional finned tube, comparable to the Wrap-On fin, is crafted using both Wrap-On and Embedded techniques, ensuring superior performance. The fins, meticulously shaped from strips, are formed into an L configuration akin to the L type, then skillfully rolled into a taper, inducing a curling effect. Subsequently, it is helically wound onto the tube in a seamless, continuous loop, held under tension for optimal fit. The tube is tightly embraced by the fin, ensuring maximum contact and efficiency. A rotating tool knurls the base tube, intertwining the foot of the fin into the tube's knurling, culminating in a robust bond and enhanced thermal efficiency.
By employing the correct fin strip, each fin foot aligns perfectly with the next, leaving no gap between them. This tight configuration offers exceptional protection for the tube against corrosion. Like L fins, the ends of the fins are securely attached, preventing any unwinding. KL-Foot tension wound finned tubes are predominantly utilized in metal-related applications, offering unparalleled reliability. Capable of withstanding up to 320°C (608°F) maximum operating temperature
Advantages:
Corrosion-resistant Tubes, designed to endure the harshest environments.
Vibration resistance ensures durability and longevity.
It can withstand temperatures of up to 320°C (608°F), offering versatility in extreme conditions.
A remarkable combination of high thermal performance and stress resistance, coupled with protection against air corrosion, renders this product truly unique.
KL fins are versatile replacements for any form of finned tubes.
LL-Foot Fin / Overlapped L
Fins are expertly crafted from strips in a manner similar to L type, but with an intricately controlled stepped double L shape, rolled into a taper for enhanced curling. The LL-Foot Fin - Overlapped L is then carefully helically coiled onto a tube under precise tension. The fin clings firmly to the tube, with each fin's foot seamlessly overlapping the next, completely encasing the base tube. This configuration ensures the tube is exceptionally well-protected from corrosion. In corrosive environments, this type of tube is often chosen as a cost-effective alternative to the pricier extruded type fin.
Fins are secured at each end just like L fins, ensuring stability and reliability. The LL-type fin tube is designed for compatibility with temperatures up to 350°F (177°C), showcasing its adaptability.
