Discover our diverse selection of finned tubes, including tension wound finned tubes, embedded finned tubes, and extruded finned tubes, designed to meet various air cooling needs.
Tension wound finned tubes are crafted by meticulously winding a strip of premium aluminium or copper around the tube while maintaining precise tension. Our strip winding technology delivers a variety of fin types, such as the robust L-Fin, the versatile LL-Fin, and the innovative KL-Fin.
Embedded fins (G-Fins) are expertly engineered by winding an aluminium or copper strip into a helical groove, precisely machined onto the tube's exterior surface.
Our tension wound, embedded, and extruded finned tubes serve as essential components in air coolers, excelling in a multitude of applications, such as:
Heat exchangers for a variety of power plants, including electric, nuclear, thermal, and geothermal power facilities.
Steam condensate systems, ensuring efficient heat exchange processes.
Chemical and petrochemical industry, facilitating optimal heat management.
Food processing plants and advanced refrigeration technology systems.
Industrial sectors like steel mills, incinerators, and gas compression facilities.
L-Foot Finned Tube
Our highly efficient yet cost-effective L-Foot finned tubing maximizes heat transfer even at lower temperatures. The distinctive L-shaped design ensures robust fin stability against heat cycling and high-velocity air vibrations.
Explore variations of the L-Foot Finned Tube, featuring:
Knurled Fin - This fin type features an interference fit with mechanical knurling for enhanced tube wall surface adherence.
LL Fin - The Double Overlap fin (Double LL) offers comprehensive double-layer coverage for the entire base tube.
Perforated L Fin - Unique 'tear drop' slits around the helix disrupt airflow, enhancing the fin face.
L-Foot Fin / Wrap-On Fin
L-Foot Tension Wound Finned Tubes also referred to as Wrap-On Finned Tubes, are ideal for applications under 300°F, providing essential tube wall protection at lower temperatures. Crafted from a thin aluminium fin strip, tightly wound helically around the tube's circumference for optimal performance. A 'foot' is carefully formed on one side of the fin strip, lending the design its name: L-Foot. This strip is then tightly wound around the tube, with the foot securely bearing on the tube's outer surface. Each 'L' limb's horizontal section touches the base-tube surface, ensuring complete coverage. Fin strip tension during wrapping ensures the fin foot is forcefully seated, maintaining firm contact. Enjoy maximum heat transfer efficiency at reduced temperatures with L-footed finned tubing. This unique L-shape design secures fins against heat cycling and high-velocity air vibration. This fin design also offers atmospheric protection against tube wall corrosion. Enhanced heat transfer is achieved through the broad contact surface between tube and finning. This design balances high efficiency with cost-effectiveness, delivering outstanding performance.
Fins are securely stapled at the ends to prevent unravelling and ensure consistent contact between fin foot and tube. This indispensable contact point is vital for the seamless operation of air coolers, as it facilitates the transfer of heat from the tube wall, navigating through the fin, and finally dispersing into the ambient air, ensuring optimal cooling performance.
Advantages of Our Product:
Ideal for low-temperature applications, ensuring unparalleled efficiency even in chilly conditions.
This finning type offers the most cost-effective solution, outshining other methods in economic efficiency.
Fins that fail can be effortlessly removed during production, allowing the bare tube to be refinned and reused, maximizing resource efficiency.
There's no requirement to carve a helical groove into the core tube, simplifying the process immensely.
Fins can be elegantly mounted on ultra-thin-walled tubes, an especially valuable feature when employing costly alloys as the core material, optimizing both performance and cost.
With the ability to endure temperatures up to 130°C, this tube resists atmospheric corrosion and thermal stress, guaranteeing durability and reliability.
Diverse Applications Include:
Essential in oil and gas refineries, ensuring efficient cooling solutions.
Widely used across the petroleum, chemical, and petrochemical industries, enhancing operational efficiency.
Perfect for natural gas treatment processes, ensuring reliable performance.
Invaluable to the steel making industry, supporting robust cooling requirements.
Indispensable in power plants, providing consistent cooling performance.
Vital for air conditioning systems, promoting effective and energy-efficient cooling.
Key component in compressor coolers, boosting operational reliability.
KL Footed Fin / Knurled L Footed Fin - A Revolution in Finned Tube Technology
Introducing the KL fin, also recognized as the knurled L fin, a hallmark of precision engineering. This finned tube mirrors the Wrap-On fin, crafted through the sophisticated Wrap-On and Embedded techniques for superior performance. Fins are meticulously crafted from strips shaped into an L structure comparable to the L type, then artfully tapered to induce curling. The fin is expertly helically wound onto the tube in a continuous loop under precise tension for maximum efficacy. The tube becomes snugly embraced by the fin, ensuring a secure fit. A spinning tool knurls the base tube while the foot of the fin is expertly integrated into the knurling, enhancing the bond and boosting thermal performance to new heights.
Proper fin strip utilization ensures no gaps between fins, with each fin seamlessly abutting the next, optimizing protection. This strategic design choice aids in safeguarding the tube against corrosion, extending its lifespan. Much like L fins, these fins are securely fastened at both ends to avert unwinding, ensuring longevity. KL -Foot tension wound finned tubes are predominantly used in metal-related applications, showcasing their versatility. Capable of handling a maximum operating temperature of up to 320°C (608°F), ensuring robust performance under extreme conditions.
Outstanding Advantages Include:
Corrosion-resistant Tubes - Built to withstand harsh environments, ensuring longevity.
Boasts high vibration resistance, ensuring stability and performance under dynamic conditions.
Remarkably withstands temperatures soaring up to 320°C (608°F), maintaining operational integrity.
This unique blend of high thermal performance, stress resistance, and protection against air corrosion is unparalleled.
KL fins offer the flexibility to replace any finned tube variant, showcasing their adaptability.
LL-Foot Fin / Overlapped L - An Innovation in Finned Tubing
Fins are meticulously crafted from strips similar to the L type, but with a refined stepped double L shape foot, tapered and curled for precision. The LL-Foot Fin - Overlapped L is artfully helically coiled onto a tube under tension, ensuring a perfect fit. The fin clings tightly to the tube, with one fin elegantly overhanging the foot of the next, providing comprehensive coverage. This configuration offers exceptional protection against corrosion, safeguarding the tube and extending its service life. In environments where corrosion is a concern, this innovative tube design serves as a cost-effective alternative to the traditional extruded fin type, offering exceptional durability and performance.
The fins are expertly secured at either end, employing the same reliable method as used for L fins, ensuring stability and efficiency. Designed for high-temperature resilience, the LL-type fin tube competently withstands temperatures reaching up to 350 degrees Fahrenheit (177C degree), making it a versatile choice for demanding applications.
