Discover a world of possibilities with our diverse range of finned tubes: tension wound finned tubes, embedded finned tubes, and extruded finned tubes, each designed to meet unique cooling needs.
Tension wound finned tubes are expertly crafted by meticulously wrapping a strip made from premium aluminium or copper around the tube under precise tension, ensuring optimal performance. Our advanced strip winding technology allows for the creation of various fin types, including L-Fin, LL-Fin, and KL-Fin, making it adaptable for multiple industrial applications.
Embedded fins (G-Fins) are innovatively engineered by winding an aluminium or copper strip into a helical groove precisely machined on the tube's outer surface, enhancing efficiency.
Tension wound, embedded, and extruded finned tubes are the cornerstone of air cooler technology, widely used across diverse sectors:
Heat exchangers for power plants, encompassing electric, nuclear, thermal, and geothermal facilities, benefit from our cutting-edge finned tube solutions.
Our products play a crucial role in steam condensate systems, ensuring seamless operation and enhanced efficiency.
In the chemical and petrochemical industry, our finned tubes stand out for their reliability and superior performance.
Food processing plants and refrigeration technology depend on our tubes for optimal cooling and efficiency.
Our industrial solutions are essential for steel mills, incinerators, and gas compression facilities, providing unparalleled performance.
L-Foot Finned Tube
Highly efficient yet cost-effective, our L-footed finned tubing delivers maximum heat transfer at lower temperatures, setting a new standard for performance. The distinctive L-shaped design ensures that the fins remain firmly in place, withstanding heat cycling and high-velocity air vibrations effortlessly.
Our L-Foot Finned Tube is available in the following fin variations to cater to diverse needs:
Knurled Fin - This unique fin features an interference fit, with mechanical knurling that secures the fin material to the tube wall surface for enhanced stability.
LL Fin - Double Overlap fin (The double LL) provides comprehensive coverage with a double strip thickness, protecting the entire base tube.
Perforated L Fin - Enhanced with 'tear drop' slits around the helix, this fin design disrupts airflow for superior performance.
L-Foot Fin / Wrap-On Fin
L-Foot Tension Wound Finned Tubes Also known as Wrap-On Finned Tubes, these are ideal for low-temperature applications, offering tube wall protection up to 300 degrees Fahrenheit. L-Foot tension wound finned tubes feature a thin aluminium fin strip, expertly wound in a helical pattern around the tube for maximum efficiency. A distinctive 'foot' is crafted on one side of the fin strip, giving rise to the name L-Foot. The strip is then meticulously wound around the tube, with the foot securely resting on its outer surface. Each L's short horizontal limb makes full contact with the base-tube surface, providing complete coverage. The tension in the fin strip during wrapping ensures a firm seating of the fin foot on the tube, maintaining stable operation. Our L-footed finned tubing is engineered to deliver maximum heat transfer at lower temperatures, redefining efficiency. With a unique L-shaped design, the fins are held rigidly to withstand both heat cycling and high-velocity air vibrations. This fin type offers excellent atmospheric protection, safeguarding the tube wall against corrosion. The extensive contact surface between the tube and the fin enhances heat transfer, setting new benchmarks in efficiency. Our innovative fin design is highly efficient yet remains cost-effective, providing unparalleled value.
Fin ends are stapled to ensure the aluminium fin remains secure, maintaining firm contact between the fin foot and tube, preventing unwinding. This contact is vital for the seamless function of the air cooler, facilitating efficient heat transfer from the tube wall, through the fin, and into the ambient air, ensuring optimal cooling performance.
Advantages:
Ideal for low-temperature applications, providing flexibility and reliability.
The finning type stands as the most cost-effective method, offering superb value compared to alternatives.
Failed fins can be effortlessly removed during production, allowing for the reuse of the bare tube in finning processes.
No helical groove is necessary on the core tube, simplifying the installation process.
The design accommodates the placement of fins on very thin-walled tubes, especially beneficial when using expensive alloys as the core tube.
The tube can endure temperatures up to 130°C while resisting atmospheric corrosion and thermal stress, ensuring durability.
Application:
Oil and gas refineries: Elevating efficiency in energy production.
Petroleum, chemical, and petrochemical industries: Enhancing processing capabilities.
Natural gas treatment: Optimizing purification processes.
Steel making industry: Supporting robust manufacturing operations.
Power plants: Ensuring sustainable energy output.
Air conditioning: Improving climate control systems.
Compressor coolers: Boosting performance and longevity.
KL Footed Fin / Knurled L Footed Fin
The KL fin is also identified as the knurled L fin, celebrated for its enhanced bonding technique. This finned tube mirrors the Wrap-On fin, crafted through a combination of Wrap-On and Embedded methods for superior results. Fins are meticulously shaped from strips into an L shape, then rolled to curl, achieving a perfect fit. They are helically wound around the tube in a continuous, tensioned loop for maximum efficiency. The tube is snugly embraced by the fin, ensuring excellent thermal contact. A spinning tool knurls the base tube, interlocking the fin foot with the knurling for a tight bond and enhanced thermal performance.
Using the correct fin strip, the foot of one fin meets the next, with no gaps, enhancing structural integrity. This tight configuration provides exceptional protection against corrosion. Similar to L fins, they are anchored at each end, preventing unwinding for stability. In metal applications, KL-Foot tension wound finned tubes are the preferred choice for reliability. Capable of operating at temperatures up to 320°C (608°F), delivering robust performance.
Advantages:
Tubes resistant to corrosion, promising longevity and reduced maintenance.
Engineered for vibration resistance, maintaining integrity under dynamic conditions.
Withstands temperatures up to 320°C (608°F) with remarkable resilience.
Combining high thermal performance with stress resistance and air corrosion protection offers a unique and powerful solution.
KL fins can seamlessly replace any form of finned tube, offering versatility in application.
LL-Foot Fin / Overlapped L
Fins are fashioned from strips, akin to the L type, but with a stepped double L shape for added precision and protection. The LL-Foot Fin - Overlapped L is helically coiled onto the tube under tension, providing a complete wrap. Fin engages the tube, with each fin overhanging the foot of the next, ensuring the base tube is fully shielded. This comprehensive coverage affords exceptional corrosion protection, safeguarding the tube's longevity. In challenging and corrosive environments, our Superior G Type Embedded Finned Tube serves as a premium yet cost-effective alternative to the pricier extruded finned tubes. It promises durability and reliability without compromising on efficiency.
Ingeniously designed, the fins are securely attached at both ends in a manner similar to the trusted L fins, ensuring stability and consistent performance in demanding applications. Our robust LL-type fin tube is engineered to endure temperatures soaring up to 350 degrees Fahrenheit (177 degrees Celsius), making it a versatile choice for high-temperature operations.
