Discover the versatility of our advanced finned tube offerings: tension wound finned tubes, embedded finned tubes, and extruded finned tubes, each crafted for superior thermal efficiency and tailored to meet diverse industry demands.
Tension wound finned tubes are ingeniously crafted by precisely winding a metallic strip, composed of either aluminium or copper, around the tube under controlled tension, ensuring optimal heat transfer. Our strip winding technology delivers an array of fin styles, including L-Fin, LL-Fin, and KL-Fin, each meticulously designed to enhance thermal performance and maximize heat exchange efficiency.
Embedded fins (G-Fins) These fins are expertly engineered by embedding an aluminium or copper strip into a meticulously machined helical groove on the tube's outer surface, ensuring a durable and efficient heat transfer solution.
Our tension wound finned tubes, embedded finned tubes, and extruded finned tubes serve as pivotal components in air coolers, finding essential applications in the following fields:
Heat exchangers for power plants, encompassing electric, nuclear, thermal, and geothermal power plants, where they play a vital role in optimizing energy efficiency.
Steam condensate systems, where our finned tubes ensure effective heat exchange, enhancing the overall system reliability and performance.
Chemical and petrochemical industry, where they are integral to maintaining process stability and energy conservation.
Food processing plants and refrigeration technology, where they help achieve precise temperature control and energy savings.
Industrial applications, including steel mills, incinerators, and gas compression facilities, where they enhance operational efficiency and safety.
L-Foot Finned Tube
Our L-footed finned tubing combines exceptional heat transfer capabilities with cost-effectiveness, delivering maximum efficiency at lower temperature ranges. The distinctive L-shaped design ensures that fins remain securely in place, enduring heat cycles and high-velocity air vibrations with unwavering stability.
The L-Foot Finned Tube is available in various fin configurations, each designed to meet specific heat transfer needs:
Knurled Fin - This fin type features an interference fit, achieved through mechanical knurling of the fin material to the tube wall surface for enhanced thermal contact.
LL Fin - Double Overlap fin (The double LL) offers comprehensive double strip thickness coverage along the entire base tube for optimized thermal exchange.
Perforated L Fin - This innovative fin design disrupts airflow with 'tear drop' slits around the helix, enhancing heat transfer efficiency.
L-Foot Fin / Wrap-On Fin
L-Foot Tension Wound Finned Tubes Also known as Wrap-On Finned Tubes, these are ideal for applications where temperatures remain below 300 degrees Fahrenheit, providing necessary tube wall protection in low-temperature settings. L-Foot tension wound finned tubes consist of a thin aluminium fin strip expertly wound helically around the tube's circumference, ensuring robust thermal performance. A 'foot' is meticulously formed on one side of the fin strip, giving rise to the name L-Foot. The strip is then tightly wound around the tube, with the foot resting firmly on the tube's outer surface for optimal contact. Each L's short horizontal limb makes full contact with the base-tube surface, covering it entirely to enhance heat transfer. Tension in the fin strip during wrapping effectively seats the fin foot onto the tube, maintaining the fin's secure positioning. L-footed finned tubing maximizes heat transfer at lower temperatures, making it a highly efficient option for various applications. The unique L-shaped design ensures fins withstand thermal cycling and high-velocity air vibrations, providing enduring performance. This fin design offers significant atmospheric protection of the tube wall against corrosion, prolonging the life of the heat exchanger. The extensive contact surface between the tube and finning enhances heat transfer, optimizing efficiency for various industrial applications. This highly efficient yet cost-effective fin design is engineered to meet the demanding needs of modern industries.
The fin ends are securely stapled to prevent the aluminium fin from unravelling, ensuring consistent contact between the fin foot and the tube for optimal performance. This essential contact is the linchpin of the air cooler's operation, facilitating efficient heat transfer by seamlessly moving heat from the tube wall, traversing through the fin, and dissipating into the ambient air.
Advantages:
Ideal for low-temperature applications, ensuring optimal performance in cooler environments.
This finning type stands as the most cost-effective option when evaluated against other methods, providing excellent value.
Easily removable failed fins during production allow for reusing the bare tube, making the process both economical and efficient.
No need to create a helical groove on the core tube, simplifying the manufacturing process.
Fins can be elegantly placed on a very thin-walled tube, a particularly beneficial feature when utilizing costly alloy materials as the core tube.
The tube is robust enough to withstand temperatures soaring up to 130°C without succumbing to atmospheric corrosion or thermal stress, ensuring longevity and reliability.
Application:
Oil and gas refineries benefit from enhanced efficiency and durability.
A vital component in the petroleum, chemical, and petrochemical industries, optimizing operational efficiency.
Revolutionizes natural gas treatment processes with superior heat transfer capabilities.
Integral to the steel-making industry, ensuring optimal thermal regulation.
Power plants capitalize on its robust and efficient heat management.
Air conditioning systems experience improved performance and prolonged lifespan.
Compressor coolers achieve superior cooling efficiency with this technology.
KL Footed Fin / Knurled L Footed Fin
The KL fin is colloquially referred to as the knurled L fin. This finned tube shares a striking resemblance with the Wrap-On fin, crafted through a blend of Wrap-On and Embedded techniques. Crafted from strips prepared into an L shape akin to the L type, these fins are meticulously rolled into a taper, prompting them to curl. The fin is then artfully wound helically onto the tube in a continuous loop under tension, enhancing structural integrity. The fin embraces the tube intimately, ensuring a snug fit and optimal thermal contact. A meticulous process involving a spinning tool knurls the base tube, integrating the fin's foot into the knurling, forming a robust bond and enhancing thermal performance.
Utilizing the correct fin strip ensures that the foot of one fin seamlessly aligns with the next, eliminating gaps and maximizing coverage. This process significantly fortifies the tube against corrosion, safeguarding it effectively. Similar to L fins, these fins are securely attached at each end, effectively preventing unwinding. Typically employed in metal applications, KL-Foot tension wound finned tubes offer exceptional performance and resilience. Capable of operating at a remarkable maximum temperature of up to 320°C (608°F), showcasing its endurance.
Advantages:
Designed with corrosion-resistant tubes to ensure longevity in harsh environments.
Exhibits impressive vibration resistance, enhancing durability and stability.
Boasts an ability to withstand elevated temperatures of up to 320°C (608°F), perfect for high-heat applications.
A unique blend of high thermal performance and stress resistance with air corrosion protection, offering unmatched reliability.
KL fins can replace any form of finned tube, offering versatile adaptability.
LL-Foot Fin / Overlapped L
Fins are crafted from strips in a manner akin to the L type, with the foot shaped into a meticulously controlled stepped double L, then rolled to encourage curling. The LL-Foot Fin - Overlapped L is then helically coiled onto a tube under tension, ensuring secure attachment. The fin snugly adheres to the tube, with each fin elegantly overlapping the foot of the next, resulting in complete coverage of the base tube. This design effectively protects the tube from corrosion, ensuring durability and longevity. In environments where corrosion is a significant concern, the G Finned Tube Heat Exchanger with Embedded Fin Tube Technology offers a compelling alternative to the costly extruded type fin. This innovative design is frequently chosen for its superior performance and cost-effectiveness.
The fins of our advanced heat exchangers are meticulously secured at each end, following the same reliable methodology used for L fins, ensuring durability and efficiency in heat transfer. With its robust construction, the LL-type fin tube is engineered to withstand temperatures soaring up to 350 degrees Fahrenheit (177°C), making it an ideal choice for high-temperature applications.
