We proudly offer a diverse array of finned tubes, including tension wound finned tubes, embedded finned tubes, and extruded finned tubes. Each of these is designed to meet specific industrial needs, ensuring versatility and high performance in a variety of applications.
Tension wound finned tubes are masterfully crafted by winding a durable strip of aluminium or copper around the tube under precise tension, ensuring robust construction and optimal performance. Our advanced strip winding technology allows for the production of various fin types, including L-Fin, LL-Fin, and KL-Fin, each offering unique advantages and efficiencies.
Embedded fins (G-Fins) are meticulously manufactured by winding an aluminium or copper strip into a precisely machined helical groove on the tube's outer surface, ensuring maximum durability and efficiency.
Tension wound finned tubes, embedded finned tubes, and extruded finned tubes serve as the primary components for air coolers, with common applications spanning:
Heat exchangers within power plants, including electric, nuclear, thermal, and geothermal sectors, benefit from our cutting-edge technology.
Steam condensate systems that require reliable and efficient thermal management solutions.
Industries spanning the chemical and petrochemical sectors, where precise temperature control is paramount.
Food processing facilities and advanced refrigeration technology systems that demand superior heat exchange solutions.
A wide range of industrial applications, including steel mills, incinerators, and gas compression facilities, are enhanced by our finned tube solutions.
L-Foot Finned Tube
L-Footed finned tubing stands out for its efficiency and cost-effectiveness, offering exceptional heat transfer capabilities at lower temperatures, making it ideal for budget-conscious applications. The ingenious L-shaped design firmly secures the fins, enabling them to endure intense heat cycling and high-velocity air vibrations.
The L-Foot Finned Tube is available in several innovative fin variations, including:
Knurled Fin - Featuring an interference fit, this type boasts mechanical knurling of the fin material onto the tube wall surface, enhancing its hold.
LL Fin - Double Overlap fin, known for providing a robust double strip thickness coverage across the entire base tube, optimizing protection and performance.
Perforated L Fin - This enhancement introduces 'tear drop' slits along the fin's helix, effectively disrupting airflow for enhanced thermal performance.
L-Foot Fin / Wrap-On Fin
L-Foot Tension Wound Finned Tubes also known as Wrap-On Finned Tubes, are tailored for applications where temperatures remain below approximately 300 degrees Fahrenheit, offering low-temperature protection for the tube wall. These tubes are constructed with a delicate aluminium fin strip, wound tightly in a helical pattern around the tube circumference for maximum efficiency. A 'foot' is strategically formed on one side of the fin strip, giving rise to the name L-Foot. The strip is then secured tightly around the tube, ensuring the foot remains in firm contact with the tube's outer surface. The short horizontal limb of each L is in intimate contact with the base tube surface, guaranteeing complete coverage and optimal heat transfer. The tension applied to the fin strip during wrapping ensures the fin foot is forcefully seated on the tube, maintaining a solid and dependable hold. L-footed finned tubing is celebrated for its ability to maximize heat transfer efficiency at lower temperatures, making it an industry favorite. The clever L-shaped configuration keeps the fins rigid against the challenges of heat cycling and high-velocity air vibrations, ensuring long-lasting performance. This fin design also provides a certain level of atmospheric protection to the tube wall, safeguarding against corrosion. The expansive contact surface between the tube and the finning significantly elevates heat transfer efficiency. This innovative fin design is both highly efficient and cost-effective, providing superior performance without breaking the bank.
To prevent the aluminium fins from unwinding and losing essential contact between the fin foot and the tube, the ends are strategically stapled. This secure contact is vital for the air cooler's operation, facilitating seamless heat transfer from the tube wall through to the ambient air.
Advantages:
Perfectly engineered for low-temperature applications, ensuring optimal performance even in chillier conditions.
This finning method stands out as the most cost-efficient choice, offering significant savings compared to other techniques.
Experience seamless production efficiency with easily removable failed fins, allowing the reuse of the bare tube for finning again.
Eliminate the hassle of creating a helical groove on the core tube, simplifying the production process.
Fins can be adeptly positioned on ultra-thin walled tubes, an ideal feature when employing costly alloys as core tubes.
Built to endure, the tube resists temperatures up to 130°C without succumbing to atmospheric corrosion or thermal stress.
Application:
Ideal for integration in oil and gas refineries, driving efficiency and reliability.
Crucial for operations within the petroleum, chemical, and petrochemical industries.
Enhancing efficiency in natural gas treatment processes.
An asset to the evolving steel making industry.
Power plants benefit from its robust performance.
Optimizes air conditioning systems for superior climate control.
Enhances compressor cooler performance, ensuring longevity and efficiency.
KL Footed Fin / Knurled L Footed Fin
The KL fin is recognized as the knurled L fin. Almost mirroring the Wrap-On fin, this finned tube combines both Wrap-On and Embedded techniques for superior performance. Crafted from strips fashioned into an L shape akin to the L type, then rolled into a taper for a curling effect. Expertly helically wound onto the tube in a continuous loop under tension, ensuring firm placement. The fin snugly embraces the tube, providing a secure fit. A cutting-edge spinning tool knurls the base tube, integrating the fin's foot into the base tube's knurling, enhancing thermal performance.
With precise fin strip usage, each fin neatly connects to the next, leaving no gaps, fortifying against corrosion. This meticulous design shields the tube from the risk of corrosion. In a manner akin to L fins, end attachments prevent unwinding, ensuring stability. KL-Foot tension wound finned tubes are predominantly used in metal-associated applications. Withstands an impressive maximum operating temperature of up to 320°C (608°F), offering remarkable durability.
Advantages:
Corrosion-resistant Tubes
Exhibits excellent vibration resistance, ensuring long-term reliability.
Capable of withstanding extreme temperatures of up to 320°C (608°F), delivering exceptional performance.
Combines high thermal performance and stress resistance with unmatched protection from air corrosion, creating a unique advantage.
KL fins provide a versatile solution, capable of replacing any form of finned tube.
LL-Foot Fin / Overlapped L
Fins crafted from strips similar to the L type, but with a meticulously controlled double L shape, rolled for a curling effect. The LL-Foot Fin - Overlapped L is expertly helically coiled onto a tube under tension for maximum efficacy. Fin adeptly clings to the tube, with each fin overhanging the foot of the subsequent fin, ensuring complete coverage. This configuration offers comprehensive corrosion protection for the tube. In corrosive environments, this tube type serves as a cost-effective alternative to pricier extruded fin types.
Fins are secured at both ends, mirroring the technique used for L fins, ensuring structural integrity. The LL-type fin tube, a marvel of modern engineering, is expertly crafted to withstand temperatures soaring up to 350 degrees Fahrenheit (177 degrees Celsius). This makes it an exceptional choice for high-temperature applications, ensuring optimum performance and reliability.
