Discover our diverse range of finned tubes, including tension wound finned tubes, embedded finned tubes, and extruded finned tubes, each designed to meet unique industrial cooling needs.
Crafted with precision, tension wound finned tubes are created by meticulously winding an aluminium or copper strip around the tube under controlled tension, ensuring optimal thermal efficiency. Our advanced strip winding technology produces a variety of fin types: L-Fin, LL-Fin, and KL-Fin, tailored for superior performance in heat transfer applications.
Embedded fins (G-Fins) are ingeniously crafted by embedding an aluminium or copper strip into a helical groove machined on the tube's outer surface, enhancing its thermal conductivity and durability.
Our finned tubes, including tension wound, embedded, and extruded variants, serve as critical components for air coolers in industries such as:
Power generation facilities utilizing heat exchangers across electric, nuclear, thermal, and geothermal power plants.
Steam condensate systems designed for efficient operation and heat management.
The chemical and petrochemical sector, where reliability and performance are paramount.
Food processing plants and refrigeration technology, ensuring optimal temperature control and energy efficiency.
Various industrial applications, including steel mills, incinerators, and gas compression facilities, where robust heat transfer solutions are essential.
L-Foot Finned Tube
Achieve superior heat transfer with our cost-effective L-footed finned tubing, engineered to deliver maximum efficiency at lower temperatures. The innovative L-shaped design ensures fins are held firmly, withstanding rigorous heat cycling and high-velocity air vibrations.
Our L-Foot Finned Tube can be customized with the following fin variations:
Knurled Fin - This interference fit fin features mechanical knurling, enhancing the bond between the fin material and the tube wall surface for improved thermal performance.
LL Fin - Known as the Double Overlap fin (Double LL), it provides enhanced coverage with double strip thickness, ensuring comprehensive protection of the entire base tube.
Perforated L Fin - This innovative design creates 'tear drop' slits along the helix, effectively disrupting airflow to boost heat exchange efficiency.
L-Foot Fin / Wrap-On Fin
L-Foot Tension Wound Finned Tubes Also referred to as Wrap-On Finned Tubes, these are ideal for low-temperature applications, offering protection for tube walls at temperatures up to 300 degrees Fahrenheit. These tubes feature an aluminium fin strip tightly wound in a helical pattern around the tube's circumference, enhancing contact and heat transfer. A 'foot' is skillfully formed on one side of the fin strip, giving rise to the name L-Foot. The strip is tightly wound around the tube, with the foot securely gripped against the tube's outer surface to ensure stability. The horizontal limb of each L is in complete contact with the base-tube surface, ensuring full coverage and enhanced thermal efficiency. The tension applied during fin wrapping ensures the fin foot is firmly seated on the tube, maintaining its position and enhancing efficiency. L-footed finned tubing is engineered to provide optimal heat transfer at lower operating temperatures. The robust L-shaped design secures the fins, enabling them to withstand heat cycling and high-speed air vibrations effectively. This design also provides a layer of atmospheric protection against corrosion, ensuring the longevity of the tube wall. The broad contact area between the tube and finning significantly boosts heat transfer capabilities. This fin design combines high efficiency with cost-effectiveness, making it a preferred choice for industrial applications.
The ends of the fins are stapled to prevent unravelling, maintaining the integrity and contact between the fin foot and the tube. This component is indispensable to the air cooler's functionality, as it efficiently channels heat from the tube wall, transferring it through the fin to the ambient air, ensuring optimal thermal exchange.
Advantages:
Perfectly tailored for low-temperature applications, ensuring reliable performance even in demanding conditions.
This finning type offers the most cost-effective solution compared to competing methods, making it an economical choice without compromising quality.
In the event of fin failure, the fins can be effortlessly detached during production, allowing for the continued use of the bare tube for re-finning processes.
There is no requirement to cut helical grooves into the core tube, simplifying the production process and reducing potential structural weaknesses.
The ability to attach fins to a very thin-walled tube is particularly advantageous when utilizing costly alloys as the core tube, optimizing resource usage and cost-efficiency.
The tube is engineered to withstand temperatures as high as 130°C, ensuring durability against atmospheric corrosion and thermal stress.
Application:
Deployed in Oil and Gas Refineries, it facilitates the seamless cooling of essential components.
Indispensable in the Petroleum, Chemical, and Petrochemical Industries for efficient thermal management.
Utilized in Natural Gas Treatment processes, enhancing system efficiency and reliability.
Vital in the Steel Making Industry, providing robust cooling solutions for high-temperature operations.
Integral to Power Plants, ensuring stable and consistent cooling performance under various operating conditions.
Ideal for Air Conditioning systems, contributing to energy-efficient climate control solutions.
Essential in Compressor Coolers, maintaining optimal thermal conditions for high-performance machinery.
KL Footed Fin / Knurled L Footed Fin
The KL fin is also recognized as the knurled L fin, earning its reputation through exceptional engineering and performance. This finned tube bears a striking resemblance to the Wrap-On fin and is crafted using a blend of Wrap-On and Embedded techniques, enhancing its versatility. The fins are crafted from strips carefully formed into an L shape comparable to the L type, before being rolled into a taper that naturally curls. It is then meticulously helically wound onto the tube in a seamless, continuous loop under tension, ensuring a snug fit. The tube is enveloped by the fin, enhancing thermal conductivity and structural integrity. A specialized spinning tool knurls the base tube, and the fin's foot is meticulously knurled into the base tube's knurling, resulting in a robust bond and superior thermal performance.
When the correct fin strip is used, the foot of one fin seamlessly meets the next, leaving no gap, thus bolstering the tube's protection against corrosion. This design helps safeguard the tube from corrosion, prolonging its lifespan and reliability. Similar to L fins, the fins are securely fastened at each end to prevent unwinding, ensuring stability and durability. In metal-related applications, KL-Foot tension wound finned tubes are typically the preferred choice, offering robust performance. Capable of operating at a maximum temperature of up to 320°C (608°F), it stands as a testament to its high-temperature resilience.
Advantages:
Corrosion-resistant Tubes that ensure longevity and dependable performance in harsh environments.
Exhibits exceptional Vibration resistance, maintaining structural integrity under dynamic conditions.
Engineered to endure temperatures reaching up to 320°C (608°F), ensuring unfaltering performance and reliability.
Combines high thermal performance and stress resistance with protection from air corrosion, creating a unique and unparalleled solution.
KL is versatile enough to replace any form of finned tube, offering a flexible and adaptable solution.
LL-Foot Fin / Overlapped L
The fins are crafted from strips in a process akin to the L-type, but with a foot meticulously shaped into a precise stepped double L, rolled into a taper allowing for curling. The LL-Foot Fin - Overlapped L is then helically wrapped onto a tube under tension, ensuring a snug and secure fit. The fin tightly embraces the tube, with each fin overlapping the foot of the next, providing complete coverage of the base tube. This design ensures the tube is well shielded from corrosion, enhancing its durability and lifespan. In corrosive environments, this form of tube is frequently selected as a cost-effective alternative to the more expensive extruded type fin, delivering similar protection at a reduced cost.
The fins are meticulously secured at each end, mirroring the tried-and-tested method used for L fins, ensuring stability and performance in every application. The robust LL-type fin tube stands the test of high temperatures, expertly engineered to withstand up to 350 degrees Fahrenheit (177°C), making it ideal for demanding thermal conditions.
