Product Description

Product Parameters

Explore our diverse array of finned tubes, including tension wound finned tubes, embedded finned tubes, and extruded finned tubes, each engineered for excellence.

Our tension wound finned tubes are meticulously crafted by spiraling a strip of premium aluminium or copper around the tube with precision tension. This strip winding technique produces an array of fin types such as the L-Fin, LL-Fin, and KL-Fin, each designed for optimal performance.

Embedded fins (G-Fins) are expertly crafted by winding an aluminium or copper strip into a strategically machined helical groove on the tube's outer surface.

Tension wound, embedded, and extruded finned tubes are pivotal components for air coolers, serving in various essential fields like:

Heat exchangers for power plants, including electric, nuclear, thermal, and geothermal facilities, ensuring optimal heat management.

Steam condensate systems, where efficiency and reliability are paramount.

Chemical and petrochemical industry, where robust performance is a necessity.

Food processing plants and cutting-edge refrigeration technology, ensuring consistent and safe temperature control.

Industrial sectors such as steel mills, incinerators, and gas compression facilities, where durability and efficiency are crucial.

L-Foot Finned Tube

Remarkably efficient and cost-effective, L-footed finned tubing guarantees superior heat transfer even at lower temperatures. The innovative L-shaped design securely holds fins to endure the challenges of heat cycling and high-velocity air vibrations.

Variations of the L-Foot Finned Tube include:

Knurled Fin - A finely crafted interference fit type fin, mechanically knurled to bond seamlessly with the tube wall surface.

LL Fin - Featuring Double Overlap fin, this design provides an extensive double strip thickness coverage over the entire base tube.

Perforated L Fin - Innovative 'tear drop' slits around the helix enhance airflow dynamics, breaking up air flow for increased efficiency.

L-Foot Fin / Wrap-On Fin

L-Foot Tension Wound Finned Tubes commonly referred to as Wrap-On Finned Tubes, these are ideal for applications under 300 degrees Fahrenheit, providing essential tube wall protection in low-temperature scenarios. These tubes are comprised of a thin, aluminium fin strip, helically wound with precision around the tube's circumference. A 'foot' is initially formed on one side of the fin strip, aptly named the L-Foot, laying the foundation for secure attachment. This strip is meticulously wound around the tube, with the foot maintaining firm contact with the tube's outer surface. The horizontal limb of each 'L' fully covers the base tube's surface, ensuring comprehensive protection. The tension in the fin strip during wrapping ensures that the fin foot is seated with forceful precision, keeping the fin securely in place. This tubing promises exceptional heat transfer capabilities, even at lower operating temperatures. The distinctive L-shaped design firmly anchors fins to withstand heat cycling and high-velocity air vibrations. Additionally, this fin design offers a degree of atmospheric protection, shielding the tube wall from corrosion. The expansive contact surface between the tube and finning elevates heat transfer efficiency. This innovative fin design combines high efficiency with cost-effectiveness, making it a superior choice.

To ensure durability, the fin ends are stapled to prevent unwinding, maintaining seamless contact between the fin foot and the tube. The contact point here is absolutely crucial in the seamless operation of the air cooler. This is where the magic of thermal transfer happens — from the tube wall, traversing through the finely crafted fin, and finally dissipating into the surrounding ambient air.

Advantages:

Perfectly tailored for low-temperature applications, ensuring efficiency and reliability.

The finning type triumphs as the most cost-effective solution when compared to other methods, making it an economically savvy choice.

Even if fins fail during production, they can be effortlessly removed, allowing the bare tube to be refitted with fresh finning, minimizing waste.

There's no requirement to form a helical groove over the core tube, simplifying the process significantly.

Fins can be effortlessly placed on an exceptionally thin-walled tube, which is especially advantageous when utilizing costly alloys as the core tube.

The tube confidently endures temperatures soaring up to 130°C, all while warding off atmospheric corrosion and eliminating thermal stress risks.

Application:

Highly suitable for oil and gas refineries, optimizing performance and efficiency.

An excellent choice for the petroleum, chemical, and petrochemical industries, ensuring robust application.

Perfectly designed for natural gas treatment processes, boosting operational excellence.

An integral component in the steel-making industry, enhancing production capabilities.

Ideal for power plants, contributing to improved energy output and stability.

A prime choice for air conditioning systems, offering enhanced cooling efficiency.

Revolutionizing compressor coolers with its unparalleled fin tube technology.

KL Footed Fin / Knurled L Footed Fin

The renowned KL fin is also identified as the knurled L fin, offering versatility and dependability. This innovative finned tube is nearly a twin to the Wrap-On fin and is crafted utilizing both Wrap-On and Embedded techniques, ensuring superior performance. The fins are ingeniously fashioned from strips prepared into an L shape, akin to the L type, then skillfully rolled into a taper that induces curling. Subsequently, it's helically wound onto the tube in an unbroken loop under tension, ensuring a snug fit. The fin embraces the tube intimately, creating a seamless union. A specialized spinning tool knurls the base tube, allowing the foot of the fin to integrate into the knurling, securing a tight bond and enhancing thermal performance.

The foot of one fin seamlessly meets the next if the appropriate fin strip is used, leaving no gaps between fins. This design inherently shields the tube from corrosion, extending longevity. In a fashion similar to L fins, the fins are secured at each end to avert unwinding, ensuring stability. KL -Foot tension wound finned tubes are predominantly employed in metal-related applications, offering unmatched performance. Capable of withstanding up to an impressive 320°C (608°F) maximum operating temperature, ensuring durability.

Advantages:

Tubes resistant to corrosion, offering reliability and longevity.

Boasts exceptional vibration resistance, maintaining performance integrity.

Engineered to endure temperatures as high as 320°C (608°F), showcasing robust thermal resilience.

Combines high thermal performance with stress resistance and air corrosion protection, forming an unparalleled trifecta of attributes.

KL finned tubes offer versatility, capable of replacing any type of finned tube with ease.

LL-Foot Fin / Overlapped L

Crafted from strips in a manner similar to the L type, the fin's foot is intricately shaped into a carefully controlled stepped double L form, rolled to curl gracefully. The LL-Foot Fin - Overlapped L is then expertly coiled helically onto the tube under tension, ensuring a perfect embrace. The fin securely grips the tube, with each fin overhanging the foot of the next, ensuring complete coverage of the base tube. This meticulous design effectively protects the tube from corrosion, extending its lifespan and reliability. In corrosive environments, the G Type Fin Tube Embedded Finned Tube emerges as a cost-effective alternative to the pricier extruded fin type. Its robust design ensures reliable performance, making it an excellent choice for challenging conditions.

The fins are meticulously secured at each end, utilizing the same trusted method as L fins. This ensures a tight and enduring fit, contributing to the longevity and efficiency of the tube. The LL-type fin tube is engineered to withstand temperatures up to a remarkable 350 degrees Fahrenheit (177 degrees Celsius), offering outstanding thermal efficiency and resilience in high-temperature applications.
