Product Description

Product Parameters

Discover the versatility of our finned tubes designed to meet diverse needs: tension wound finned tubes, embedded finned tubes, and extruded finned tubes, each tailored for optimal performance.

Tension wound finned tubes are expertly crafted by winding a strip of premium aluminium or copper snugly around the tube, creating a high-performance product under tension. The strip winding technology unlocks a variety of fin styles, including the innovative L-Fin, LL-Fin, and KL-Fin, each offering unique benefits.

Embedded fins (G-Fins) are meticulously created by embedding aluminium or copper strip into a precisely machined helical groove on the tube's exterior for enhanced performance.

Our range of tension wound, embedded, and extruded finned tubes serve as essential components in air coolers, excelling in these common application fields:

Powerful heat exchangers serving electric, nuclear, thermal, and geothermal power plants, encompassing a wide array of energy solutions.

Reliable steam condensate systems tailored to optimize performance and efficiency in demanding environments.

Chemical and petrochemical industry applications, providing unparalleled solutions for complex processes.

Advanced food processing plants and state-of-the-art refrigeration technology, ensuring top-tier efficiency and reliability.

Industrial applications including steel mills, incinerators, and high-performance gas compression facilities.

L-Foot Finned Tube

Achieve peak efficiency with our cost-effective L-footed finned tubing, which delivers exceptional heat transfer at reduced temperatures. Ingeniously designed, the L-shaped configuration ensures fins remain secure against heat cycling and high-velocity air vibration.

The L-Foot Finned Tube can also be customized with the following distinct Fin variations:

Knurled Fin - A specialized interference fit type of fin, featuring mechanical knurling to enhance the bond between fin material and tube wall.

LL Fin - The Double Overlap fin, or double LL, provides comprehensive double strip thickness coverage over the entire base tube.

Perforated L Fin - Enhancements with tear drop-shaped slits along the helix, effectively disrupting airflow to boost performance.

L-Foot Fin / Wrap-On Fin

L-Foot Tension Wound Finned Tubes also known as Wrap-On Finned Tubes, ideal for applications where temperatures are below 300°F, providing essential tube wall protection and efficiency. L-Foot tension wound finned tubes are engineered from a fine aluminium fin strip, tightly coiled helically around the tube for superior performance. A distinctive "foot" is crafted on one side of the fin strip, giving rise to the term L-Foot, renowned for its functional design. The strip is expertly wound around the tube, with the foot securely pressing onto the tube's surface for optimal contact. Each L's short horizontal limb rests firmly against the base-tube surface, ensuring complete coverage and effective heat transfer. Tension in the wrapped fin strip guarantees the fin foot's firm seating on the tube, maintaining secure, lasting contact. Our L-footed finned tubing is crafted to deliver maximum heat transfer efficiently at lower operational temperatures. The exclusive L-shaped design ensures rigidity, enduring heat cycling, and withstanding fierce air vibrations. This design offers a reliable level of atmospheric protection against corrosion for the tube wall. The expansive contact area between the tube and finning significantly enhances heat transfer capabilities. This design strikes a perfect balance between high efficiency and cost-effectiveness, setting a benchmark in the industry.

The fin ends are securely stapled to prevent unraveling, ensuring that the fin foot maintains its strong bond with the tube. This contact is pivotal to the seamless functionality of the air cooler, as it ensures efficient heat transfer from the tube wall, through the fin, into the ambient air.

Key Advantages:

Perfectly tailored for low-temperature applications

The finning type emerges as the most cost-effective solution in contrast to other methods.

Failed fins can be effortlessly removed, allowing the bare tube to be reutilized for finning during production.

No helical groove is required over the core tube, simplifying the process.

Fins can be affixed to an ultra-thin-walled tube, particularly advantageous when costly alloys are employed as the core tube.

The tube is capable of enduring temperatures up to 130°C, safeguarding against atmospheric corrosion and thermal stress.

Wide Range of Applications:

Oil and gas refineries

Petroleum, chemical, and petrochemical industries

Treatment of natural gas

Steel manufacturing industry

Power generation plants

Air conditioning systems

Compressor coolers

KL Footed Fin / Knurled L Footed Fin

The KL fin, a marvel of engineering, is also known as the knurled L fin. This finned tube, akin to the Wrap-On fin, is crafted using both the Wrap-On and Embedded techniques. Fins are meticulously shaped into an L form, then elegantly rolled into a taper, allowing them to curl with precision. Subsequently, it is helically wound onto the tube in a continuous tensioned loop. The fin embraces the tube with a snug fit. A spinning tool intricately knurls the base tube, meshing the fin's foot into the knurling, achieving a firm bond and superior thermal performance.

When the correct fin strip is used, one fin foot precisely meets the next, leaving no gaps. This design effectively shields the tube from corrosion. Fins are securely attached at both ends, akin to L fins, to prevent unwinding. In metal applications, KL-Foot tension wound finned tubes are the preferred choice. Handles up to an impressive 320°C (608°F) in maximum operational temperature.

Standout Advantages:

Tubes resistant to corrosion

Remarkable vibration resistance

Capable of withstanding temperatures soaring up to 320°C (608°F).

A unique blend of exceptional thermal performance, stress resistance, and protection against air corrosion.

KL can seamlessly replace any form of finned tube.

LL-Foot Fin / Overlapped L

The fins are crafted from strips, similar to the L type, but with the foot expertly prepared into a distinct stepped double L shape, then tapered for curling. The LL-Foot Fin - Overlapped L is then helically coiled onto a tube with precision and tension. The fin firmly clings to the tube, with one fin gracefully overlapping the foot of the next, fully covering the base tube. This ensures the tube is thoroughly shielded from corrosion. In corrosive environments, this tube format is a cost-effective alternative to expensive extruded fin types.

Crafted with precision, the fins are meticulously secured at each end, employing the same robust technique used for L fins, ensuring optimal performance and durability. The LL-type fin tube, designed for superior resilience, is perfectly engineered to withstand temperatures of up to 350 degrees Fahrenheit (177C), making it an ideal choice for high-temperature applications.
