Product Description

Product Parameters

Explore our diverse range of finned tubes: tension wound finned tubes, embedded finned tubes, and extruded finned tubes, each designed for superior performance.

Tension wound finned tubes masterfully crafted by winding an aluminium or copper strip around the tube under tension, ensuring robust structure and durability. Our strip winding technology delivers a spectrum of fin designs: L-Fin, LL-Fin, and KL-Fin, tailored for every need.

Introducing Embedded Fins (G-Fins) Created by winding an aluminium or copper strip into a precisely machined helical groove on the tube's outer surface, enhancing longevity and efficiency.

Our tension wound, embedded, and extruded finned tubes are vital components in air coolers, with broad applications in industries such as:

Heat exchangers serving electric, nuclear, thermal, and geothermal power plants.

Integrated solutions for steam condensate systems.

Key applications in the chemical and petrochemical industry.

Essential roles in food processing plants and cutting-edge refrigeration technology.

Critical functions in industrial environments including steel mills, incinerators, and gas compression facilities.

L-Foot Finned Tube

Our L-footed finned tubing optimizes heat transfer at reduced temperatures, combining efficiency with cost-effectiveness. The innovative L-shaped fin design maintains rigidity against heat cycling and high-velocity air vibrations, enhancing reliability.

Available in various Fin variations, the L-Foot Finned Tube offers tailored solutions:

Knurled Fin - Features an interference fit type fin with mechanical knurling, ensuring secure attachment to the tube wall surface.

LL Fin - Boasting Double Overlap fin coverage, the double LL provides enhanced strip thickness, fully covering the base tube.

Perforated L Fin - This enhancement introduces 'tear drop' slits along the helix, significantly disrupting air flow for improved efficiency.

L-Foot Fin / Wrap-On Fin

L-Foot Tension Wound Finned Tubes Also recognized as Wrap-On Finned Tubes, ideal for applications below 300°F, offering low-temperature solutions with protective benefits. Constructed with a helical wrap of thin aluminium fin strip, tightly encircling the tube circumference for optimal performance. A strategically formed 'foot' on one side of the fin strip lends its name, 'L-Foot,' ensuring secure placement. The fin strip is meticulously wound around the tube, with the foot in firm contact with the tube's outer surface for stability. Each L-shaped short limb contacts the base-tube surface, ensuring comprehensive coverage and protection. The tension during wrapping enforces fin foot seating and secures the fin firmly in place, enhancing performance. These L-footed finned tubes excel in maximizing heat transfer at lower temperatures, ensuring efficiency. The distinct L-shaped design keeps fins rigid, effectively managing heat cycling and high-velocity air vibration. This fin design imparts a level of atmospheric protection to the tube wall, guarding against corrosion. The expansive contact surface between tube and fin boosts heat transfer rates significantly. This highly efficient fin design balances performance with cost-effectiveness, meeting diverse application needs.

Fins are precisely stapled at the ends to prevent unravelling and maintain consistent contact between the fin foot and tube. This essential contact is vital to the functionality of the air cooler, as it facilitates the seamless transfer of heat from the tube wall, passing through the fin, to the ambient air surrounding it. This process is integral to maintaining optimal efficiency in heat exchange operations.

Advantages:

Expertly designed for low-temperature applications, ensuring reliability and effectiveness even in the most challenging conditions.

This finning type emerges as the most cost-effective method available, offering unparalleled value and performance compared to other alternatives.

In the event of fin failure, they can be effortlessly removed during production, allowing the bare tube to be reused for subsequent finning processes, enhancing sustainability and cost efficiency.

There is no necessity to craft a helical groove around the core tube, simplifying the production process and reducing potential complications.

Capable of accommodating fins on exceptionally thin-walled tubes, this feature is especially advantageous when utilizing expensive alloys as the core tube, optimizing material use without compromising strength or durability.

The robust design ensures that the tube withstands temperatures up to 130°C, mitigating risks of atmospheric corrosion or thermal stress, thereby extending its service life.

Application:

Oil and gas refineries

Petroleum, chemical, and petrochemical industries

Natural gas treatment

Steel making industry

Power plants

Air conditioning

Compressor coolers

KL Footed Fin / Knurled L Footed Fin

The KL fin is commonly referred to as the knurled L fin. This finned tube design closely resembles the Wrap-On fin, employing both Wrap-On and Embedded techniques to achieve exceptional performance. The fins are crafted from strips meticulously prepared into an L shape, akin to the L type, and subsequently rolled into a taper that induces curling. These are then helically wound onto the tube in a continuous loop under tension, ensuring a snug and secure fit. The fin wraps around the tube seamlessly, ensuring optimal thermal transfer and protection. A precision spinning tool knurls the base tube, allowing the foot of the fin to interlock with the knurling, forming a tight bond that enhances thermal performance significantly.

By employing the correct fin strip, the foot of each fin meets the next without gaps, creating a seamless barrier that enhances efficiency and prevents corrosion. This design feature effectively safeguards the tube from corrosion, ensuring durability and longevity. Similar to L fins, the fins are affixed at each end to prevent unwinding, maintaining structural integrity throughout its lifespan. Typically used in metal-related applications, KL-Foot tension wound finned tubes are renowned for their robustness and performance under demanding conditions. Up to 320°C (608°F) maximum operating temperature

Advantages:

Corrosion-resistant Tubes

Vibration resistance

Engineered to endure temperatures reaching up to 320°C (608°F), these tubes provide exceptional thermal resilience.

This unique combination of high thermal performance, stress resistance, and air corrosion protection delivers unparalleled efficiency.

KL fins are versatile replacements for any type of finned tube, offering flexibility and adaptation to various applications.

LL-Foot Fin / Overlapped L

Crafted from strips, these fins mirror the L type, with a precisely controlled stepped double L shape, rolled into a taper to facilitate curling. The LL-Foot Fin - Overlapped L is expertly coiled onto a tube under tension, ensuring a seamless fit. The fin securely envelops the tube, with each fin overhanging the foot of the next, fully covering the base tube for comprehensive protection against corrosion. This design offers superior corrosion protection, making it an excellent alternative to more costly extruded type fins, particularly in corrosive environments. In corrosive environments, this tube design is frequently chosen as a cost-effective alternative to the more expensive extruded type fin, ensuring both performance and economy.

Each end of the fin is securely fastened, employing the same reliable method used for L fins, ensuring maximum durability and efficiency. The robust LL-type fin tube is engineered to withstand temperatures soaring up to an impressive 350 degrees Fahrenheit (177 degrees Celsius), making it ideal for high-temperature applications.
