Product Description

Product Parameters

We proudly offer a diverse array of finned tubes designed for unmatched performance: tension wound finned tubes, embedded finned tubes, and extruded finned tubes.

 

Tension wound finned tubes are expertly crafted by winding an aluminium or copper strip meticulously around the tube under precise tension. Our advanced strip winding technology enables the creation of various fin designs: L-Fin, LL-Fin, and KL-Fin.

 

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

These tension wound finned tubes, embedded finned tubes, and extruded finned tubes serve as essential components for air coolers, with applications spanning diverse industries including:

 

Heat exchangers for power plants across all types - electric, nuclear, thermal, and geothermal power plants.

Efficient steam condensate systems.

The dynamic chemical and petrochemical industry.

Food processing plants and advanced refrigeration technology.

Industrial applications such as steel mills, incinerators, and gas compression facilities.

 

L-Foot Finned Tube

 

Our highly efficient yet economically viable L-footed finned tubing delivers optimal heat transfer at lower temperatures. The ingenious L-shaped design ensures fins remain securely in place, resisting the challenges of heat cycling and high-velocity air vibrations.

The L-Foot Finned Tube is available in the following innovative variations to further enhance performance:

 

Knurled Fin - A sophisticated interference fit type fin featuring mechanical knurling of the fin material to the tube wall surface, enhancing grip and efficiency.

LL Fin - Double Overlap fin (The double LL) offers a robust double strip thickness coverage of the entire base tube, maximizing durability.

Perforated L Fin - This enhancement incorporates 'tear drop' slits around the helix, ingeniously disrupting air flow for improved thermal performance.

 

L-Foot Fin / Wrap-On Fin

L-Foot Tension Wound Finned Tubes commonly referred to as Wrap-On Finned Tubes, are ideal for low-temperature applications where temperatures remain below approximately 300 degrees Fahrenheit and some degree of tube wall protection is essential. L-Foot tension wound finned tubes comprise a thin aluminium fin strip tightly wound in a helical pattern around the tube circumference. An 'L-foot' is skillfully formed on one side of the fin strip, lending the design its name. Subsequently, the strip is firmly wound around the tube, with the foot making secure contact with the tube's outer surface. The short horizontal limb of each L is in firm contact with the base-tube surface, ensuring complete coverage. Tension in the fin strip during wrapping firmly seats the fin foot on the tube, maintaining a robust and stable hold. This L-footed finned tubing is designed for maximum heat transfer efficacy at lower temperatures. Our unique L-shaped design provides remarkable stability, resisting the stresses of heat cycling and high-velocity air vibrations. This fin design inherently offers a degree of atmospheric protection to the tube wall, safeguarding against corrosion. The extensive contact surface between the tube and finning significantly boosts heat transfer efficiency. This remarkable fin design combines exceptional efficiency with cost-effectiveness.

 

To prevent unwinding, the ends of the fins are securely stapled, ensuring the aluminium fin retains its connection with the fin foot and the tube. This essential component is pivotal to the seamless operation of the air cooler, as the transfer of heat is intricately facilitated from the tube wall, across the fin, and into the encompassing ambient air, ensuring optimal cooling efficiency.

 

Advantages:

Engineered for exceptional performance in low-temperature environments

This finning type stands out as the most economical method available, offering top-notch efficiency at a fraction of the cost compared to alternative technologies.

Defective fins are effortlessly removable during production, allowing the bare tube to be readily refinned, ensuring sustainability and cost savings.

No helical groove is required on the core tube, simplifying the production process significantly.

Fins can be seamlessly placed on ultra-thin-walled tubes, an especially coveted feature when employing costly alloy materials as core tubes.

Designed to endure temperatures soaring up to 130°C, this tube shows remarkable resilience against atmospheric corrosion and thermal stress, ensuring longevity and reliability.

 

Application:

Refining oil and gas industries

Petroleum, chemical, and petrochemical sectors

Processing of natural gas

The steel manufacturing industry

Power generation facilities

Air conditioning systems

Compressor cooling solutions

KL Footed Fin / Knurled L Footed Fin

The KL fin is alternatively identified as the knurled L fin, reflecting its distinctive design. This finned tube closely parallels the Wrap-On fin, crafted utilizing both Wrap-On and Embedded methodologies. Fins are ingeniously crafted from strips transformed into an L shape, akin to the L type, then meticulously rolled into a taper that induces curling. Subsequently, it is helically wound around the tube in a continuous loop under precise tension. The fin snugly embraces the tube, ensuring a robust fit. Utilizing a spinning tool, the base tube is knurled, subsequently allowing the fin's foot to interlock with the base tube's knurling, forming a secure bond and enhanced thermal efficiency.

 

When the appropriate fin strip is employed, each fin's foot aligns seamlessly with the next, eliminating gaps between fins. This meticulous design aids in safeguarding the tube against corrosion. Similar to L fins, the fin ends are secured to prevent unwinding, ensuring durability. KL-Foot tension wound finned tubes are predominantly utilized in metal-related applications. Capable of withstanding extreme operating temperatures up to 320°C (608°F)

Advantages:

Tubes with superior corrosion resistance

Enhanced resistance to vibrations

Engineered to tolerate temperatures soaring up to 320°C (608°F).

A unique synergy of high thermal performance, stress resistance, and defense against air corrosion is achieved.

KL finned tubes are adaptable, serving as a direct replacement for any form of finned tube.
 

LL-Foot Fin / Overlapped L

 

Fins are fashioned from strips, akin to the L type, with a foot meticulously crafted into a precise stepped double L shape, rolled into a taper permitting curling. The LL-Foot Fin - Overlapped L is expertly coiled helically onto a tube under precise tension. The fin securely grips the tube, with each fin's foot overlapping the next, ensuring the base tube is entirely cloaked. This design impeccably shields the tube from corrosion, ensuring long-lasting performance. In environments where corrosion is a concern, our Robust G Type Embedded Finned Tube stands out as a highly economical alternative to the more costly extruded type fin tubes. Its design ensures exceptional performance and durability.

 

The fins are ingeniously secured at each end in a manner akin to the reliable L fins, ensuring steadfast functionality and longevity. The LL-type fin tube is engineered to withstand high temperatures, performing optimally at up to 350 degrees Fahrenheit (177 degrees Celsius), making it a versatile component in heat exchange applications.
