Product Description

Product Parameters

Discover our exquisite range of finned tubes, designed for unparalleled performance: tension wound finned tubes, embedded finned tubes, and extruded finned tubes.

Tension wound finned tubes are ingeniously crafted by wrapping a strip of premium aluminium or copper around the tube, utilizing a tension technique that ensures utmost precision. Our advanced strip winding technology creates a variety of fin types tailored to specific needs: L-Fin, LL-Fin, and KL-Fin.

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

Central to air cooler operations, these finned tubes are vital in diverse applications, including:

Heat exchangers in power plants, be it electric, nuclear, thermal, or geothermal.

Steam condensate systems where efficiency meets reliability.

The chemical and petrochemical industry, ensuring optimal performance.

Transform food processing plants and refrigeration technology with superior heat exchange.

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

L-Foot Finned Tube

This innovative, cost-effective L-footed finned tubing delivers outstanding heat transfer even at low temperatures. Its distinctive L-shaped structure provides unmatched stability, enduring heat cycling and high-velocity air vibrations.

We also offer the L-Foot Finned Tube with these unique fin variations:

Knurled Fin - An interference-fit type with mechanical knurling that secures the fin material to the tube wall.

LL Fin - Features a double overlap design for comprehensive coverage and enhanced durability.

Perforated L Fin - Enhanced with 'tear drop' slits to disrupt airflow and boost efficiency.

L-Foot Fin / Wrap-On Fin

L-Foot Tension Wound Finned Tubes Ideal for applications under 300°F, these tubes offer reliable protection and are perfect for low-temperature settings. L-Foot tension wound finned tubes are crafted from a thin, precisely wound aluminium fin strip. The fin strip is sculpted with a 'foot', forming the L-Foot design. This strip is tightly wound, with the 'foot' securing itself firmly on the tube surface. The L's horizontal limb thoroughly covers the base-tube, ensuring complete protection. Tension during the wrapping ensures the fin foot is seated robustly, maintaining its position firmly. These L-footed tubes are engineered for maximum heat transfer, even at lower temperatures. The innovative L-shaped design withstands heat cycling and high-velocity air vibrations effortlessly. This design provides a degree of atmospheric shielding against corrosion for the tube wall. A broad surface contact between the tube and finning significantly boosts heat transfer efficiency. This intelligently designed fin offers high efficiency at a cost-effective price.

To ensure durability, fin ends are securely stapled, preventing unraveling and maintaining consistent contact between the fin foot and tube. This essential contact is the linchpin in the operation of air coolers, seamlessly transferring heat from the sturdy tube wall, through the efficient fin, and into the ambient air, making it indispensable for optimal performance.

Advantages:

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

This finning type stands out as the most cost-effective method, surpassing other alternatives in economic efficiency.

Failed fins are effortlessly removed during production, allowing the reuse of bare tubes for finning, reducing waste and costs.

No need for a helical groove on the core tube, simplifying the process and reducing production time.

Fins can be placed on exceptionally thin-walled tubes, particularly beneficial when utilizing expensive alloys for the core tube, offering cost savings and versatility.

Capable of withstanding temperatures up to 130°C without risking atmospheric corrosion or thermal stress, ensuring durability and longevity.

Application:

Vital for oil and gas refineries, enhancing cooling processes.

Crucial in petroleum, chemical, and petrochemical industries, boosting efficiency and productivity.

Integral to natural gas treatment, ensuring optimal processing.

Essential in the steel-making industry, supporting high-performance cooling needs.

Indispensable for power plants, optimizing cooling systems.

Perfect for advanced air conditioning systems, offering superior performance.

Ideal for compressor coolers, ensuring effective and reliable operation.

KL Footed Fin / Knurled L Footed Fin

The KL fin is widely recognized as the knurled L fin. This finned tube, nearly identical to the Wrap-On fin, is crafted using both Wrap-On and Embedded techniques, harmonizing the best of both worlds. The fins are expertly crafted from strips, shaped into an L form resembling the L type, then rolled into a taper that elegantly curls. Subsequently, it is helically wound onto the tube in a seamless continuous loop under precise tension. The fin embraces the tube snugly for enhanced connectivity. A spinning tool meticulously knurls the base tube, and then the fin's foot is knurled into the base tube's knurling, achieving a secure bond and enhanced thermal performance.

With the correct fin strip, fins interlock seamlessly, leaving no space between them, offering superior protection. This ingenious design shields the tube effectively against corrosion. In a manner akin to L fins, the fins are secured at each end, preventing unwinding and ensuring stability. KL -Foot tension wound finned tubes are typically employed in metal applications, demonstrating their versatility. Withstand an impressive maximum operating temperature of up to 320°C (608°F), ensuring performance in diverse environments.

Advantages:

Corrosion-resistant Tubes

Designed for exceptional vibration resistance, enhancing durability.

Withstands impressive temperatures up to 320°C (608°F), showcasing its strength.

Offers a remarkable combination of high thermal performance, stress resistance, and air corrosion protection, truly unique.

KL seamlessly replaces any form of finned tube, offering unmatched versatility.

LL-Foot Fin / Overlapped L

The fins, crafted from strips, mirror the L type but feature a meticulously controlled stepped double L shape, rolled into an artful taper for curling. The LL-Foot Fin - Overlapped L is then skillfully helical coiled onto a tube under calculated tension. This design securely envelops the tube, with each fin elegantly overhanging the foot of the subsequent fin, fully covering the base tube. This ingenious cladding ensures the tube is well-protected from corrosion. In corrosive environments, this tube type is a preferred alternative to the more costly extruded type fin, offering economic efficiency.

Our innovative fin design ensures that the fins are meticulously secured at each end, akin to the reliable L fins, providing robust stability and enhanced performance in demanding environments. Engineered for high-performance, the LL-type fin tube excels in operations withstanding temperatures soaring up to 350 degrees Fahrenheit (177°C), making it an ideal choice for challenging thermal applications.
