Product Description

Product Parameters

We proudly present a diverse range of finned tubes, each engineered for optimal performance: tension wound finned tubes, embedded finned tubes, and extruded finned tubes.

Tension wound finned tubes are meticulously crafted by wrapping a strip of premium aluminium or copper tightly around the tube, creating a robust bond under tension. Our cutting-edge strip winding technology allows for the creation of various fin types, including L-Fin, LL-Fin, and KL-Fin, each tailored to specific needs.

Embedded fins (G-Fins) are expertly manufactured by meticulously winding an aluminium or copper strip into precisely machined helical grooves on the tube's exterior.

Tension wound finned tubes, embedded finned tubes, and extruded finned tubes are quintessential components for air coolers, finding widespread application in the following sectors:

Heat exchangers for power plants, including electric, nuclear, thermal, and geothermal facilities.

Steam condensate systems, ensuring efficient thermal exchange.

Chemical and petrochemical industry, where reliability is paramount.

Food processing plants and cutting-edge refrigeration technology.

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

L-Foot Finned Tube

Maximize your operational efficiency with our L-footed finned tubing. This innovative solution offers superior heat transfer, even at lower temperatures, while remaining remarkably cost-effective. The distinct L-shaped design ensures that the fins are held firmly, adeptly withstanding both heat cycling and high-velocity air vibration.

Our L-Foot Finned Tube is available in several enhanced variations to suit diverse applications:

Knurled Fin - An ingenious interference fit type fin, featuring mechanical knurling that tightly secures the fin material to the tube wall surface.

LL Fin - The Double Overlap fin (the double LL) offers comprehensive double strip thickness coverage of the entire base tube.

Perforated L Fin - This modification adds unique 'tear drop' slits along the helix, effectively disrupting airflow for enhanced performance.

L-Foot Fin / Wrap-On Fin

L-Foot Tension Wound Finned Tubes also referred to as Wrap-On Finned Tubes, are an optimal choice for applications where temperatures are kept below approximately 300 degrees Fahrenheit, ensuring essential tube wall protection. These tubes are crafted by helically wrapping a thin aluminium fin strip tightly around the tube's circumference, ensuring precise assembly. A 'foot' is initially formed on one side of the fin strip, giving rise to the name L-Foot. The strip is then meticulously wound around the tube, with the foot establishing firm contact on the tube's outer surface. The short horizontal limb of each L makes full contact with the base-tube surface, ensuring complete coverage. The tension in the fin strip during wrapping exerts a forceful seating of the fin foot on the tube, maintaining a secure hold. L-footed finned tubing guarantees superior heat transfer capabilities even at reduced temperatures. The distinctive L-shaped configuration ensures robust fin retention, adeptly managing heat cycling and high-velocity air vibrations. This fin design also offers a considerable degree of atmospheric protection, safeguarding the tube wall from corrosion. The broad contact area between the tube and finning significantly amplifies heat transfer efficiency. Our fin design fuses high efficiency with cost-effectiveness, the perfect synergy for your needs.

Innovatively stapled fin ends prevent the unravelling of aluminium fins, ensuring sustained contact between the fin foot and tube for long-term reliability. This contact is the lifeline of air cooler operations, enabling the seamless transfer of heat from the tube wall, through the fin, and into the ambient air around. It’s where efficiency truly begins.

Advantages:

Ideal for low-temperature environments, this solution excels in delivering performance where it’s needed most.

This finning type stands out as the most economical choice among available methods, providing substantial cost savings.

Easily removable during production, failed fins allow the bare tube to be reused for finning, promoting sustainability and cost-efficiency.

Eliminates the need to carve a helical groove over the core tube, simplifying the process and reducing material stress.

Fins can be placed on ultra-thin-walled tubes, making it especially beneficial when using costly alloys as the core tube.

Capable of withstanding temperatures up to 130°C, this tube resists atmospheric corrosion and thermal stress, ensuring durability and reliability.

Application:

Oil and gas refineries

Petroleum, chemical, and petrochemical industries

Natural gas processing

Steel manufacturing sector

Power generation facilities

Air conditioning systems

Compressor cooling solutions

KL Footed Fin / Knurled L Footed Fin

The KL fin also known as the knurled L fin, offers unique enhancements to traditional designs. Mirroring the Wrap-On fin, this finned tube employs both Wrap-On and Embedded techniques to achieve superior performance. Crafted from strips shaped into an L comparable form, the fins are then rolled into a taper to curl around the tube. Wound helically onto the tube in a continuous loop, the fin remains tightly bound under tension. The fin embraces the tube, ensuring maximum heat exchange efficiency. Using a spinning tool, the base tube is knurled, allowing the fin’s foot to meld into the knurling for an unbreakable bond and enhanced thermal performance.

With the correct fin strip, each fin fits snugly against the next, leaving no gaps, and enhancing protective capabilities. This design shields the tube from corrosive elements, ensuring longevity and reliability. Attachment at each end mimics the L fin structure, preventing unwinding and ensuring stability during operation. Typically used in applications involving metals, KL-foot tension wound finned tubes offer unmatched reliability and efficiency. Engineered to operate at temperatures up to 320°C (608°F), it maintains performance under extreme conditions.

Advantages:

Corrosion-resistant Tubes

Vibration resistance

Withstands temperatures as high as 320°C (608°F), ensuring operational continuity in demanding scenarios.

Combining high thermal performance with stress resistance and air corrosion protection offers a unique, robust solution.

KL finned tubes can seamlessly replace any existing finned tube, providing a versatile upgrade path.

LL-Foot Fin / Overlapped L

Constructed from strips similar to the L-type, these fins feature a meticulously controlled stepped double L shape, enabling a secure curl. The LL-Foot Fin - Overlapped L is carefully helically coiled onto the tube, ensuring tightness and integrity. The fin grips the tube firmly, with each fin overhanging the foot of the next, providing complete coverage and protection. This configuration offers superior corrosion protection, making it a cost-effective alternative to pricier extruded fin types. In corrosive environments, this tube excels as a more economical substitute for the more expensive extruded fin type, offering dependable protection and performance.

Our cutting-edge fin tubes are meticulously secured at each end, utilizing the same reliable technique as our innovative L fins. This ensures unparalleled stability and performance. The robust LL-type fin tube is expertly engineered to withstand temperatures soaring up to a remarkable 350 degrees Fahrenheit (177°C), making it an ideal choice for high-temperature applications.
