We offer a diverse range of finned tubes, each engineered for unique cooling requirements: tension wound finned tubes, embedded finned tubes, and extruded finned tubes.
Tension wound finned tubes are meticulously crafted by tightly winding a strip of premium aluminium or copper around the tube with precise tension. Our advanced strip winding technology enables the creation of various fin types: L-Fin, LL-Fin, and KL-Fin, each tailored for specific thermal dynamics.
Embedded fins (G-Fins), are expertly manufactured by intricately winding an aluminium or copper strip into a helical groove, precision-machined on the tube's outer surface.
Tension wound, embedded, and extruded finned tubes are quintessential components for air coolers, excelling in several applications:
Heat exchangers for power plants encompassing electric, nuclear, thermal, and geothermal facilities.
Efficient steam condensate systems.
Robust solutions for the chemical and petrochemical industries.
Innovative designs for food processing plants and state-of-the-art refrigeration technology.
Optimized for industrial use, including steel mills, incinerators, and gas compression facilities.
L-Foot Finned Tube
The L-footed finned tubing is a marvel of efficiency and cost-effectiveness, maximizing heat transfer at reduced temperatures. Its distinctive L-shaped architecture firmly secures fins, ensuring resilience against heat cycling and swift air vibrations.
Our L-Foot Finned Tube is available in the following innovative Fin variations:
Knurled Fin, - Featuring an interference fit with mechanical knurling, enhancing the bond between the fin material and the tube wall.
LL Fin, - Double Overlap fin (the double LL) offers comprehensive double strip thickness coverage over the base tube.
Perforated L Fin, - This dynamic enhancement introduces 'tear drop' slits around the helix, optimizing airflow disruption.
L-Foot Fin / Wrap-On Fin
L-Foot Tension Wound Finned Tubes, also referred to as Wrap-On Finned Tubes, are ideal for applications where temperatures do not surpass 300 degrees Fahrenheit, providing low-temperature solutions and necessary tube wall protection. L-Foot tension wound finned tubes feature finely wound thin aluminium fin strips, helically wrapped around the tube circumference with precision. An 'L-foot' is ingeniously formed on one side of the fin strip, thus giving it its distinctive name. The strip is then expertly wound around the tube, with the foot providing solid contact on the tube's outer surface. Each L's short horizontal limb is in full contact with the base-tube surface, ensuring comprehensive coverage. The tension in the fin strip as it encircles the tube ensures the fin foot is securely seated, maintaining firm placement. L-footed finned tubing promises exceptional heat transfer efficiency at lower temperatures. The innovative L-shaped design robustly holds fins, offering stability against heat cycling and high-velocity air vibration. This fin design also provides a layer of atmospheric protection against tube wall corrosion. The expansive contact surface between tube and finning significantly boosts heat transfer efficacy. This design offers a blend of high efficiency and economic viability.
Fins are stapled at the ends to prevent unraveling, maintaining crucial contact between the fin foot and the tube. This contact plays a pivotal role in the efficient operation of the air cooler, as it ensures the seamless transfer of heat from the tube wall, through the meticulously designed fin, and finally disperses it into the surrounding ambient air.
Advantages:
Perfectly tailored for low-temperature applications, providing reliable performance when you need it most.
This finning type is recognized as the most cost-effective solution when compared to alternative methods, offering unparalleled value.
During production, any failed fins can be effortlessly removed, allowing the bare tube to be reused for finning, ensuring sustainability and cost efficiency.
No need for creating a helical groove on the core tube, simplifying the process and reducing production complexities.
Fins can be placed on an exceptionally thin-walled tube, which is especially advantageous when utilizing expensive alloy materials as the core tube, optimizing material use and cost.
This tube can endure temperatures up to 130°C, ensuring resistance to atmospheric corrosion and eliminating risks associated with thermal stress.
Application:
Oil and gas refineries, providing crucial cooling solutions for energy sector efficiency.
Ideal for the petroleum, chemical, and petrochemical industries, enhancing operational processes.
Optimized for natural gas treatment, offering superior performance in energy applications.
Integral to the steel-making industry, ensuring process reliability and efficiency.
Power plants rely on these tubes for their robust cooling capabilities.
Perfectly suited for air conditioning systems, enhancing cooling efficiency.
Essential for compressor coolers, providing effective thermal management.
KL Footed Fin / Knurled L Footed Fin
The renowned KL fin is also known as the versatile knurled L fin. This finned tube closely resembles the Wrap-On fin, crafted using both Wrap-On and Embedded techniques for enhanced performance. Fins are engineered from strips meticulously shaped into an L form, akin to the L type, then rolled into a taper causing a natural curl. The fins are then helically wound onto the tube in a continuous loop under precise tension. The tube is snugly embraced by the fin, ensuring optimal heat transfer efficiency. A spinning tool expertly knurls the base tube, ensuring the foot of the fin is knurled into the base tube's knurling, resulting in a robust bond and superior thermal performance.
When the correct fin strip is used, the foot of one fin meets the next with no gaps, ensuring uniform coverage and protection. This seamless fin arrangement provides exceptional protection from corrosion, prolonging tube life. Similar to L fins, these fins are secure at each end to prevent unwinding, ensuring stability and reliability. In metal-related applications, KL-foot tension wound finned tubes are the preferred choice for their robust performance. Capable of withstanding maximum operating temperatures of up to 320°C (608°F), ensuring high performance under extreme conditions.
Advantages:
Corrosion-resistant Tubes, offering long-lasting and reliable protection in harsh environments.
Designed to resist vibration, ensuring stable and consistent operation.
With a remarkable ability to withstand temperatures reaching up to 320°C (608°F), these tubes ensure unwavering performance.
The combination of high thermal performance, stress resistance, and unparalleled air corrosion protection offers a unique and innovative solution.
Any form of finned tube can seamlessly be replaced with the advanced KL type, ensuring versatility and efficiency.
LL-Foot Fin / Overlapped L
Fins are fashioned from strips similarly to the L type, but with a foot meticulously crafted into a stepped double L shape, offering a controlled curl. The LL-Foot Fin – Overlapped L is then helically coiled onto a tube under maintained tension, ensuring a secure fit. The fin fully clings to the tube, with one fin overhanging the next, completely covering the base tube. The resulting protection ensures the tube is comprehensively shielded from corrosion, enhancing durability. In corrosive environments, this tube type is often used as a cost-effective alternative to the pricier extruded type fins.
In a manner akin to the L fins, the fins are expertly secured at each terminal point, ensuring robust and reliable performance. The cutting-edge LL-type fin tube is engineered to withstand temperatures soaring up to a remarkable 350 degrees Fahrenheit (177°C), making it ideal for high-temperature applications.
