At Cangzhou Datang Steel Pipe Co., Ltd., we present a diverse array of finned tubes designed to elevate your cooling systems to new heights. Explore our selection of 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 around the tube, ensuring a tight fit through expertly applied tension. Our strip winding technology allows us to offer various fin types, including the innovative L-Fin, the robust LL-Fin, and the versatile KL-Fin, each designed to meet diverse cooling requirements.
Embedded fins (G-Fins) Our embedded fins are created by winding superior aluminium or copper strip into a precisely engineered helical groove on the tube's outer surface, enhancing heat transfer efficiency.
Our finned tubes, including tension wound, embedded, and extruded varieties, are integral components in air coolers, serving crucial roles across various industries such as:
Heat exchangers in power plants, spanning sectors like electric, nuclear, thermal, and geothermal, benefit immensely from our finned tube technology.
Our tubes are pivotal in optimizing steam condensate systems, ensuring efficient energy conversion and management.
In the chemical and petrochemical industry, our finned tubes facilitate critical heat exchange processes, augmenting operational efficiency.
Food processing plants and refrigeration technology industries leverage our finned tubes for reliable temperature regulation and product safety.
Industrial applications, including steel mills, incinerators, and gas compression facilities, realize enhanced performance using our advanced finned tube solutions.
L-Foot Finned Tube
Our L-footed finned tubing is a marvel of efficiency and cost effectiveness, delivering unmatched heat transfer capabilities even at lower temperatures. The distinct L-shaped design ensures steadfast fin positioning, providing resilience against heat cycling and high velocity air vibrations.
We offer the L-Foot Finned Tube in a variety of fin styles to suit specific application needs:
Knurled Fin Featuring an interference fit, this fin employs mechanical knurling to achieve a secure bond between fin material and tube wall surface.
LL Fin Characterized by double overlap fin technology, the LL Fin offers comprehensive double strip thickness coverage across the base tube.
Perforated L Fin This fin enhances airflow disruption through 'tear drop' slits along the helix, optimizing heat dissipation.
L-Foot Fin / Wrap-On Fin
L-Foot Tension Wound Finned Tubes Also known as Wrap-On Finned Tubes, these are ideal for applications up to 300°F, ensuring low-temperature performance with essential tube wall protection. Crafted by helically winding a thin aluminium fin strip around the tube, the L-Foot tension wound design provides durability and efficient heat transfer. The ingenious 'foot' formation on the fin strip's side reinforces its connection to the tube, marking the signature of our L-Foot design. The fin strip is precisely wound around the tube, with the foot maintaining a secure position on the tube's outer surface. Each L's horizontal segment maintains full contact with the base-tube surface, ensuring complete and effective coverage. Fin strip tension during winding secures the fin foot forcefully onto the tube, providing a steadfast hold and lasting performance. Our L-footed finned tubing is designed for exceptional heat transfer efficiency, particularly at lower operating temperatures. Its unique L-shaped structure holds fin firmly, safeguarding against air vibrations and temperature fluctuations. This design also offers a protective barrier for the tube wall, shielding it from atmospheric corrosion effectively. The extensive contact surface between the tube and fins significantly boosts heat transfer, enhancing overall system performance. Our L-footed fin design strikes the perfect balance between high efficiency and cost-effectiveness, ideal for various industrial applications.
Fin ends are securely stapled to ensure the aluminium fin remains intact, preserving the vital contact between fin foot and tube. This contact is vital to the efficient operation of the air cooler, as it facilitates the seamless transfer of heat from the tube wall, through the fin, to the ambient air, ensuring optimal cooling performance.
Advantages:
Perfectly suited for applications involving low temperatures.
The finning type stands out as the most cost-effective solution among its counterparts.
With exceptional ease, failed fins can be removed during production, allowing the bare tube to be reused for finning.
No requirement exists to create a helical groove on the core tube.
Fins can be adeptly positioned on an ultra-thin-walled tube, which is particularly advantageous when employing costly alloys as the core tube.
The tube can comfortably endure temperatures up to 130°C, free from the perils of atmospheric corrosion or thermal stress.
Application:
Oil and gas refineries - Elevate your operations with enhanced cooling efficiency.
Petroleum, chemical, and petrochemical industries - Optimize your processes with superior heat management.
Natural gas treatment - Ensure reliability and performance.
Steel making industry - Achieve durable and consistent results.
Power plants - Maximize output and efficiency.
Air conditioning - Maintain perfect climates efficiently.
Compressor coolers - Ensure peak performance.
KL Footed Fin / Knurled L Footed Fin
The KL fin is alternatively termed the knurled L fin. This finned tube bears a strong resemblance to the Wrap-On fin, crafted using a blend of Wrap-On and Embedded techniques. The fins are meticulously shaped from strips into an L form, akin to the L type, then skillfully rolled into a taper to achieve a curl. Subsequently, it is helically wound onto the tube in an unbroken loop, maintained by tension. The tube experiences an embrace by the fin. A spinning tool creates knurling on the base tube, and the fin's foot is expertly knurled into this base, forging a robust bond and enhancing thermal efficiency.
The fin aligns snugly against its neighbor, ensuring no gaps when the correct fin strip is employed. This affords protection to the tube against corrosion. Similar to L fins, each end of the fins is secured to prevent unwinding. In metal applications, KL-Foot tension wound finned tubes are frequently utilized. Supports a maximum operating temperature of up to 320°C (608°F).
Advantages:
Corrosion-resistant Tubes - Offering unparalleled longevity.
Vibration resistance - Ensures stability in dynamic environments.
Engineered to endure temperatures as high as 320°C (608°F).
Boasting high thermal performance and stress resistance, coupled with air corrosion protection, it offers a truly unique combination.
KL finned tubes can seamlessly replace any finned tube type.
LL-Foot Fin / Overlapped L
The fins originate from strips, akin to the L type, but the foot is crafted into a precisely controlled stepped double L shape, rolled into a taper for curling. The LL-Foot Fin - Overlapped L is then helically coiled onto the tube under tension. The fin adheres closely to the tube, with one fin extending over to cover the foot of the adjacent fin, ensuring complete tube coverage. As a result, the tube enjoys comprehensive corrosion protection. In challenging corrosive environments, this particular form of tube emerges as a popular and cost-effective alternative to the pricier extruded type fin, offering robust durability and reliability.
The fins are meticulously secured at each end, employing the same trusted method as L fins, ensuring optimal performance and stability. The innovative LL-type fin tube is expertly designed to withstand temperatures soaring up to 350 degrees Fahrenheit (177 degrees Celsius), making it a resilient choice for high-temperature applications.
