At Cangzhou Datang Steel Pipe Co., Ltd., we proudly present a remarkable range of finned tubes to meet diverse needs: tension wound finned tubes, embedded finned tubes, and extruded finned tubes. Each type exemplifies our commitment to excellence and versatility.
Our tension wound finned tubes are engineered by skillfully winding a robust strip of either aluminium or copper around the tube under precise tension, ensuring superior performance and reliability. Our advanced strip winding technology artfully creates different fin types, including the L-Fin, LL-Fin, and KL-Fin, each tailored for specific performance needs.
Embedded fins (G-Fins) are innovatively crafted by embedding an aluminium or copper strip into a meticulously machined helical groove on the tube's outer surface, enhancing durability and thermal efficiency.
Our finned tubes, including tension wound, embedded, and extruded varieties, are pivotal devices for air coolers, finding applications in:
Heat exchangers serving power plants, encompassing electric, nuclear, thermal, and geothermal power domains.
Reliable steam condensate systems, designed for optimal performance.
Applications in the dynamic chemical and petrochemical industry, where efficiency is crucial.
Food processing plants and state-of-the-art refrigeration technology benefit from our solutions.
Industrial uses, including steel mills, incinerators, and gas compression facilities, leverage our robust technology.
L-Foot Finned Tube
The L-footed finned tubing is a marvel of efficiency and cost-effectiveness, providing unparalleled heat transfer capabilities at lower temperatures. Its unique L-shaped configuration ensures fins remain secure, enduring heat cycling and high-velocity air fluctuations with ease.
We offer the L-Foot Finned Tube in various innovative fin variations:
Knurled Fin - Featuring an interference fit type with mechanical knurling, ensuring a secure bond between the fin material and tube wall.
LL Fin - The double overlap fin design, known as double LL, provides comprehensive double strip thickness coverage over the entire base tube.
Perforated L Fin - This fin enhancement introduces 'tear drop' slits around the helix, effectively disrupting airflow for better performance.
L-Foot Fin / Wrap-On Fin
L-Foot Tension Wound Finned Tubes also called Wrap-On Finned Tubes, excel in applications with temperatures not exceeding 300°F, catering to low-temperature requirements while providing essential tube wall protection. These tubes feature a thin aluminium fin strip meticulously wound helically around the tube, ensuring consistent performance. An initial 'foot' is crafted on one side of the fin strip (hence the L-Foot name). The strip is skillfully wrapped around the tube, with the foot securely bearing on the tube's outer surface. The horizontal limb of each L contacts the base-tube surface, offering complete coverage and protection. Strip tension during wrapping firmly seats the fin foot on the tube, ensuring it remains securely in place. L-footed finned tubing excels in providing maximum heat transfer, especially at lower temperatures. Its distinctive L-shaped design ensures fins are held firmly, withstanding both heat cycling and high-velocity air vibrations. This fin offers a level of atmospheric protection to the tube wall against corrosion, enhancing longevity. A broad contact surface between the tube and finning significantly boosts heat transfer efficiency. This meticulously designed fin remains highly efficient and cost-effective, ensuring value and performance.
The precision-stapled fin ends prevent aluminium fin unraveling, maintaining secure contact between the fin foot and tube. The function of this contact is absolutely vital for the efficient performance of the air cooler, as it facilitates the transfer of heat seamlessly from the tube wall, through the fin, and out to the surrounding ambient air, ensuring optimal cooling efficiency.
Advantages of Our Product:
Perfectly engineered for applications in low-temperature environments
This type of finning is renowned for being the most cost-effective method among its peers, offering exceptional value.
In the event of fin failure, they can be effortlessly removed during production, allowing the bare tube to be reused for new finning, promoting sustainability and cost savings.
No necessity to craft a helical groove over the core tube, simplifying the production process.
The design allows for fin placement on a very thin-walled tube, which is particularly advantageous when employing costly alloys as the core tube, maximizing materials' efficiency.
Engineered to endure temperatures up to 130°C, these tubes are safeguarded against atmospheric corrosion and thermal stress, ensuring long-lasting reliability.
Wide Range of Applications Include:
Oil and gas refineries, where reliability and efficiency are paramount
Petroleum, chemical, and petrochemical industries, providing robust performance in critical environments
Natural gas treatment facilities, ensuring safe and efficient operations
Steel making industry, supporting high-temperature processes with ease
Power plants, contributing to the generation of energy through enhanced cooling
Air conditioning systems, delivering optimal cooling performance
Compressor coolers, ensuring efficient cooling in industrial applications
KL Footed Fin / Knurled L Footed Fin - An Overview
The KL fin design is alternatively referred to as the knurled L fin, showcasing its versatility. This finned tube closely resembles the Wrap-On fin and is crafted using both Wrap-On and Embedded techniques for enhanced performance. Crafted from strips prepared into an L shape akin to the L type, these fins are then skillfully rolled into a taper to create a curl. Subsequently, they are helically wound onto the tube in a seamless continuous loop under tension, ensuring a snug fit. The fin embraces the tube closely, optimizing thermal contact. A spinning tool meticulously knurls the base tube, and the foot of the fin is intricately knurled into the base tube, resulting in a secure bond and superior thermal performance.
The precision of the fin strip ensures that the foot of one fin meets the next without any gaps, enhancing protection. This design choice actively shields the tube from corrosion, prolonging its lifespan. Similar to L fins, the ends are firmly secured to prevent unwinding, maintaining structural integrity. KL -Foot tension wound finned tubes are predominantly employed in metal-related applications, thanks to their robust design. Capable of withstanding up to 320°C (608°F), these tubes perform exceptionally at higher temperatures.
Additional Advantages:
Corrosion-resistant tubes engineered for longevity
Outstanding vibration resistance ensuring stability in dynamic environments
Expertly designed to endure temperatures reaching up to 320°C (608°F) with ease.
The unique combination of high thermal performance, stress resistance, and protection from air corrosion makes this a standout choice.
KL finned tubes can seamlessly replace any existing form of finned tube, offering flexibility and improved performance.
LL-Foot Fin / Overlapped L - Technical Insight
These fins are crafted from strips using techniques similar to the L type, but with the foot meticulously prepared into a stepped double L shape, then crafted into a taper for optimal curling. The LL-Foot Fin is helically coiled onto the tube under tension, ensuring a perfect fit. The fin securely clings to the tube, with each fin overhanging the foot of the next, ensuring complete coverage of the base tube. This meticulous design provides excellent protection from corrosion, enhancing durability. In environments where corrosion is a concern, this remarkable tube design frequently serves as a cost-effective alternative to the pricier extruded type fin. Its reliability and efficiency make it a preferred choice in such demanding settings.
Ingeniously designed, the fins are securely fastened at each end, employing the same tried-and-tested method used for L fins, ensuring robustness and longevity. The LL-type fin tube proves to be an excellent choice for applications requiring heat resistance, withstanding temperatures soaring up to 350 degrees Fahrenheit (177°C), making it ideal for a wide range of thermal environments.
