At Cangzhou Datang Steel Pipe Co., Ltd., we proudly offer a variety of innovative finned tubes: tension wound finned tubes, embedded finned tubes, and extruded finned tubes, each tailored to enhance your air cooler applications.
Tension wound finned tubes are expertly crafted by wrapping a strip, made from either premium aluminium or copper, tightly around the tube under precise tension, ensuring exceptional performance. Our advanced strip winding technology offers diverse fin options: L-Fin, LL-Fin, and KL-Fin, catering to all your specific needs.
Embedded fins (G-Fins) are meticulously created by embedding an aluminium or copper strip into a helical groove precisely machined onto the outer surface of the tube, ensuring superior heat transfer efficiency.
Tension wound finned tubes, embedded finned tubes, and extruded finned tubes are the cornerstone devices for cutting-edge air coolers, with widespread applications in the following sectors:
Heat exchangers for power plants, including electric, nuclear, thermal, and geothermal facilities, ensuring optimal efficiency in power generation.
Steam condensate systems, providing reliable and efficient heat exchange solutions.
Chemical and petrochemical industry, where robust performance and durability are crucial.
Food processing plants and refrigeration technology, offering hygienic and efficient cooling solutions.
Industrial applications, such as steel mills, incinerators, and gas compression facilities, ensuring seamless operation and energy efficiency.
L-Foot Finned Tube
The L-footed finned tubing is a marvel of engineering, delivering maximum heat transfer efficiency at lower temperatures while being highly cost-effective. The ingenious L-shaped design secures the fins robustly, ensuring they withstand intense heat cycling and high-velocity air vibrations.
We offer the L-Foot Finned Tube in various fin modifications to suit diverse applications:
Knurled Fin - This fin features an interference fit with mechanical knurling of the fin material onto the tube wall, enhancing contact for superior heat exchange.
LL Fin - The Double Overlap fin (the double LL) delivers double strip thickness coverage over the entire base tube, maximizing heat transfer.
Perforated L Fin - Enhanced with 'tear drop' slits around the helix, this design disrupts airflow to improve heat dissipation.
L-Foot Fin / Wrap-On Fin
L-Foot Tension Wound Finned Tubes also known as Wrap-On Finned Tubes, are ideal for applications not exceeding 300 degrees Fahrenheit, providing essential tube wall protection in low-temperature environments. These tubes feature a slender aluminium fin strip, precisely helically wound around the tube circumference for optimal thermal performance. A 'foot' is initially formed on one side of the fin strip, giving rise to the name L-Foot. The strip is then wound tightly with the foot firmly bearing on the tube's outer surface, ensuring a secure fit. The short horizontal limb of each L ensures complete contact with the base-tube surface, enhancing thermal efficiency. Tension in the fin strip as it is wrapped ensures the fin foot seats forcefully on the tube, maintaining stability and performance. The L-footed finned tubing stands out for its maximum heat transfer capabilities at lower temperatures. The unique L-shaped design guarantees fins remain rigid and durable, withstanding harsh heat cycling and high-velocity air vibrations with ease. This fin design also provides a certain level of atmospheric protection for the tube wall, guarding against corrosion. The expansive contact surface between the tube and the finning significantly boosts heat transfer performance. This efficient fin design not only excels in performance but also offers cost-effective solutions for diverse applications.
To prevent the aluminium fin from unravelling, the ends are securely stapled, ensuring consistent contact between the fin foot and the tube. This component is vital for the optimal performance of air coolers, expertly transferring heat from the tube wall, through the meticulously designed fin, and out into the ambient air, ensuring efficient cooling.
Advantages:
Perfectly suited for low-temperature applications, ensuring versatility and reliability in diverse environments.
Offering unparalleled cost-effectiveness, this finning type is unmatched when compared to alternative methods.
Easily replaceable, failed fins can be efficiently removed during production, allowing the bare tube to be reused for finning, enhancing sustainability.
Eliminates the need to create a helical groove in the core tube, simplifying the manufacturing process.
Enables the placement of fins on ultra-thin-walled tubes, especially advantageous when utilizing high-value alloys as the core tube.
Engineered to endure temperatures up to 130°C, this tube is shielded against atmospheric corrosion and thermal stress.
Application:
Ideal for use in oil and gas refineries, delivering exceptional performance and reliability.
Widely applicable in petroleum, chemical, and petrochemical industries, meeting rigorous demands.
A preferred choice for natural gas treatment, ensuring efficiency and reliability.
Valuable for steel making industry applications, enhancing process efficiency.
Crucial for power plants, contributing to superior energy management.
Essential for air conditioning systems, promoting effective cooling.
Highly suitable for compressor coolers, ensuring optimal thermal management.
KL Footed Fin / Knurled L Footed Fin
The KL fin is also referred to as the knurled L fin, synonymous with durability and efficiency. This finned tube closely resembles the Wrap-On fin, crafted using both Wrap-On and Embedded techniques for enhanced performance. Expertly crafted, the fins are fashioned from strips into an L shape akin to the L type, then skillfully rolled into a taper causing them to curl. The fins are then helically wound onto the tube in a continuous loop under tension, ensuring secure attachment. The tube is enveloped by the fin, maximizing surface contact for superior heat transfer. With precision, a spinning tool knurls the base tube, seamlessly integrating the foot of the fin into the base tube's knurling, enhancing thermal performance.
When the correct fin strip is used, the foot of one fin seamlessly aligns with the next, leaving no gaps and ensuring comprehensive coverage. This innovative design helps protect the tube from corrosion, extending its lifespan. Similar to L fins, these fins are securely attached at each end, preventing any potential unwinding. Typically employed in metal-intensive applications, KL -Foot tension wound finned tubes are a reliable choice. Capable of operating at temperatures up to 320°C (608°F), ensuring robustness and adaptability.
Advantages:
Crafted with corrosion-resistant tubes, enhancing longevity and reliability.
Designed with exceptional vibration resistance, safeguarding structural integrity.
Capable of withstanding temperatures of up to 320°C (608°F), guaranteeing performance under extreme conditions.
Combining high thermal performance with resilience against stress and air corrosion, this product offers a truly unique solution.
Versatile KL fins can replace any form of finned tube, providing flexibility in application.
LL-Foot Fin / Overlapped L
Fins are meticulously created from strips, similar to the L type, with a carefully controlled double L shape, rolled into a taper for optimal performance. These LL-Foot Fins are expertly helically coiled onto a tube under tension, ensuring a snug fit. The fin firmly clings to the tube, with one fin elegantly overlapping the next, completely covering the base for superior corrosion protection. This design ensures comprehensive protection from corrosion, safeguarding the tube's integrity. In environments where corrosive elements are a concern, the Premium G Type Embedded Finned Tube emerges as a cost-effective alternative to the pricier extruded fin tubes, delivering exceptional durability and performance.
The robust design ensures that the fins are meticulously anchored at both ends, mirroring the secure attachment method of L fins, thereby guaranteeing long-lasting efficiency. Our LL-type fin tube is engineered to withstand high temperatures, comfortably operating at up to 350 degrees Fahrenheit (177 degrees Celsius), making it ideal for demanding thermal applications.
