At Cangzhou Datang Steel Pipe Co., Ltd., we proudly offer a premium selection of finned tubes tailored to meet various industrial needs: tension wound finned tubes, embedded finned tubes, and extruded finned tubes. These are engineered to perfection to ensure reliability and efficiency in diverse applications.
Tension wound finned tubes are expertly crafted by wrapping a strip, made either of aluminum or copper, around the tube under precise tension. This process ensures a secure fit and optimal performance. Our advanced strip winding technology allows for the creation of distinct fin types, including L-Fin, LL-Fin, and KL-Fin, each designed to cater to specific thermal requirements.
Embedded fins (G-Fins) are meticulously crafted by embedding aluminum or copper strips into a helical groove, skillfully machined on the tube's outer surface. This technique ensures a robust and efficient thermal interface.
Our tension wound, embedded, and extruded finned tubes are pivotal components in air coolers, serving crucial roles across various industries. The primary application fields include:
Heat exchangers for power plants, spanning across electric, nuclear, thermal, and geothermal sectors, harness our finned tubes for superior thermal management.
Steam condensate systems benefit from enhanced efficiency and reliability with our specialized finned tubes.
Chemical and petrochemical industries rely on our finned solutions for optimized heat exchange processes.
Food processing plants and refrigeration technology sectors utilize our products for maintaining precise temperature controls and efficiency.
Our finned tubes are integral in industrial applications, including steel mills, incinerators, and gas compression facilities, delivering performance and durability.
L-Foot Finned Tube
With unmatched efficiency and cost-effectiveness, L-footed finned tubing is crafted for maximum heat transfer, specifically at lower temperature ranges. It stands as a formidable choice for various cooling challenges. The innovative L-shaped design offers unparalleled rigidity, ensuring stability against heat cycling and high-velocity air vibrations.
Enhance your systems with the L-Foot Finned Tube, available in various sophisticated Fin variations:
Knurled Fin - This fin type features a mechanically knurled interference fit, ensuring a robust connection between the fin material and the tube wall for maximum efficiency.
LL Fin - The Double Overlap fin, known as the double LL, provides an enhanced coverage with two layers of fin strip, ensuring thorough protection of the base tube.
Perforated L Fin - Designed with 'tear drop' slits strategically placed around the helix, this variation effectively disrupts airflow for superior thermal performance.
L-Foot Fin / Wrap-On Fin
L-Foot Tension Wound Finned Tubes also referred to as Wrap-On Finned Tubes, are ideal for applications with temperatures below 300 degrees Fahrenheit. These tubes offer essential wall protection in low-temperature environments. The L-Foot tension wound finned tubes are constructed by tightly helically winding a thin aluminum fin strip around the tube, ensuring a secure and efficient fit. A 'foot' is precisely formed on one side of the fin strip, giving rise to the name L-Foot. The strip is meticulously wound around the tube, with the foot making firm contact with the tube's outer surface, guaranteeing stability and performance. The short horizontal limb of each L ensures full contact with the base-tube surface, optimizing heat transfer. The inherent tension in the fin strip during wrapping ensures the fin foot is firmly seated on the tube, maintaining a consistent and reliable connection. L-footed finned tubing excels in providing maximum heat transfer efficiency at lower temperatures, making it an ideal choice for various cooling applications. The robust L-shaped design ensures that fins remain stable, resisting the effects of heat cycling and high-velocity air vibrations. This fin design not only enhances heat transfer but also offers a degree of atmospheric protection against tube wall corrosion. The broad contact surface between the tube and finning maximizes heat transfer efficiency, setting new standards in performance. Our L-footed fin design is a pinnacle of efficiency and cost-effectiveness, engineered to deliver unparalleled thermal performance.
Fins are securely stapled at the ends to prevent unraveling, ensuring enduring contact between the fin foot and the tube for sustained performance. This essential contact is vital to the seamless operation of the air cooler, as the heat is effectively transferred from the tube wall, through the meticulously crafted fin, and into the surrounding ambient air.
Advantages:
Ideal for low-temperature applications where efficiency is paramount.
The finning type stands as the most cost-effective method when compared to others, ensuring optimal investment value.
In production, any failed fins can be effortlessly removed, allowing the bare tube to be reused for finning, thus saving resources.
No requirement for creating a helical groove over the core tube, simplifying the process.
Fins can be applied to a very thin-walled tube, particularly beneficial when using costly alloys as the core tube, maximizing material efficiency.
The tube can endure temperatures up to an impressive 130°C without the risk of atmospheric corrosion or thermal stress, ensuring durability and longevity.
Application:
Oil and gas refineries, where reliability is a must.
Petroleum, chemical, and petrochemical industries seeking enhanced thermal performance.
Natural gas treatment, benefiting from improved efficiency.
Steel making industry, demanding robust performance.
Power plants requiring consistent and reliable cooling solutions.
Air conditioning systems that need efficient heat transfer.
Compressor coolers, where cooling performance is critical.
KL Footed Fin / Knurled L Footed Fin
The KL fin is also recognized as the knurled L fin, renowned for its superior thermal performance. This finned tube is almost identical to the Wrap-On fin and is crafted using a combination of Wrap-On and Embedded techniques for enhanced effectiveness. The fins are meticulously made from strips shaped into an L configuration comparable to the L type, then rolled into a taper that elegantly curls. The fin is then helically wound onto the tube in a continuous, tensioned loop. The tube is securely embraced by the fin, ensuring firm attachment. A spinning tool precisely knurls the base tube, seamlessly integrating the fin's foot into the knurling of the base tube for a tight bond and superior thermal performance.
The foot of one fin consistently aligns with the next when using the correct fin strip, leaving no space between the fins. This meticulous design protects the tube from potential corrosion. Much like L fins, the fins are securely attached at each end to prevent unwinding, maintaining integrity. In metal-related applications, KL-Foot tension wound finned tubes are typically the choice for their superior performance. Capable of withstanding a remarkable maximum operating temperature of up to 320°C (608°F).
Advantages:
Crafted with corrosion-resistant tubes for longevity.
Exceptional vibration resistance ensures stability and reliability.
Can withstand extreme temperatures of up to 320°C (608°F), ensuring high performance.
Combining high thermal performance and stress resistance with protection from air corrosion, this offers a truly unique combination.
KL fins are versatile and can replace any form of finned tube.
LL-Foot Fin / Overlapped L
The fins are expertly crafted from strips in a manner similar to the L type, where the foot is carefully shaped into a controlled double L configuration, rolled into a taper for curling. The LL-Foot Fin - Overlapped L is then helically coiled onto the tube under tension for a secure fit. The fin clings to the tube, with one fin elegantly overlapping the foot of the next, ensuring the base tube is completely covered. This secure design ensures the tube is well protected from corrosion. In corrosive environments, this tube is a popular alternative to the more costly extruded type fin, providing an economical solution.
Our innovative fins are meticulously secured at each end using the same robust method as L fins, ensuring optimal stability and performance. The advanced LL-type fin tube is engineered to withstand high temperatures, suitable for environments up to 350 degrees Fahrenheit (177°C), providing exceptional durability and reliability.
