Cangzhou Datang Steel Pipe Co., Ltd. presents a diverse array of finned tubes tailored for excellence: tension wound finned tubes, embedded finned tubes, and extruded finned tubes.
Tension wound finned tubes are masterfully crafted by winding a precision strip made from aluminium or copper around the tube, utilizing tension to achieve superior structural integrity. Our advanced strip winding technology offers a variety of fin types to meet your needs: L-Fin, LL-Fin, and KL-Fin.
Embedded fins (G-Fins) are engineered through an intricate process of winding aluminium or copper strip into a meticulously machined helical groove on the tube's outer surface.
These three innovative finned tube categories-tension wound, embedded, and extruded-are quintessential for air cooler systems, catering to a broad range of applications:
Efficient heat exchangers for power plants, including electric, nuclear, thermal, and geothermal stations.
High-performance steam condensate systems.
Applications within the dynamic chemical and petrochemical industry.
Vital for food processing plants and cutting-edge refrigeration technology.
Employed within diverse industrial sectors such as steel mills, incinerators, and gas compression facilities.
L-Foot Finned Tube
This highly efficient and cost-effective L-footed finned tubing offers exceptional heat transfer capabilities even at reduced temperatures. The ingeniously designed L-shape ensures fins are held firmly, enduring heat cycling and high-velocity air vibrations with ease.
The L-Foot Finned Tube can be customized with the following fin variations:
Knurled Fin - Features an interference fit type fin with mechanical knurling, securing the fin material to the tube wall surface.
LL Fin - The double overlap fin, or 'double LL,' offers comprehensive double strip thickness coverage across the base tube.
Perforated L Fin - This fin design incorporates 'tear drop' slits along the helix, promoting efficient disruption of air flow for enhanced performance.
L-Foot Fin / Wrap-On Fin
L-Foot Tension Wound Finned Tubes also known as Wrap-On Finned Tubes, are perfect for applications with temperatures below 300 degrees Fahrenheit, offering protective benefits to the tube wall. These tubes feature a thin aluminium fin strip wound helically around the tube, ensuring robust construction and thermal efficiency. A 'foot' is ingeniously formed on one side of the fin strip, creating a distinctive L-Foot design. The fin strip is deftly wound around the tube, with the foot bearing firmly on the tube's outer surface for secure attachment. Each short horizontal limb of the L-Foot is in full contact with the tube surface, ensuring comprehensive coverage and protection. The fin strip's tension during wrapping ensures the fin foot is securely pressed against the tube, maintaining strong adherence. L-footed finned tubing delivers optimal heat transfer, especially at lower temperatures, due to its innovative design. The L-shaped design's rigidity ensures stability under intense conditions like heat cycling and high-velocity airflows. This fin type provides significant atmospheric protection to the tube wall, safeguarding it from potential corrosion. The extensive contact area between the tube and finning enhances heat transfer, maximizing thermal efficiency. Renowned for its efficiency, this fin design offers superior performance while remaining cost-effective.
Fin ends are meticulously stapled to prevent the unravelling of the aluminium fin, ensuring persistent contact between the fin foot and the tube. This component plays a pivotal role in the air cooler's functionality by facilitating efficient heat transfer. The process involves transferring heat from the tube wall, through the fin, and then dissipating it to the ambient air efficiently.
Advantages:
Perfectly suited for low-temperature applications, ensuring optimal performance in the most challenging conditions.
This finning type stands out as the most budget-friendly method compared to other available options, providing exceptional value.
Easily replaceable failed fins during production, with the added benefit of reusing the bare tube for finning anew.
No requirement for creating a helical groove on the core tube, simplifying the manufacturing process significantly.
Fins can be placed on a very thin-walled tube, which is especially desirable when using costly alloys as the core tube, maximizing material efficiency.
The tube is designed to endure temperatures up to 130°C, without risking atmospheric corrosion or thermal stress, ensuring durability and longevity.
Application:
Ideal for use in oil and gas refineries, enhancing cooling efficiency.
Widely applicable in the petroleum, chemical, and petrochemical industries, meeting their rigorous demands.
Essential for natural gas treatment processes, providing reliable performance.
Crucial for the steel-making industry, supporting efficient operations.
Power plants benefit greatly, optimizing their cooling systems for better productivity.
Perfect for air conditioning applications, ensuring efficient temperature regulation.
Compressor coolers benefit from its application, enhancing cooling efficiency.
KL Footed Fin / Knurled L Footed Fin
The KL fin also known as the knurled L fin, offers superior performance and reliability. This finned tube shares similarities with the Wrap-On fin, crafted using both Wrap-On and Embedded techniques for enhanced performance. Fins are crafted from strips shaped into an L configuration, then rolled into a taper to curl. Subsequently, it is helically wound onto the tube in a continuous loop under precise tension. The fin embraces the tube securely, ensuring maximum heat transfer efficiency. A spinning tool knurls the base tube, allowing the fin's foot to knurl into the base tube's knurling, creating a tight bond for improved thermal performance.
When the appropriate fin strip is used, the foot of one fin aligns perfectly against the next, eliminating spaces. This alignment effectively protects the tube from corrosion, extending its lifespan. Much like L fins, the fins are secured at each end to prevent unwinding, ensuring reliability. KL-Foot tension wound finned tubes are predominantly employed in metal applications for their superior performance. Can operate at a maximum temperature of up to 320°C (608°F), providing exceptional thermal capability.
Advantages:
Corrosion-resistant tubes offer unparalleled protection and durability.
Remarkable vibration resistance adds to the system's robustness and reliability.
Capable of withstanding high temperatures up to 320°C (608°F), ensuring consistent performance.
Combining high thermal performance, stress resistance, and air corrosion protection creates a unique offering.
KL fins can seamlessly replace any finned tube type, offering flexibility and convenience.
LL-Foot Fin / Overlapped L
Crafted from strips similarly to L type fins, but with a meticulously controlled double L shape for enhanced performance. The LL-Foot Fin - Overlapped L is precisely helically coiled onto the tube under tension for maximum adherence. The fin grips the tube tightly, with one fin's foot overlapping the next, ensuring total coverage. This configuration ensures comprehensive protection against corrosion, enhancing longevity. In corrosive environments, this tube serves as a cost-effective alternative to more expensive extruded fin types.
The fins are meticulously secured at each end following the same robust methodology as utilized in L fins, ensuring superior stability and performance. The innovative LL-type fin tube is expertly designed to withstand temperatures soaring up to an impressive 350 degrees Fahrenheit (177C), making it an ideal choice for high-temperature applications.
