Product Description

Product Parameters

Cangzhou Datang Steel Pipe Co., Ltd. presents a versatile range of finned tubes, including tension wound, embedded, and extruded varieties, each offering exceptional performance for diverse applications.

 

Tension wound finned tubes are expertly crafted by tightly winding an aluminum or copper strip around the tube, utilizing tension to secure the strip firmly in place. Our advanced strip winding technology allows for the creation of multiple fin types, such as L-Fin, LL-Fin, and KL-Fin, each tailored to optimize thermal performance.

 

Embedded fins (G-Fins) are ingeniously engineered by embedding an aluminum or copper strip into a precisely machined helical groove on the tube's exterior surface.
 

Our range of tension wound, embedded, and extruded finned tubes serves as the cornerstone for air coolers, applicable across various sectors:

 

Heat exchangers in power plants, including electric, nuclear, thermal, and geothermal facilities.

Efficient steam condensate systems.

Chemical and petrochemical industries, ensuring optimal performance.

Innovation in food processing plants and cutting-edge refrigeration technology.

Broad industrial applications, including steel mills, incinerators, and gas compression facilities.

 

L-Foot Finned Tube

 

Our L-footed finned tubes are engineered for peak efficiency and cost-effectiveness, facilitating maximum heat transfer even at reduced temperatures. The distinctive L-shape design steadfastly holds fins, capable of withstanding rigorous heat cycling and high-velocity air vibrations.

We offer L-Foot Finned Tubes with innovative fin variations:

 

Knurled Fin - Features an interference fit with mechanical knurling, firmly bonding the fin material to the tube wall surface.

LL Fin - The double overlap fin, also known as double LL, provides enhanced coverage with double strip thickness on the entire base tube.

Perforated L Fin - Innovatively designed 'tear drop' slits along the helix, effectively disrupting airflow for greater efficiency.

 

L-Foot Fin / Wrap-On Fin

L-Foot Tension Wound Finned Tubes also recognized as Wrap-On Finned Tubes, are ideal for applications where temperatures remain below 300°F, offering moderate tube wall protection. L-Foot tension wound finned tubes feature a delicate aluminum fin strip, meticulously wound around the tube in a helical pattern. An 'L-shape foot' is prefabricated on one side of the fin strip, lending the name L-Foot. This strip is meticulously wrapped around the tube, with the foot in constant contact with the outer surface. The short horizontal limb of each L is tightly pressed against the base tube surface, ensuring full coverage. The tension in the fin strip during wrapping secures the fin foot forcefully to the tube, maintaining the fin's stability. Our L-footed finned tubing is designed to maximize heat transfer, even at lower temperatures, setting a new standard in efficiency. The robust L-shaped design ensures that fins remain secure, capable of enduring both heat cycling and high-velocity air. This fin offers reliable atmospheric protection, safeguarding the tube wall against potential corrosion. The significant contact area between the tube and fin enhances thermal conductivity, optimizing heat transfer. This innovative fin design not only excels in efficiency but also proves to be economical.

 

Fin ends are meticulously stapled to prevent unraveling, preserving the vital contact between the fin foot and tube. This component plays a pivotal role in the air cooler's operation, facilitating the seamless transfer of heat from the tube wall, through the fin, and into the ambient air enveloping it.

 

Advantages:

Ideal for applications in low-temperature environments, ensuring optimal performance.

This finning type stands as the most cost-effective method available, providing superior value compared to alternative options.

Easily replace failed fins during production, allowing the bare tube to be reused for finning, enhancing efficiency and reducing waste.

No need to create a helical groove on the core tube, simplifying the production process and reducing labor costs.

Fin placement on incredibly thin-walled tubes is possible-especially beneficial when using costly alloys as the core tube.

Withstands temperatures up to 130°C, safeguarding against atmospheric corrosion and thermal stress, ensuring longevity.

 

Application:

Ideal for use in oil and gas refineries, offering robust solutions to complex cooling needs.

Petroleum, chemical, and petrochemical industries rely on its efficient performance.

Highly effective in natural gas treatment processes, ensuring seamless operations.

An essential component in the steel-making industry, enhancing production processes.

Power plants benefit from its reliability and efficiency, maintaining optimal operational standards.

Perfectly suited for air conditioning systems, improving energy efficiency and performance.

Compressor coolers: Enhances cooling efficacy in compressor systems, boosting efficiency.

KL Footed Fin / Knurled L Footed Fin:

The KL fin, also known as the knurled L fin, represents innovation in finned tube technology. This finned tube shares remarkable similarities with the Wrap-On fin and is crafted using both Wrap-On and Embedded techniques for optimized performance. Crafted from L-shaped strips, then rolled into a taper, these fins curl beautifully, ready for application. Helically wound onto the tube in a continuous loop under tension, these fins offer unmatched stability. The tube is lovingly embraced by the fin, enhancing thermal contact and efficiency. A specialized spinning tool knurls the base tube, integrating the fin's foot into the base tube's knurling for a tight bond and superior thermal performance.

 

Correct fin strip utilization prevents gaps, as each fin foot meets the next, enhancing corrosion protection. This configuration provides exceptional protection against corrosion, preserving the tube's integrity. Much like L fins, these are firmly attached at each end, preventing unwinding and maintaining structural integrity. KL-Foot tension wound finned tubes are typically utilized in metal applications, ensuring excellence and durability. Handles up to 320°C (608°F) maximum operating temperature, ensuring performance under extreme conditions.

Advantages:

Corrosion-resistant Tubes guarantee longevity even in harsh environments.

Engineered for vibration resistance, maintaining operational stability.

This resilient tube withstands temperatures soaring up to 320°C (608°F), maintaining efficiency.

An unprecedented combination: High thermal performance, stress resistance, and air corrosion protection.

KL can seamlessly replace any existing finned tube type, offering versatility and adaptability.
 

LL-Foot Fin / Overlapped L:

 

Crafted from strips similar to L type, the foot forms a double L shape, rolling into a taper for optimal fin orientation. The LL-Foot Fin - Overlapped L is helically wound onto a tube under tension, ensuring a snug fit. Fin clings to the tube, with each fin overlapping the next, ensuring comprehensive tube coverage. This comprehensive design offers superior protection against corrosion, preserving the tube's functionality. In corrosive environments, this tube type serves as an excellent alternative to more costly extruded fin types, delivering cost-effectiveness without compromising quality.

 

Our innovative fins are expertly secured at each end, mirroring the reliability and precision of L fins, ensuring optimal performance and durability. The robust LL-type fin tube is engineered to withstand temperatures soaring up to 350 degrees Fahrenheit (177°C), making it an exceptional choice for high-temperature applications.
