Product Description

Product Parameters

At Cangzhou Datang Steel Pipe Co., Ltd., we offer an exquisite array of finned tubes tailored for supreme performance: tension wound finned tubes, embedded finned tubes, and extruded finned tubes. Each type is crafted to meet diverse cooling needs and applications.

 

Tension wound finned tubes are masterpieces of engineering, crafted by elegantly wrapping a sleek strip of aluminium or copper around the tube with precision and tension, ensuring optimal heat transfer. Our strip winding technology showcases an array of fin types, including the meticulously crafted L-Fin, LL-Fin, and KL-Fin, each offering unique benefits for varied applications.

 

Embedded fins (G-Fins) These are crafted by intricately winding aluminium or copper strips into a helical groove, expertly machined on the outer surface of the tube, providing a robust and efficient solution.
 

Tension wound finned tubes, embedded finned tubes, and extruded finned tubes are pivotal components in air coolers. Their versatile applications span across diverse industries, including:

 

Heat exchangers for power plants, including electric, nuclear, thermal, and geothermal sectors, ensuring efficient energy management.

Advanced steam condensate systems that enhance efficiency and reliability.

Chemical and petrochemical industry, where precision and durability are paramount.

Food processing plants and cutting-edge refrigeration technology, maintaining safety and quality.

Industrial applications, including steel mills, incinerators, and gas compression facilities, benefiting from robust and reliable performance.

 

L-Foot Finned Tube

 

Remarkably efficient and cost-effective, the L-footed finned tubing ensures maximum heat transfer at lower temperatures, making it an ideal choice for numerous applications. With its distinctive L-shaped design, this finned tubing holds the fins steadfastly, expertly resisting heat cycling and high-velocity air vibration for enduring performance.

The L-Foot Finned Tube can be customized with the following fin variations:

 

Knurled Fin - This design features an interference fit type fin, where the fin material is mechanically knurled to the tube wall surface, enhancing grip and efficiency.

LL Fin - The Double Overlap fin (Double LL) design provides comprehensive double-strip thickness coverage, ensuring the entire base tube is protected and optimized for performance.

Perforated L Fin - This innovative enhancement creates 'tear drop' slits around the helix, disrupting airflow to enhance performance and heat dissipation.

 

L-Foot Fin / Wrap-On Fin

L-Foot Tension Wound Finned Tubes Known also as Wrap-On Finned Tubes, these are perfect for applications where temperatures remain below approximately 300°F, offering necessary tube wall protection for low-temperature settings. L-Foot tension wound finned tubes are ingeniously crafted with a thin aluminium fin strip, precisely wound helically around the tube circumference for maximum efficiency. A 'foot' is meticulously formed on one side of the fin strip, giving rise to the name 'L-Foot.' The strip is then tightly wound around the tube, with the foot in firm contact with the tube's exterior surface, ensuring stability and efficiency. The short horizontal limb of each L fully contacts the base-tube surface, providing comprehensive coverage and maximized heat transfer. Tension in the fin strip during wrapping ensures the fin foot seats forcefully on the tube, holding it securely in place for enhanced performance. L-footed finned tubing is designed to deliver superior heat transfer at lower temperatures, making it a cost-effective solution. Its unique L-shaped design steadfastly holds fins in place, effectively resisting both heat cycling and high-velocity air vibration. This fin design also offers a degree of atmospheric protection for the tube wall against corrosion, ensuring longevity. The extensive contact surface between the tube and finning is engineered to enhance heat transfer efficiency. Engineered for high efficiency and cost-effectiveness, this fin design is a testament to innovative engineering.

 

To maintain integrity, the ends of the fins are expertly stapled, preventing the unravelling of the aluminium fin and ensuring that contact between the fin foot and the tube is consistently maintained. This crucial contact within the air cooler plays a pivotal role, ensuring efficient heat transfer from the tube wall, through the fin, and ultimately dispersing into the surrounding ambient air seamlessly.

 

Advantages:

Perfectly adapted for low-temperature applications, ensuring reliable performance.

This finning type stands out as the most cost-effective method available, providing excellent value compared to alternatives.

Easily replace failed fins during production, allowing the bare tube to be reused, which optimizes resources and efficiency.

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

Fins can be applied to ultra-thin-walled tubes, a particularly desirable feature when utilizing costly alloys as core tubes, enhancing economic feasibility.

Capable of withstanding temperatures of up to 130°C, this tube ensures durability without succumbing to atmospheric corrosion or thermal stress.

 

Application:

Oil and gas refineries, providing essential cooling solutions.

Widely used within the petroleum, chemical, and petrochemical industries for optimal operational efficiency.

Ideal for natural gas treatment processes, enhancing system reliability.

Steel making industry, crucial for maintaining operational effectiveness.

Vital component in power plants, contributing to energy efficiency.

Air conditioning systems benefit from enhanced cooling capabilities.

Compressor coolers, ensuring efficient thermal management.

KL Footed Fin / Knurled L Footed Fin

The KL fin - also recognized as the knurled L fin - offers specialized performance. This finned tube, comparable to the Wrap-On version, is crafted using both Wrap-On and Embedded techniques to ensure optimal functionality. Designed with strips shaped into an L form, akin to the L type, it's rolled into a taper that naturally curls, enhancing fit and function. Fin is helically wound onto the tube in a continuous motion under tension, ensuring a secure and lasting bond. The fin snugly embraces the tube, optimizing thermal properties. A spinning tool intricately knurls the base tube, allowing the fin's foot to seamlessly integrate into the tube's knurling, enhancing bond strength and thermal efficiency.

 

When utilizing the correct fin strip, fins align perfectly with no gaps, offering continuous protection and performance. This meticulous construction aids in safeguarding the tube against corrosion, extending its life. Similar to L fins, they are securely attached at each end, preventing unwinding and ensuring structural integrity. KL-Foot tension wound finned tubes are particularly favored in metal-involving applications for their superior characteristics. These tubes operate efficiently up to a maximum temperature of 320°C (608°F), offering reliable performance.

Advantages:

Corrosion-resistant Tubes, ensuring longevity and reliability.

Designed for vibration resistance, providing stability under duress.

Endure temperatures up to 320°C (608°F), ensuring robust performance under thermal stress.

This unique combination of high thermal performance, stress resistance, and air corrosion protection is unmatched in the industry.

KL fins can seamlessly replace any other finned tube, offering versatile solutions.
 

LL-Foot Fin / Overlapped L

 

Crafted from strips in a manner analogous to the L type, with a foot formed into a precise stepped double L shape, enhancing efficacy. The LL-Foot Fin - Overlapped L is expertly helically coiled onto a tube under tension, ensuring a durable and secure fit. Fins cling firmly to the tube, with each fin overlapping the next, ensuring complete coverage and protection. This arrangement offers exceptional corrosion protection, maintaining the tube's integrity over time. In environments where corrosion is a concern, our G Type Fin Tube with Embedded Finned Tube stands out as an ideal alternative to the costly extruded type fin, offering exceptional durability and performance.

 

The fins are meticulously secured at each end, employing the same proven technique as used in L fins, ensuring steadfastness and efficiency in every application. Designed for reliability, the LL-type fin tube can withstand temperatures soaring up to 350 degrees Fahrenheit (177 degrees Celsius), making it an excellent choice for high-temperature applications.
