Product Description

Product Parameters

At Cangzhou Datang Steel Pipe Co., Ltd., we proudly present a comprehensive range of finned tubes to meet diverse industrial needs, including tension wound finned tubes, embedded finned tubes, and extruded finned tubes.

 

Our tension wound finned tubes are meticulously crafted by tightly winding a strip of premium aluminium or copper around the tube under precise tension, ensuring durability and efficiency. Our advanced strip winding technology enables the creation of various fin types, such as the highly efficient L-Fin, LL-Fin, and KL-Fin, each tailored for specific heat transfer applications.

 

Embedded fins (G-Fins) These fins are expertly manufactured by embedding an aluminium or copper strip into a helical groove precisely machined into the outer surface of the tube, ensuring superior thermal performance.
 

The tension wound, embedded, and extruded finned tubes are integral components in air cooler systems, serving vital roles across a myriad of sectors, including:

 

Heat exchangers for power plants, spanning electric, nuclear, thermal, and geothermal facilities, where efficient thermal management is crucial.

Steam condensate systems that demand reliable and sustained performance.

Chemical and petrochemical industry, where robust solutions are essential for handling diverse processes.

Food processing plants and advanced refrigeration technology, ensuring optimal temperature control and energy efficiency.

Various industrial applications, including steel mills, incinerators, and gas compression facilities, where high-performance cooling is required.

 

L-Foot Finned Tube

 

Our L-footed finned tubing stands as a paragon of efficiency and cost-effectiveness, delivering maximum heat transfer at lower operational temperatures. The innovative L-shaped design ensures the fins remain firmly in place, even under rigorous conditions of heat cycling and high-velocity air vibrations.

The L-Foot Finned Tube is available in several advanced variations, each designed to meet specific performance requirements:

 

Knurled Fin This variation features an interference fit, utilizing mechanical knurling to secure the fin material to the tube wall surface, enhancing stability and heat exchange.

LL Fin The Double Overlap fin, or double LL, provides enhanced coverage with a double strip thickness, fully enveloping the base tube for superior thermal efficiency.

Perforated L Fin This fin type features 'tear drop' slits along the helix that disrupt air flow, optimizing the heat transfer process.

 

L-Foot Fin / Wrap-On Fin

L-Foot Tension Wound Finned Tubes Also known as Wrap-On Finned Tubes, these are ideal for applications with temperatures below 300 degrees Fahrenheit, offering essential tube wall protection for low-temperature scenarios. L-Foot tension wound finned tubes are constructed by helically wrapping a fine aluminium fin strip tightly around the tube circumference, ensuring a snug fit. A distinctive 'foot' is formed on one side of the fin strip, which gives rise to the term L-Foot. The strip is wound with precision, with the foot exerting pressure on the tube's outer surface to maintain a secure attachment. Each L's short horizontal limb contacts the base-tube surface, providing comprehensive coverage for enhanced protection and performance. The tension applied during wrapping ensures that the fin foot is seated firmly, securing the fin in place with unwavering tightness. Our L-footed finned tubing excels in delivering maximum heat transfer efficiency at reduced temperatures. Its unique L-shaped design provides firm resistance against heat cycling and high-velocity air vibrations, maintaining structural integrity. Additionally, this fin offers significant atmospheric protection against corrosion, safeguarding the tube wall effectively. The extensive contact area between the tube and finning amplifies heat transfer capabilities, ensuring superior thermal conduction. This fin design stands out for its remarkable efficiency paired with cost-effectiveness, making it a preferred choice in various applications.

 

To prevent unraveling and ensure consistent contact between the fin foot and tube, the fin ends are securely stapled, maintaining their optimal performance over time. The embedded finned tube plays a pivotal role in the air cooler's functionality, efficiently transferring heat from the tube wall to the surrounding ambient air via the fin.

 

Advantages:

Perfectly engineered for low-temperature applications, ensuring optimal performance.

This finning method stands out as the most cost-effective solution compared to other techniques.

Easily remove failed fins during production, allowing the bare tube to be reused for finning, maximizing efficiency.

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

Fins can be mounted on a thin-walled tube, particularly advantageous when using costly alloy core tubes.

Capable of withstanding temperatures up to 130°C, this tube resists atmospheric corrosion and thermal stress.

 

Application:

Oil and gas refineries

Petroleum, chemical, and petrochemical industries

Natural gas treatment facilities

Steel manufacturing industry

Power generation plants

Air conditioning systems

Compressor cooling applications

KL Footed Fin / Knurled L Footed Fin

The KL fin is commonly referred to as the knurled L fin. Similar to the Wrap-On fin, this finned tube is crafted using both Wrap-On and Embedded techniques. Crafted from strips shaped into an L, these fins are then rolled into a taper creating a curling effect. Fins are helically wound onto the tube in a seamless loop under tension. The fin tightly embraces the tube. A spinning tool knurls the base tube, integrating the fin's foot into the knurling, ensuring a snug fit and enhanced thermal efficiency.

 

The fin's foot aligns with the subsequent fin, eliminating gaps between fins. This configuration provides exceptional protection against corrosion for the tube. Similar to L fins, the fins are secured at each end to prevent unwinding. KL-Foot tension wound finned tubes are predominantly used in metal-related applications. Can endure temperatures up to 320°C (608°F) for optimal operation.

Advantages:

Built with corrosion-resistant technology for enhanced longevity.

Engineered for superior vibration resistance.

Capable of withstanding extreme temperatures up to 320°C (608°F).

Offers unparalleled thermal performance and stress resistance with comprehensive protection against air corrosion.

KL fins can seamlessly replace any existing finned tube type.
 

LL-Foot Fin / Overlapped L

 

Fins are meticulously crafted from strips, forming a double-stepped L shape that curls into a taper. The LL-Foot Fin - Overlapped L is helically coiled onto the tube under controlled tension. The fin envelops the tube, with each fin's foot overhanging the next, ensuring the base tube is fully covered. This design effectively shields the tube from corrosion. In corrosive environments, this tube design is often preferred over the pricier extruded type fin.

 

The fins are meticulously secured at each end, mirroring the reliable technique used in L-type fins, ensuring maximum stability and performance. The robust LL-type fin tube is engineered to withstand temperatures soaring up to an impressive 350 degrees Fahrenheit (177°C), catering to demanding thermal environments with ease.
