Product Description

Product Parameters

At Cangzhou Datang Steel Pipe Co., Ltd., we boast an impressive range of finned tubes, including tension wound finned tubes, embedded finned tubes, and extruded finned tubes, each catering to distinct heat transfer needs.

Our Tension Wound Finned Tubes are masterfully crafted by winding a strip of premium aluminium or copper around the tube under precise tension, ensuring exceptional performance. The advanced strip winding technology permits a variety of fin types such as L-Fin, LL-Fin, and KL-Fin, each designed for specific heat exchange applications.

Embedded fins, also known as G-Fins, are meticulously created by winding an aluminium or copper strip into a helical groove that is skillfully machined on the outer surface of the tube.

Tension wound, embedded, and extruded finned tubes are key components in air coolers, prominently used in these diverse application sectors:

Power Plant Heat Exchangers: Perfectly suited for electric, nuclear, thermal, and geothermal power plants.

Steam Condensate Systems: Optimized for efficient function.

Chemical and Petrochemical Industry: Tailored for robust performance in demanding environments.

Food Processing and Refrigeration: Ensures optimal operational efficiency.

Industrial Applications: Essential for steel mills, incinerators, and gas compression facilities.

L-Foot Finned Tube: A Highlight of Innovation

Our L-Footed Finned Tubing is both highly efficient and economically viable, maximizing heat transfer even at lower temperatures. The ingenious L-shaped design ensures robust fin attachment, adeptly handling heat cycling and high-velocity air vibrations.

We offer L-Foot Finned Tubes in several innovative variations for enhanced performance:

Knurled Fin - An innovative interference fit fin that features mechanical knurling to bond the fin material securely to the tube wall surface.

LL Fin - Double Overlap Fin: This unique design covers the entire base tube with a double strip thickness, ensuring superior heat transfer.

Perforated L Fin - This enhancement introduces 'tear drop' slits along the fin's helix, effectively disrupting airflow to improve efficiency.

L-Foot Fin / Wrap-On Fin

L-Foot Tension Wound Finned Tubes commonly referred to as Wrap-On Finned Tubes, are ideal for applications with temperatures not exceeding 300°F, providing essential tube wall protection at lower temperatures. These tubes feature a finely wound thin aluminium fin strip that envelops the tube circumference with precision. A distinct 'foot' is crafted on one side of the fin strip, origin of the term L-Foot. The strip is wound meticulously, ensuring the foot remains in firm contact with the tube's outer surface. Each L's short horizontal limb maintains complete contact with the base-tube surface, enhancing heat transfer. The tension applied during the winding process ensures the fin foot is seated firmly on the tube, retaining its optimal position. L-footed finned tubing excels in maximizing heat transfer while maintaining low temperature efficiency. The proprietary L-shaped design ensures fins remain secure against heat cycling and high-velocity air vibrations. This design offers substantial atmospheric protection against corrosion, prolonging the tube's lifespan. The extensive contact surface between the tube and finning significantly boosts heat transfer. Renowned for its high efficiency and cost-effectiveness, this fin design is an industry-leading choice.

The fin ends are securely stapled to prevent unraveling, maintaining critical contact between the fin foot and tube. This contact is vital for air cooler operation, facilitating efficient heat transfer from the tube wall to the surrounding air.

Advantages:

Perfectly tailored for low-temperature applications, ensuring unmatched efficiency.

Our finning type stands out as the most cost-effective solution when compared to other methods.

Easily remove failed fins during production and seamlessly reuse the bare tube for finning anew.

Say goodbye to the need for helical grooves over the core tube, enhancing simplicity and ease.

Easily place fins on ultra-thin-walled tubes, especially beneficial when using costly alloy core tubes.

Withstand temperatures up to 130°C, confidently avoiding atmospheric corrosion and thermal stress.

Application:

The heart of oil and gas refineries, optimizing performance and efficiency.

A pivotal component in petroleum, chemical, and petrochemical industries.

Crucial in natural gas treatment processes, enhancing productivity.

Indispensable to the steel-making industry, ensuring superior results.

An essential part of power plants, boosting operational excellence.

Enhances air conditioning systems, ensuring optimal cooling efficiency.

Elevate compressor cooler performance with our advanced technology.

KL Footed Fin / Knurled L Footed Fin

The KL fin is renowned as the knurled L fin. This pioneering finned tube is nearly identical to the Wrap-On fin, crafted using both Wrap-On and Embedded techniques. Crafted from L-shaped strips, rolled into a taper for a distinctive curl, mirroring the L type. Helically wound onto the tube, maintaining a continuous loop under tension for enhanced stability. The fin closely embraces the tube with precision. A spinning tool knurls the base tube, allowing the foot of the fin to integrate tightly into the tube's knurling, enhancing the thermal bond.

The meticulously crafted fins align without gaps, thanks to the precision of the fin strip utilized. This innovation significantly shields the tube from corrosive damage. Mirroring L fins, these fins are securely fastened at both ends to prevent unwinding. KL-Foot tension wound finned tubes are the go-to choice in metal applications. Capable of operating at temperatures up to 320°C (608°F) without compromise.

Advantages:

Tubes with superior corrosion resistance, standing the test of time.

Built to withstand vibrations, ensuring longevity and reliability.

Survives extreme temperatures reaching 320°C (608°F), maintaining performance.

A perfect fusion of high thermal performance, stress resistance, and air corrosion protection.

KL effortlessly replaces any finned tube type, offering unmatched versatility.

LL-Foot Fin / Overlapped L

Crafted from strips akin to the L type, but with a meticulously controlled stepped double L foot shape. The LL-Foot Fin - Overlapped L is expertly helically coiled onto the tube under tension for superior results. The fin tightly grips the tube, with each fin elegantly overlapping the next, ensuring full coverage. The tube is impeccably shielded from corrosion, thanks to this innovative design. A preferred alternative to the costly extruded type fin in corrosive environments.

Fins are securely fastened at each end, just as with L fins, ensuring stability. The LL-type fin tube is meticulously engineered to endure and perform at temperatures soaring up to 350 degrees Fahrenheit (177°C), ensuring reliability and high efficiency in demanding thermal environments.
