At Cangzhou Datang Steel Pipe Co., Ltd., we proudly present a versatile array of finned tubes, expertly crafted to meet diverse industrial needs: tension wound finned tubes, embedded finned tubes, and extruded finned tubes.
Tension wound finned tubes are ingeniously fabricated by winding a robust strip of aluminium or copper around the tube with precision and tension, ensuring superior performance and durability. Our advanced strip winding technology provides an array of specialized fins to suit your exact requirements: L-Fin, LL-Fin, and the reliable KL-Fin.
Embedded fins (G-Fins) are meticulously crafted by skillfully winding an aluminium or copper strip into a helical groove, precisely machined on the tube's exterior surface, promising unparalleled efficiency.
The tension wound, embedded, and extruded finned tubes serve as pivotal components for air coolers, widely used in the following critical applications:
Enhance heat exchangers for power plants, including electric, nuclear, thermal, and geothermal facilities, with our cutting-edge finned tubes.
Optimize steam condensate systems for peak efficiency and reliability.
Transformative solutions for the chemical and petrochemical industry, streamlining processes and enhancing productivity.
Elevate food processing plants and refrigeration technology with our state-of-the-art finned tubes, ensuring top-tier performance.
Industrial applications such as steel mills, incinerators, and gas compression facilities greatly benefit from our durable and efficient solutions.
Specialized L-Foot Finned Tube
The L-footed finned tubing is a marvel of engineering, offering exceptional heat transfer capabilities at lower temperatures while maintaining cost-effectiveness. Its unique L-shaped design securely holds fins in place, capable of withstanding heat cycling and high-velocity air vibrations, ensuring long-lasting stability.
Our L-Foot Finned Tubes are available in various fin options to suit different needs:
Knurled Fin - Features an interference fit with mechanical knurling, ensuring a strong bond between the fin material and the tube wall surface for optimal performance.
LL Fin - Boasting a double overlap design (double LL), it provides robust double strip thickness coverage, ensuring comprehensive protection for the entire base tube.
Perforated L Fin - Enhanced with 'tear drop' slits around the helix to disrupt airflow, further augmenting efficiency and effectiveness.
L-Foot Fin / Wrap-On Fin
L-Foot Tension Wound Finned Tubes are also referred to as Wrap-On Finned Tubes, ideal for low-temperature applications not exceeding 300 degrees Fahrenheit where tube wall protection is essential. These tubes comprise a thin aluminium fin strip, expertly wound helically around the tube circumference for a snug fit. A "foot" is meticulously formed on one side of the fin strip, giving it the distinctive name, L-Foot. This strip is then expertly wound around the tube, ensuring the foot securely bears against the tube's outer surface. The short horizontal limb of each L fin precisely contacts the base-tube surface, offering complete coverage and protection. The tension applied as the fin is wrapped secures the fin foot firmly on the tube, maintaining consistent contact and effectiveness. The L-footed finned tubing excels in providing maximum heat transfer at reduced temperatures. Its distinctive L-shaped design ensures rigid fin attachment, capable of withstanding rigorous heat cycling and air vibrations. These fins offer substantial atmospheric protection against corrosion, safeguarding the tube walls over time. The extensive contact surface between the tube and finning significantly enhances heat transfer efficacy. This fin design not only maximizes efficiency but also remains a cost-effective choice for your operations.
The fin ends are securely stapled to prevent unraveling and maintain the critical contact between the fin foot and tube, ensuring ongoing reliability. This contact is absolutely crucial to the seamless operation of the air cooler, as it facilitates the essential transfer of heat from the tube wall, through the fin, to the encompassing ambient air.
Advantages:
Perfectly crafted for low-temperature applications, ensuring optimal performance in every scenario.
This finning type stands as the most cost-effective method available, offering unparalleled economic efficiency compared to alternative options.
The innovative design allows for seamless removal of failed fins during production, enabling the bare tube to be effortlessly reused for finning once more.
Ingeniously, there is no requirement to create a helical groove over the core tube, simplifying the production process.
Exquisitely engineered, it permits the placement of fins on a remarkably thin-walled tube, a highly desirable feature when utilizing costly alloys as the core tube.
The tube is robustly constructed to endure temperatures soaring up to 130°C, without the peril of atmospheric corrosion or thermal stress.
Application:
A quintessential choice for oil and gas refineries.
Widely applicable in petroleum, chemical, and petrochemical industries, enhancing industrial efficiency.
Ideal for natural gas treatment processes, offering unmatched reliability.
An invaluable asset in the steel-making industry, optimizing thermal management.
A pivotal component for power plants, ensuring consistent performance.
Perfectly suited for air conditioning systems, providing superior thermal exchange.
An excellent solution for compressor coolers, enhancing cooling efficiency.
KL Footed Fin / Knurled L Footed Fin
The KL fin is also recognized as the knurled L fin, celebrated for its robust and adaptable design. This remarkable finned tube closely resembles the Wrap-On fin, crafted using both Wrap-On and Embedded techniques for unparalleled versatility. The fins are meticulously crafted from strips prepared into an L shape, akin to the L type, then artistically rolled into a taper that induces curling. Subsequently, it is helically wound onto the tube in a seamless, continuous loop under tension. The fin embraces the tube, ensuring a snug fit and optimal thermal transfer. A specialized spinning tool expertly knurls the base tube, securing the foot of the fin into the knurling of the base tube, achieving a tight bond and enhanced thermal efficiency.
When the correct fin strip is utilized, the foot of one fin seamlessly aligns with the next, leaving no gaps between the fins. This meticulous design provides exceptional protection for the tube against corrosion. Analogous to L fins, the fins are securely attached at each end to prevent unwinding, ensuring durability. In metal-related applications, KL Foot tension wound finned tubes are typically the solution of choice. Designed to withstand maximum operating temperatures of up to an impressive 320°C (608°F).
Advantages:
Expertly crafted corrosion-resistant tubes, ensuring longevity and reliability.
Engineered for supreme vibration resistance, ensuring stability under dynamic conditions.
With the capacity to endure temperatures as high as 320°C (608°F), these tubes set a new standard in thermal resilience.
Combining high thermal performance and stress resistance with air corrosion protection, this offers an unrivaled, one-of-a-kind combination.
KL finned tubes are versatile and can replace any form of finned tube, adapting seamlessly to diverse requirements.
LL-Foot Fin / Overlapped L
Crafted from strips in a similar manner to the L type, the foot is expertly shaped into a meticulously controlled stepped double L, rolled into a taper for curling. The LL-Foot Fin - Overlapped L is then helically coiled onto a tube under tension, ensuring a perfect fit. The fin clings to the tube, with each fin elegantly overhanging the foot of the next, providing complete coverage of the base tube. This configuration affords the tube superior protection from corrosion, significantly extending its lifespan. In corrosive environments where durability and cost-effectiveness are paramount, this innovative G Type Embedded Finned Tube is frequently chosen as a superior alternative to the more costly extruded fin type.
Ingeniously designed, the fins are firmly secured at each end, mirroring the stability and reliability of the traditional L fins. The robust LL-type fin tube is expertly engineered to withstand temperatures soaring up to 350 degrees Fahrenheit (177°C), ensuring exceptional performance in demanding thermal conditions.
