At Cangzhou Datang Steel Pipe Co., Ltd., we proudly offer a diverse array of finned tubes tailored to meet your industrial cooling needs. Our selection includes the highly efficient tension wound finned tubes, the precision-crafted embedded finned tubes, and the robust extruded finned tubes.
Our tension wound finned tubes are expertly crafted by winding a durable strip of either aluminium or copper around the tube, strategically creating tension for optimal performance. Utilizing advanced strip winding technology, we offer an assortment of fin types to suit your specific requirements: L-Fin, LL-Fin, and KL-Fin.
Embedded fins (G-Fins) are meticulously manufactured by winding an aluminium or copper strip into a precisely machined helical groove on the tube's exterior surface.
Our tension wound, embedded, and extruded finned tubes are integral components for air coolers, widely applied across various fields, including:
Heat exchangers in power plants, encompassing electric, nuclear, thermal, and geothermal power facilities.
Steam condensate systems, ensuring efficient heat transfer and energy conservation.
Chemical and petrochemical industry, where reliability and durability are paramount.
Food processing plants and state-of-the-art refrigeration technology, maintaining optimal conditions.
Industrial sectors such as steel mills, incinerators, and gas compression facilities.
L-Foot Finned Tube
The L-Foot Finned Tube is designed for maximum heat transfer efficiency, offering a cost-effective solution for lower temperature applications. Featuring a distinctive L-shaped architecture, it ensures fins remain securely in place, even under intense heat cycling and high-velocity air conditions.
Our L-Foot Finned Tube is available in various fin configurations, including:
Knurled Fin - A specialized interference fit fin, with mechanical knurling enhancing the connection between the fin material and the tube wall surface.
LL Fin - With double overlap coverage, the LL Fin provides a robust, double thickness layer over the entire base tube for enhanced durability.
Perforated L Fin - This innovative design features 'tear drop' slits along the helix, effectively disrupting air flow for superior performance.
L-Foot Fin / Wrap-On Fin
L-Foot Tension Wound Finned Tubes also recognized as Wrap-On Finned Tubes, are ideal for applications with temperatures not exceeding 300 degrees Fahrenheit, offering protective coverage for the tube wall in low-temperature scenarios. L-Foot tension wound finned tubes are composed of a thin aluminium fin strip, expertly wrapped helically around the tube's circumference for secure placement. A 'foot' is ingeniously formed on one side of the fin strip, aptly named the L-Foot. The strip is meticulously wound around the tube, with the foot snugly resting on the tube's outer surface for maximum coverage. The short horizontal limb of each L maintains full contact with the base-tube surface, ensuring comprehensive coverage. Tension applied to the fin strip during wrapping ensures the fin foot is firmly seated on the tube, securing the fin in place. Our L-footed finned tubing is engineered for superior heat transfer at lower temperatures, providing an economical and efficient solution. The unique L-shape design ensures fins remain rigidly secured, even amidst heat cycling and high-velocity air vibrations. This design also offers a level of atmospheric protection for the tube wall, safeguarding against potential corrosion. The extensive contact surface between the tube and the fin enhances heat transfer significantly. This fin design is crafted to be highly efficient while remaining cost-effective, offering unparalleled value.
To prevent any unravelling and ensure the enduring connection between the fin foot and the tube, the ends of the fins are carefully stapled. This contact is of paramount importance to the efficient function of the air cooler. It ensures the seamless transfer of heat from the tube wall, through the fin, and finally to the ambient air surrounding it. This critical process is key to optimal air cooling performance.
Advantages:
Perfectly tailored for low-temperature applications, providing reliable performance even in chilly environments.
The finning method employed here is the most cost-efficient approach compared to other methods, ensuring maximum value without compromising on quality.
In the event of failure, the fins can be effortlessly removed during production, allowing the bare tube to be reused for finning, thus promoting sustainability.
Eliminates the need to carve a helical groove over the core tube, simplifying the production process.
Fins can be affixed to very thin-walled tubes, especially beneficial when using costly alloys as the core tube, maximizing material efficiency.
Capable of withstanding temperatures up to 130°C, ensuring no risk of atmospheric corrosion or thermal stress, promising durability and long-term usage.
Application:
Crucial to operations in oil and gas refineries, enhancing the cooling efficiency significantly.
Widely applied across the petroleum, chemical, and petrochemical industries, offering robust cooling solutions.
Integral to the natural gas treatment sector, providing reliable thermal management.
Essential in the steel making industry, ensuring effective cooling processes.
Plays a vital role in power plants, ensuring efficient air cooling solutions that enhance performance.
Enhances air conditioning systems with superior cooling capabilities.
Ideal for compressor coolers, ensuring optimal operation and efficiency.
KL Footed Fin / Knurled L Footed Fin
The KL fin is also known as the knurled L fin, showcasing a unique design for enhanced performance. This finned tube shares similarities with the Wrap-On fin, crafted using both Wrap-On and Embedded techniques for superior bonding. The fins are meticulously crafted from strips, shaped into an L form comparable to the L type, and then rolled into a taper that elegantly curls. These are then helically wound onto the tube in a continuous loop under tension, ensuring a secure fit. The fin snugly embraces the tube, guaranteeing a secure attachment. A spinning tool knurls the base tube, and the fin's foot is knurled into the base tube's knurling, ensuring a tight bond and enhanced thermal performance.
Should the correct fin strip be utilized, each fin will seamlessly meet the next, leaving no gaps, ensuring a uniform surface. This design effectively shields the tube from corrosion, significantly increasing its lifespan. Much like L fins, these fins are secured at each end to prevent unwinding, ensuring long-term reliability. In metal-related applications, KL-Foot tension wound finned tubes are the go-to choice, offering exceptional performance. Can withstand a maximum operating temperature of up to 320°C (608°F), making it ideal for high-temperature applications.
Advantages:
Corrosion-resistant Tubes
Outstanding vibration resistance, promising stability and enduring performance.
Capable of withstanding temperatures up to 320°C (608°F), ensuring reliability in extreme conditions.
Combines high thermal performance and stress resistance with protection from air corrosion, creating an unmatched solution.
KL can replace any form of finned tube, offering versatility and adaptability.
LL-Foot Fin / Overlapped L
The fins originate from strips, akin to the L type, although the foot is crafted into a meticulously controlled double L shape. The LL-Foot Fin - Overlapped L is then helically coiled onto the tube under tension, ensuring a snug fit. The fin clings tightly to the tube, with each fin overhanging the foot of the next, completely covering the base tube. This comprehensive coverage effectively protects the tube from corrosion, extending its operational life. In corrosive environments, this tube type is often selected as a cost-effective alternative to more expensive extruded types.
Fins are meticulously secured at each end in the same reliable manner that L fins are, ensuring maximum durability and performance. Our LL-type fin tube is engineered to withstand temperatures soaring up to 350 degrees Fahrenheit (177°C), making it the ideal choice for high-heat applications.
