Our esteemed company, Cangzhou Datang Steel Pipe Co., Ltd., proudly presents a versatile range of finned tubes, including tension wound finned tubes, embedded finned tubes, and extruded finned tubes, crafted with precision and excellence.
Tension wound finned tubes are ingeniously crafted by meticulously winding a strip made from premium aluminium or copper around the tube under a controlled tension, ensuring optimal performance. Our strip winding technology is at the forefront, offering a variety of fin types designed to suit diverse needs: L-Fin, LL-Fin, KL-Fin, each tailored to enhance your system's efficiency.
Embedded fins (G-Fins) are expertly manufactured by winding a strip of aluminium or copper into a helical groove, which is intricately machined on the tube's outer surface, ensuring maximum reliability.
These sophisticated tension wound finned tubes, embedded finned tubes, and extruded finned tubes form the backbone of air coolers, widely applied across industries such as:
Heat exchangers in power plants, whether electric, nuclear, thermal, or geothermal, ensuring seamless energy transfer.
Steam condensate systems, designed for optimal efficiency and reliability.
The chemical and petrochemical industries, supporting critical processes with unwavering precision.
Food processing plants and advanced refrigeration technology, ensuring quality and freshness.
Diverse industrial applications, from steel mills to incinerators and gas compression facilities, require top-tier finned tubes.
L-Foot Finned Tube
This highly efficient, cost-effective L-footed finned tubing is engineered to offer unparalleled heat transfer capabilities, especially at lower temperatures. The innovative L-shaped design ensures that fins are held rigidly to withstand both heat cycling and high velocity air vibrations, providing durable performance.
The L-Foot Finned Tube is available in several sophisticated fin variations, each designed to meet specific operational requirements:
Knurled Fin - Features an interference fit with meticulous mechanical knurling of the fin material, ensuring a robust bond to the tube wall surface.
LL Fin - The double overlap (LL-Fin) provides a double strip thickness, ensuring comprehensive coverage of the entire base tube.
Perforated L Fin - This advanced fin design includes "tear drop" slits around the helix, effectively disrupting airflow for enhanced performance.
L-Foot Fin / Wrap-On Fin
L-Foot Tension Wound Finned Tubes also recognized as Wrap-On Finned Tubes, excel in applications where operating temperatures remain below 300 degrees Fahrenheit, providing essential tube wall protection for low-temperature applications. Comprising a thin aluminium fin strip wrapped helically and tightly around the tube circumference, these tubes are crafted for superior efficiency. An 'L' or 'foot' is initially formed on one side of the fin strip, giving the L-Foot its distinct name. Subsequently, the strip is meticulously wound around the tube, with the foot exerting a firm grip on the tube's outer surface. Each 'L' features a short horizontal limb that remains in direct contact with the base-tube surface, ensuring full coverage. The tension in the fin strip during wrapping intensifies the bond, securely seating the fin foot onto the tube and holding it steadfastly in place. L-footed finned tubing exemplifies maximum heat transfer efficiency at reduced temperatures, optimizing operational performance. The distinct L-shaped design fortifies fins against the challenges of heat cycling and high-velocity air vibrations, ensuring long-lasting stability. This fin design provides a certain level of atmospheric protection against corrosion, prolonging the life of the tube wall. The expansive contact surface between the tube and the finning amplifies heat transfer, delivering superior thermal performance. This fin configuration is not only highly efficient but also economically advantageous, providing an exceptional solution for heat transfer needs.
The fin ends are stapled securely to prevent unraveling, maintaining constant contact between the fin foot and the tube, thus ensuring durability and efficiency. Ensuring optimal performance of the air cooler, this indispensable contact transfers heat seamlessly from the tube wall, journeying through the fin, and finally dissipating into the ambient air.
Advantages:
Ingeniously crafted for low-temperature applications, this solution stands unparalleled.
Experience unparalleled cost-effectiveness with our finning type, the most economical option available.
Innovatively designed, failed fins are effortlessly detachable during production, allowing the bare tube to be efficiently reused for finning anew.
Ingenious engineering removes the need for a helical groove on the core tube.
Our cutting-edge design permits fin placement on ultra-thin-walled tubes, especially beneficial when utilizing costly alloy core tubes.
Our tubes confidently endure temperatures soaring up to 130°C, immune to atmospheric corrosion and thermal stress.
Application:
Oil and gas refineries benefit immensely.
Essential in petroleum, chemical, and petrochemical industries.
Vital for natural gas treatment processes.
Indispensable in the steel-making industry.
A critical component in power plants.
Optimizes air conditioning systems.
Enhances efficiency in compressor coolers.
KL Footed Fin / Knurled L Footed Fin
The KL fin is synonymous with the knurled L fin. Mirroring the Wrap-On fin, this variant melds the Wrap-On and Embedded techniques in its construction. Crafted from meticulously designed L-shaped strips, the fins are rolled into a taper and gracefully wound onto the tube. In a continuous motion, the fins are helically wound onto the tube with precision and tension. The fin embraces the tube snugly. Via a rotating tool, the base tube is knurled, allowing the fin's foot to interlock with the knurling, ensuring a secure bond and augmented thermal efficacy.
The fins are ingeniously aligned with no gap, each foot touching the next, providing enhanced protection against corrosion. This design crucially shields the tube from potential corrosion. Resembling L fins, these fins are firmly attached at both ends to prevent unwinding. KL-Foot tension wound finned tubes are the go-to choice for metal-related applications. Withstands extreme temperatures of up to 320°C (608°F), delivering unmatched reliability.
Advantages:
Corrosion-resistant Tubes offer enduring protection.
Engineered for exceptional vibration resistance.
Unfazed by temperatures up to 320°C (608°F), these tubes maintain peak performance.
Boasting high thermal performance and stress resistance, coupled with air corrosion protection, this solution is truly extraordinary.
KL fins offer versatile adaptability, capable of replacing any finned tube variant.
LL-Foot Fin / Overlapped L
Crafted with a meticulous approach, these fins are formed from strips similar to L type, with a distinctive stepped double L shape, rolled into an elegant taper. The LL-Foot Fin, with its overlapped L design, is helically coiled onto the tube under tension. The fin firmly clings to the tube, with one fin's foot gracefully overlapping the next, ensuring complete coverage of the base tube. This innovative structure affords the tube superb corrosion protection. In harsh, corrosive environments, these tubes serve as a cost-effective alternative to the pricier extruded type fins.
The fins are meticulously secured at each end, utilizing a technique akin to the reliable L fins, ensuring steadfast attachment and optimal performance. Our LL-type fin tube boasts remarkable resilience, engineered to withstand temperatures soaring up to an impressive 350 degrees Fahrenheit (177 degrees Celsius), making it ideal for high-temperature applications.
