At Cangzhou Datang Steel Pipe Co., Ltd., we present a diverse range of finned tubes to cater to your varied needs: tension wound finned tubes, embedded finned tubes, and extruded finned tubes. Each type is meticulously designed to enhance the efficiency of air cooler systems.
Tension wound finned tubes are expertly crafted by winding a strip, composed of either aluminium or copper, tightly around the tube under tension. This method ensures a robust and reliable construction. Our advanced strip winding technology enables the creation of different fin types, including L-Fin, LL-Fin, and KL-Fin, each offering unique benefits to optimize your heat exchange processes.
Embedded fins (G-Fins) are intricately manufactured by winding an aluminium or copper strip into a precisely machined helical groove on the tube's outer surface. This design maximizes the fin's durability and performance.
Tension wound finned tubes, embedded finned tubes, and extruded finned tubes serve as the cornerstone of air cooler devices, finding applications in a multitude of fields, such as:
Heat exchangers utilized in power plants, spanning across electric, nuclear, thermal, and geothermal sectors.
Efficient steam condensate systems that demand high performance and reliability.
The dynamic and ever-evolving chemical and petrochemical industry, where precision and durability are paramount.
Food processing plants and cutting-edge refrigeration technology, ensuring quality and efficiency.
Industrial sectors, including steel mills, incinerators, and gas compression facilities, emphasizing robust and reliable solutions.
L-Foot Finned Tube
Our L-footed finned tubing is engineered to be both highly efficient and cost-effective, providing superior heat transfer at lower temperatures. The innovative L-shaped design ensures that fins remain securely in place, even under rigorous heat cycling and high velocity air vibration.
The L-Foot Finned Tube can also be customized with the following fin variations:
Knurled Fin - Featuring an interference fit type fin with mechanical knurling, this design firmly attaches the fin material to the tube wall surface for enhanced stability.
LL Fin - The Double Overlap fin (Double LL) provides comprehensive double strip thickness coverage, completely enveloping the base tube.
Perforated L Fin - This innovative design introduces 'tear drop' slits along the helix, effectively breaking up air flow for improved performance.
L-Foot Fin / Wrap-On Fin
L-Foot Tension Wound Finned Tubes known as Wrap-On Finned Tubes, are ideal for applications with temperatures under 300 degrees Fahrenheit, providing essential tube wall protection for low-temperature applications. L-Foot tension wound finned tubes are composed of a thin aluminium fin strip meticulously wound helically around the tube's circumference. Initially, a 'foot' is formed on one side of the fin strip (thus earning the name L-Foot). Subsequently, the strip is tightly wound around the tube, with the foot bearing directly on the tube's outer surface for optimal contact. The short horizontal limb of each L makes complete contact with the base-tube surface, ensuring thorough coverage. Tension in the fin strip during wrapping secures the fin foot forcefully onto the tube, holding the fin securely in place. L-footed finned tubing provides exceptional heat transfer capabilities, particularly at lower temperatures, enhancing overall system efficiency. The special L-shaped design ensures that fins remain steadfast under intense heat cycling and high-speed air vibration. This fin construction also offers a modest degree of atmospheric protection for the tube wall, safeguarding against corrosion. The extensive contact area between the tube and finning significantly boosts heat transfer efficiency. This design is both highly efficient and cost-effective, making it an excellent choice for economical performance.
The fin ends are meticulously stapled to prevent the aluminium fin from unravelling, maintaining firm contact between the fin foot and the tube. This crucial component is the heart of the air cooler operation. It seamlessly facilitates the transfer of heat from the tube wall through the fin, emanating it into the surrounding ambient air, ensuring efficient cooling performance.
Advantages:
Perfectly engineered for low-temperature applications, this product stands out with its versatility and reliability.
Its finning type represents the pinnacle of cost-effectiveness compared to other methods, balancing performance and budget.
Ingeniously designed, the failed fins can be effortlessly removed during production, allowing the bare tube to be reused for finning, enhancing sustainability.
Ingenious engineering eliminates the need for a helical groove on the core tube, simplifying the process.
The design allows for the placement of fins on extremely thin-walled tubes, particularly advantageous when using costly alloys as core material, ensuring both efficiency and economy.
This robust tube can withstand temperatures up to 130°C, providing resilience against atmospheric corrosion and thermal stress, proving its durability in challenging conditions.
Application:
Oil and gas refineries
Petroleum, chemical, and petrochemical industries
Natural gas treatment
Steel making industry
Power plants
Air conditioning
Compressor coolers
KL Footed Fin / Knurled L Footed Fin
The KL fin is alternatively recognized as the knurled L fin, exemplifying flexibility in its application. This finned tube is remarkably akin to the Wrap-On fin, crafted utilizing both Wrap-On and Embedded techniques, highlighting its innovative design. Crafted from strips pre-prepared into an L shape akin to the L type, these fins are rolled into a taper, creating a curled contour. The fin is helically wound onto the tube in a continuous loop, with precision tension, ensuring a secure fit. Each fin tightly embraces the tube, ensuring optimal thermal conductivity and efficiency. A spinning tool expertly knurls the base tube, with the fin's foot knurled into the base tube, forming a steadfast bond and enhancing thermal performance.
When the correct fin strip is utilized, the foot of one fin seamlessly meets the next, leaving no gaps, maximizing protection and efficiency. This meticulous design helps safeguard the tube from corrosion, prolonging its lifespan and performance. Analogous to L fins, these fins are securely attached at each end to prevent unwinding, ensuring long-term reliability. In metal applications, KL -Foot tension wound finned tubes are typically preferred for their unparalleled performance. With a robust maximum operating temperature of up to 320°C (608°F), these tubes demonstrate exceptional endurance.
Advantages:
Corrosion-resistant Tubes
Crafted for extraordinary vibration resistance, these tubes promise stability and performance.
Withstanding temperatures up to 320°C (608°F), these tubes are engineered for high-temperature environments.
Delivering unmatched thermal performance and stress resistance, coupled with air corrosion protection, this combination is truly exceptional.
Easily replaceable, the KL fin can substitute any form of finned tube, offering versatility and convenience.
LL-Foot Fin / Overlapped L
Fashioned from strips like the L type, but with a foot crafted into a meticulously controlled stepped double L shape, rolled into a taper, creating a distinctive curl. The LL-Foot Fin - Overlapped L is skillfully helically coiled onto a tube under tension, ensuring a secure hold. The fin firmly clings to the tube, with each fin elegantly overhanging the foot of the next, offering complete coverage and protection. Designed to protect the tube from corrosion, this configuration ensures longevity and reliability. In corrosive environments, this tube offers a cost-effective alternative to expensive extruded type fins, without compromising on quality.
Our state-of-the-art Durable G Type Embedded Finned Tube ensures robust and secure fin attachment at each end, emulating the steadfast method of L fins, thus promising reliable performance and longevity. Designed to withstand challenging thermal conditions, the LL-type fin tube is expertly crafted for optimal efficiency at temperatures soaring up to 350 degrees Fahrenheit (177 degrees Celsius), ensuring superior performance in high-temperature environments.
