Product Description
Cangzhou Datang Steel Pipe Co., Ltd. proudly offers a versatile selection of finned tubes, including tension wound finned tubes, embedded finned tubes, and extruded finned tubes.
Our tension wound finned tubes are expertly crafted by wrapping a strip of premium-grade aluminium or copper around the tube under precise tension for optimal performance. This advanced strip winding technology allows us to offer a variety of fin types: L-Fin, LL-Fin, KL-Fin, each designed for specific applications.
Embedded fins (G-Fins) are ingeniously created by inserting an aluminium or copper strip into a helical groove meticulously machined on the tube's outer surface.
These finned tubes, whether tension wound, embedded, or extruded, are integral components for air coolers, widely utilized in the following fields:
Heat exchangers in power plants across sectors including electric, nuclear, thermal, and geothermal energy industries.
Sophisticated steam condensate systems.
Chemical and petrochemical industries, demanding efficiency and reliability.
Innovative solutions for food processing plants and state-of-the-art refrigeration technology.
Industrial applications, encompassing steel mills, incinerators, and gas compression facilities.
L-Foot Finned Tube
Our highly efficient and budget-friendly L-footed finned tubing ensures maximum heat transfer even at lower temperatures, optimizing performance. The L-shaped design is engineered to hold fins securely, resisting heat cycling and high velocity air vibration effortlessly.
Our L-Foot Finned Tubes come in various innovative fin options, including:
Knurled Fin - Features an interference fit with mechanical knurling, enhancing the grip between the fin material and the tube wall.
LL Fin - With double overlap, this design provides robust double strip thickness coverage over the entire base tube, maximizing durability.
Perforated L Fin - Enhanced with "tear drop" slits around the helix, this design disrupts airflow for improved efficiency.
L-Foot Fin / Wrap-On Fin
Fin ends are securely stapled to prevent unraveling, maintaining the integrity of contact between the fin foot and tube. The seamless interaction between the tube wall and the fin is absolutely vital for the efficient operation of the air cooler. This sophisticated design ensures that heat is effectively transferred from the tube wall, through the fin, and into the ambient air, maximizing performance.
Advantages:
Perfectly engineered for low-temperature applications, offering a reliable solution for diverse conditions.
This finning type stands as the most economically viable option, delivering cost-effectiveness without compromising on quality, compared to other available methods.
A significant advantage is the ease with which failed fins can be removed during production, allowing the bare tube to be re-utilized for new finning, enhancing both efficiency and sustainability.
Eliminating the need for a helical groove on the core tube simplifies production, reducing complexity and costs.
Fins can be adeptly placed on very thin-walled tubes, which is especially advantageous when utilizing expensive alloys as the core tube, optimizing material use and cost.
These tubes boast remarkable resilience, withstanding temperatures up to 130°C without succumbing to atmospheric corrosion or thermal stress, ensuring longevity.
Application:
Oil and gas refineries: Optimized for high-efficiency thermal transfer in demanding conditions.
Petroleum, chemical, and petrochemical industries: Ideal for robust use in complex industrial processes.
Natural gas treatment: Ensures superior performance in natural gas processing applications.
Steel-making industry: A reliable choice for heat-intensive environments.
Power plants: Designed to meet the rigorous demands of power generation facilities.
Air conditioning: Enhances cooling efficiency while maintaining energy economy.
Compressor coolers: Ensures robust cooling performance in compression systems.
KL Footed Fin / Knurled L Footed Fin
The KL fin is also recognized as the knurled L fin, revered for its advanced thermal performance and durability. This finned tube, akin to the Wrap-On fin, is crafted using a sophisticated combination of Wrap-On and Embedded techniques to enhance efficiency. The fins are meticulously formed from strips into a distinctive L shape, then rolled into a taper to induce curling, optimizing the fin's structural integrity. With precision, it is helically wound onto the tube in a constant loop under tension, ensuring a snug fit. The design ensures that the tube is enveloped securely by the fin, promoting superior heat transfer. A spinning tool intricately knurls the base tube, allowing the foot of the fin to knurl into the tube's base, creating an exceptional bond and elevating thermal performance.
When the optimal fin strip is utilized, the foot of one fin meets the next without any gap, enhancing structural integrity and heat exchange. This design feature provides outstanding protection against corrosion, extending the tube's service life. Similar to L fins, these fins are firmly secured at each end to prevent unwinding, ensuring long-term stability. KL-Foot tension wound finned tubes are predominantly employed in metal-involving applications, known for their resilience. Capable of withstanding a maximum operating temperature of 320°C (608°F), making it suitable for high-temperature applications.
Advantages:
Corrosion-resistant Tubes: Engineered to resist corrosion, extending the life of the product in various environments.
Vibration resistance: Designed to withstand industrial vibrations, ensuring continuous and reliable performance.
These tubes are outstandingly equipped to endure temperatures up to 320°C (608°F), making them ideal for extreme conditions.
This unmatched combination of high thermal performance and stress resistance, coupled with protection from air corrosion, makes it a superior choice.
KL finned tubes are versatile and can be substituted for any form of finned tube, offering flexibility in application.
LL-Foot Fin / Overlapped L
Crafted in a similar fashion to the L type, these fins have a foot meticulously prepared into a double L shape, ensuring a precise and controlled fit. The LL-Foot Fin - Overlapped L is expertly coiled onto a tube under tension, guaranteeing a secure and efficient fit. The fin adheres tightly to the tube, with each fin overlapping the foot of the subsequent fin, fully covering the base tube for enhanced protection. This design ensures comprehensive protection against corrosion, contributing to the tube's durability and reliability. In environments where corrosion is a concern, this innovative form of tube serves as a cost-effective alternative to the more expensive extruded type fin. Its robust design ensures reliability and longevity, making it an invaluable asset in challenging settings.
Fins are meticulously secured at each end with the same reliable method used for L fins, ensuring steadfastness and durability throughout their lifecycle. The LL-type fin tube boasts impressive resilience, making it suitable for harsh conditions with temperatures soaring up to 350 degrees Fahrenheit (177 degrees Celsius). Its steadfast performance in high-temperature applications makes it a preferred choice in demanding industrial processes.
