Product Description

Product Parameters

Cangzhou Datang Steel Pipe Co., Ltd. proudly presents a versatile array of finned tubes for enhanced thermal performance, including tension wound finned tubes, embedded finned tubes, and the robust extruded finned tubes.

Tension wound finned tubes are artfully crafted by spiraling a strip composed of either aluminium or copper meticulously around the tube, ensuring optimal contact under tension. Our innovative strip winding technology generates a diverse assortment of fins, including L-Fin, LL-Fin, and KL-Fin, each designed to meet specific application needs.

Embedded fins (G-Fins) are ingeniously created by inserting aluminium or copper strips into a helical groove, precisely machined on the tube's exterior, ensuring a superior fit and performance.

These finned tubes, whether tension wound, embedded, or extruded, are integral components for air coolers, serving various demanding applications such as:

State-of-the-art heat exchangers designed for power plants, including electric, nuclear, thermal, and geothermal facilities, ensuring reliable operation and efficiency.

Cutting-edge steam condensate systems, maximizing energy recovery and efficiency.

Innovative solutions for the chemical and petrochemical industries, tailored to withstand harsh processing conditions.

Advanced applications in food processing plants and refrigeration technology, enhancing safety and efficiency.

Robust industrial applications, including steel mills, incinerators, and gas compression facilities, delivering reliable performance in demanding environments.

L-Foot Finned Tube

Our L-footed finned tubing is a marvel of efficiency and cost-effectiveness, delivering maximum heat transfer capabilities even at lower temperature ranges. The distinctive L-shaped architecture ensures the fins remain securely attached, expertly resisting heat cycling and high velocity air-induced vibrations.

We offer the L-Foot Finned Tube in several specialized variations to suit your specific requirements:

Knurled Fin - This innovative interference fit fin utilizes mechanical knurling to ensure a robust connection between the fin material and the tube surface.

LL Fin - Featuring Double Overlap fin coverage, this design provides double strip thickness over the entire base tube, enhancing durability and performance.

Perforated L Fin - Enhanced with unique "tear drop" slits around the helix, this design cleverly disrupts airflow, improving heat transfer efficiency.

L-Foot Fin / Wrap-On Fin

L-Foot Tension Wound Finned Tubes also known as Wrap-On Finned Tubes, these are ideal for applications where temperatures remain below 300 degrees Fahrenheit, providing tube wall protection for low-temperature requirements. Comprising a thin aluminium fin strip, these tubes are meticulously wound in a helical fashion around the tube circumference, ensuring perfect fit and performance. The process begins with forming a "foot" on one side of the fin strip, giving rise to the distinctive L-Foot name. This strip is then wound tightly, with the foot pressing firmly against the tube’s outer surface, ensuring uncompromised contact. Each short horizontal limb of the L configuration is in complete contact with the tube's base, optimizing coverage and efficiency. The tension applied during wrapping serves to seat the fin foot securely, holding each fin firmly and reliably in place. L-footed finned tubing is unparalleled in its ability to maximize heat transfer, even at lower temperatures. The L-shaped design ensures rigidity, expertly withstanding heat cycling and high velocity air vibrations for sustained performance. This fin design also offers a level of atmospheric protection for the tube wall, safeguarding against corrosion. With its broad contact surface, the connection between tube and finning is enhanced, optimizing heat transfer efficiency. Delivering high efficiency and cost-effectiveness, this fin design is second to none.

The fin ends are securely stapled to prevent unraveling, ensuring continuous contact between the fin foot and tube, maintaining reliability and performance. This contact serves as the linchpin for the air cooler's functionality, facilitating the seamless transfer of heat from the tube wall, through the fin, to the ambient air, ensuring optimal cooling performance.

Advantages:

Perfectly tailored for low-temperature applications, maximizing efficiency and durability.

The finning type emerges as the most cost-effective method, offering exceptional value without compromising quality.

Fins that fail can be effortlessly removed during production, allowing the bare tube to be reused for finning, fostering sustainability.

No requirement for helical grooving over the core tube, simplifying the process while ensuring robustness.

Fins can be positioned on a very thin-walled tube, an especially desirable trait when utilizing costly alloys as the core tube.

The tube withstands temperatures up to 130°C, free from risks of atmospheric corrosion or thermal stress, ensuring long-lasting reliability.

Application:

Oil and gas refineries, a crucial component in energy production.

Essential for the petroleum, chemical, and petrochemical industries, driving innovation and efficiency.

Vital in natural gas treatment, supporting cleaner energy solutions.

Integral to the steelmaking industry, enhancing production efficiency.

Key for power plants, improving energy output and reliability.

Indispensable for air conditioning systems, providing superior cooling solutions.

Critical for compressor coolers, maintaining optimal operating conditions.

KL Footed Fin / Knurled L Footed Fin

The KL fin is also recognized as the knurled L fin, known for its precision and efficiency. This finned tube closely resembles the Wrap-On fin, crafted using both Wrap-On and Embedded techniques for superior heat exchange. Fins are fashioned from strips prepared into an L shape, akin to the L type, and rolled into a taper that causes curling. Subsequently, it is helically wound onto the tube in a continuous loop under tension, ensuring a stable and effective heat transfer medium. The fin embraces the tube, maximizing surface contact and efficiency. A spinning tool intricately knurls the base tube, allowing the fin's foot to knurl into the base tube's knurling, creating a secure bond and enhanced thermal performance.

Proper fin strips ensure that one fin's foot bumps against the next, eliminating space between fins for optimized protection. This configuration provides excellent protection against tube corrosion, extending the product's lifespan. Similar to L fins, the fins are securely attached at both ends to prevent unwinding, ensuring reliability. KL-Foot tension wound finned tubes are typically deployed in metal applications, offering superior performance. Endures up to 320°C (608°F) maximum operating temperature, showcasing exceptional thermal resilience.

Advantages:

Corrosion-resistant Tubes, crafted to withstand the test of time and elements.

Engineered for vibration resistance, maintaining integrity under dynamic conditions.

Capable of withstanding temperatures up to 320°C (608°F), ensuring exceptional performance.

A unique combination of high thermal performance, stress resistance, and air corrosion protection.

KL finned tubes are versatile, easily replacing any form of finned tube, adapting to various needs.

LL-Foot Fin / Overlapped L

Fins are crafted from strips, akin to the L type, with the foot prepared into a stepped double L shape, allowing for controlled curling. The LL-Foot Fin - Overlapped L is meticulously helically coiled onto a tube under tension, ensuring security. The fin envelops the tube, with each fin's overhang securing the next, providing complete coverage and protection. This design offers superior corrosion protection for the tube, safeguarding its integrity over time. In environments where corrosion is a concern, the use of this innovative tube is often preferred as a cost-effective alternative to the pricier extruded-type fins. This choice ensures durability without compromising quality.

The fins are expertly secured at each end, mirroring the reliable method used for L fins, ensuring steadfast performance and structural integrity. The LL-type fin tube is engineered to withstand temperatures soaring up to 350 degrees Fahrenheit (177C), making it an ideal choice for high-temperature applications.
