At Cangzhou Datang Steel Pipe Co., Ltd., we proudly present a diverse range of finned tubes crafted to perfection: tension wound finned tubes, embedded finned tubes, and extruded finned tubes, each designed for superior performance.
Tension wound finned tubes are ingeniously engineered by meticulously winding a strip of aluminium or copper around the tube under tension, ensuring robust and efficient heat transfer. Our state-of-the-art strip winding technology enables the creation of various fin types including L-Fin, LL-Fin, and KL-Fin, each offering unique benefits for your cooling solutions.
Embedded fins, also known as the G-Fins, are crafted by expertly winding an aluminium or copper strip into a helical groove machined on the tube's outer surface, providing a seamless and durable fin application.
These tension wound, embedded, and extruded finned tubes are integral components for air coolers, serving across multiple sectors such as:
Heat exchangers in power plants, whether electric, nuclear, thermal, or geothermal, rely on our advanced finned tube technology.
Steam condensate systems benefit from our precision-engineered finned tubes, enhancing performance and efficiency.
Chemical and petrochemical industries capitalize on our robust finned tubes for their demanding applications.
Food processing plants and refrigeration technology sectors utilize our finned tubes for optimal thermal management.
Industrial applications, including steel mills, incinerators, and gas compression facilities, harness the power of our finned tubes for unparalleled performance.
L-Foot Finned Tube
Our L-footed finned tubing stands out for its remarkable efficiency and affordability, offering maximum heat transfer even at lower temperatures. The distinctive L-shaped design ensures the fins remain firmly in place, enduring heat cycling and high velocity air vibrations effortlessly.
We also provide the L-Foot Finned Tube in these innovative variations:
Knurled Fin - Features an interference fit with mechanical knurling, enhancing the bond between the fin material and the tube wall.
LL Fin - Offers double overlap fin coverage, providing a robust double strip thickness coverage across the entire base tube.
Perforated L Fin - This design innovation introduces "tear drop" slits around the helix, effectively disrupting air flow for optimal thermal performance.
L-Foot Fin / Wrap-On Fin
L-Foot Tension Wound Finned Tubes also known as Wrap-On Finned Tubes, are ideal for applications involving temperatures under 300°F, offering necessary protection for the tube wall. These tubes feature a thin aluminium fin strip expertly wound helically around the tube, ensuring tight contact for maximum efficiency. A "foot" is meticulously formed on one side of the fin strip, giving rise to the iconic L-Foot designation. The strip is tightly coiled around the tube, with the foot maintaining secure contact with the outer surface, ensuring stability. The horizontal limb of each L shape remains in contact with the base tube surface, providing complete coverage. The tension in the fin strip ensures the fin foot is forcefully seated on the tube, maintaining a firm grip for optimal heat transfer. L-footed finned tubing excels in transferring heat efficiently at lower temperatures, representing a cost-effective solution. Its distinctive L-shaped design ensures the fins are steadfast, enduring both heat cycling and high-speed air vibrations. This fin configuration offers substantial atmospheric protection for the tube wall, guarding against corrosion. The expansive contact area between the tube and the fin enhances overall heat transfer capabilities. This design seamlessly combines efficiency with cost-effectiveness, making it a preferred choice.
To ensure longevity, the fin ends are meticulously stapled to prevent any unwinding, maintaining the crucial contact between fin foot and tube. Such contact is vital for the air cooler's functionality, as heat is transferred from the tube wall, through the fin, to the ambient air.
Advantages:
Specifically engineered for low-temperature applications, this product excels in efficiency and performance.
Utilizing the most cost-effective finning method available, it stands out against competitors.
If any fins fail during production, they can be swiftly removed without hassle, allowing the bare tube to be seamlessly reused for finning.
Ingeniously designed, there is no requirement for creating a helical groove over the core tube, simplifying production and reducing costs.
Fins can be placed on an exceptionally thin-walled tube, which is particularly advantageous when utilizing costly alloys as the core tube.
The tube exhibits remarkable durability, withstanding temperatures up to 130°C without succumbing to atmospheric corrosion or thermal stress.
Application:
An essential component in oil and gas refineries, ensuring optimal operational efficiency.
Perfectly suited for use in petroleum, chemical, and petrochemical industries.
Highly effective in natural gas treatment processes, enhancing productivity.
Vital to the steel-making industry, contributing to enhanced process efficiency.
A critical asset in power plants, supporting robust and reliable power generation.
Integral to air conditioning systems, providing superior cooling solutions.
Essential for compressor coolers, offering unmatched performance.
KL Footed Fin / Knurled L Footed Fin
The KL fin is also known as the knurled L fin, a testament to its unique design and functionality. This innovative finned tube mirrors the Wrap-On fin, crafted with both Wrap-On and Embedded techniques for superior performance. Crafted from strips pre-formed into an L shape similar to the L type, they are then rolled into a taper, causing them to curl with finesse. Meticulously helically wound onto the tube in a continuous loop, each fin is applied under tension to ensure precision. Each fin embraces the tube, creating a secure and efficient bond for consistent heat transfer. Through advanced technology, a spinning tool knurls the base tube, allowing the fin's foot to integrate seamlessly, enhancing thermal performance.
With a correctly utilized fin strip, fins lay flush against each other with no gaps, optimizing corrosion protection. This precise arrangement offers superior protection against corrosion, extending the lifespan of the tube. Similar to L fins, they are affixed at each end, preventing any unwinding and maintaining integrity. Ideal for metal-related applications, KL-Foot tension wound finned tubes are the choice for durability and efficiency. Capable of enduring up to 320°C (608°F), these tubes are designed for high-performance environments.
Advantages:
Built with corrosion-resistant materials, ensuring longevity and reliability.
Engineered for vibration resistance, it maintains stability under high-stress conditions.
Withstands high temperatures, up to 320°C (608°F), without compromising functionality.
Combines high thermal performance with robust stress resistance and air corrosion protection, offering a truly exceptional solution.
Compatible with any existing finned tube design, KL provides a versatile replacement option.
LL-Foot Fin / Overlapped L
Crafted from strips in a manner akin to L type, yet the foot forms a double L shape, rolled precisely for optimal performance. The LL-Foot Fin Overlapped L is meticulously coiled onto a tube under tension, ensuring a perfect fit. The fin clings to the tube, with a smart overhang, completely enveloping the base tube for maximum protection. This innovative design ensures robust corrosion protection, essential for longevity in harsh environments. Preferred in corrosive settings, this tube offers a cost-effective alternative to pricier extruded fin types.
Fins are meticulously secured at each end, akin to L fins, ensuring consistent performance and reliability. Experience the robust performance of our LL-type fin tube, engineered to withstand and operate efficiently at temperatures soaring up to 350 degrees Fahrenheit (177°C).
