Cangzhou Datang Steel Pipe Co., Ltd. proudly offers a comprehensive range of cutting-edge finned tubes: expertly crafted tension wound finned tubes, precision-engineered embedded finned tubes, and robust extruded finned tubes.
Our tension wound finned tubes are ingeniously created by precisely winding a strip made of superior aluminium or copper around the tube, all under calculated tension for premium performance. Our advanced strip winding technology facilitates the creation of diverse fin types: L-Fin, LL-Fin, and KL-Fin, ensuring a tailored solution for every cooling need.
Embedded fins, also known as G-Fins, are our specialty, engineered by intricately winding aluminium or copper strips into expertly machined helical grooves on the tube's outer surface, offering unparalleled efficiency.
These innovative tension wound, embedded, and extruded finned tubes are pivotal in the realm of air coolers, serving multiple high-demand applications:
Sophisticated heat exchangers for power plants, including electric, nuclear, thermal, and geothermal facilities.
Efficient steam condensate systems for optimal performance.
Versatile solutions for the chemical and petrochemical industries.
Essential components in food processing plants and cutting-edge refrigeration technology.
Vital systems for various industrial applications such as steel mills, incinerators, and gas compression facilities.
L-Foot Finned Tube
Our highly efficient and cost-effective L-Footed finned tubing delivers exceptional heat transfer capabilities at lower temperatures, ideal for a range of applications. The unique L-shaped design ensures the fins hold rigidly, enduring both heat cycling and high-velocity air vibrations effortlessly.
The versatile L-Foot Finned Tube is available in these innovative Fin variations:
Knurled Fin Featuring an interference fit type fin, this variant incorporates mechanical knurling of the fin material onto the tube wall surface for enhanced durability.
LL Fin This Double Overlap fin, known as Double LL, offers a double strip thickness for comprehensive coverage of the base tube, maximizing protection and efficiency.
Perforated L Fin This unique enhancement introduces 'tear drop' slits along the helix, effectively breaking up air flow for superior performance.
L-Foot Fin / Wrap-On Fin
Our L-Foot Tension Wound Finned Tubes also called Wrap-On Finned Tubes, are expertly crafted for applications where temperatures remain below approximately 300 degrees Fahrenheit, perfect for low-temperature environments requiring a degree of tube wall protection. These tubes are constructed with a thin aluminium fin strip meticulously wound helically around the tube circumference for optimal performance. A 'foot' is skillfully formed on one side of the fin strip, giving it the distinctive L-Foot name. The strip is then expertly wound around the tube, ensuring the foot bears firmly on the tube's outer surface. The short horizontal limb of each L is designed to be in complete contact with the base-tube surface, providing full coverage. The tension applied to the fin strip during wrapping ensures the fin foot is securely seated and firmly held in place, enhancing durability. Our L-footed finned tubing achieves maximum heat transfer even at lower temperatures, making it highly efficient. The unique L-shaped design holds the fins firmly, making them resilient against heat cycling and high-velocity air vibrations. In addition, this fin design offers a certain level of atmospheric protection for the tube wall, safeguarding against corrosion. The extensive contact surface between the tube and fin significantly enhances heat transfer efficiency. This innovative fin design is not only highly efficient but also exceptionally cost-effective.
To maintain integrity, the ends of the fins are stapled, preventing the aluminium fin from unravelling and ensuring continuous contact between the fin foot and the tube. This component is absolutely vital for the seamless operation of air coolers, as it facilitates the efficient transfer of heat from the tube wall, through the intricately designed fin, to the ambient air surrounding it.
Advantages:
Exceptionally suitable for applications involving low temperatures
This type of finning is recognized as the most cost-effective method when compared to alternative options.
The innovative design allows for failed fins to be effortlessly removed during production, enabling the bare tube to be reused for finning anew.
There is no necessity to create a helical groove over the core tube, enhancing simplicity and reducing production time.
This design permits the installation of fins on an ultra-thin-walled tube, a feature highly prized when utilizing costly alloys as the core tube material.
The robust tube is engineered to endure temperatures up to 130°C without succumbing to atmospheric corrosion or thermal stress, ensuring durability and longevity.
Applications:
Strategically utilized in oil and gas refineries
Essential for petroleum, chemical, and petrochemical industries
Integral to natural gas treatment processes
Indispensable in the steel-making industry
Vital for efficient operations in power plants
A key component in air conditioning systems
Crucial for optimizing compressor coolers
KL Footed Fin / Knurled L Footed Fin
The KL fin is famously known as the knurled L fin, a name that reflects its unique design characteristics. This finned tube, bearing a close resemblance to the Wrap-On fin, is crafted using a combination of both Wrap-On and Embedded techniques. The fins are meticulously prepared from strips shaped into an L form, akin to the L type, and then rolled into a taper, prompting them to curl elegantly. Subsequently, these fins are helically wound onto the tube in a relentless loop under precision tension. The fin embraces the tube with a snug fit, ensuring optimal performance. A sophisticated spinning tool knurls the base tube while the foot of the fin is expertly knurled into the tube's knurling, securing a robust bond and elevating thermal efficiency.
When the appropriate fin strip is applied, each fin seamlessly aligns with the next, leaving no gap between them. This meticulous design acts as a safeguard, protecting the tube from potential corrosion. Similar to L fins, these fins are securely fastened at each end to prevent any unwinding, ensuring stability. KL-Foot tension wound finned tubes are predominantly utilized in applications that involve metal, known for their resilience. Capable of withstanding a remarkable maximum operating temperature of 320°C (608°F)
Advantages:
Tubes crafted to be corrosion-resistant, offering enduring protection
Engineered for superior vibration resistance, ensuring longevity
Designed to endure temperatures reaching up to 320°C (608°F), providing exceptional durability.
Combines high thermal performance and stress resistance with unparalleled protection from air corrosion, creating a truly unique offering.
KL fins are versatile and can replace any form of finned tube, offering flexible solutions.
LL-Foot Fin / Overlapped L
Fins are crafted from strips in a manner similar to the L type, but with a foot meticulously shaped into a precise stepped double L form, then rolled into a taper for curling. The LL-Foot Fin - Overlapped L is then helically coiled onto a tube under controlled tension. Each fin elegantly clings to the tube, with one fin gracefully overhanging the foot of the next, ensuring complete coverage and protection of the base tube. This configuration offers exceptional protection to the tube against corrosion. In environments prone to corrosion, this tube form is frequently preferred over the more costly extruded type fin as an efficient alternative.
Our G Type Embedded Finned Tube is ingeniously designed with fins securely fastened at each end, mirroring the reliable attachment method found in traditional L fins, ensuring unparalleled durability and performance. Engineered with precision, the LL-type fin tube effortlessly withstands temperatures soaring up to an impressive 350 degrees Fahrenheit (177 degrees Celsius), making it a robust choice for high-temperature applications.
