Cangzhou Datang Steel Pipe Co., Ltd. proudly offers a diverse array of finned tubes to meet your specific needs. Choose from tension wound finned tubes, precision-engineered embedded finned tubes, or robust extruded finned tubes.
Tension wound finned tubes are expertly crafted by wrapping a strip of high-quality aluminium or copper tightly around the tube, creating a durable and efficient heat transfer solution. Our advanced strip winding technology enables the production of various fin types, including L-Fin, LL-Fin, and KL-Fin, each designed for superior performance.
Embedded fins (G-Fins) are meticulously manufactured by spiraling aluminium or copper strips into helical grooves precision-cut into the tube's outer surface, ensuring optimal heat exchange efficiency.
Our tension wound, embedded, and extruded finned tubes are at the heart of air cooler systems. These versatile components are essential in several key industries:
Heat exchangers for power plants, including electric, nuclear, thermal, and geothermal facilities.
Efficient solutions for steam condensate systems.
Critical applications within the chemical and petrochemical industry.
Integral to food processing plants and cutting-edge refrigeration technology.
Vital for various industrial applications, including steel mills, incinerators, and gas compression facilities.
L-Foot Finned Tube
Engineered for efficiency, the L-footed finned tubing provides exceptional heat transfer capabilities at lower temperatures, making it a cost-effective solution. With a distinct L-shaped profile, the fins remain securely attached, resilient to heat cycling and high-velocity air vibrations.
Explore our L-Foot Finned Tube variations, each tailored to enhance your system's performance:
Knurled Fin - Features an interference fit with mechanical knurling to ensure a strong bond between the fin material and tube wall.
LL Fin - The double overlap fin design offers comprehensive double strip thickness coverage across the base tube.
Perforated L Fin - Innovatively designed to create "tear drop" slits along the helix, disrupting airflow for enhanced performance.
L-Foot Fin / Wrap-On Fin
L-Foot Tension Wound Finned Tubes also recognized as Wrap-On Finned Tubes, are ideal for low-temperature applications, effectively protecting against temperatures up to 300 degrees Fahrenheit. Crafted with precision, these tubes feature a thin aluminium fin strip meticulously wound in a helical pattern around the tube’s circumference. A distinctive "foot" is adeptly formed on one side of the fin strip, giving rise to the name L-Foot. The strip is wound with precision around the tube, ensuring the foot maintains firm contact with the tube’s outer surface. The cleverly designed short horizontal limb of each L offers complete base-tube surface coverage. The tension within the fin strip, as it is expertly wrapped, ensures the fin foot is securely seated on the tube, holding the fin steadfast in place. L-footed finned tubing is your go-to choice for maximizing heat transfer efficiency at lower temperatures. The unique L-shaped design ensures fins are held rigidly, resisting heat cycling and high-velocity air vibration with ease. This fin design provides a level of atmospheric protection, guarding the tube wall against potential corrosion. An extensive contact surface between the tube and the finning significantly boosts heat transfer efficiency. This innovative fin design is both highly efficient and economically viable, delivering outstanding results.
The ends of the fins are firmly stapled to prevent the aluminium fin from unraveling and to maintain consistent contact between the fin foot and the tube, ensuring long-lasting performance. This vital contact is fundamental to the efficient functioning of the air cooler, as it facilitates the essential transfer of heat from the tube wall, traverses through the fin, and disperses into the ambient surrounding air.
Advantages:
Ideal for low-temperature applications, ensuring optimal performance and efficiency.
The finning type stands out as the most economically advantageous method when compared to alternative options.
Any failed fins can be effortlessly removed during production, allowing the bare tube to be reused for finning, enhancing sustainability.
Eliminates the necessity of creating a helical groove over the core tube, simplifying the production process.
Fins can be placed on an exceptionally thin-walled tube, which is highly desirable when employing expensive alloys as the core tube.
The tube boasts resilience, enduring temperatures up to 130°C without succumbing to atmospheric corrosion or thermal stress.
Application:
Perfectly suited for oil and gas refineries, boosting efficiency and reliability.
Widely employed in petroleum, chemical, and petrochemical industries for superior performance.
Essential in natural gas treatment, enhancing operational effectiveness.
Invaluable to the steel making industry, ensuring robust and reliable processes.
A key component in power plants, elevating energy efficiency.
Highly effective in air conditioning, improving cooling capabilities.
An integral part of compressor coolers, ensuring optimum cooling.
KL Footed Fin / Knurled L Footed Fin
The KL Fin is also recognized as the Knurled L Fin, renowned for its top-tier performance. This finned tube closely mirrors the Wrap-On fin and is crafted utilizing both Wrap-On and Embedded techniques for unparalleled efficiency. Fins are formed from strips prepared into an L shape akin to the L type, which are then rolled into a taper that causes them to curl elegantly. They are then helically wound onto the tube in a seamless loop under tension, ensuring optimal performance. The tube is tightly embraced by the fin, maximizing thermal contact. A spinning tool intricately knurls the base tube, and the fin's foot is knurled into the base tube's knurling, creating a secure bond and enhanced thermal performance.
When the correct fin strip is used, the foot of one fin aligns perfectly with the next, leaving no space between them and ensuring superior protection. This meticulous design helps safeguard the tube against corrosion, extending its lifespan. Similar to L fins, these fins are affixed at each end to prevent unwinding, ensuring stability. KL-Foot tension wound finned tubes are typically employed in metal applications, delivering reliable performance. Handles temperatures up to 320°C (608°F), showcasing extraordinary versatility.
Advantages:
Tubes are corrosion-resistant, promising longevity and durability.
Built to resist vibration, maintaining stability and performance.
Guaranteed to withstand temperatures up to 320°C (608°F), ensuring high resilience.
Offers a unique blend of high thermal performance, stress resistance, and protection from air corrosion.
Any finned tube can be seamlessly replaced with KL, offering flexibility and efficiency.
LL-Foot Fin / Overlapped L
Fins are crafted from strips, similar to the L type, but with a carefully controlled stepped double L shape, rolled into a taper that curls gracefully. The LL-Foot Fin - Overlapped L is then helically wound onto a tube under tension, ensuring a precise fit. The fin clings to the tube, with one overhanging the foot of the next, completely covering the base tube. This design thoroughly protects the tube from corrosion, ensuring long-lasting durability. In environments where corrosion is a significant concern, our specially designed tube serves as a cost-effective and high-performance alternative to the pricier extruded fin type, offering enhanced durability and efficiency.
The fins are meticulously secured at both ends using the same reliable technique employed for securing L fins, ensuring stability and optimal heat transfer performance. The advanced LL-type fin tube is expertly engineered to withstand extreme conditions, functioning seamlessly at temperatures reaching up to 350 degrees Fahrenheit (177 degrees Celsius), making it ideal for demanding applications.
