Explore our diverse range of finned tubes expertly crafted for superior performance: tension wound finned tubes, embedded finned tubes, and extruded finned tubes.
Tension wound finned tubes are meticulously crafted by spirally winding a robust strip of aluminium or copper around the tube under precise tension. Our advanced strip winding technology innovatively offers a variety of fin types: L-Fin, LL-Fin, KL-Fin, each tailored to meet specific needs.
Embedded fins (G-Fins) are fabricated by skillfully winding aluminium or copper strips into a helical groove expertly machined on the tube's outer surface.
These finned tubes are indispensable in air coolers, prominently serving in industries, including:
Heat exchangers for power plants, encompassing electric, nuclear, thermal, and geothermal power facilities.
Sophisticated steam condensate systems for optimized performance.
Chemical and petrochemical sectors demanding precision and resilience.
Innovative solutions for food processing plants and the latest in refrigeration technology.
Robust applications in industrial settings such as steel mills, incinerators, and gas compression facilities.
L-Foot Finned Tube
Efficient and economical, L-footed finned tubing is engineered to maximize heat transfer while operating at lower temperatures. Its distinct L-shaped design ensures fins remain securely in place, enduring heat cycling and high-velocity air vibrations.
L-Foot Finned Tube can be customized with the following innovative Fin variations:
Knurled Fin - This fin features an interference fit with intricate mechanical knurling, enhancing the bond to the tube surface.
LL Fin - Double Overlap fin (Double LL) offers comprehensive dual strip thickness coverage.
Perforated L Fin - Ingenious fin face enhancements create 'tear drop' slits, effectively disrupting airflow for improved performance.
L-Foot Fin / Wrap-On Fin
L-Foot Tension Wound Finned Tubes Known as Wrap-On Finned Tubes, these are ideal for applications under 300°F, offering exceptional tube wall protection at low temperatures. L-Foot tension wound finned tubes are constructed from thin aluminium fin strips tightly wound helically around the tube. A distinctive 'foot' is crafted on one side of the fin strip, giving the L-Foot its name. The strip is meticulously wound around the tube, with the foot securely resting on the tube's exterior surface. The short horizontal limb of each L ensures comprehensive contact with the base-tube surface for optimal coverage. The tension in the fin strip during wrapping provides a firm seat for the fin foot, ensuring it remains steadfastly in place. L-footed finned tubing is designed for maximum heat transfer efficiency at lower temperatures. Its unique L-shaped configuration guarantees fins are securely held, resisting heat cycling and high-velocity air vibration. This fin design offers a degree of atmospheric protection, safeguarding the tube wall against corrosion. The extensive contact area between the tube and fin enhances the efficiency of heat transfer. This meticulously engineered fin design combines high efficiency with cost-effectiveness.
Fin ends are stapled to prevent the aluminium fin from unravelling, ensuring continuous contact between the fin foot and the tube. This pivotal contact point of the air cooler plays a crucial role in its operation, as it efficiently transfers heat from the tube wall, through the fin, to the surrounding ambient air, optimizing thermal performance.
Advantages:
Perfectly suited for applications requiring low temperatures, ensuring versatility and reliability.
This finning type represents the most economically advantageous method available, delivering exceptional value without compromising quality.
In the event of fin failure, the fins can be effortlessly removed during production, allowing the bare tube to be seamlessly reused for finning, enhancing resource efficiency.
No helical groove is necessary over the core tube, simplifying the production process and reducing costs.
Fins can be securely placed on ultra-thin-walled tubes, which is particularly beneficial when utilizing costly alloys as the core tube, maximizing material efficiency.
The tube can endure temperatures soaring up to 130°C, confidently resisting atmospheric corrosion and thermal stress, ensuring longevity and durability.
Application:
Oil and gas refineries
Petroleum, chemical, and petrochemical industries
Natural gas treatment
Steel making industry
Power plants
Air conditioning systems
Compressor coolers
KL Footed Fin / Knurled L Footed Fin
The KL fin is also known as the intricately designed knurled L fin. This finned tube is remarkably similar to the Wrap-On fin, crafted using both the Wrap-On and Embedded techniques to ensure superior performance. The fins are meticulously crafted from strips shaped into an L form akin to the L type, then skillfully rolled into a taper that induces a curl. Subsequently, it is helically wound onto the tube in a continuous loop under tension for optimal adhesion. The tube is snugly enveloped by the fin, ensuring a secure fit. A spinning tool elegantly knurls the base tube, allowing the fin's foot to be seamlessly knurled into the base tube, creating a robust bond that elevates thermal performance.
When the correct fin strip is utilized, the foot of one fin perfectly aligns with the next, leaving no space between fins, enhancing protection. This configuration provides exceptional protection for the tube against corrosion. Mirroring the attachment method of L fins, the fins are secured at each end to eliminate the risk of unwinding. In applications dealing with metal, KL-Foot tension-wound finned tubes are predominantly favored for their efficiency. Capable of withstanding a maximum operating temperature of 320°C (608°F), ensuring impressive resilience.
Advantages:
Corrosion-resistant Tubes
Exceptional vibration resistance
Engineered to endure temperatures soaring up to 320°C (608°F), delivering outstanding heat tolerance.
This unique combination of high thermal performance, stress resistance, and air corrosion protection is unparalleled.
KL fins can be seamlessly interchanged with any form of finned tube, offering versatility and adaptability.
LL-Foot Fin / Overlapped L
Crafted from strips similarly to the L type, the foot is meticulously prepared into a precise, stepped double L shape, rolled into a taper to enable curling. Subsequently, the LL-Foot Fin - Overlapped L is helically coiled onto a tube under tension for optimal adherence. The fin securely clings to the tube, with each fin overhanging the next, ensuring the base tube is completely shielded. This design provides exceptional protection for the tube against corrosion. In corrosive environments, this fin type is frequently chosen as a cost-effective alternative to the pricier extruded type fin, offering reliable performance.
At Cangzhou Datang Steel Pipe Co., Ltd., our Advanced G Type Embedded Finned Tube is ingeniously designed with fins securely attached at each end, mirroring the robust and reliable attachment method found in L fins. This ensures enhanced stability and longevity for superior thermal performance. Our LL-type fin tube is engineered to withstand extreme temperatures, comfortably operating at up to 350 degrees Fahrenheit (177°C). This makes it an ideal choice for a wide range of high-temperature applications, offering reliability and efficiency that meet the demands of challenging environments.
