Product Description

Product Parameters

Discover our diverse and versatile range of finned tubes, including tension wound finned tubes, embedded finned tubes, and extruded finned tubes, designed to meet your cooling needs.

 

Tension wound finned tubes are expertly crafted by tightly winding a high-quality strip of aluminium or copper around the tube under precise tension, ensuring superior performance. Our innovative strip winding technology offers a variety of fin types to suit your requirements: L-Fin, LL-Fin, and KL-Fin, each with unique benefits.

 

Embedded fins (G-Fins) are meticulously engineered by winding a strip of aluminium or copper into a precision-machined helical groove on the tube's outer surface.
 

Tension wound finned tubes, embedded finned tubes, and extruded finned tubes are essential components for air coolers, finding applications across various sectors:

 

Heat exchangers for power plants (electric, nuclear, thermal, and geothermal power plants), providing efficient thermal solutions.

Steam condensate systems, optimized for reliable and effective heat exchange.

Chemical and petrochemical industry, enhancing process efficiency and safety.

Food processing plants and refrigeration technology, ensuring optimal temperature control and energy savings.

Industrial applications (steel mills, incinerators, gas compression facilities), delivering robust performance in demanding environments.

 

L-Foot Finned Tube

 

Experience the power of L-footed finned tubing, offering unparalleled heat transfer at lower temperatures with cost-effective solutions. The distinctive L-shaped design ensures rigid fin attachment, standing up to heat cycling and high velocity air vibration.

The L-Foot Finned Tube is available in the following innovative fin variations:

 

Knurled Fin - Features an interference fit type with mechanical knurling, securing the fin material to the tube wall surface.

LL Fin - Offers double overlap fin coverage with double strip thickness, fully protecting the base tube.

Perforated L Fin - This enhancement introduces 'tear drop' slits around the helix, effectively breaking up air flow.

 

L-Foot Fin / Wrap-On Fin

L-Foot Tension Wound Finned Tubes also known as Wrap-On Finned Tubes, are the go-to choice for applications below 300 degrees Fahrenheit, offering essential low-temperature performance and tube wall protection. These tubes are constructed with a thin aluminium fin strip helically wound tightly around the tube circumference for maximum efficiency. An 'L-foot' is initially formed on one side of the fin strip, giving it the signature name. The strip is then wound securely around the tube, with the foot pressing firmly on the tube's outer surface. The short horizontal limb of each L ensures 360-degree contact with the base-tube surface, maximizing coverage. Tension in the fin strip during winding seats the fin foot with forceful precision, maintaining a secure hold. L-footed finned tubing delivers exceptional heat transfer at lower temperatures, combining efficiency with cost-effectiveness. The remarkable L-shaped design stabilizes fins to endure heat cycling and rapid air movement. This fin design provides a protective barrier against atmospheric corrosion for the tube wall. The extensive contact surface between the tube and finning optimizes heat transfer capabilities. This design is acclaimed for its high efficiency and unbeatable cost-effectiveness.

 

Fin ends are securely stapled, preventing aluminium fin unraveling and ensuring consistent contact between the fin foot and tube. This integral component is essential to the seamless operation of air coolers. It facilitates the critical transfer of heat from the tube wall, passing through the fin, and dispersing into the surrounding ambient air efficiently.

 

Advantages:

Perfectly crafted for low-temperature applications, ensuring adaptability and efficiency.

This finning type presents an exceptionally cost-effective solution, standing out among alternatives in economic value.

The design allows for effortless removal of failed fins during production, enabling the bare tube to be reused for finning without hassle.

Eliminates the need for carving a helical groove on the core tube, simplifying the process.

Fins can be seamlessly placed on a very thin-walled tube, especially beneficial when employing costly alloys as the core tube, maximizing resource efficiency.

The tube is engineered to endure temperatures up to 130°C, safeguarded against atmospheric corrosion and thermal stress.

 

Application:

Oil and gas refineries benefit greatly from its robust functionalities.

Indispensable in petroleum, chemical, and petrochemical industries, enhancing operational efficiency.

Vital in natural gas treatment, ensuring seamless processing and reliability.

Integral to the steel making industry, optimizing thermal processes.

Crucial for power plants, boosting performance with stability.

Enhances air conditioning systems by improving thermal exchange.

Perfect for compressor coolers, ensuring optimal cooling performance.

KL Footed Fin / Knurled L Footed Fin

The KL fin is renowned as the knurled L fin, offering unique features. This innovative finned tube mirrors the Wrap-On fin in form and is meticulously crafted using both Wrap-On and Embedded techniques. Fins are expertly fashioned from strips molded into an L shape akin to the L type, then adeptly rolled into a taper that encourages curling. This design is skillfully helically wound onto the tube in a continuous loop under tension, ensuring a secure fit. The tube is embraced by the fin, providing enhanced contact and efficiency. A precision spinning tool knurls the base tube, integrating the foot of the fin into the knurling of the base tube for a robust bond and superior thermal performance.

 

By utilizing the correct fin strip, each fin aligns perfectly with the next without gaps, forming a seamless protective layer. This meticulous design significantly shields the tube from corrosion. Fins are securely fastened at each end in a manner similar to L fins, preventing any unwinding and maintaining stability. KL -Foot tension wound finned tubes are predominantly employed in metal applications, delivering unmatched performance. Withstands up to a remarkable 320°C (608°F), demonstrating exceptional durability.

Advantages:

Boasts corrosion-resistant tubes, ensuring long-lasting integrity.

Engineered with vibration resistance for reliable performance.

Capable of enduring temperatures as high as 320°C (608°F), affirming its robustness.

Combines high thermal performance and stress resistance with formidable protection against air corrosion, creating an unparalleled solution.

KL fins serve as a versatile replacement for any form of finned tube, offering flexible application.
 

LL-Foot Fin / Overlapped L

 

Fins are crafted from strips similarly to the L type; however, the foot is intricately shaped into a stepped double L, then rolled to curl, providing a strategic advantage. The LL-Foot Fin - Overlapped L is meticulously helically coiled onto a tube under tension, creating a seamless fit. The fin clings tightly to the tube, with each fin overlapping the foot of the next, ensuring complete coverage and protection. Such design ensures the tube is thoroughly shielded from corrosion, enhancing longevity and performance. In environments where corrosion poses a significant threat, this specific type of tube emerges as a highly favored choice. It stands out as a cost-effective alternative to the pricier extruded fin variant, offering similar performance benefits without the steep investment.

 

The fins are ingeniously secured at each extremity, mirroring the reliable method employed in securing L-type fins. This ensures stability and optimal performance throughout its use. This LL-type fin tube is engineered to withstand high temperatures, accommodating conditions that soar up to a blazing 350 degrees Fahrenheit (177°C).
