Product Description

Product Parameters

We offer a versatile collection of finned tubes, including tension wound, embedded, and extruded finned tubes to suit diverse industrial needs.

Our tension wound finned tubes are meticulously engineered by tightly winding a strip of premium aluminium or copper around the tube, ensuring optimal tension for peak performance. Our state-of-the-art strip winding technology enables the creation of various fin types, such as the L-Fin, LL-Fin, and KL-Fin, each offering unique advantages.

Embedded fins (G-Fins) are expertly crafted by spirally winding aluminium or copper strips into a precision-engineered helical groove on the tube's exterior surface.

These finned tubes, including tension wound, embedded, and extruded types, are essential components in air cooler systems and are widely utilized across several industry sectors:

Thermal power plants, including electric, nuclear, and geothermal, benefit from our heat exchangers, ensuring efficient energy transfer and operation.

Steam condensate systems rely on our advanced technology to maintain optimal functionality and efficiency.

The chemical and petrochemical industries depend on our finned tubes for robust performance in demanding environments.

Food processing plants and refrigeration technology leverage our products to maintain precise temperature control and efficiency.

Our solutions are indispensable in industrial applications such as steel mills, incinerators, and gas compression facilities, ensuring reliability and superior performance.

L-Foot Finned Tube

Our highly efficient yet economically viable L-footed finned tubing guarantees exceptional heat transfer even at reduced temperatures, providing an excellent cost-to-performance ratio. With its innovative L-shaped design, the L-Foot Finned Tube ensures the fins are securely held, minimizing the effects of heat cycling and high-speed air vibrations.

Available in various fin options, the L-Foot Finned Tube is customizable to meet specific operational requirements:

Knurled Fin - Features a mechanical knurling that forms an interference fit, enhancing the bond between the fin material and the tube wall for improved durability.

LL Fin - The double overlap (LL) design offers comprehensive coverage with enhanced thickness, safeguarding the entire base tube for increased longevity.

Perforated L Fin - Innovatively designed with 'tear drop' slits along the helix, this fin breaks up air flow efficiently, optimizing the cooling process.

L-Foot Fin / Wrap-On Fin

L-Foot Tension Wound Finned Tubes also known as Wrap-On Finned Tubes, are ideal for applications where temperatures are kept below 300 degrees Fahrenheit, providing essential wall protection in lower-temperature environments. This design features a thin aluminium fin strip, expertly wound helically around the tube, ensuring a tight and secure fit. The fin strip is initially shaped to form an 'L' foot, which securely anchors the strip as it wraps around the tube. The 'foot' of the strip firmly engages with the tube's outer surface, ensuring maximum contact and stability. Each short horizontal limb of the 'L' lies flat against the tube's surface, providing comprehensive coverage and enhancing thermal efficiency. Tension applied during wrapping ensures the 'L-foot' fin is tightly seated against the tube, maintaining a steadfast grip even in challenging conditions. L-footed finned tubing excels in maximizing heat transfer efficiency while operating at lower temperatures. Its robust L-shaped configuration offers resilience against heat-induced cycling and high-velocity air vibration. This innovative fin design also offers a degree of protective shielding to the tube wall, reducing the risk of corrosion. The extensive contact area between the tube and the finning significantly boosts heat transfer capabilities. Renowned for its efficiency and cost-effectiveness, this fin design is an excellent choice for various applications.

The fin ends are meticulously stapled to prevent unwinding, maintaining the crucial contact between the fin foot and the tube for seamless operation. This steadfast contact is vital to the air cooler's function, facilitating the transfer of heat from the tube, through the fin, to the ambient air.

Advantages:

Perfectly suited for low-temperature applications, making it versatile and reliable in a variety of environments.

This finning type stands out as the most cost-effective method when compared to other alternatives.

Efficiently designed to allow easy removal of failed fins during production, enabling the bare tube to be reused for finning.

Ingeniously eliminates the need for creating a helical groove over the core tube, simplifying production.

Enables fin placement on an ultra-thin-walled tube, particularly ideal for using costly alloys as the core tube.

The tube boasts resilience, withstanding temperatures up to 130°C without succumbing to atmospheric corrosion or thermal stress.

Applications:

Oil and gas refineries, ensuring reliable heat transfer and efficiency.

Petroleum, chemical, and petrochemical industries, where precision and robustness are key.

Natural gas treatment, optimizing processing efficiency and safety.

Steel making industry, providing essential thermal management solutions.

Power plants, enhancing energy production through superior thermal exchange.

Air conditioning, delivering consistent and efficient climate control.

Compressor coolers, boosting performance and reliability in demanding conditions.

KL Footed Fin / Knurled L Footed Fin:

The KL fin is recognized as the knurled L fin, offering exceptional performance. This finned tube mirrors the Wrap-On fin, crafted using both Wrap-On and Embedded techniques, maximizing versatility. Fins are meticulously formed from strips into a comparable L shape, then expertly rolled into a taper to induce curling. The fin is then helically wound onto the tube in a seamless loop under precision tension. The tube is snugly embraced by the fin, ensuring secure attachment. A sophisticated spinning tool intricately knurls the base tube, where the fin's foot is seamlessly integrated, enhancing bond strength and thermal efficiency.

Utilizing the correct fin strip, the foot of each fin seamlessly aligns with the next, leaving no gaps, thereby optimizing protection. This formation shields the tube from corrosion, extending its lifespan. Fins are securely attached at both ends, as with L fins, preventing any unwinding, even under stress. KL-Foot tension wound finned tubes are favored in metal applications for their durability and performance. Designed to operate at temperatures reaching up to 320°C (608°F) without compromise.

Advantages:

Corrosion-resistant Tubes: Built to last, they resist corrosion effectively.

Vibration Resistance: Designed to endure vibrations, ensuring stability.

Withstands extreme temperatures of up to 320°C (608°F), ensuring reliability.

Combines superior thermal performance and stress resistance with air corrosion protection for unmatched reliability.

KL fins offer the flexibility to replace any finned tube variant, adding adaptability to its list of benefits.

LL-Foot Fin / Overlapped L:

Crafted from strips, similar to L type but with a precise stepped double L shape, rolled into a taper for optimal performance. Helically coiled under tension, the LL-Foot Fin - Overlapped L ensures a firm grip on the tube. The fin clings to the tube, overlapping the foot of the next fin, offering comprehensive coverage and protection. The tube is exceptionally protected from corrosion in this configuration, promoting longevity. In corrosive environments, this tube variant provides an economical alternative to pricier extruded fins.

Fins are secured at each end, akin to L fins, ensuring steadfast performance. The LL-type fin tube is a remarkable engineering marvel, ideal for managing temperatures soaring up to 350 degrees Fahrenheit (177°C).
