Product Description

Product Parameters

Discover our diverse range of finned tubes, meticulously engineered for optimal performance: tension wound finned tubes, embedded finned tubes, and extruded finned tubes.

Tension wound finned tubes are expertly crafted by spirally wrapping a strip of premium-grade aluminium or copper around the tube under precisely controlled tension. Our state-of-the-art strip winding technology offers a variety of fin types, each tailored for specific applications: L-Fin, LL-Fin, and KL-Fin.

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

Mainstay in air cooler technology, these tension wound, embedded, and extruded finned tubes find extensive use across diverse sectors:

Heat exchangers for power plants, including electric, nuclear, thermal, and geothermal power facilities.

Comprehensive steam condensate systems.

Integral to the chemical and petrochemical industries.

Vital for food processing plants and advanced refrigeration technology.

Crucial for industrial operations, including steel mills, incinerators, and gas compression facilities.

L-Foot Finned Tube

Achieving unmatched thermal efficiency without breaking the bank, our L-footed finned tubing ensures peak heat transfer even at low temperatures. The distinctive L-shaped configuration secures the fins robustly, withstanding both heat cycling and high-velocity air vibrations effortlessly.

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

Knurled Fin - A high-precision interference fit fin, crafted with mechanical knurling to ensure superior adhesion between the fin material and the tube wall.

LL Fin - The Double Overlap fin, or double LL configuration, offers comprehensive double-strip thickness coverage over the entire base tube.

Perforated L Fin - Enhanced with strategically placed 'tear drop' slits around the helix, this fin breaks up airflow patterns for improved efficiency.

L-Foot Fin / Wrap-On Fin

L-Foot Tension Wound Finned Tubes Also known as Wrap-On Finned Tubes, these are ideal for applications where temperatures remain below approximately 300°F, providing essential low-temperature protection. These tubes feature a thin aluminium fin strip, expertly helically wound around the tube circumference for optimal performance. An initial 'foot' is meticulously crafted on one side of the fin strip, giving rise to the name L-Foot. The strip is then expertly wound around the tube, with the foot ensuring perfect contact with the tube's outer surface. The L's short horizontal limb ensures comprehensive coverage of the base-tube surface, maximizing efficiency. The tension applied during the winding process ensures the fin foot is firmly seated against the tube, maintaining its secure position. Our L-footed finned tubing is engineered for superior heat transfer, even at lower temperature ranges. The L-shaped design is specifically tailored to maintain fin rigidity, effectively resisting heat cycling and dynamic air vibrations. This innovative fin design also provides substantial atmospheric protection, shielding the tube wall from corrosion. The extensive contact surface between tube and fin enhances thermal conductivity for unmatched heat transfer efficiency. Offering exceptional efficiency at a cost-effective price point, this fin design is a smart choice for myriad applications.

Fins are securely stapled at the ends to prevent unravelling, maintaining vital contact between the fin foot and the tube. This crucial contact is fundamental to air cooler performance, facilitating the seamless transfer of heat from tube wall to ambient air.

Advantages:

Perfectly tailored for low-temperature applications, this product ensures top-tier performance in such conditions.

Among the various finning types, this method stands out as the most cost-efficient solution, maximizing value while minimizing expense.

The innovation in design allows for easy removal of faulty fins during production, enabling the bare tube to be reused seamlessly for finning again.

The process eliminates the need to craft a helical groove on the core tube, simplifying production and reducing costs.

Fins can be effortlessly attached to very thin-walled tubes, which is especially beneficial when working with precious and expensive alloy core tubes.

Remarkably, the tube can endure temperatures soaring up to 130°C, all while resisting atmospheric corrosion and avoiding thermal stress.

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 alternatively recognized as the knurled L fin, offering a versatile solution. This exceptionally engineered finned tube mirrors the characteristics of the Wrap-On fin, crafted using both Wrap-On and Embedded techniques for enhanced utility. These fins are ingeniously manufactured from strips shaped into an L form, akin to the L type, then artfully rolled into a taper that encourages curling. Subsequently, the fins are helically wound onto the tube, creating a continuous loop under controlled tension for optimal fit. The fin embraces the tube closely, ensuring a snug and secure fit. A sophisticated spinning tool intricately knurls the base tube, allowing the fin's foot to interlock with this knurling, thus attaining a robust bond and superior thermal conductivity.

Proper fin strip utilization ensures each fin's foot meets the next seamlessly, eliminating gaps and enhancing structural integrity. This robust design significantly enhances tube protection against corrosion, extending its lifespan. Similar to the L fins, these fins are fastened at each end, preventing any unwinding and ensuring long-term reliability. These KL-Foot tension wound finned tubes are commonly employed in metal-related applications, where they prove exceedingly effective. These tubes are designed to perform at a maximum operating temperature of up to 320°C (608°F), showcasing remarkable heat resilience.

Advantages:

Corrosion-resistant Tubes

Exceptional vibration resistance

Capable of withstanding extreme temperatures up to 320°C (608°F), showcasing its robust thermal endurance.

Combining high thermal performance and stress resistance with air corrosion protection, this product offers a unique and unmatched package.

The versatility of the KL fin allows it to replace any existing finned tube, offering flexibility and performance enhancements.

LL-Foot Fin / Overlapped L

Crafted from strips, the fins are akin to the L type but with an advanced double L-shaped foot, precisely rolled into a taper for superior curling. The LL-Foot Fin - Overlapped L is carefully helically coiled onto the tube under tension, promoting unrivaled efficiency. This innovative design ensures the fin grips the tube securely, with each fin overhanging the next, thoroughly covering the base tube. As a result, the tube is superbly shielded from corrosion, significantly enhancing its durability and performance. In environments prone to corrosion, this tube is a cost-effective alternative to pricier extruded fin types, delivering exceptional value.

Following the same secure methodology as L fins, these fins are affixed at both ends, ensuring unwavering stability and dependability. The LL-type fin tube is meticulously designed to withstand temperatures reaching up to 350 degrees Fahrenheit (177 degrees Celsius). This robust capability ensures reliable performance even in demanding thermal environments, making it a versatile choice for various heat transfer applications.
