Product Description

Product Parameters

Discover our diverse range of finned tubes designed to meet your every need: tension wound finned tubes, embedded finned tubes, and extruded finned tubes, each engineered with precision for optimal performance.

Our tension wound finned tubes are crafted with meticulous care, by tightly winding an aluminium or copper strip around the tube, ensuring enhanced efficiency and durability through maintained tension. Expertly utilizing strip winding technology, we offer a variety of fin types to suit your specific applications: the reliable L-Fin, the enhanced LL-Fin, and the innovative KL-Fin.

Embedded fins (G-Fins) are constructed by precisely winding an aluminium or copper strip into a helical groove, carefully machined on the tube's outer surface for superior heat exchange.

Whether you choose tension wound, embedded, or extruded finned tubes, they stand as the cornerstone of air coolers, finding their utility in numerous critical applications such as:

Power plant heat exchangers, spanning electric, nuclear, thermal, and geothermal sectors, ensuring efficient thermal management.

Integrated steam condensate systems, designed for optimal performance and reliability.

Serving the dynamically demanding chemical and petrochemical industries with precision-engineered solutions.

Food processing plants and advanced refrigeration technology, ensuring quality and safety at every step.

Robust solutions for industrial sectors including steel mills, incinerators, and gas compression facilities.

L-Foot Finned Tube

Our L-footed finned tubing is the epitome of efficiency and cost-effectiveness, designed to deliver maximum heat transfer even at lower temperatures. With its unique L-shaped configuration, this design ensures the fins remain firmly in place, resisting heat cycling and high-velocity air vibrations.

The L-Foot Finned Tube is available in several fin variations to meet specific application needs:

Knurled Fin - Featuring an interference fit, this fin type securely knurls the fin material to the tube wall, ensuring lasting stability and performance.

LL Fin - The Double Overlap fin, or double LL, provides comprehensive base tube coverage with double strip thickness, enhancing durability and efficiency.

Perforated L Fin - This innovative enhancement introduces 'tear drop' slits along the helix, disrupting airflow to optimize thermal transfer.

L-Foot Fin / Wrap-On Fin

L-Foot Tension Wound Finned Tubes also recognized as Wrap-On Finned Tubes, are expertly crafted for applications where temperatures are below 300 degrees Fahrenheit, offering essential tube wall protection in low-temperature settings. L-Foot tension wound finned tubes feature a tightly wrapped thin aluminium strip around the tube's circumference for optimal heat transfer. The 'foot' formed on one side of the fin strip gives the L-Foot its name, ensuring a secure fit. This strip is expertly wound, with the foot pressing firmly on the tube's surface, guaranteeing complete contact and stability. Each L's short horizontal limb ensures total base-tube surface coverage, maximizing efficiency. The inherent tension in the fin strip, as it wraps around the tube, ensures the fin foot is forcefully seated, maintaining firm contact and stability. L-footed finned tubing is a top choice for efficient heat transfer at lower temperatures. The robust L-shaped design keeps fins secure, withstanding heat cycling and the stresses of high-velocity air vibrations. This fin type also provides a layer of atmospheric protection against corrosion, prolonging the life of the tube. With the broad contact surface between tube and fin, heat transfer is significantly enhanced. This design is not only highly efficient but also cost-effective, providing superior value.

The fin ends are securely stapled, preventing unravelling and ensuring sustained contact between fin foot and tube. This essential contact ensures the effective operation of the air cooler by facilitating the seamless transfer of heat from the tube wall, across the fin, and into the ambient air.

Advantages:

Perfectly aligned for low-temperature applications, ensuring optimal performance.

This finning type stands out as the most economically efficient method available.

Failed fins are easily removed during production, allowing the bare tube to be reused for new finning.

Eliminates the need to create a helical groove on the core tube, simplifying the process.

Fins can be placed on tubes with thin walls, which is ideal when using costly alloys as the core tube, maximizing material efficiency.

The tube can endure temperatures up to 130°C, safeguarding against atmospheric corrosion and thermal stress.

Application:

Oil and gas refineries utilize this technology for enhanced efficiency.

Widely used across petroleum, chemical, and petrochemical industries for superior performance.

Critical to the natural gas treatment process for optimal results.

Integral to the steel making industry, supporting high-standard processes.

Essential in power plants, boosting energy conversion efficiency.

Vital for air conditioning systems, enhancing cooling effectiveness.

A key component in compressor coolers, ensuring reliable operation.

KL Footed Fin / Knurled L Footed Fin

The KL fin, commonly referred to as the knurled L fin, offers robust performance. This finned tube, akin to the Wrap-On fin, combines both Wrap-On and Embedded techniques for superior results. Crafted from strips formed into an L shape, the fins are then rolled into a taper, allowing them to curl. The fins are helically wound onto the tube in a continuous loop under tension, ensuring stability. The fin securely embraces the tube, providing a snug fit. A spinning tool intricately knurls the base tube, with the fin's foot knurled into the base tube's knurling, enhancing thermal efficiency and bonding strength.

With the correct fin strip, the foot of one fin aligns with the next, eliminating gaps and enhancing protection. This meticulous design guards the tube against corrosion, ensuring longevity. Similar to L fins, they are securely attached at each end to prevent unwinding, maintaining integrity. In metal-involved applications, KL-Foot tension wound finned tubes are the preferred choice. Engineered to operate flawlessly at temperatures up to 320°C (608°F).

Advantages:

Boasting corrosion-resistant tubes for enhanced durability.

Designed to resist vibrations, ensuring robust performance.

Capable of withstanding extreme temperatures of up to 320°C (608°F) with ease.

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

The KL finned tube is versatile, effortlessly replacing any existing finned tube type.

LL-Foot Fin / Overlapped L

Fins are crafted from strips, much like the L type, with the foot expertly shaped into a precisely controlled double L form, rolled to permit curling. The LL-Foot Fin - Overlapped L is meticulously helically coiled onto a tube under tension, ensuring a secure fit. The fin grips the tube, overlapping the foot of the adjacent fin, resulting in complete coverage and protection. This configuration provides exceptional corrosion resistance, safeguarding the tube. In corrosive environments, this tube serves as a cost-effective alternative to pricier extruded fin types.

Our innovative finned tube design ensures that fins are securely fastened at each end, mirroring the robust attachment seen in traditional L fins, providing enhanced durability and efficiency. The LL-type fin tube is meticulously engineered to withstand high temperatures, making it an ideal choice for applications requiring heat resistance up to 350 degrees Fahrenheit (177°C), ensuring long-lasting performance and reliability.
