Product Description

Product Parameters

Introducing our diverse range of finned tubes! We offer various options including tension wound finned tubes, embedded finned tubes, and extruded finned tubes.

 

Tension wound finned tubes are meticulously crafted by winding a strip, made from either aluminium or copper, around the tube under tension, ensuring a robust and reliable formation. Our advanced strip winding technology yields a variety of fin types, including the L-Fin, LL-Fin, and KL-Fin, each designed for optimal performance.

 

Embedded fins (G-Fins) are ingeniously crafted by winding an aluminium or copper strip into a helical groove that is precisely machined on the tube's outer surface.
 

Tension wound finned tubes, embedded finned tubes, and extruded finned tubes are pivotal components in air coolers, commonly applied in:

 

Heat exchangers across various power plants, including electric, nuclear, thermal, and geothermal plants,

Steam condensate systems,

The dynamic chemical and petrochemical industry,

Food processing plants and cutting-edge refrigeration technology,

Industrial sectors such as steel mills, incinerators, and gas compression facilities.

 

L-Foot Finned Tube

 

Our L-footed finned tubing is a marvel of efficiency and cost-effectiveness, providing exceptional heat transfer at lower temperatures. With its distinctive L-shaped design, it holds the fins rigidly, expertly withstanding both heat cycling and high-velocity air vibration.

We offer the L-Foot Finned Tube in the following innovative fin variations:

 

Knurled Fin - A sophisticated interference fit type fin, featuring mechanical knurling of the fin material to the tube wall surface for enhanced performance.

LL Fin - The Double Overlap fin (the double LL) provides comprehensive double strip thickness coverage of the entire base tube.

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

 

L-Foot Fin / Wrap-On Fin

L-Foot Tension Wound Finned Tubes also known as Wrap-On Finned Tubes, are expertly utilized in low-temperature applications where temperatures do not exceed about 300 degrees Fahrenheit, providing essential tube wall protection. L-Foot tension wound finned tubes feature a thin aluminium fin strip meticulously and tightly wound helically around the tube circumference. A 'foot' is initially formed on one side of the fin strip, giving rise to the term L-Foot. Subsequently, the strip is wound tightly around the tube, with the foot making solid contact with the tube's outer surface. The short horizontal limb of each L remains in constant contact with the base-tube surface, ensuring full coverage. The tension in the fin strip, as it is wrapped around the tube, effectively seats the fin foot with force on the tube, securely holding the fin in place. L-footed finned tubing delivers maximum heat transfer efficiency at lower temperatures. Its distinct L-shaped design holds the fins firmly in place, expertly withstanding both heat cycling and high-velocity air vibration. This fin design also offers a degree of atmospheric protection for the tube wall against corrosion. The extensive contact surface between the tube and the finning significantly enhances heat transfer. This innovative fin design is not only highly efficient but also cost-effective.

 

To prevent the aluminium fin from unraveling and losing contact between the fin foot and the tube, the ends of the fins are stapled securely. This component is essential for optimal air cooler performance, facilitating efficient heat transfer from the tube wall to ambient air through the fin.

 

Advantages:

Ideal for low-temperature applications, ensuring versatility and robust performance.

This finning type offers the most cost-effective solution compared to alternative methods.

Failed fins can be effortlessly removed during production, allowing the reuse of the bare tube for further finning.

No need to create a helical groove on the core tube, simplifying the manufacturing process.

Fins can be mounted on very thin-walled tubes, especially beneficial when using costly alloys as the core tube.

The tube is capable of withstanding temperatures up to 130°C, effectively resisting atmospheric corrosion and thermal stress.

 

Application:

Perfect for oil and gas refineries, boosting efficiency and reliability.

Essential in petroleum, chemical, and petrochemical industries, enhancing process efficacy.

Vital for natural gas treatment, ensuring seamless operations.

A key player in the steel-making industry, optimizing production capabilities.

Integral to power plants, improving energy efficiency and output.

Useful in air conditioning systems, providing superior cooling performance.

Ideal for compressor coolers, ensuring optimal operational conditions.

KL Footed Fin / Knurled L Footed Fin

The KL fin is also referred to as the knurled L fin. This finned tube is akin to the Wrap-On fin, crafted using both Wrap-On and Embedded techniques for enhanced durability. Fins are fabricated from strips shaped into an L profile, then rolled to form a taper, naturally curling during processing. They are helically wound onto the tube in a continuous loop under tension for a secure fit. The fin embraces the tube intimately, ensuring firm contact. A spinning tool knurls the base tube, integrating the fin's foot into the knurling for a tight bond and superior thermal performance.

 

When the correct fin strip is used, the foot of each fin neatly abuts the next, eliminating gaps. This design significantly enhances the tube's resistance to corrosion. Fins are secured at each end, similar to L fins, preventing unwinding. KL-Foot tension wound finned tubes are typically used in metal applications due to their robustness. Capable of operating at temperatures up to 320°C (608°F), ensuring high performance under stress.

Advantages:

Corrosion-resistant Tubes

Offers excellent vibration resistance, maintaining stability in dynamic environments.

Withstands temperatures up to 320°C (608°F), providing superior thermal durability.

Combines high thermal performance and stress resistance with exceptional protection from air corrosion, a unique advantage.

KL fins can replace any form of finned tubes, ensuring flexible adaptability.
 

LL-Foot Fin / Overlapped L

 

Fins are made similarly to the L type, with the foot crafted into a precise double L shape, rolled to achieve a curling taper. The LL-Foot Fin - Overlapped L is then helically coiled onto the tube under tension for a perfect fit. The fin firmly clings to the tube, with each foot skillfully overlapping the previous one, ensuring complete coverage. This design provides exceptional corrosion protection for the tube. Often used as a cost-effective alternative to expensive extruded type fins in corrosive environments.

 

Our exceptional G Type Embedded Finned Tube design securely fastens fins at each end with the same robust precision as found in L fins, ensuring unparalleled stability and performance. Demonstrating remarkable resilience, the LL-type fin tube is engineered to withstand temperatures soaring up to 350 degrees Fahrenheit (177 degrees Celsius), making it an ideal choice for demanding thermal applications.
