Our state-of-the-art production facilities are equipped to manufacture an extensive range of finned tubes, including the following distinguished types:
EXTRUDED FIN TUBE (Featuring both Bimetallic Fin Tube & Integral Low Fin Tube)
'G' TYPE FIN TUBE (Crafted as Embedded Fin Tube)

HIGH FREQUENCY WELDED FIN TUBE (Also offering Serrated Finned Tube options)
L-Foot Finned Tube
Engineered for excellence, the L-footed finned tubing combines remarkable efficiency with cost-effectiveness, delivering unparalleled heat transfer capabilities even at reduced temperatures. Boasting a distinctive L-shaped architecture, these fins are securely anchored to endure dramatic heat cycling and the vibrations of high-velocity air.
The versatile L-Foot Finned Tube is available in several fin variations, ensuring adaptability to diverse requirements:
Knurled Fin - Features an interference-fit design with precisely knurled fin material that bonds seamlessly to the tube wall surface.
LL Fin - The Double Overlap fin, or LL fin, offers a robust double-layered thickness, enveloping the entire base tube with enhanced durability.
Perforated L Fin - Innovatively designed with 'tear drop' slits on the helix, this variation disrupts airflow for improved performance.
L-Foot Fin / Wrap-On Fin
L-Foot Tension Wound Finned Tubes Commonly referred to as Wrap-On Finned Tubes, these are ideal for applications where temperatures peak around 300°F, offering reliable tube wall protection for low-temperature scenarios. This design utilizes a thin aluminium fin strip, meticulously wound in a helical pattern around the entire circumference of the tube. The process begins by forming a 'foot' on one edge of the fin strip, aptly giving the L-Foot its name. The strip is then securely wrapped around the tube, ensuring the foot maintains direct contact with the outer surface of the tube. Every short horizontal section of the L makes complete contact with the base tube, fully encasing it. The tension applied during wrapping ensures the fin foot is tightly seated on the tube, maintaining the fin's position steadfastly. This finned tubing excels in maximizing heat transfer efficiency even at lower temperature ranges. The unique L-shaped design ensures the fins remain stable, withstanding both thermal cycling and high-speed air vibrations. Designed to offer substantial protection against atmospheric corrosion, this fin secures the tube wall integrity. The expansive contact interface between the tube and the fin optimizes thermal conductivity, enhancing overall heat transfer. This ingenious fin design is celebrated for its exceptional efficiency and economic viability.
To ensure durability, the ends of the fins are stapled, preventing the aluminium fin from unravelling and losing its crucial contact with the tube. This contact is vital for the seamless function of air coolers, as it facilitates efficient heat transfer from the tube wall through the fin to the ambient air.
Advantages:
Perfectly suited for low-temperature applications, providing reliable performance.
This type of finning presents the most economical option when compared to alternative methods.
Easily removable failed fins allow for the base tube to be reused, maintaining production efficiency.
No necessity for machining a helical groove on the core tube enhances simplicity and reduces cost.
Capable of accommodating fins on ultra-thin-walled tubes, especially valuable with expensive alloy core tubes.
The tube is engineered to endure temperatures up to 130°C without succumbing to atmospheric corrosion or thermal stress.
Application:
Oil and gas refineries are ideal venues for these tubes, enhancing operational efficiency.
Widely utilized across petroleum, chemical, and petrochemical industries due to their excellent performance.
Natural gas treatment facilities leverage these tubes for optimal processing efficiency.
Indispensable in the steel-making industry, enhancing productivity and reliability.
Crucial for power plants, ensuring efficient energy transfer and system integrity.
Air conditioning systems benefit from their superior heat transfer and reliability.

KL Footed Fin / Knurled L Footed Fin
The KL fin is also known as the knurled L fin. This exceptional finned tube mirrors the Wrap-On fin design, crafted with a blend of both Wrap-On and Embedded techniques. Our fins originate from meticulously prepared strips, elegantly shaped into an L configuration, akin to the classic L type, then artistically rolled into a taper resulting in an exquisite curl. The fin is then masterfully helically wound onto the tube in a seamless, continuous loop under precise tension. This process ensures that the tube is embraced snugly by the fin. A precision spinning tool knurls the base tube, allowing the foot of the fin to intricately engage with the knurling, forming an impeccable bond and elevating thermal efficiency.
When utilizing the perfect fin strip, each fin foot seamlessly meets the next, ensuring there are no gaps, creating an uninterrupted surface. This technique is pivotal in safeguarding the tube against corrosion. Similar to L fins, each end of the fins is securely fastened to prevent any unwinding. In metal-centric applications, KL-Foot tension wound finned tubes are predominantly favored. Capable of withstanding a maximum operating temperature of up to 320°C (608°F)
Advantages:
Corrosion-resistant Tubes
Excellent Vibration Resistance
These finned tubes can endure extreme temperatures, up to 320°C (608°F), with ease.
This unique blend of high thermal efficiency, superior stress resistance, and protection against air corrosion is unparalleled.
KL finned tubes offer a versatile replacement for any existing finned tube design.
LL-Foot Fin / Overlapped L
Crafted with precision, the fins are formed from strips akin to the L type but with a meticulously controlled stepped double L foot, rolled into a taper to facilitate curling. The LL-Foot Fin, with its Overlapped L design, is then expertly coiled helically onto a tube under calculated tension. This ensures the fin clings closely to the tube, with one fin elegantly overhanging the foot of the subsequent fin, providing comprehensive coverage. Such design predisposes the tube to excellent protection against corrosion. In environments prone to corrosion, this tube serves as a cost-effective substitute for the pricier extruded fin type.
Ends of the fins are affixed in the same manner as traditional L fins to ensure stability. The LL-type fin tube is adept for applications involving temperatures up to 350°F (177°C).
