'G' TYPE FIN TUBE (EMBEDDED FIN TUBE) - Precision-designed for optimal performance in demanding applications.
'L', 'LL', 'KL' TYPE FIN TUBE (WRAP AROUND FIN TUBE) - Crafted with meticulous attention to detail for superior heat transfer.
LASER WELDED FINNED TUBE - Cutting-edge technology delivering exceptional durability and robustness.
HIGH FREQUENCY WELDED FIN TUBE (Including Serrated Finned Tube) - Perfectly aligned with advanced welding techniques for enhanced strength and efficiency.
L-Foot Finned Tube
Engineered for exceptional efficiency and cost-effectiveness, the L-footed finned tubing delivers superior heat transfer even at reduced temperatures, ensuring optimal performance. The innovative L-shaped design securely holds the fins, capable of withstanding intense heat cycling and high-velocity air vibrations with unparalleled stability.
The L-Foot Finned Tube is available in the following exceptional fin variations:
Knurled Fin - This fin features an interference fit, with finely crafted mechanical knurling that firmly integrates the fin material to the tube wall surface.
LL Fin - The Double Overlap fin (often termed as double LL) offers comprehensive double strip thickness coverage, enveloping the entire base tube for superior performance.
Perforated L Fin - Enhanced with 'tear drop' slits around the helix, these perforations disrupt air flow for improved efficiency.
L-Foot Fin / Wrap-On Fin
L-Foot Tension Wound Finned Tubes Also recognized as Wrap-On Finned Tubes, these are expertly utilized in scenarios where temperatures remain below approximately 300 degrees Fahrenheit, offering reliable low-temperature applications with necessary tube wall protection. Comprising of thin aluminium fin strips meticulously wound helically around the tube circumference, L-Foot tension wound finned tubes embody precision and durability. A distinctive 'foot' is first crafted on one side of the fin strip, giving rise to the name L-Foot. Subsequently, the strip is bound tightly around the tube, with the foot making direct contact with the tube's outer surface, securing it in place. The short horizontal limb of each L fin remains in intimate contact with the base-tube surface, ensuring complete coverage. The tension exerted in the fin strip during wrapping ensures the fin foot is seated forcefully on the tube, cementing the fin securely in its position. L-footed finned tubing is designed for optimal heat transfer efficiency at reduced temperatures. The distinctive L-shaped design ensures fins remain steadfast, enduring rigorous heat cycling and high-speed air vibrations. This finning offers a certain level of atmospheric protection to the tube wall, safeguarding against corrosion. An expansive contact surface between the tube and finning significantly amplifies heat transfer capabilities. This fin design combines high efficiency with cost-effectiveness, making it an exceptional choice.
The fin ends are meticulously stapled to prevent the aluminium fin from unraveling, maintaining crucial contact between the fin foot and the tube. This continuous contact is vital for the air cooler's operation, facilitating efficient heat transfer from the tube wall through the fin to the surrounding air.
Compelling Advantages:
Ideal for low-temperature applications, ensuring versatile utility.
Among finning types, this is the most cost-effective method available, offering great value.
In case of fin failure, they can be effortlessly removed, allowing the bare tube to be seamlessly reused for further finning.
There is no necessity to create a helical groove over the core tube, simplifying the process.
Fins can be meticulously placed on an extremely thin-walled tube, which is particularly beneficial when expensive alloys are utilized as the core tube.
The tube boasts resilience to temperatures up to 130°C without risking atmospheric corrosion or thermal stress.
Diverse Applications Include:
Oil and Gas Refineries: Ensuring efficient heat management in critical processes.
Petroleum, Chemical, and Petrochemical Industries: Supporting rigorous industrial applications.
Natural Gas Treatment: Facilitating reliable gas processing operations.
Steel Making Industry: Enhancing thermal efficiency in metallurgical processes.
Power Plants: Aiding in robust and consistent power generation.
Air Conditioning: Elevating cooling solutions with superior heat transfer.
Compressor Coolers: Guaranteeing optimal performance in various cooling systems.
KL Footed Fin / Knurled L Footed Fin
The KL fin is also renowned as the knurled L fin, offering exceptional performance. Crafted with precision, this finned tube mirrors the Wrap-On fin, employing both Wrap-On and Embedded techniques for superior efficiency. Fins are meticulously crafted from strips shaped into an L configuration, rolled into a taper for enhanced curvature, akin to the L type. Subsequently, it is helically wound onto the tube in a seamless continuous loop under precise tension. The tube is meticulously embraced by the fin, ensuring a snug fit. An innovative spinning tool intricately knurls the base tube, allowing the fin's foot to mesh seamlessly with the knurling, ensuring a robust bond and amplified thermal efficiency.
Employing the appropriate fin strip ensures consecutive fin bumping, eliminating gaps and ensuring flawless coverage. This strategic design significantly shields the tube against corrosion. Similar to L fins, these fins are secured at both ends, effectively preventing unwinding and ensuring reliability. KL-Foot tension wound finned tubes are predominantly utilized in metal-involving applications. Capable of withstanding a maximum operational temperature of up to 320°C (608°F)
Advantages:
Corrosion-resistant Tubes
Exceptional vibration resistance
Demonstrates resilience at temperatures soaring up to 320°C (608°F).
Boasting high thermal performance, stress resistance, and air corrosion protection, this is an extraordinary combination.
KL fin tubes can seamlessly replace any conventional finned tube.
LL-Foot Fin / Overlapped L
Fins are crafted from strips, akin to the L type, with a meticulously controlled stepped double L shape, rolled into a taper for optimal curling. The LL-Foot Fin - Overlapped L is expertly coiled helically onto the tube under tension, ensuring durability. The fin envelops the tube, with each fin slightly overlapping the foot of the subsequent fin, ensuring comprehensive coverage of the base tube. This configuration provides the tube with exceptional corrosion protection. Ideal for corrosive environments, this tube serves as an economically viable alternative to more costly extruded-type fins.
Fins are meticulously secured at both ends, akin to L fins, ensuring stability. The LL-type fin tube is adept for environments with temperatures reaching up to 350 degrees Fahrenheit (177°C).
