Presenting our exceptional Laser Welded Finned Tube / Stainless Steel Finned Pipe – a pinnacle in heat exchanging technology engineered for supreme functionality and peak performance. Meticulously engineered with top-tier precision and advanced craftsmanship, this product is your guarantee of superior heat transfer and outstanding cooling capabilities.
The helically wound fins, available in both solid and serrated forms, are expertly and continuously welded to the tube using a state-of-the-art, fully automated laser finning machine. Our revolutionary laser finning technology ensures a flawless fin-to-tube bond, resulting in minimized heat input, heightened efficiency in heat flow, and enhanced resistance to corrosion.
Advantage
Our laser welding process offers significant advantages over traditional MAG/HF welding methods, setting a new standard in performance and reliability.
The seamless integration between the fins and the base tube ensures superior heat transfer, achieving up to 2.5 times the thermal performance compared to conventional finned tubes.
The continuous weld design prevents any notch effects, thereby eliminating corrosion risks and crack formation even in conditions of oscillating finned tubes.
With minimal base metal heating during welding and rapid travel speeds of up to 20m/min, the heat-affected zone in the base tube is substantially reduced. This method precludes complete melting of the tube and avoids any related metallurgical transformation of the parent metals, safeguarding structural integrity.
Description
· Thin, continuous weld seam
· Minimally heat-affected zones for superior durability
· Subtle discoloration at the weld site, preserving aesthetic and structural integrity
· Minimal microstructural changes for both tube and fin, maintaining optimal strength and performance
· Maximized heat utilization in seam formation, enhancing efficiency
· Elevated safety due to the prevention of crevice corrosion thanks to high weld integrity between tube and fin
· Purity of the weld seam is ensured as laser welding is conducted under a protective atmosphere, preventing contamination
