Introducing our expertly crafted laser welded finned tube and stainless steel finned pipe, a premier heat exchanger engineered for unrivaled performance and efficiency. Meticulously designed and manufactured with unparalleled precision, this product ensures superior heat transfer and cooling effectiveness.
The innovative fins, whether solid or serrated, are helically wound and seamlessly welded onto the tube using a state-of-the-art automatic laser finning machine. This cutting-edge laser finning technique achieves an impeccable fin-to-tube bond with reduced heat input, enhancing heat flow efficiency and resistance to corrosion.
Advantage
The advantages of this revolutionary laser welding over traditional MAG/HF welding are transformative and pivotal to performance.
The comprehensive connection between the fins and the tube core delivers outstanding heat transfer capabilities, boosting thermal performance of the finned tubes by as much as 2.5 times.
The seamless welding eliminates notch effects, preventing corrosion and crack formation even in potentially oscillating finned tubes.
The minimal base metal heating during welding, coupled with a high-speed travel rate of up to 20m/min, significantly reduces the heat-affected zone in the base tube. This process prevents the complete melting of the tube and avoids any metallurgical transformation of the base metals.
Description
· Thin, uninterrupted weld seam for optimal integrity
· Minimal heat-affected zone ensuring material strength
· Hardly any discoloration at the weld site for a clean finish
· Negligible microstructural changes in tube and fin
· Maximized heat utilization for forming a robust seam
· Enhanced safety through the prevention of crevice corrosion due to superior weld integrity between tube and fin
· Weld seam free from impurities, thanks to laser-welding under a secure protective atmosphere
