Introducing our Skillful Manufacture: the Laser Welded Finned Tube / Stainless Steel Finned Pipe. This premier heat exchanger is meticulously crafted to deliver unmatched performance and reliability. With precision engineering and exceptional craftsmanship, this innovative product ensures top-tier heat transfer efficacy and superior cooling capabilities.
Ingeniously, the fins—whether solid or serrated—are helically wound and seamlessly welded to the tube using an advanced, fully automatic laser finning machine. This groundbreaking laser finning technique achieves an impeccable fin-to-tube bond, characterized by minimal heat input, enhanced heat flow, and superior corrosion resistance.
Advantage
The prominent advantages over traditional MAG/HF welding methods are of paramount significance.
The robust connection between the fins and the base tube results in exceptional heat transfer, boosting the thermal performance of the finned tubes by up to 2.5 times.
The continuous weld eliminates notch effects and prevents corrosion and crack formation, even in the event of potentially 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 significantly reduced. Consequently, complete tube melting and metallurgical transformation of the parent metals are effectively avoided.
Description
· Seamlessly thin, continuous weld seam
· Minimized heat-affected zone
· Negligible discoloration at the weld site
· Minimal microstructural alteration to tube and fin
· High heat utilization for optimal seam formation
· Enhanced safety through crevice corrosion prevention due to superior weld integrity
· Pristine weld seam ensured by laser-welding in a protective atmosphere
