Introducing our expertly crafted Laser Welded Finned Tube/Stainless Steel Finned Pipe—a premier heat exchanger solution engineered for unparalleled performance and efficiency. Meticulously designed with precision, this product ensures exceptional heat transfer and superior cooling capabilities.
Featuring helically wound fins, either solid or serrated, these are seamlessly and continuously welded to the tube by our cutting-edge, fully automatic laser finning machine. Our innovative laser finning process guarantees an impeccable fin-to-tube bond, achieving lower heat input and enhancing both heat flow efficiency and corrosion resistance.
Advantage
The benefits over traditional MAG/HF welding are significantly profound and impactful, setting new benchmarks in welding technology.
The seamless bond between the fins and the base tube results in outstanding heat transfer, elevating the thermal performance of finned tubes by up to 2.5 times.
The continuous weld eliminates notch effects, effectively preventing corrosion and crack formation, even under conditions of potential oscillation in the finned tubes.
By minimizing base metal heating during welding and achieving travel speeds of up to 20m/min, the heat-affected zone in the base tube is significantly reduced. This process ensures complete melting and related metallurgical transformations of the parent metals are rigorously avoided, maintaining structural integrity.
Description
· Produces a thin, continuous weld seam of impeccable quality
· Maintains a remarkably small heat-affected zone
· Achieves only slight discolouration at the weld site, preserving aesthetics
· Ensures only minor microstructural changes in both tube and fin
· Maximizes heat utilization for forming the seam with precision
· Enhances safety by eliminating crevice corrosion due to superior weld integrity between tube and fin
· Guarantees purity of the weld seam, as laser welding is conducted under a controlled protective atmosphere
