Introducing our expertly crafted Laser Welded Finned Tube/Stainless Steel Finned Pipe, the epitome of heat exchanger technology engineered for exceptional efficiency. Meticulously fashioned with unparalleled precision and craftsmanship, this product promises superior heat transfer and cooling capabilities.
Our fins, either solid or serrated, are intricately helically wound and seamlessly welded to the tube using a state-of-the-art, fully automatic laser finning machine. The innovative laser finning process achieves an immaculate fin-to-tube bond, employing reduced heat input to enhance heat flow efficiency and bolster resistance against corrosion.
Advantage
Our laser welding technology stands head and shoulders above traditional MAG/HF welding, offering transformative advantages that are crucial.
This seamless union between fins and base tube ensures outstanding heat transfer capability, boosting thermal performance of the finned tubes up to 2.5 times.
Thanks to the uninterrupted weld, notch effects are eliminated, and risks of corrosion or cracks are significantly minimized, even in oscillating finned tubes.
The minimal base metal heating during the welding process, coupled with travel speeds reaching up to 20m/min, effectively shrinks the heat-affected zone within the base tube. Consequently, complete melting of the tube and any metallurgical transformation of the parent metals are entirely avoided.
Description
· Seamlessly thin, continuous weld seam
· Minimized heat-affected zone
· Negligible discoloration at the weld site
· Minimal microstructural changes in tube and fin
· Optimal heat utilization for seam formation
· Enhanced safety by eliminating crevice corrosion, thanks to impeccable weld integrity between tube and fin
· Pristine weld seam purity, achieved by conducting laser welding under a protective atmosphere
