Introducing Our Skillfully Manufactured Laser Welded Finned Tube / Stainless Steel Finned Pipe, a premium heat exchanger marvel, meticulously crafted for superior performance and efficiency. Engineered with unparalleled precision and expertise, this finned tube ensures outstanding heat transfer and unmatched cooling capabilities.
Featuring fins, either solid or serrated, these are helically wound and seamlessly welded to the tube by an advanced, fully automatic laser finning machine. Our innovative laser finning process achieves an impeccable fin-to-tube bond, minimizing heat input while enhancing efficiency, heat flow, and corrosion resistance.
Advantage
Our method boasts decisive advantages over conventional MAG/HF welding techniques.
The robust connection between fins and base tube facilitates exceptional heat transfer, achieving up to 2.5 times greater thermal performance.
The continuous weld effectively prevents notch effects, corrosion, and crack formation, even under oscillating conditions.
Minimal base metal heating during welding, coupled with a high travel speed of up to 20m/min, significantly reduces the heat-affected zone. Complete melting and metallurgical transformation of the tube's parent metals are expertly avoided.
Description
· Thin, continuous weld seam
· Minimal heat-affected zone
· Slight discolouration at weld site
· Marginal microstructural change in tube and fin
· Optimal heat utilization for seam formation
· Enhanced safety by preventing crevice corrosion through high weld integrity between tube and fin
· Weld seam purity ensured by laser-welding under a protective atmosphere
