Introducing our expertly crafted Laser Welded Finned Tube and Stainless Steel Finned Pipe—an exceptional heat exchanger solution engineered for superior performance and reliability. Meticulously crafted with precision and unparalleled expertise, this product ensures exceptional efficiency in heat transfer and cooling capabilities.
Our fins, whether solid or serrated, are helically wound and seamlessly welded to the tube using a state-of-the-art, fully automated laser finning machine. This revolutionary laser finning process creates an impeccable fin-to-tube bond, utilizing lower heat input while enhancing heat flow efficiency and corrosion resistance.
Advantage
The distinct advantages over traditional MAG/HF welding are critically significant.
The comprehensive connection between the fins and the base tube results in outstanding heat transfer and elevates the thermal performance of the finned tubes to up to 2.5 times higher.
The continuous weld effectively prevents notch effects, eliminating corrosion and crack formation, even in the presence of oscillating finned tubes.
Minimal base metal heating during welding, combined with high travel speeds up to 20m/min., significantly reduce the heat-affected zone in the base tube. Complete melting of the tube and associated metallurgical transformation of the parent metals are thus eliminated.
Description
· Thin, continuous weld seam for enhanced durability
· Minimized heat-affected zone for structural integrity
· Negligible discoloration at the weld site
· Slight microstructural alteration in both tube and fin
· Optimal utilization of heat for seam formation
· Enhanced safety by preventing crevice corrosion, ensuring high weld integrity between tube and fin
· Purity of the weld seam is maintained, as laser-welding occurs in a protective atmosphere ensuring no impurities
