Introducing our expertly manufactured Laser Welded Finned Tube / Stainless Steel Finned Pipe, the pinnacle of heat exchanger technology engineered for superior performance. Meticulously crafted with unparalleled precision and know-how, this product ensures exceptional heat transfer and unparalleled cooling efficiency.
The fins, available in solid or serrated forms, are intricately helically wound and seamlessly welded to the tube using a fully automated laser finning machine. This revolutionary laser finning process achieves an impeccable fin-to-tube bond with minimized heat input, optimizing efficiency in heat conduction and enhancing corrosion resistance.
Advantage
The advantages over traditional MAG/HF welding are remarkably significant.
The perfect union between the fins and base tube facilitates outstanding heat transfer, offering up to 2.5 times greater thermal performance than conventional finned tubes.
The continuous weld eliminates notch effects, preventing corrosion and crack formation, even in cases of potential oscillating finned tubes.
Minimal base metal heating during welding and high travel speeds of up to 20m/min substantially reduce the heat-affected zone in the base tube. Complete melting of the tube and any metallurgical transformation of the parent metals are effectively prevented.
Description
· thin, uninterrupted weld seam
· minimal heat-affected zone
· slight discoloration at weld site
· minimal microstructural alteration in tube and fin
· maximized heat utilization for seam forming
· enhanced safety through prevention of crevice corrosion due to robust weld integrity between tube and fin
· weld seam purity ensured by Laser-welding under a protective atmosphere
