Introducing our Laser Welded Finned Tube / Stainless Steel Finned Pipe, engineered with precision for superior heat exchange, tailored for unmatched thermal efficiency. Meticulously crafted, this cutting-edge product ensures extraordinary heat transfer performance and enhanced cooling capabilities.
Featuring solid or serrated fins, delicately helically wound and seamlessly welded by an advanced automatic laser finning machine. Our revolutionary laser finning process guarantees an impeccable fin-to-tube bond with reduced heat input, maximizing heat flow and elevating corrosion resistance.
Advantage
This innovation significantly surpasses the performance of traditional MAG/HF welding techniques, offering pivotal advantages.
The robust connection between fins and the base tube promotes outstanding heat transfer, achieving up to 2.5 times the thermal efficiency of conventional finned tubes.
The uninterrupted weld eliminates notch effects, effectively preventing corrosion and crack formation, even in oscillating finned tubes.
Minimal base metal heating during welding and rapid travel speeds of up to 20m/min. drastically reduce the heat-affected zone in the base tube. This process ensures no complete melting of the tube occurs, thus avoiding metallurgical transformation of the parent metals.
Description
· Thin, continuous weld seam
· Minimized heat-affected zone
· Negligible discoloration at the weld site
· Minimal microstructural alterations in tube and fin
· High heat utilization for seam formation
· Enhanced safety by preventing crevice corrosion due to high weld integrity
· No weld seam impurities, thanks to laser-welding in a protective atmosphere
