Product Description

Product Parameters

Our meticulously engineered Laser Welded Finned Tube / Stainless Steel Finned Pipe stands as a premier choice for heat exchangers, promising exceptional performance and unmatched efficiency. Manufactured with unparalleled precision and expertise, this product assures superior heat transfer and cooling efficiency, meeting the highest industry standards.

The fins, whether solid or serrated, are helically wound and seamlessly welded to the tube using a state-of-the-art automatic laser finning machine. Our innovative laser finning process ensures an impeccable fin-to-tube bond, minimizing heat input while maximizing efficiency in heat flow and resistance to corrosion.

Advantage

The benefits of our process significantly surpass traditional MAG/HF welding methods, offering groundbreaking advantages.

The seamless connection between the fins and base tube facilitates extraordinary heat transfer, achieving up to 2.5 times superior thermal performance.

The continuous weld effectively eliminates notch effects, preventing corrosion and crack formation, even under dynamic conditions.

The minimal base metal heating during welding and the rapid travel speed, reaching up to 20m/min, significantly reduce the heat-affected zone in the base tube. Complete melting of the tube and any consequent metallurgical transformation of the parent metals are reliably prevented.

Description

· Thin, continuous weld seam

· Minimal heat-affected zone

· Negligible discolouration at the weld site

· Insignificant microstructural alteration in tube and fin

· Optimal heat utilization for seam formation

· Enhanced safety by eliminating crevice corrosion due to superior weld integrity between tube and fin

· Weld seam purity is assured, as laser welding is conducted under a protective atmosphere
