Introducing our flagship product: the Laser Welded Finned Tube / Stainless Steel Finned Pipe—an extraordinary heat exchanger solution, crafted to perfection for outstanding performance and reliability in the most challenging environments. Carefully engineered with unmatched precision, this exceptional product elevates heat transfer and cooling efficiency to new heights, setting unprecedented industry standards.
Our cutting-edge fins, available in both solid and serrated designs, are expertly helically wound and seamlessly welded to the tubes using an advanced automatic laser finning machine, guaranteeing impeccable quality. Our state-of-the-art laser finning technology ensures a flawless fin-to-tube bond, minimizing heat input while dramatically boosting thermal efficiency and corrosion resistance.
Advantage
Our revolutionary approach offers substantial advantages over traditional MAG/HF welding techniques, redefining excellence and setting new benchmarks.
The impeccable bond between fins and base tube delivers exceptional heat transfer capabilities, achieving up to 2.5 times the thermal performance compared to conventional finned tubes.
The continuous welding process eradicates notch effects, effectively preventing corrosion and cracks in oscillating finned tubes, ensuring outstanding durability.
With minimal base metal heating during the welding process and rapid travel speeds reaching up to 20m/min, the heat-affected zone is significantly reduced, safeguarding the base tube's integrity. This process guarantees complete exclusion of tube melting and related metallurgical transformations, maintaining the original properties of the parent metals intact.
