Discover the unmatched engineering of our Laser Welded Finned Tube/Stainless Steel Finned Pipe—a pinnacle of heat exchanger technology crafted for superior performance in demanding environments. Expertly engineered for precision, this product ensures exceptional heat transfer and optimal cooling efficiency, setting new standards in thermal management.
Our fins, available in solid or serrated profiles, are meticulously helically wound and seamlessly laser-welded to the tube by an advanced, fully automated machine, ensuring unparalleled quality. Revolutionizing the industry, our innovative laser finning process establishes an ideal fin-to-tube bond, significantly minimizing heat input while maximizing heat flow efficiency and bolstering corrosion resistance.
Advantage
In the realm of welding, our technology stands out with critical advantages over traditional MAG/HF methods.
The seamless integration of fins to the base tube results in superior heat transfer and a phenomenal enhancement in thermal performance—up to 2.5 times greater than conventional finned tubes.
Our continuous welding technique eradicates notch effects, thereby dramatically reducing the risk of corrosion and the development of cracks, even under variable conditions.
With minimal base metal heating and high-speed travel of up to 20m/min, our process effectively limits the heat-affected zone, preserving the integrity of the base tube. Our method ensures complete exclusion of tube melting and prevents any metallurgical transformation of the parent metals, maintaining quality.
