Introducing the expertly crafted Laser Welded Finned Tube / Stainless Steel Finned Pipe by Cangzhou Datang Steel Pipe Co., Ltd., an exceptional heat exchanger solution engineered to deliver peak performance and efficiency. Meticulously designed with advanced precision, this product ensures outstanding heat transfer and cooling capabilities for various applications.
The helically wound fins, available in both solid and serrated designs, are seamlessly and continuously welded to the tube using a state-of-the-art fully automatic laser finning machine. With our innovative laser finning process, experience an impeccable fin-to-tube bond that offers reduced heat input, heightened efficiency in heat flow, and superior corrosion resistance.
Advantage
The advantages over traditional MAG/HF welding are profoundly significant.
Achieving a complete bond between the fins and the base tube leads to exceptional heat transfer efficiency, offering up to 2.5 times the thermal performance of conventional finned tubes.
The continuous weld mitigates notch effects and prevents corrosion, thereby eliminating the risk of cracks, even under the stress of oscillating finned tubes.
Minimizing the heat-affected zone is achieved by low base metal heating during welding and a remarkable travel speed of up to 20m/min. Complete melting of the tube and any associated metallurgical transformation of the parent metals are effectively prevented.
Description
· thin, continuous weld seam
· minimal heat-affected zone
· barely noticeable discoloration at the weld site
· slight microstructural change in both tube and fin
· maximum heat utilization for seam formation
· enhanced safety due to the prevention of crevice corrosion through high weld integrity between tube and fin
· impurity-free weld seam ensured by conducting Laser-welding under a protective atmosphere
