Quyen Aluminium is a prominent producer and supplier of aluminum welded pipes in Da Nang, Vietnam, providing durable and high-performance pipe solutions for multiple industrial and commercial uses. With state-of-the-art welding technology and rigorous quality control, the company has produced aluminium welded pipes across a broad spectrum of diameters, wall thicknesses, and alloy grades. Famous for their accurate dimensions, weld seam smoothness, and high surface finish quality, Quyen Aluminium’s welded pipes find applications in the construction, automobile, marine, HVAC, and structural engineering industries. The company maintains a consistent level of product quality and prompt delivery to domestic as well as international buyers.
Aluminium welded pipes are generally fabricated using alloys such as 6061, 6063, and 5083, which offer a satisfactory combination of strength, corrosion resistance, and weldability. The welding operation entails the joining of aluminium strips or sheets along a longitudinal seam to produce a robust, rigid pipe with consistent mechanical properties. The pipes have high thermal and electrical conductivity, medium to high tensile strength, and resistance to weathering and corrosion. The aluminium welded pipes are structurally rigid but very light in weight, with ease in handling and installation. They may also be anodized or coated for enhanced surface protection and beauty.
