The rigid polyvinyl chloride (PVC-U) building drainage rainwater pipe and pipe fittings are made of polyvinyl chloride resin as the main raw material, using high-quality additives, through scientific compounding, extrusion or injection molding. The product structure is designed reasonably and beautifully. The pipe fittings are compact and scientific in size, reliable in connection, and easy to operate and install. They are widely used in drainage rainwater systems for civil engineering buildings.
