PVC Pipe

PVC pipe is a plastic piping material made primarily from polyvinyl chloride resin, with added stabilizers, lubricants, and other additives, and is formed through extrusion. It features lightweight, good corrosion resistance, good insulation properties, and low fluid resistance. Based on application, it is categorized into types such as PVC-U pipes for drainage (gray), PVC-M pipes for water supply (blue), and electrical conduits (white). Specifications are indicated by outer diameter × wall thickness (e.g., Φ110×3.2 mm). PVC pipes are widely used in building water supply and drainage systems, electrical cable protection, agricultural irrigation, and chemical fluid transport. They are typically connected using solvent welding or rubber ring joints, allowing for quick and easy installation. With high construction efficiency, long service life (up to 50 years), and low maintenance costs, PVC pipes are commonly used plastic piping materials today—especially well-suited for replacing traditional metal pipes in corrosive environments.
