PVC Water Supply Pipe

Product Introduction

PVC water supply pipes are rigid plastic pipes manufactured primarily from sanitary-grade polyvinyl chloride (PVC) resin, blended with additives such as stabilizers and lubricants, and formed through an extrusion process. These pipes are primarily used for the transport of potable water, tap water, industrial water, and water for agricultural irrigation. They are suitable for applications including building water supply systems, municipal water distribution, rural drinking water supply, and farmland irrigation projects. Product Features

1. Lightweight: With a density significantly lower than that of metal pipes, they are easier to transport, load, unload, and install.

2. Corrosion Resistance: Highly resistant to chemical media such as acids, alkalis, and salts; not prone to rusting.

3. Smooth Inner Surface: Offers low resistance to water flow and a low roughness coefficient; resistant to significant scale buildup over long-term use.

4. Easy Installation: Can be connected using methods such as solvent welding (bonding), rubber-ring socket joints, or flanges.

5. Long Service Life: Under normal operating conditions, the design service life can typically reach approximately 50 years.

6. Good Hygienic Properties: When used for drinking water, the pipes comply with relevant safety and hygiene standards for domestic water supply.
