PVC (polyvinyl chloride) pipe is a plastic pipe made from polyvinyl chloride resin, with appropriate additives, stabilizers, and lubricants added, and then extruded at high temperatures. Due to its excellent chemical stability, corrosion resistance, and pressure resistance, PVC pipe is widely used in underground water supply systems, becoming an ideal alternative to traditional metal pipes. PVC pipe for underground water line, designed specifically for underground water supply projects, offers significant advantages such as lightweight, high strength, long life, and easy installation. It is suitable for urban tap water distribution, rural drinking water projects, and industrial water supply systems.
Product Features
Excellent Corrosion Resistance: PVC pipe is unaffected by soil acids and bases, electrochemical reactions, or microbial corrosion. It effectively prevents rust, a common problem in metal pipes, and maintains a smooth inner wall over time.
High Strength and Compressive Resistance: Made from high-quality PVC-U material, the pipe body exhibits excellent compressive and impact resistance, capable of withstanding underground soil pressure and certain external loads, making it suitable for use at various burial depths. Lightweight and Easy Installation: PVC pipe weighs only 1/5 the weight of a steel pipe of the same specification, making it extremely easy to handle, cut, and install, significantly reducing labor costs and construction time.
Smooth Inner Surface and Low Water Flow Resistance: The pipe’s smooth inner surface creates a low friction coefficient, effectively reducing head loss and improving water delivery efficiency.
Reliable Connections and Strong Sealing: Adhesive connections or rubber ring socket connections are available, providing a strong seal and preventing leakage, making it suitable for long-term underground use.
Weather Resistance and Long Service Life: PVC pipe is highly resistant to UV rays, humidity, and temperature fluctuations, allowing it to last over 50 years after burial with minimal maintenance costs.
PVC pipe for underground water lines: Applications
Urban water systems: Used in urban water supply trunk lines and branch pipelines, ensuring safe and stable water supply.
Rural drinking water projects: Lightweight and easy to lay, suitable for long-distance water transmission and mountainous water supply projects.
Agricultural irrigation systems: Suitable for farmland irrigation, sprinkler irrigation, and drip irrigation main networks, with excellent pressure resistance.
Industrial water transportation: Suitable for transporting factory cooling water and other non-corrosive liquids.
Residential and park underground water supply: Suitable for safe and hygienic underground water supply network installation in residential communities, self-built houses, and other areas.
Specifications and Standards
PVC pipe for underground water lines typically complies with international standards such as ASTM D1785, ISO 1452, or GB/T 10002.1. Common diameters range from 20mm to 630mm, and pressure ratings include PN6, PN10, PN12.5, and PN16. Pipes of varying specifications and wall thicknesses can be selected based on project requirements.
PVC pipe for underground water line installation and maintenance
PVC pipe for underground water line installation does not require large machinery. During construction, ensure the trench bottom is level, avoid sharp rocks from contacting the pipe body, and allow for thermal expansion and contraction. After gluing or socket joints are completed, a water pressure test should be performed to ensure a good seal. Because PVC pipe has a smooth surface and resists scaling, it requires virtually no cleaning or maintenance, resulting in extremely low operating costs.
Environmental and Economic Advantages
PVC pipe is recyclable and energy-efficient to produce, embracing green environmental principles. Compared to traditional cast iron or steel pipes, PVC pipe is less expensive and more efficient to install, significantly reducing the overall cost of water supply system construction.
PVC pipe for underground water lines, with its corrosion resistance, pressure resistance, lightweight design, and long life, has become one of the most popular underground water pipe materials in modern water supply projects. Whether in urban infrastructure construction or rural clean drinking water projects, PVC water supply pipe provides users with a safe, economical, and reliable long-term water supply solution.
