Plastic Pipes

Polypropylene Pipe – Overview

The Polypropylene Pipe (PP-R, Type III polypropylene) is a high-quality piping solution widely used in modern construction and industrial applications. Compared to traditional steel and copper pipes, this pipe offers multiple advantages, including hygiene, lightweight design, corrosion resistance, low flow resistance, thermal insulation, reliable connections, and recyclability. With a service life exceeding 50 years, it provides a long-term, durable solution for water supply and chemical transport systems.

Material and Specifications

• Pipe Series: S2.5, S3.2, S4, S5

• Nominal Outer Diameter: DN20mm–DN110mm

• Standard Length: 4 meters

• Color: White outer layer, green inner layer

• Markings:

  • S2.5 and S3.2 series: Red markings

Made from premium PP-R raw materials, the Polypropylene Pipe is non-toxic, chemically resistant, and environmentally friendly, ensuring safe and hygienic water delivery in both residential and industrial applications.

Key Features of Polypropylene Pipe

The Polypropylene Pipe combines modern material technology with practical design to provide a range of benefits:

1. Premium PP-R Material: Non-toxic, harmless, and highly resistant to chemical corrosion, ensuring safe and long-lasting operation.

2. Double-Layer Protection: The opaque double-layer structure blocks light, inhibiting the growth of algae and other microorganisms, even when pipes are exposed.

3. Smooth Inner Wall: Prevents scaling and reduces flow resistance, ensuring efficient water delivery and minimizing maintenance.

4. Durable and High-Temperature Resistant: Good toughness and stability allow operation at temperatures up to 70℃, meeting long-term usage demands.

5. Lightweight and Easy to Install: Simplifies transport, handling, and construction, reducing labor and overall installation costs.

6. Reliable Connections: Compatible with convenient and secure connection methods, ensuring leak-proof joints and long-term system integrity.

Applications of Polypropylene Pipe

The versatility of the Polypropylene Pipe makes it suitable for a wide variety of systems:

• Building Water Systems: Hot and cold water supply for residential and commercial buildings.

• Heating Systems: Radiator heating pipelines and central heating systems.

• Pure Water Supply: Drinking water pipelines and beverage production systems.

• Industrial Applications: Transport and discharge of chemical media in factories.

• HVAC Systems: Central air conditioning pipelines.

• Solar Energy Systems: Hot water and solar energy transport.

• Rainwater and Drainage Systems: Efficient rainwater collection and drainage.

By providing smooth flow, chemical resistance, and hygienic safety, the Polypropylene Pipe ensures reliable operation across multiple applications while reducing maintenance and energy consumption.

Advantages Over Traditional Piping

The Polypropylene Pipe offers clear advantages compared to steel or copper pipes:

• Corrosion resistance for longer service life

• Lightweight construction for easier handling and installation

• Smooth inner walls reducing scaling and pressure loss

• Opaque structure maintaining water hygiene

• Cost-effective and recyclable material

These advantages make the Polypropylene Pipe a high-quality, efficient, and economical solution for modern construction, industrial, and water transport systems.
