1. Health, Safety, and Environmental Protection: Polypropylene is an environmentally friendly material, suitable for conveying drinking water.

2. The joints are heat-melted to form a single unit, ensuring 100% no leakage. Other materials use threaded connections, which have lesser water resistance, but also avoid the toxicity associated with adhesive bonding.

3. Low conveying resistance.

4. Prices are affordable and moderate.

5. Long service life; products manufactured and used in accordance with the national standard GB/T18742 can last up to 50 years.

PPR, short for Polypropylene Random Copolymer, is joined using heat-fusion techniques, featuring welding and cutting tools, and boasts high reliability. The pricing is also quite economical. It offers excellent thermal insulation properties and the pipe walls are extremely smooth! The general price ranges from 4 to 8 yuan per meter (for 4-inch pipes). This does not include the threaded connections for both the inner and outer ends.

PPR pipes, officially known as Random Copolymer Polypropylene pipes, are a commonly used type of water supply pipeline in residential construction projects.
