PPR, short for Polypropylene-Random, is commonly known as Type 3 polypropylene. It represents an advanced alternative to traditional water supply materials like galvanized steel pipes, UPVC, aluminum-plastic, PE, PE-X, and PE-RT pipes. By using random copolymerization technology, PPR ensures excellent strength and heat resistance, making it the preferred choice for modern plumbing systems. Many people are still unsure about the **price of PPR water pipes**, so let's take a closer look at what they offer.
**Features of PPR Water Pipes**
PPR pipes, also known as random copolymer polypropylene pipes, are manufactured through extrusion and injection molding. Developed in Europe in the early 1990s, these pipes are known for their impact resistance and long-term creep performance. In addition to being lightweight, corrosion-resistant, and non-scaling, they have several key advantages:
1. **Non-toxic and Hygienic**: Made from carbon and hydrogen only, PPR is safe for both hot and cold water systems, even for drinking water.
2. **Excellent Heat Insulation**: With a thermal conductivity of 0.21 W/m·K, PPR is much more efficient than metal pipes.
3. **High Heat Resistance**: The Vicat softening point reaches 131.5°C, allowing it to handle temperatures up to 95°C for hot water systems.
4. **Long Lifespan**: Under normal conditions, PPR can last over 50 years under 70°C and 1 MPa pressure, and even longer at lower temperatures.
5. **Easy Installation**: PPR pipes can be joined using hot-melt or electric fusion techniques, ensuring strong and reliable connections.
6. **Recyclable Material**: PPR waste can be recycled into new products without compromising quality.
**Common Specifications of PPR Water Pipes**
PPR pipes come in various sizes, with common domestic specifications including 20mm, 25mm, and 32mm. These are typically categorized into S3.2 and S2.5 series for hot water use, while S4 and S5 are used for cold water. Hot water pipes often have a red line marking for easy identification. Cold water pipes should not be used for hot water due to differences in wall thickness.
**How to Choose and Buy PPR Pipes**
When purchasing PPR pipes, it's important to check the product label. Look for "random copolymer polypropylene pipe for cold and hot water" or "PP-R pipe for cold water" along with the standard GB/T 18742-2002. Be cautious of counterfeit products that may use inferior materials like PPB instead of PPR, which can lead to leaks and failures over time.
