PP-R Pipe FAQs
What is the maximum temperature PP-R pipes can withstand?
Our PP-R pipes can continuously operate at temperatures up to 95°C (203°F) with a maximum short-term tolerance of 110°C (230°F) for emergency situations. For hot water applications, we recommend using PN20 or PN25 rated pipes for optimal performance under thermal stress. The material maintains excellent mechanical properties across this temperature range without deformation or degradation.
Are PP-R pipes suitable for drinking water systems?
Absolutely. Our PP-R pipes are certified for potable water applications according to NSF/ANSI 61 standards. The material is naturally resistant to bacterial growth and doesn't leach harmful substances into the water. Unlike metal pipes, PP-R won't corrode or develop scale buildup that can affect water quality. We use food-grade raw materials that meet all international health and safety regulations for drinking water systems.
How do PP-R pipes compare to traditional metal pipes?
PP-R pipes offer several advantages over metal pipes. They are lightweight (about 1/9th the weight of steel), corrosion-free, and have superior thermal insulation properties (15 times better than copper). Installation is faster with heat fusion joints that create permanent, leak-proof connections. Unlike metal pipes, PP-R won't suffer from pitting, electrolytic corrosion, or mineral deposits. The smooth interior surface maintains consistent water flow with minimal pressure loss over time.
Installation Guidelines
Proper installation is crucial for maximizing the performance of PP-R piping systems. We recommend using professional heat fusion tools with temperature control between 260-280°C. Allow at least 2 minutes cooling time for each joint before pressure testing. Always account for thermal expansion (0.15mm/m/°C) when designing long runs. For outdoor applications, use UV-resistant sleeves or paint to protect against sunlight degradation.
