| Product Description
PPR pipe (Polypropylene Random Copolymer Pipe) is manufactured from type III polypropylene through extrusion molding . Featuring high-temperature resistance (up to 95°C), excellent pressure tolerance, health safety, and leak-proof fusion connections, these pipes offer a service life of over 50 years. PPR pipes are widely used in building hot/cold water systems, purified water delivery, heating, and central air conditioning.
| Product Features
● Health & Environmental Safety: Made from eco-friendly polypropylene with no heavy metal additives, inhibits bacterial growth, safe for drinking water delivery.
● Leak-Proof Fusion Connection: Heat fusion creates an integrated joint between pipe and fitting, avoiding toxic adhesives.
● High Temperature & Pressure Resistance: Long-term operating temperature up to 70°C, momentary temperature up to 95°C, meeting demanding hot water requirements.
● Low Flow Resistance: Smooth inner walls prevent scaling, reducing flow resistance with 30% higher flow capacity than metal pipes of same diameter.
● Extended Service Life: Manufactured to standards, providing over 50 years of reliable performance under normal conditions.
● Excellent Thermal Insulation: Low thermal conductivity provides significant energy savings for hot water systems.

| FAQ
1. What do the S5, S4, S3.2 markings on PPR pipes mean?
● Answer: These are pipe series designations indicating wall thickness. S5 and S4 are cold water pipes (thinner wall, blue stripe); S3.2 and S2.5 are hot water pipes (thicker wall, red stripe) . For hot water systems, S3.2 or higher series must be used.
3. How do you check for leaks after PPR pipe installation?
● Answer: Conduct a pressure test: Seal all outlets, slowly fill with water to purge air, pressurize to test level (0.8-1.0MPa), and hold for 30 minutes. If pressure drop ≤0.05MPa with no visible leaks at joints, the system passes.
5. What are your delivery time for PPR pipes?
● Answer: Stock items ship within 7 working days; bulk orders in 15-25 working days depending on quantity. Volume discounts available—contact us for quotes.
