1. Введение

For B2B customers in the water supply and construction industries, selecting the right PPR pipe for drinking water systems is critical for safety, compliance, and long-term performance. This guide explores the key factors to consider, supported by technical data and real-world applications.

2. Key Requirements for Drinking Water Pipes

2.1 Material Safety

• Chemical Inertness: Non-reactive with chlorine, fluoride, and heavy metals
• Leaching Limits: TDS <0.1mg/L (WHO guideline: 500mg/L)
• Microbiological Resistance: ASTM G22 anti-microbial certification

2.2 Durability

• Temperature Range: 0°C to 95°C continuous use
• Pressure Ratings: PN10-PN25 for municipal systems
• Lifespan: 50+ years with proper installation

2.3 Compliance

• NSF/ANSI 61 (USA): Drinking water component safety
• EN 12201 (Europe): Material stability for 50 years
• WRAS (UK): System performance and safety
• KTW (Germany): Chemical migration limits

3. PPR Pipe Features for Drinking Water

3.1 Molecular Structure

• Random copolymerization of propylene and ethylene
• Non-polar matrix prevents chemical reactions

3.2 Welding Technology

• Hot-melt welding creates seamless, leak-free joints
• ISO 21307 certified welding procedures

3.3 UV Resistance

• Black PPR pipes with carbon black stabilizers
• Outdoor lifespan up to 15 years

4. Selection Criteria

4.1 Certification Compliance

• Look for NSF 61, EN 12201, and WRAS certifications
