1. Material Properties of PPR Pipes

• PPR (Polypropylene Random Copolymer) is formed by copolymerizing propylene and ethylene monomers
• Unique molecular structure provides both rigidity and flexibility (Vicat softening point ≥131℃)
• Enhanced heat resistance through antioxidants and thermal stabilizers

2. High-Temperature Impact Mechanism

• Short-term exposure (below 95℃): Stable physical properties
• Long-term exposure (above 70℃): Focus on creep resistance and oxidation degradation
• Extreme temperature: Tolerates 110℃ briefly, continuous use below 95℃

3. Technical Advantages of IFAN PPR Pipes

• Uses Borealis RA130E raw material (top global PPR resin)
• Triple-layer co-extrusion structure (inner layer + reinforcing layer + outer layer)
• Complies with ISO 15874 drinking water standard
• 50-year service life guarantee (based on EN 805)

4. High-Temperature Performance Comparison

5. Installation Recommendations

1. Use matching ifan PPR fusion fittings (ensure welding depth)
2. Install fixed brackets every 3 meters on straight sections
3. Install automatic air vents at system apex
4. Recommend water temperature ≤70℃ for continuous use

6. Typical High-Temperature Applications

• Central heating systems (70-80℃ hot water)
• Solar thermal systems (tank to collector sections)
• Industrial cooling systems (≤95℃ heat transfer media)
• Underfloor heating (≤60℃ supply water)

7. Advantages Over Other High-Temp Pipes

• Compared to copper: 40% cost reduction, no electrochemical corrosion
• Compared to PB: 25% higher pressure resistance, better creep resistance
• Compared to PE-RT: 30℃ higher long-term heat resistance

8. IFAN’s Quality Assurance

• 100% hydrostatic testing for every batch
• Free thermal expansion calculation service
• Custom high-temperature piping solutions
• Nationwide 24-hour technical support
