What is the Stability of IFAN PPR Pipes in High-Temperature Environments?

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

Test ItemIFAN PPR PipeStandard PPR PipeMetal Pipe
Long-Term Temp70℃ @ 1.0MPa60℃ @ 0.8MPa120℃+
Short-Term Pressure95℃ @ 1.5MPa85℃ @ 1.2MPa150℃+
Linear Expansion0.15mm/m·℃0.16mm/m·℃0.012mm/m·℃

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
