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

What Makes PPH Ideal for Wastewater Systems?

During a chemical plant wastewater system upgrade, I recommended PPH pipes where stainless steel had failed in just two years. Five years later, the PPH system shows no signs of deterioration, demonstrating how this material excels in aggressive wastewater environments where metals often fail prematurely. PPH (polypropylene homopolymer) excels in wastewater applications due to its

Does PPH Maintain Stability in High Temperatures?

While working on a chemical processing plant’s hot effluent system, I specified PPH piping that has now operated continuously at 85°C for over eight years without failure. This real-world performance demonstrates PPH’s exceptional thermal stability when properly selected and installed. Yes, PPH (polypropylene homopolymer) maintains excellent stability at high temperatures, with continuous service ratings of

How Durable Are PPH Fittings in Harsh Environments?

I recently inspected a chemical processing plant where PPH fittings had served flawlessly for 15 years in acid exposure that destroyed metal components within months. This real-world validation demonstrated why PPH has become the preferred choice for aggressive industrial applications. PPH (Polypropylene Homopolymer) fittings demonstrate exceptional durability in harsh environments due to their superior chemical
