Can PPR Pipe Fittings Be Used for Hot Water Systems?

1. Introduction: Key Requirements for Hot Water System Fittings

  • Global hot water system market grows at 7.3% annually
  • Requires fittings with high temperature resistance, corrosion resistance, and pressure tolerance
  • ifan Pipeline’s PPR fittings meet EU EN 12201 standards for 95℃ hot water systems

2. Core Performance Advantages

  • High Temperature Resistance:
    • Long-term operation: 70℃ (50-year lifespan)
    • Short-term peak: 95℃ (100-hour duration)
  • Pressure Rating:
    • Standard classes: 1.25MPa/1.6MPa/2.0MPa
    • Burst pressure: ≥5.0MPa (vs. industry standard 3.5MPa)
  • Corrosion Resistance:
    • Chloride-ion resistant (vs. copper pitting corrosion)
    • No electrochemical corrosion risks

3. Performance Comparison with Traditional Fittings

4. Technical Requirements for Hot Water Systems

  • Expansion Compensation: Install expansion joints every 5 meters
  • Water Quality: Compliant with GB/T 17219 drinking water standard
  • Pressure Testing: Conduct 1.5x working pressure test per EN 805

5. ifan Pipeline Solutions

  • Patented Technologies:
    • Copper-inset elbows
    • Pressure-balanced tee fittings
  • Custom Services:
    • Full DN20-DN110 sizes for hot water systems
    • Free thermal expansion calculation service
  • Quality Assurance:
    • NSF/ANSI 61 certified for drinking water
    • 100% pressure tested (0.8MPa for 2 hours)

6. Typical Applications

  • Residential central heating systems (villas/apartments)
  • Hotel centralized hot water systems (40 tons/day capacity)
  • Solar thermal projects (differential temperature systems)
  • Industrial cooling loops (≤95℃ operating conditions)

7. Case Studies & Test Data

  • Hangzhou Luxury Residential Project: Zero leaks in 5 years
  • Laboratory Results:
    • 95℃ cycling test: 5,000 hours no deformation
    • 500ppm chloride environment: 3,000 hours no corrosion
