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
