What is PPR socket?

1. Definition and Structure of PPR Sockets

  • A socket joint is the core connecting component in PPR piping systems
  • Consists of a female (recessed) end and male (protruding) end, joined via heat fusion welding
  • ifan Pipeline’s sockets use German imported raw materials, compliant with ISO 9001 standards

2. Key Advantages of PPR Sockets

  • Leak-proof Design: Fusion creates monolithic structure, eliminating leakage risks of threaded joints
  • Temperature Resistance: Handles -20℃ to 95℃ long-term temperature variations
  • Corrosion Resistance: Chemically inert material suitable for acidic/alkaline fluids
  • Easy Installation: Requires no specialized tools, installable by single operator

4. Installation Process

  1. Cut pipe and clean ends
  2. Heat socket and pipe ends (260℃±5℃) with professional welder
  3. Insert quickly and hold for 10-15 seconds
  4. Pressure test after cooling (0.6MPa for 1 hour recommended)

5. Common Applications

  • Residential plumbing systems (hot/cold water supply)
  • Solar water heater connections
  • Industrial circulating water systems
  • Underfloor heating manifolds

6. ifan Pipeline Solutions

  • Full range of socket sizes (DN20-DN110)
  • Custom sizes available (e.g., DN75×32 reducers)
  • Free welding training videos and technical manuals

7. FAQs

Q: Can PPR sockets weld with other materials?
A: Only compatible with PPR. Use transition fittings for metal/PEX connections

Q: How to fix failed welds?
A: Cut off defective section and re-weld with new socket

Q: What’s the service life?
A: Over 50 years under normal conditions
