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

3. Comparison of Socket Types

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
