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

Type	Application Scenarios	Advantages	Precautions
Straight	Linear pipe connections	Low cost, high versatility	Control insertion depth
Elbow	90° directional changes	Built-in flow design reduces resistance	Avoid forced bending
Tee	Branch line connections	One-piece structure stronger	Pressure distribution
Reducer	Transition between sizes	Gradual design minimizes turbulence	Match pressure ratings

4. Installation Process

Cut pipe and clean ends
Heat socket and pipe ends (260℃±5℃) with professional welder
Insert quickly and hold for 10-15 seconds
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

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
