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

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

Are PVC Pipes Environmentally Friendly?

When I first reviewed the lifecycle assessment data for various piping materials, I was surprised by PVC’s complex environmental profile. While working on a municipal water project, we had to carefully balance durability requirements with environmental concerns, leading me to research PVC’s true sustainability picture thoroughly. PVC pipes present a mixed environmental picture: they’re durable,

What Makes PVC Pipes Easy to Install?

Having installed thousands of feet of piping across residential and commercial projects, I consistently find myself reaching for PVC when ease of installation matters most. Recently, I supervised a team that installed an entire commercial drainage system using PVC in half the time estimated for metal piping. PVC pipes install easily because they combine lightweight

Can PVC Handle High-Temperature Water Flow?

I once responded to an emergency call where PVC pipes in a residential hot water system had softened and burst, causing extensive water damage. The homeowner had used standard PVC instead of temperature-rated materials, unaware of the significant limitations. This experience taught me that understanding temperature boundaries is crucial for plumbing safety. No, standard PVC
