🔹 Installation
- Jointing Method: Heat fusion welding (polyfusion or socket fusion), ensuring leak-proof joints.
- Fittings: DADEX provides a full range of compatible fittings (elbows, tees, reducers, valves).
- Steps:
- Cut pipe to required length.
- Heat pipe and fitting using a fusion tool.
- Insert pipe into fitting and allow cooling.
- Pressure test system before commissioning.
- Advantages: No leakage, corrosion-free, lightweight, easy handling, and quick installation compared to metal pipes.
🔹 Usage
- Domestic: Hot and cold potable water supply in homes and apartments.
- Commercial: HVAC chilled/hot water distribution in offices, hospitals, and hotels.
- Industrial: Compressed air lines, chemical-resistant fluid transport.
- Public Infrastructure: Landscaping, sports facilities, and water distribution networks.
⚠️ Key Considerations & Risks
- Temperature Limit: Though resistant to high temperatures, prolonged exposure above 95°C may reduce lifespan.
- Pressure Testing: Always conduct hydrostatic testing after installation.
- Compatibility: Avoid transporting highly oxidizing chemicals unless specifically approved.
- Installation Quality: Poor welding or misalignment can cause leaks or reduced performance.
