🛠 Installation Guidelines
- Preparation: Clean and chamfer pipe ends before welding.
- Fusion Welding: Use a calibrated socket fusion machine at 260–280°C.
- Cooling Time: ~10–12 minutes for 75mm fittings.
- Pressure Testing: Test system at 1.5× operating pressure after installation.
- Storage: Keep fittings in shaded, dry areas to avoid UV damage.
🌍 Usage Applications
- Hot & Cold Water: Domestic plumbing, potable water supply.
- HVAC Systems: Chilled water, heating loops, radiant floor heating.
- Industrial Use: Chemical-resistant pipelines, compressed air (with derating).
- Commercial Buildings: Hospitals, hotels, offices, and large-scale water distribution.
⚠️ Risks & Considerations
- Pressure Derating: At high temperatures (95°C), PN 25 reduces to ~4–5 bar.
- UV Sensitivity: Though UV-stabilized, prolonged direct sunlight exposure can weaken material.
- Installation Errors: Over-insertion during welding may cause bead formation and flow restriction.
- Compatibility: Must match pipe diameter and PN rating to avoid leaks or failures.
