Installation Guidelines
Best practices for optimal performance and longevity
Do's
- ✓Ensure butt-fusion welding is performed using correct temperatures for the specific PE grade.
- ✓Verify the SDR and PN ratings match the intended application's hydrostatic design stress.
- ✓Use pipes with sufficient carbon black content for long-term outdoor UV exposure.
- ✓Follow the MRS guidelines to ensure the pipe meets its 50-year design life at 20°C.
Don'ts
- ✗Do not use non-potable pipes for drinking water distribution.
- ✗Avoid exceeding the maximum allowable hydrostatic design stress specified for the material.
- ✗Do not install pipes that have deep scratches or physical damage exceeding standard tolerances.
- ✗Avoid using materials that do not conform to the required design coefficient 'C' for pressure safety.
