Best plastics for pipes
PVC-U and PVC-C dominate cold-water and DWV; PEX and PPR own domestic hot water; HDPE (PE100) owns gas and water mains; PVDF and PP-natural cover industrial chemical lines. The right choice depends on pressure class, temperature and fluid.
What to look for
- Long-term hydrostatic strength (MRS) rated for the pressure class
- Temperature rating covering the full duty cycle
- Chemical compatibility with the transported fluid
- Jointing method (solvent weld, electrofusion, push-fit) available on site
