1) thermoplastic piping systems for non pressure waste water discharge (intermittent flow up to 95 °C) inside buildings;
2) thermoplastic piping systems for non-pressure underground drainage and sewerage (continuous flow up to 45 °C and intermittent flow up to 95 °C);
3) thermoplastic rainwater piping systems.
