Infrastructures

A complete range with two PVC piping systems, signed by FERSIL, for drainage and non-pressure sewerage networks (with gravity flow), buried outside (Series U) and/or under the building structure (Series UD):

• PVC-U solid wall pipes according to EN 1401, with a ring stifness ≥ 2 kN/m2 (SN2) or ≥ 4 kN/m2 (SN4) and PVC-U fittings according to EN 1401 with SDR 51 (for SN2 and SN4 pipes ) or SDR 41 (for SN4 and SN8 pipes);
• 3KKK PVC-U structured wall Type A – foamed, according to EN 13476-2 with a ring stiffness ≥ 2 kN/m2 (SN2), or ≥ 4 kN/m2 (SN4), or ≥ 4 kN/m2 (SN8 ). This range, which is heavily deployed on the market, meets the requirements of existing regulations for drainage and sewerage piping systems in public networks. Also responds to the ecological concerns of the circular economy, as the technology used in FERSIL 3KKK pipes allows them for the absorption of adequate levels of recycled material without losing pipe’s mechanical strength, functionality and durability.
