External PVC drainage pipe 110x3.2x3000 SN4 Class N ML (multilayer, foamed) 3069331

Durable wastewater drainage with PVC-U pipes

External drainage pipe made of polyvinyl chloride (PVC-U) is a reliable solution for building wastewater drainage systems in outdoor conditions. It is characterized by high resistance to corrosion and mechanical damage, which guarantees long-term operation. Made of PVC-U with a wall thickness of 3.2 mm and a diameter of 110 mm, it ensures efficient flow and minimizes the risk of clogging.

The pipe has a circumferential stiffness class of SN4, which means it is adapted to the loads occurring in typical outdoor installations. The structure with a foamed core improves insulation properties and reduces thermal expansion – the coefficient of expansion is 0.07 mm/(m.K), and the thermal conductivity is 0.15 W/(m.K). The orange color of the pipe makes it easier to identify in the ground.

Application and structural features

These pipes are ideal for building storm and sanitary sewers in green areas, under sidewalks or roads. They meet the requirements of PN-EN 13476-2 standard (classes S and N) and have a technical approval from ITB class L, which confirms their high quality and safety of use. Wall roughness at the level of 0.02 mm promotes free flow of the medium. The pipe length is 3 meters, and the outer diameter of the socket is 126 mm – this should be taken into account when planning connections. The lack of a socket requires the use of appropriate fittings to connect to other elements of the sewage system.
