Vitrified clay pipes for sewerage projects: robust, watertight and immediately available
Deschacht offers an extensive range of gutter pipes and fittings for street drainage, available in DN125 to DN800. Thanks to the inner and outer enamel coating, the pipes are completely watertight, wear-resistant and exceptionally resistant to chemical attack. Lengths of up to 2.5 m ensure quick, efficient installation with fewer connections on site.
Why choose stoneware?
Vitrified clay pipes combine high wear resistance, excellent chemical resistance, and maximum impermeability thanks to their glazed finish. It is a robust and dimensionally stable material with a very long service life, ideal for heavily loaded sewerage infrastructure such as street sewers, renovation, and industrial applications.
