SPEED•PIPE® GROUND FOR DIRECT BURYING speed•pipe® ground are suitable for direct burying in all FTTx-sections as well as for branches off existing duct routes. The dimensionally stable wall thickness out of first-class PE-HD protects every single duct against the emerging soil pressure. Due to the higher vertex pressure in comparison for example to a PE-HD duct Ø 50, the ducts keep their round cross-section. Also after decades the inside slide ribs contribute to the establishment of an optimum air cushion for high distances during the blowing-in process of fibre-optic cables. • for branches off existing duct routes or for house connections in direct burying • dimensionally stable due to the higher wall thickness: high vertex pressure for a consistently round cross-section and high distances when blowing-in fibre-optic cables • specified slide ribs for each dimension, for an optimum air cushion of the fibre-optic cable during the blowing-in process • available in various dimensions and in strong colours for better distinction • combination with pipe-in-pipe solutions by means of appropriate fittings (see page 32) Characteristics
