PE pipeline with structured wall profile of spiralled type for non pressure sewer systems, available in large diameters up to Ø 2.500 mm. The pipeline is characterized by an high versatility, with various types of wall profile that can be combined on almost every diameter, and by high tightness thanks to the innovative electro-fusion socket.
HIGH DENSITY POLYETHYLENE (HDPE) PIPELINES WITH STRUCTURED WALL PROFILE – SPIRALLED TYPE – FOR UNDERGROUND NON PRESSURE SEWER SYSTEMS
Supply and laying of High Density Polyethylene (HDPE) pipelines for underground non pressure sewer systems, with structured wall profile of spiralled type in conformity with DN 16961, extruded by producer certified UNI EN ISO 9001:2000. The internal wall profile shall be smooth and light coloured so as to allow a better visual or camera inspection, the external wall structure shall guarantee the necessary moment of inertia in order to obtain the intended ring stiffness. The pipe shall report the marking indicated by the reference standard on the external surface; the joining system shall be executed through a special polyethylene socket, manufactured through continuous coiling on a mandrel without break in continuity with the pipe and provided with special internal resistance for electro-fusion with the successive male element.
The ring stiffness would be equal to SN______*(____KN/m2), measured in accordance to standard EN ISO 9969. The ring flexibility shall be verified according to standard EN 1446 with deformation equal to 30% of the external diameter of the pipe (RF30 to be brought in marking). The abrasion resistance of the material must be verified according to EN295-3.
The minimum tensile strength value on the jointing seam between the spirals will be superior to 1020 N when verified according to method EN 1979
HDPE SGK spiral pipe can be used for different applications:
