According to UNI EN 13476-3, corrugated pipes for sewerage networks<\/a> produced by Polieco have a profile falling under type B, i.e. a ‘pipe with a smooth inner surface and a solid or hollow spiral or annular rib’.<\/p>\n

The production of Polieco’s corrugated pipes stems from the study of a special equipment developed in Germany for structured walls. This technology required the pipe profile to have a semi-circular top, which was specially designed to optimise load resistance.<\/p>\n

The wave shape of the upper part of the rib, which is typical of diameters from DN\/OD 250 mm, gives the possibility to change the ring stiffness from SN 4 to SN 8 kN\/m2<\/sup> by acting on rib thickness. For diameters lower than DN\/OD 250 mm, the section\u2019s characteristics are slightly different as the spacing of the rib is too short for such a complex structure and the wall thickness cannot be decreased too much.<\/p>\n

The reference standard is silent on the colours of<\/strong> corrugated<\/strong> pipes, but special colours were chosen for the two types of pipes manufactured by Polieco.<\/p>\n

The ECOPAL pipe<\/a> is black on the outside for better resistance to UV radiation and grey on the inside.<\/p>\n

ECOPAL 2.0<\/a> is a co-extruded, double-wall pipe, smooth on the inside in white to facilitate video inspection of the pipe and corrugated on the outside in blue, and includes a white, longitudinal line to facilitate pipe alignment.<\/p>\n
