These are produced with high-density polyethylene with characteristics that conform to the EN 12666 standard where the application field concerns pipeline systems for non-pressure drainage and sewerage outside the building (application code “U”) and inside and outside the building (application code “UD”);
they are completely black;
they are characterised by maximum simplicity and reliability in joining and laying operations thanks to the characteristic properties of polyethylene including: lightness, flexibility and resistance to corrosion;
they adapt to any possible adjustments in the laying plan;
they have a high capacity to self-clean even at low gradients and speeds;
they ensure elevated chemical inertness guaranteed by the constancy of the hydraulic performance.
