High density polyethylene pipes (HDPE)

DMW smooth black surfaced polyethylene pipes conform to UNI EN 12201 and are non-toxic in accordance with national directives issued by the Ministry of Health.

Polyethylene pipes are distinct in the following respects:

  • increased resistance to corrosion and chemical agents;
  • greater shock resistance;
  • improved mechanical characteristics over time;
  • simple connectors;
  • greater crack propagation resistance (pipe resistance);
  • greater Notch Test resistance (pipe resistance) cut according to internal pressure requirements.


DMW drainage pipes can have different slot distribution. In particular DMW offers:

  • slots at 90° - 270° on casing;
  • slots at 180° - 180° on casing;
  • slots at 240° - 120° on casing;
  • 360° evenly distributed slots.

More or less slots can be distributed along the circumference according to the diameter of the pipe required. Pipes can be provided covered in geotextiles.
