EVODRAIN FLEX- high-density polyethylene (HDPE) double-wall (R2 type) drainage pipe with profiled (corrugated) external and smooth internal surface according to product standard DIN 4262-1.

  • Nominal ring stiffness SN4 or SN8 [kN/m²]
  • Factory-installed textile filter
  • Water permeability ≥ 50 [cm²/m]
  • (TP) type perforation: 360° totally perforated pipe with water inlet perforation openings evenly distributed around its ring
  • Advantages

    Excellent impact resistance properties

    Higher resistance against UV radiation

    Chemical and biological inertness

    Environmentally neutral material: PE is 100% recyclable and can be used repeatedly

    Excellent long-term strength properties (service life up to 50 years)

  • Recommended application

    For drainage on plots where the depth of groundwater deposition is less than the drainage norm, i.e. land plots for which, due to high groundwater levels, the topsoil is unable to drain excess moisture in the spring period, as well as due to high groundwater levels, underground engineering structures, roads, etc. are damaged.

    Drainage system EVODRAIN FLEX R2 type pipes are applicable for installations in:

    In agriculture, forestry, in parks, squares and peat fields
    Temporary and permanent drainage at construction sites
    Stadiums and sport complexes
    Pavements, pedestrian and bicycle paths
    Landfills (liquid and biogas collection)
    Road construction - with and without traffic load
  • Technical information

    The color of the inner surface of the pipe is black (RAL 9004) and the outer surface is blue.

    • Produced according to DIN 4262-1
    • Material: high-density polyethylene (HDPE)
    • Ring stiffness SN4 / SN8 [kN/m²]
    • Type A woven textile filter material  - polyester (PET)
    • Type A woven textile filter material arel density 105 - 135 [g/m²]
    • Resistance to external blows H50 > 1.2 [m] (according to EN ISO 11173)

    Every EVODRAIN FLEX pipe coil is equipped with a double sleeve, which provides easy connection of pipes.
    It is possible to achieve a hermetic seal with a pressure rating of ≥0,5 bar (for the coupling area) by adding a rubber sealing ring. Oil-resistant¹ sealing rings are available on order, compliant with the requirements of EN 681-2 p.5.10.

     
    ¹ Compliance is determined by the "Volume change in oil" test according to ISO 1817.
