EVODRAIN HARD HDPE 180°
Locally perforated (LP), DIN 4262-1
SN8 (kN/m²), DN/OD 63, 75, 90, 110, 125, 160 mm
EVODRAIN HARD are rigid drainage pipes made of high-density polyethylene (HDPE) material. Double-wall (R2 type) according to product standard DIN 4262-1- with corrugated (profiled) external wall and smooth internal surface.
- Nominal ring stiffness class SN8 [kN/m²]
- Water permeability ≥ 50 [cm2/m]
- Standard pipe bar length: 6 [m]
- (LP) type perforation: 180° locally perforated pipe
LP type 180° partially perforated pipe with perforation opening on pipe surface located symmetrically to the vertical axis of the pipe at 180° ±10° area, but the lower part of the pipe ''flow channel'' is unperforated. It's used for liquid collection and transportation.

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
Field drainage
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 HARD SN8 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
EVODRAIN HARD HDPE pipe is equipped with a double sleeve. The color of the outer surface of the pipe is black (RAL 9004) and the color of the inner surface is white.
- Produced according to DIN 4262-1
- Material: high-density polyethylene (HDPE)
- Ring stiffness SN8 [kN/m²]
- Resistance to external blows H50 > 1.2 [m] (according to EN ISO 11173)
- Available sizes DN/OD 63, 75, 90, 110, 125, 160 [mm]
- Standard pipe bar length: 6 [m]
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.
