EVORAIN
Storm water pipe, EN 13476-3 type B
SN8 [kN/m²], DN/OD 160, 200, 250, 315, 400 mm
EVORAIN double-wall pipes with profiled (corrugated) external and smooth internal surface, type B, polypropylene (PP) pipes for the construction of stormwater infrastructure. Their respective flow rate of stormwater and reliability guarantees excellent work application in pipeline network systems.
- DN/OD 160, 200, 250, 315 and 400 [mm]
- Produced according to EN 13476-3
- Ring stiffness: SN8 [kN/m²]
- Standard pipe length: 6 [m]
The design of the pipe consists of two layers with a structured outer and smooth inner layer surface from PP material. The external side is corrugated and the profile properties guarantee high mechanical strength and impact resistance parameters. Smooth internal walls of the pipes ensure the excellent hydraulic properties required for pressure-free (natural gravity) systems.
EVORAIN pipes are flexible and preserve water tightness even in the most problematic soil conditions. They are resistant to deformation when installed under roads with heavy loads.

At one end EVORAIN pipe is equipped with welded-on solid PP coupling, but at the other end - a rubber sealing ring² is installed (placed) on the first full groove of the corrugation. The supplied sealing ring grants a hermetic seal with a pressure rating of ≥0,5 [bar] for the coupling area.
¹ Other lengths are available on request
² The sealing ring is resistant to oil according to the requirements of EN 681-2 p.5.10. Compliance is determined by the "Volume change in oil" test according to ISO 1817.
