GEOSAN PE Double structured wall rigid conduit
- CLASS:SN4 | SN8
GEOSAN double structured wall pipes, corrugated outside and smooth inside, were developed by KOUVIDIS in 2012 and presented in the Greek market in 2013 as a safer and more economy solution than cement and PVC pipes. They are produced following the co- extrusion method from specially stabilized raw materials of high density polyethylene (HDPE) and are classified as SN4 and SN8 according to their ring stiffness. They are fully complied with the strict European Standard EN 13476-3 for Plastic piping systems for non-pressure underground drainage and sewerage made of unplasticized polyvinyl chloride (PVC-U), polypropylene (PP) and polyethylene (PE).
APPLICATION FIELD
They are intended for waste water collection in sewage networks as well as for the drainage of stormwater in road networks. They are also suitable for a multitude of free-flow sewage applications, such as in airports, tunnels, parking spaces, structural projects etc.

1SN 4 | SN 8 Ring Stiffness according to EN ISO 9969
2Ring flexibility RF30 according to EN ISO 13968
3The pipe is formed at its ends during the production process. The female end carries an elastomeric sealing ring at its inner wall while the male end comes with a smooth wall and a smaller outer diameter in order, when connecting each other to achieve a secure connection and the necessary water tightness
4GEOSAN 2nd generation pipes are manufactured from plastic materials of an exceptional molecular structure which achieve exceptional resistance to diluted acids (pH<2), alkaline solutions (pH>12) and mold according to ΕΝ ISO 10358
5The special sealing elastomeric rings, in combination with the geometry of the external wall of GEOSAN pipes, fulfill EN 1277 by ensuring permanent leak-tightness
6Exceptional impact strength according to EN 744
7They have excellent abrasion behavior thus preventing the depositing of dirty materials (fat, salts, etc.) in their smooth internal wall
8Exceptional resistance to solar radiation for at least 24 months, thanks to the aging stabilizers incorporated in the raw material of their outer wall
9Their much lower weight facilitates their loading, transport and storage
10Made from 100% ecofriendly materials that comply with the requirements of the European RoHS and REACH regulations, regarding the use of chemicals and hazardous substances, respectively, and can be recycled at the end of their product life cycle, without burdening the environment
11Their light yellow color RAL 1017 (saffron yellow) was selected for the inside of GEOSAN pipes in order to facilitate as much as possible the work of the sewage network cleaning and inspection crews
