REHAU SPECIAL PVC
Drainage casings made of PVC-U are suitable for drainage purposes in transport and underground construction for the collection (accumulation), conveyance and drainage of water infiltrating from rock massifs. The goal of drainage using drainage casings is to improve the mechanical characteristics of the surrounding soil by reducing the amount of water content. The piping is suitable for horizontal, vertical and inclined installations.
Applications
- Drainage and drainage wells in transport and underground construction.
- Geotechnical exploration and monitoring wells.
Chemical resistance
PVC-U pipes are resistant to all substances normally found in soil and water from pH 2 (acidic) to pH 12 (alkaline). In the case of extraordinary chemical and temperature loads, we recommend consulting our technical department.
Quality requirements
PVC-U drainage casings are manufactured per STN EN 1401-1 and DIN 4262-1 requirements. These pipes are regularly inspected in the in-house laboratory to meet internal product range requirements.
Product range
- Non-perforated (solid) pipes in diameters DN/OD 90 to 200 mm.
- Perforated pipes (slit filters) from DN/OD 90 to 200 mm.
- Pipes are offered in a standard length of 4 m, pipes are connected with a threaded socket connection or with a threaded socket-less connection (pipes can also be produced in other lengths in the range of 1-5 m upon request).
