Transport of soft or aggressive water
PUR pipelines have a polyurethane internal protective lining that is better suited to very soft and/or aggressive water than the traditional cement mortar coating. The range of application of cement coatings is specified in Annex E of standard EN 545.
PUR pipes are also suitable for the transport of raw water or water with a chemical analysis that does not vary between the pipeline’s entrance and exit points, such as water for bottling.
In order to offer comprehensive solutions, PUR pipelines can be combined with other ranges according to their diameters:
- Bead position c165to170
- Bead position c90to135
- Bead position c150to165
- Bead position c165to195
- Bead position c180to243
Internal coatings for the safe transport of soft water
Soft or aggressive waters contain few ions and are not saline; they originate from sources such as rivers, lakes, rainwater, and glaciers. Soft waters are often contaminated by human activities such as chemical waste from industry or agricultural by-products. We make sure to provide a safe transport of ductile iron pipes thanks to our specialized PAM internal coating solutions.
