PP Land drainage system
The sewer pipe system made of PP is produced in the diameter range DN/OD 110 - 800 mm and in the stiffness classes SN 2, SN 4, SN 8, SN 12, SN 16. Pipes for external drains are orange-brown (RAL) 8023), uniform in terms of shades and intensities with a smooth outer and inner surface. All types of sewer pipes and fittings are interconnected between each other and with smooth-walled pipes through sleeves with a groove in which an elastomeric seal is placed.
Polypropylene (PP) is a material with high resistance to chemical compounds. Piping systems made of PP in accordance with this standard are resistant to a wide range of pH 2 (acid) to pH 12 (alkali), corrosion caused by water such as municipal sewage, rainwater, surface water and groundwater. Information on the chemical resistance of PP materials can be found in ISO/TR 10358: 1993, for rubber materials in ISO/TR 7620: 2005. The PP sewerage system with gaskets is resistant to maximum permanent sewerage temperature above +90 C. Pipes and fittings are resistant to abrasion. In special cases the abrasion resistance can be tested according to the method specified in EN 295-3.
- Underground unpressurised drainage and sewerage in the ground in a road lane (under road or off-road) or other areas used for communication technology.
- Under harsh conditions, e.g. low temperatures, high groundwater level; exposed to tough operating conditions, e.g. high temperatures and chemical aggressiveness of wastewater, very shallow or deep foundations, high dynamic loads of the casing, increased abrasion resistance.
- In gravity drainage, rainwater and industrial drainage.
