KML Resistance

Chemical resistance

PREIS® KML is the perfect solution for building drainage whenever the composition of wastewater requires specific materials.

As resistance of the pipe system against wastewater is not only influenced by the composition of chemical elements, but also by pressure, temperature, etc., details given in the table have to be taken as a recommendation for your orientation. For detailed information, please, ask for our form “Resistance”. Send us your detailed specifications or a sample - we will be pleased to analyze it in our laboratory.


For oleiferous wastewater and effluents containing benzine we recommend our PREIS® Rapid couplings with NBR lining as an alternative. If the PREIS® KML piping system is underground-laid or it is exposed to various weather conditions, we recommend the PREIS® Rapid INOX coupling made of stainless steel.
