Areas of application

Our KML pipes are suitable for aggressive wastewater in the field of kitchens and hospitals or industrial facilities such as laundries or laboratories. 


Hot, greasy and aggressive wastewater in these areas requires the inner coating to offer increased resistance. The special requirements became the decisive factor for the development of the KML system by RSP®. In cooperation with paint manufacturers, coating materials have been developed precisely for this extreme area of application. Excellent casting quality and the resulting smooth surface finish enable excellent bonding of the coating materials with the pipes and fittings.
