Aggressive wastewater by default may be defined through its components and their composition as well as through the fluctuating temperature. Moreover, the trend to save water in building drainage leads to an increased concentration of organic and inorganic substances in drainage pipes.
The coating applied inside and outside causes PREIS® KML to be ideal for these special requirements. The inside coating of PREIS® KML consists of a double fully cross-linked epoxy resin coating, each of them being 120μ thick. The exterior of the pipes is provided with a zinc coating of 130 g/m2 and an epoxy resin cover coating of at least 60μ thickness.
