PP telescopic pipe dn 315x375mm, with lugs, for cast iron manhole 315, black color (Diamir 315) 2781331041

Diamir sewage manholes are designed for the construction of gravity sewage networks (sanitary, storm, combined, industrial) and drainage. The product range includes three types of manholes: 1. inspection chambers (without covers/manholes)—allowing access to the storm or sanitary sewage system using inspection or cleaning equipment, 2. access inspection manholes—allowing personnel access to the storm or sanitary sewage system, 3. catch basins—used in storm sewage (stormwater inlets) and drainage; in the case of using "blind" inlets, manholes are used, for example, as tanks or sewage pumping stations.
