Telescopic PP pipe dn 315x800mm, with hooks, for cast iron manhole cover 315, black color (Diamir 315) 2781331081

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. non-manhole inspection chambers—allowing access to the storm or sanitary sewage system using inspection or cleaning equipment, 2. manhole inspection chambers—allowing personnel access to the storm or sanitary sewage system, 3. manholes with a silt trap—used in storm sewage (stormwater inlets) and drainage; when "blind" inlets are used, the manholes are utilized, for example, as tanks or sewage pumping stations.
