Polyethylene manhole MOULDED BASE

recessed

Main advantages: . Lightness for easy transport, storage and installation at the yard . Watertightness is guaranteed by the seal installed between the base and the rise and the seals between the base and the pipes . Quick delivery . Easy assembly at the yard . Installation of a sewer pipe system made of the same material . Possibility to connect pipes made of different materials (plain PEAD, PVC, Grès). Technical characteristics Five types of moulded bases are available: one for manholes of diameter ID.400 mm, one for manholes of diameter ID.600 mm, one for manholes of diameter OD.630/800 mm and two for manholes of diameter OD.1000/1200 mm. The bases allow the insertion of pipes from OD.110 mm to OD.630 mm. The special cone-shape structure makes easier the rise introduction and assures a perfect hydraulic tightness after the pipe has been jointed or welded. Moreover the Ecopal manhole allows to lay the base according to the duct position. Couplings are made by cutting the wall of the inlet area with a special tool and by inserting the relative special seal. This seal designed just for Ecopal guarantees a perfect tightness even by misaligned piping and avoids also the pipe displacement.
