PE MANHOLES FORMED BY SPIRAL TYPE OF PIPES

Inspection manhole for water with gravity flow, made with corrugated pipes in HDPE, DN spiral …. mm (rated internal diameter), obtained by the continuous winding of a rectangular cross-section profile on a spindle with circular inside cavities for ensuring and improving the moment of inertia and therefore the resistance to static and dynamic loads. Dimensions and mechanical properties shall be in accordance with DIN 16961 Part 1 and 2, ring stiffness class …. (or the European standard EN 13476-1 for structured pipes in PE type A2; the crush resistance of the tube, determined in accordance with EN ISO 9969, must correspond to SN ….)

FEATURES AND APPLICATIONS

– high versatility design;
– structured profiles (externally smooth or profiled) sized according to technical needs
– suitable for installation with aquifer level
– very high resistance to point loads
– possibility of union between the unit elements with tongue and groove electro fusion
– diameter range from DN-ID 1000 to DN-ID 2500 mm
