| Specifications
for the contract |
|
|
High density polyethylene co-extruded twin-wall pipe, plain and white internally and corrugated and black externally for underground sewer ducts not under pressure manufactured in compliance with the prEN 13476-1 type B standard, certified by the P IIP/a mark
and by UNI 10968/1 type B rule certified by UNI/IIP mark issued by the Istituto Italiano dei Plastici (Italian Institute for Plastic Materials)
stiffness class corresponding to SN 4 (or 8) kN/m2, produced in 6 or 12 meter
bars with jointing by means of a PEAD coupling, P IIP/a and UNI/IIP mark and EPDM lip seal.
Pipe must be produced by ISO 9001:2000 and ISO 14001:2004 certified companies
(environmental certification).

The calculation has been made by the GAUCKLER – STRICKER method.
The roughness parameter suggested by ASTM for standard ducts with manholes, adapters, bends and gully pots: Ks = 80.
The suggested velocities are:
- 0.5 to 4 m/s for black waters
- 0.5 to 7 m/s for rainwater.
