No pressure underground sewer systems |

| For no pressure underground sewer systems Polieco produce Ecopal, an high density polyethylene co-extruded twin-wall pipe, corrugated externally and plain internally, and is an advanced product which offers technical and economical advantages. These kind of pipes for no pressure underground sewer systems is made with high density polyethylene, that is, a polymer which offers a high impact resistance even at low temperatures as well as an excellent chemical resistance, presents better resistance to the abrasion in respect to other materials used in pipe production. Hydraulic tests on Polieco pipes produced for no pressure underground sewer systems, show these pressure underground sewer systems pipes don't have any leaks in 15 minutes either under pressure (at 0.05 and 0.5 bar) or negative pressure (- 0,3 bar) conditions with deflection of the pipe and jointing coupler diameter and pipe misalignment, thanks to the use of the elastomeric seal. |
