Ecopal 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.

peculiar geometric structure guarantees a high deflection resistance and it is produced in two ring stiffness classes (Class 4 kN/m2 - Class 8 kN/m2). In this way the pipe can fulfil different applications even in deep underground.

Ecopal outer black wall guarantees a high UV stability, inner wall is white to ease the pipe TV inspection.

is produced in 6 and 12 meter bars; in this way the number of joints is reduced.

can be connected with coupler and elastomeric seal or butt welding. The elastomeric seal is placed inside the corrugation, thus avoiding the risk of being displaced during the coupling operation.
The elastomeric seal of a particular profile not only avoids leakage, but also the groundwater entrance into the pipe.

is extremely versatile, due to the possibility to have a wide assortment of special fittings and can be connected with any other type of existing pipes.

is extremely easy to handle due to its lightness.
It is easy to store, to transport and to install and does not need any particular equipment to be moved.

is partially flexible and can avoid obstacle during pipe-lining and digging inaccuracy.
