THE ECOPAL ADVANTAGES
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.
Ecopal 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.
Ecopal is produced in 6 and 12 meter bars; in this way the number of joints is reduced.
Ecopal 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.
Ecopal 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.
Ecopal 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.
Ecopal is partially flexible and can avoid obstacle during pipe-lining and digging inaccuracy.
