PVC drainage pipes are manufactured from rigid PVC (PVC-U) without the addition of plasticizers, using suitable stabilizers. As a result, they have high impact strength and can maintain their physical structure for a long time. These drainage pipes are produced in diameters of 50, 80, 100, 125, 160, 200 mm and are made with holes for drainage purposes, and without holes for discharge purposes. They are standardly produced in lengths ranging from 50 to 200 meters and can be manufactured in different lengths upon request. They are used in all structures requiring drainage and/or discharge.
