Abstract
Process and plant for the production of thermoplastic resin pipes, particularly for drainage systems, which can be made of high and low density polyethylene, polypropylene, polyvinylchloride, polystyrene (including expanded polystyrene), polyurethane (including expanded polyurethane), and heterogeneous mixtures of recovered materials, in which a continuous hollow section 1, 2, 3a, 3b, 4a, 4b is extruded from a first extruder 5, subsequently wholly or partly filled with polyurethane foam or thermoplastic resin, in particular materials deriving from recycling or recovery, to be wound in a spiral on a shaping mandrel 8, the finished pipe being delivered to a stacking station 17 after being cut into lengths. <IMAGE>
