Abstract

Flexible thermoplastic piping for conducting a fluid, comprising an inner layer of octene-1 in contact with said fluid and an outer layer of pvc, the inner layer being joined to the outer layer by a layer of adhesive. Procedure for simultaneously fabricating four pipes for conducting a fluid, comprising: (a) connecting four extruders, to extrude octene-1, to extrude an adhesive, to extrude rigid pvc and to extrude flexible pvc to an extrusion head and (b) ) simultaneously extruding on four fixed-pitch calibrators (6) an octene-1 profile to form an inner layer, an adhesive profile to form an intermediate layer of adhesive, a rigid pvc profile and a flexible pvc profile to form a pvc outer layer, where said pvc outer layer comprises a spiral of rigid pvc co-extruded with flexible pvc.
