Abstract
Method, for manufacturing a composite pipe (CP) with a tubular wall, this wall comprising at least one extruded tubular part (1), referred to as the first tubular part (1), this first tubular part (1) being made up of a first polymeric material (100), this method being characterized in that the step of extruding the first tubular part (1) of a first polymeric material (100) involves the use of a first polymeric material (100) of the type capable of being cross-linked by infrared radiation, and this step of extruding the first tubular part (1) of said material is immediately followed by a step of irradiating the extruded first tubular part (1) with infrared radiation in order to accomplish said cross-linking reaction.
