A process for the manufacture of tubes, profile bars or similar hollow bodies, preferably of thermoplastic synthetic materials, characterized in that inside hollow bodies, preferably manufactured by the continuous extrusion process, static reinforcement elements are arranged, and by the preformed material, which leaves the nozzle in a still plastic state, is removed more quickly than that which leaves the nozzle, resulting in a stretch; because the still plastic material then travels a vacuum passage nozzle, which broadens the material radially, thereby stretching both the reinforcing elements, as well as the envelope, while then solidifying it to measure by cooling under vacuum ; and because the material is finally conducted through a hollow chamber, in which it is subjected to alpha and/or beta and/or gamma radiation.
