<p>A pipe section provided with at least one spigot end with the same internal diameter as the pipe section for renovating a part of a pipeline without branches, said pipe section being provided in an undetachable manner at the transition to the spigot end (8a, 8b) with a stiffening ring (4a, 4b) having a larger external diameter than the external diameter of the pipe section. The spigot end (8a, 8b) is provided with a groove (5a, 5b) for the accommodation of sealing elements which can interact with the inside of a plug socket (7). Spigot ends (8a, 8b) of two adjacent pipe sections (2a, 3b) are accommodated in a plug socket (7), the length of plug socket (7) being greater than the distance between the supporting faces (11, 11b) of the spigot ends (8a, 8b) of two adjacent pipe sections. The pipe section is preferably made of fibre-reinforced thermoplastic material. <IMAGE></p> |
