ABSTRACT OF THE DISCLOSURE The wall of the pipe section comprises a plurality of superimposed layers, which are formed from plastic and inorganic materials. The layer of inorganic materials forms the central layer, whose wall portions are in each case connected by a connecting layer to a reinforcing layer. Whilst the central layer ensures the dimensional rigidity of the pipe section, the two reinforcing layers, which are made from a fibre-reinforced plastic, ensure the strength of the pipe. This combination of different layers is an inexpensive solution, which only requires that amount of expensive plastic as is required for the strength of the pipe. Through applying a plastic protective layer to the outer circumference of the pipe and a protective layer to the inner circumference of the pipe, the durability of the pipe section is ensured.
