Abstract: The present invention relates to a process for producing pipelines with heat-storing properties, in which a) organic polyisocyanate is mixed with b) at least one polymeric compound having at least two isocyanate-reactive hydrogen atoms, c) optionally chain extender and/or crosslinker, d) catalyst, e) wax and f) optionally other assistants and/or additives, to give a first reaction mixture, and the first reaction mixture is applied to a pipe and allowed to react fully to give a first polyurethane layer. The present invention further relates to a pipeline with heat-storing properties obtainable by such a process.
