Abstract: The present invention relates to a process for producing polyurethane-coated conduit elements, in which (a) aliphatic polyisocyanate is mixed with (b) compounds having at least two hydrogen atoms which are reactive toward isocyanate, (c) catalyst and (d) optionally other auxiliaries and/or additives, to form a first reaction mixture, the reaction mixture is applied directly or indirectly to a pipe and allowed to react to form a polyurethane layer, wherein the compounds having at least two hydrogen atoms which are reactive toward isocyanate comprise a compound based on an alkoxylation product of an aromatic starter molecule. The present invention further relates to conduit elements which can be obtained by such a process.
