To save energy and increase the cycle times, a process for bending small-calibre pipe sections (1) of thermoplastic, in particular for fuel lines, brake lines or hydraulic lines, in which the plastic pipe section (1) is bent by a bending tool, with heating, and is cooled again to stabilise the bending, can be carried out by introducing a straight core (3) of metal alloy having a memory effect into the straight pipe section (1), then heating the metal alloy having the memory effect so that the pipe section is bent and, after cooling, withdrawing the core from the pipe section (1). <IMAGE>
