Process for the extrusion of thermoplastic tubes, characterized in that it consists of extruding a tube of thermoplastic material through a nozzle of annular section, maintaining an overpressure with respect to the atmospheric pressure inside the extruded tube and limited the diameter of the latter , while being prevented from dilation with a first portion of a cooling fluid that is at its boiling point then with a second portion of said cooling fluid that is at a temperature lower than that of the tube, so that the latter is solidifies in contact with this second portion of refrigerant fluid.
