Process for the manufacture of rigid pipes calibrated on a basis of plastic material, characterized in particuly by that the material in the soft state, as presented at the exit of the annull nozzle of the continuous extrusion machine, is subjected to a peripheral vessel or depression, which has to expand radially and apply it against one or several cylindrical calibration surfaces arranged concentrically in relation to the tube, and because said peripheral action is combined with a cooling of the tube on the outside and with a longitudinal traction made in the portion of the tube already hardened that follows the calibration zone.
