Method of manufacturing pipes of externally calibrated plastic material, consisting essentially of passing the tube, at the exit of the extrusion machine, by a row on which the vacuum is practiced and equipped with cooling at the end of which said row presents its surface equipped with holes that put it in communication with a vacuum chamber, connected to a depressor installation, whose chamber is surrounded by another through which circulates an appropriate refrigerant fluid, so that the passage of the tube is fully adapted to the the inner diameter of the row and its exit from the same, already cold, externally presents this constant diameter in all its length.
