Abstract

Procedure for the manufacture of a gas-tight joint by external boring; between a thick-walled tube of material with coefficient of thermal expansion α2 and a thick-walled counterpart of material with coefficient of thermal expansion α1 other than coefficient α2, characterized in that: a tube with a terminal section of reduced wall thickness is used and a counterpart with an internal cylinder of a length that is at least equal to the length of that of the terminal section of the tube of reduced wall thickness and whose internal diameter has an axial course that corresponds to that of the external diameter of the terminal section of tube. of reduced wall thickness and the part immediately adjacent to it, and also a material seat ring with a coefficient of thermal expansion essentially equal to that α1 of the counterpart, 1-corresponding to the axial length of the seat ring at least to the axial length of the terminal section of the tube, the outer diameter of the tube presenting an axial course corresponding to here that of the internal diameter of the terminal section of the tube of reduced wall thickness, the seat ring being inserted in the tube's terminal section and both parts joined with the counterpart and then boring both the seat ring and the tube in the counterpart.
