FIELD: mechanical engineering.
SUBSTANCE: pipe joint comprises a pipe component with a flange having a toroidal surface (F1) on an end side, and also with a ring enclosing the pipe component, a sliding cuff with an internal diametre matching to an external diametre of the flange and with one end having a hole for pipe component reception. The flange is movable in the sliding cuff, and with an outer socket sleeve fixed on the sliding cuff and located around the pipe component, and a ring with an internal diametre matching to an external diametre of the ring with an internal cavity through at least one hole in the pipe component connected to an internal portion of the pipeline and with the ring forming a toroidal surface (F2) being under pressure which is basically equal to the toroidal surface (F1).
EFFECT: invention provides higher reliability of pipe joint.
