Zusammenfassung:A joint for coaxially rotating pipes comprising a seal packing (5), placed in the annular clearance between the surfaces (8, 9) of embracing (1) and embraced (2) pipes, a device (6) for tightening the seal packing (5) provided with clamping rings (16, 17) enclosing the seal packing and a thrust ring (7) bearing an axial force created by the pressure of the medium transported through the pipes (1, 2), that thrust ring being mounted at the end (4) of the embraced pipe (2). The thrust ring (7) is so mounted that it is allowed to move axially, relative to the pipe, in the annular clearance or gap, with the result that the thrust ring exerts a pressure on the clamping ring (16) placed against the seal packing at the side of the end (4) of the embraced pipe (2) and adapted for the axial displacement thereof relative to the pipe, in the annular gap.
