<p>Dilation compensation device for pipes comprising an external tubular body and an internal tubular body coupled together telescopically, the internal body being able to move longitudinally and in rotation with respect to the external body and both having, at the free ends thereof, means for connection to respective pipes of an installation, the device comprising elastic seals positioned between the two bodies that render them leaktight. The two tubular bodies form a single piece and the inner section of the external tubular body has an intermediate segment of diameter D1, greater than the diameter of the contiguous segment, for coupling with the internal tubular body, constituting a portion of pipe in which the end portion of the internal body can move longitudinally, the mouth of the latter being expanded after it is inserted in the external body so as to form a stop that limits the movement of the internal body and therefore the extent to which it can be extracted from the external body.</p> |
