Abstract
A compression member for a fluid transport pipeline provided with an inner protective liner, includes an annular ring intended to be forcibly inserted inside the pipeline. The pushing end of the ring comprises an annular flange protruding radially outwards and forming a bearing surface for a tool pushing the ring inside the pipeline, an annular cavity formed upstream of the flange, and an annular element for filling the cavity, intended to be inserted inside the cavity of the ring, the filling element being an independent part of the ring which has a frustoconical shape so as to facilitate the passage of scrapers inside the pipeline once the filling element is inserted inside the cavity of the ring.

A compression member for a fluid transport pipeline provided with an inner protective liner, comprising an annular ring intended to be forcibly inserted inside the pipeline and which comprises a downstream insertion end with a frustoconical shape, an upstream pushing end opposite to the insertion end, and a substantially cylindrical central portion connecting the upstream and downstream ends together and intended to compress one end of the inner protective liner against an inner wall of the pipeline,
- wherein the pushing end comprises:
- an annular flange protruding radially outwards and forming a bearing surface for a tool pushing the ring inside the pipeline;
- an annular cavity formed upstream of the flange;
- and
- an annular element for filling the cavity, intended to be inserted inside the cavity of the ring, the filling element being an independent part of the ring which has a frustoconical shape so as to facilitate the passage of scrapers inside the pipeline once the filling element is inserted inside the cavity of the ring.
