Abstract
A wear sleeve for use with a rotating control device (RCD) includes a wear insert and a retainer flange. The wear insert is formed in a tube shape with an outer profile to match an inner profile of a downstream neck of the RCD to be inserted into the downstream neck. The retainer flange extending from an outer surface of the wear insert to couple with a neck flange at an end of the downstream neck of the RCD.
Claims18
A wear sleeve for use with a rotating control device (RCD), the wear sleeve comprising:
- a wear insert formed in a tube shape with an outer profile to match an inner profile of a downstream neck of the RCD to be inserted into the downstream neck;
- a retainer flange extending from an outer surface of the wear insert to couple with a neck flange at an end of the downstream neck of the RCD;
- and
- wherein the retainer flange includes at least two through holes for connecting a tool to rotate the wear sleeve.
A wear sleeve for use with a rotating control device (RCD), the wear sleeve comprising:
- a wear insert formed in a tube shape with an outer profile to match an inner profile of a downstream neck of the RCD to be inserted into the downstream neck;
- and
- a retainer flange extending from an outer surface of the wear insert to couple with a neck flange at an end of the downstream neck of the RCD;
- and
- wherein the wear insert includes at least one of:
- an upstream portion having at least one upstream seal recess to accommodate at least one upstream ring seal between an exterior of the wear insert and an interior of the downstream neck of the RCD;
- or
- a downstream portion adjacent to the retainer flange having at least one downstream seal recess to accommodate at least one downstream ring seal between the exterior of the wear insert and the interior of the downstream neck.
A wear sleeve for use with a rotating control device (RCD), the wear sleeve comprising:
- a wear insert formed in a tube shape with an outer profile to match an inner profile of a downstream neck of the RCD to be inserted into the downstream neck;
- an insert protrusion that extends outwards from an outer circumference of the wear insert to match with a neck recess on the downstream neck of the RCD to limit movement of the wear insert in the downstream neck;
- and
- a plurality of grub screws to lock the wear insert within the downstream neck of the RCD;
- and
- wherein the wear insert includes a plurality of notches around an end of the wear insert.
