A system includes a Christmas tree (XT) having at least one valve, the XT being coupled to a wellbore. The system also includes a pressure boundary tool adapted to provide a secondary boundary for the XT. The pressure boundary tool includes a plug body to be positioned against a valve member of the at least one valve; a seal to be energized into a valve body of the at least one valve; and a plate arranged proximate the seal, the plate being moveable between a first position and a second position, the first position energizing the seal and a second position deenergizing the seal. The pressure boundary tool is positioned within the XT on a side of the valve member closer to the wellbore.

System and method for a secondary pressure boundary tool

An outer wellhead member has a bore with a first profile portion and an annular recess. A tubular inner wellhead member with a centralizer/overpull ring is lowered into the outer wellhead member. The centralizer/overpull ring is biased to expand outward to engage the bore of the outer wellhead member to center the inner wellhead member within the bore as the inner wellhead member is lowered through the bore. The recess of the outer wellhead member is adapted to receive the centralizer/overpull ring and oppose axial movement of the centralizer/overpull ring to enable an upward test pull of the inner wellhead member.
