  • Segment isolation of internal pipe wall
    Patent number: 11118715
    Abstract: A method for isolating and performing work on a segment of a pipe includes delivering an isolation tool to a target location. A first seal member is actuated to form an annular seal around an outer surface of the isolation tool. A second ring body is moved away from a first ring body, elongating an isolation sheet that extends between the first ring body and the second ring body. The isolation sheet defines an annular work space between the outer diameter of the isolation sheet and the inner diameter of the pipe. A second seal member is actuated to form an annular seal around the outer surface of the isolation tool. A pressure within the annular work space is reduced by removing fluids within the annular work space with an ejector device. Work is performed within the annular work space with a tool assembly.
