Abstract: A magnetic retrieval tool for retrieving devices, such as probes, from a pressurized system. The retrieval tool uses a magnetic coupling to transfer movement of an external mechanism (i.e. external to the pressurized system), such as by an operator's manual movement, a motor or other drive, to an internal mechanism (i.e. internal to the pressurized system). The magnetic coupling may be through a wall of a pressure vessel using an outer magnetic core coupled to the outside of the pressure vessel which magnetically couples to an inner magnetic core disposed on the inside of the pressure vessel, such that translational or rotational movement of the outer magnetic core cause substantially simultaneous and corresponding translational and/or rotational movement of the inner magnetic core. An end effector tool is coupled to the inner magnetic core to engage and retrieve or insert the device into the pressurized system.

Abstract: A method of sensing corrosion of a pipe covered by a layer of insulation comprises positioning a CUI sensor radially adjacent an outer surface of the pipe. The CUI sensor comprises a non-conductive base having a first end and a second end opposite the first end. In addition, the CUI sensor comprises a first test circuit mounted to the base. The first test circuit includes a first conductor, a second conductor, and a first testing element extending between the first conductor and the second conductor. Further, the method comprises exposing the first testing element to the same environment as the outer surface of the pipe. Still further, the method comprises determining whether the first testing element has corroded through. Moreover, the method comprises assessing whether corrosion of the pipe has occurred based on the determination of whether the first testing element has corroded through.
