Abstract: A stress detecting system and method operable to detect stresses in a conduit or pipe includes a tool movable along a conduit or pipe and operable to generate a magnetic field. The tool is operable to sense magnetic Barkhausen noise within the conduit, such as within a wall of the conduit, in response to the tool generating the magnetic field. The stress detecting system is operable to detect a change in stress along the conduit responsive to an output of the tool. The system may detect changes in stress that are caused by geological changes or shifting or thermal changes at or near the conduit to determine changes in stress along the conduit and changes in stress along the conduit over time and during use of the conduit.
