摘要： The in-line device for determining mechanical stresses in pipelines is designed to move within the pipeline. The device features a cylindrical body that houses at least two coaxially positioned non-ferromagnetic disks. These disks are rigidly connected and arranged at a distance L. The device also includes at least four probes with 3D gradiometer sensors capable of scanning the inner pipe surface using the magnetic gradient tomography (MTM-G) method. The probes are rigidly fixed and coaxially positioned within the cylindrical body on the aforementioned disks, enabling scanning in three mutually perpendicular planes within the pipe space.

摘要： The invention relates to the field of measurement technology using computational technology and can be used in the industrial field that deals with pipelines (e.g., in the oil and gas industry, the construction industry, the energy industry, the nuclear industry, the utilities industry, the diagnostics of metallic structures, and the environmental protection industry). The technical result is an increase in the accuracy of determining mechanical stresses, while simultaneously providing the proper accuracy of detecting an anomaly source in a pipeline.
