Title:
PIPELINE DEFORMATION INTERNAL DETECTION METHOD AND DEVICE BASED ON MAGNETIZATION TECHNOLOGY
Document Type and Number:
WIPO Patent Application WO/2023/284499
Kind Code:
A1
Abstract:
A pipeline deformation internal detection method based on a magnetization technology, comprising: obtaining composite magnetic field information, a composite magnetic field being the vector sum of a magnetic field generated by a magnetic field generator and a magnetic field generated after the inner surface of a target pipeline is magnetized by the magnetic field generated by the magnetic field generator, and the magnetic field generator being located in the target pipeline (S101); determining a deformed area and an undeformed area in the target pipeline according to the composite magnetic field information (S102); and determining the deformation amount and the deformation inclination angle in the deformed area (S103). The detection does not involve a contact type detection probe, the phenomena of serious abrasion, scratching of the inner wall of a pipeline, and bouncing when a detection probe is far away from a defect area are avoided, and accuracy of a detection result of pipeline deformation is higher. Further provided is a pipeline deformation internal detection device based on the magnetization technology.
