Abstract: To solve the technical problems in the on-line inspection of buried pipeline crossing the hazardous chemicals tank area, through the tests of lead breaking, artificial excitation and on-line monitoring of a buried pipeline of crude oil transportation under the conditions of excavation and normal use, the propagation characteristics of acoustic emission signals in pipelines and the detection reliability are analyzed including the influencing factors of pipeline geometry, propagation distance, amplitude attenuation and energy drop. The feasibility of on-line detection of buried pipeline corrosion is fully studied, therefore, it provides a reliable technical supporting method for the integrity management of pipelines in hazardous chemicals tank area.
