Development status and improvement strategy of in-line inspection technology and management

Abstract

Pipeline defects have always been the dominant factor leading to pipeline failure. Using in-line inspectiontechnology to inspect and identify various pipeline defects has become a widely acknowledged practice in Chinaand abroad. In order to further promote the development of in-line inspection technology and the improvement ofmanagement level, the technology capability and development history of typical in-line inspection technology servicecompanies in China and abroad were systematically combed, the technical limitations of in-line inspection technologieswere analyzed for the inspection of girth weld defects, crack defects, pinhole corrosion defects and the stress state ofpipelines, and the existing problems in the management of in-line inspection technology were summarized from threeaspects of government supervision, pipeline enterprise management and in-line inspection technology service providers.The multi-dimensional strategy was proposed for solving the limitation of inline inspection technology and expectedto provide reference for the development of inline inspection technology and the improvement of management level infuture.
