Practice and cogitation on pipeline integrity management

With the development of domestic pipeline industry, a lot of research has been done on pipeline integrity technology and management. Based on the practice of pipeline integrity management, the paper analyzes the present challenges facing the safe running of pipeline, including different cognition ability, low safety management behavior, pipeline construction and running capacity limited by imperfect standards or codes, pipeline development outpacing technical reserve, and deficiency of professional technical service level and strength. The practice and gains in integrity technology and management are listed, such as the key factors of pipeline cracking accidents, best practices of pipeline detection and evaluation, and the reform of management and decision-making mode. The paper envisions the development of this technical area in the future, puts forward prospective problems, such as how to face the big change from big data, how to recognize the characteristics of the safety management of pipelines, and how to understand the core of pipeline integrity management under construction, and points out the direction of future development of pipeline integrity management.
