Abstract: The construction of standard system by Chinese enterprises is characterized by the repeated and crossing contents, as well as multiple reference levels, of the single technical standards and the standards formulated by the standards committees of various disciplines. Thus, it is prone to causing the problems such as poor connection of standard content, great difference in requirements of implementation, and uneven development in the long-term application. In order to implement the National standardization development program and the strategic deployment of the PipeChina, the construction of PipeChina-featured integrated standard system for integrity management of oil and gas storage and transportation assets was practiced through combing the relevant laws and regulations, the national and the industry standards on integrity management of assets, with reference to the relevant Canadian national standards and the best practice results of the well-known foreign energy companies in the internal construction of integrated standards. Specifically, the integrated standard framework for integrity management of assets was built, and the preparation principles of integrated standards were established, including the unified object recognition, technical requirements and business management. The swim-lane flow chart for quality control of integrated standards was created. In addition, the integrated standards covering the integrity management of assets were formulated, including the general specifications for integrity management of assets, and the codes for integrity management of oil and gas pipelines. In this way, the problems of coordination, applicability and advancement of standards were effectively solved. In general, the research results could provide powerful guarantee for the realization of digital guidance of asset integrity management business objects and the operational activities.
