Abstract: Based on summary and analysis of relative risk assessment method of pipeline system and asset integrity management(AIM) methodology, the paper points out that AIM methodology is a technical fundament to carry out integrity management of pipeline facilities. By means of analysis on the connotation and characteristics of integrity management of pipeline facilities, technology route to develop integrity management of pipeline facilities and assumption to establish its basic system framework are proposed, in which the core conception is first based on integrated AIM system to implement a further integrity management mode under precondition of taking process unit and vital component of equipment as a target risk management base, then build up system and platform closer to operation and management process and finally establish integrity management system of pipeline facilities in line with the conception and methodology of pipeline integrity management.
