摘要: 为了从定量分析的角度对在役管道进行评价,基于超声LCR波油气管道在线应力检测装置开发了油气管道在线应力状态无损测量技术,并围绕地质灾害变形管段建立了“应力初测评价-维抢修措施建议-应力复测评价-管道定期检测”的工程现场管道维抢修评价方法,并对该方法进行了现场工程试用。结果表明,该方法是评价地质灾害变形管段在线应力状态的有效手段,为变形管段安全裕度和修复质量的定量评价提供了依据,为变形管段的后期维护提供了技术支持。Abstract: In order to evaluate the in-service pipelines from the point of view of quantitative analysis, this paper establishes a set of non-destructive measurement technology of on-line stress state in oil and gas pipelines based on ultrasonic LCR wave on-line stress testing device. And the engineering site pipeline maintenance evaluation method of “stress initial measurement and evaluation-emergency repair measures and suggestion-stress retest evaluation-pipeline periodic inspection” for the deformation section caused by geological disaster is built. In this paper, a preliminary field engineering trial of the method has been carried out. The results show that this method is an effective method to evaluate the on-line stress state of the deformed pipe sections caused by geological disasters, which provides a basis for the quantitative evaluation of the safety margin and repair quality of the deformed pipe sections, as well as technical support for the later maintenance of the deformed pipe sections.
