摘要
油气长输管道作为一种特殊设备被广泛应用于石油、石化、化工等各个行业。随着运行时间的增长,部分管道在设计、制造、安装及运行管理中的问题逐渐会暴露出来,致使管道事故时有发生,对人民生命财产安全、社会稳定和工业生产构成了威胁。如何发现管道缺陷,提高检测技术水平,确保压力管道安全可靠运行,变过去的不足维护和过剩维护为视情维护,是目前世界各国同行普遍关注和迫切需要解决的重大课题。文章介绍了当今国内外较为成熟、先进的管道外检测(涂层检测)和管道内检测(智能检测)技术和方法,并结合近年来在油气长输管道开展检测工作取得的一些经验,探讨了国内油气长输管道检测技术的发展情况以及薄弱环节,提出了相应的对策和措施。
As a special facility,long oil/gas transmission pipelines are widely used in the industries of petroleum, petrochemicals, chemicals, etc. As the operating time goes by,the defects of some pipelines on design, manufacture, in-stallation,and operation appear gradually. The pipeline accidents happen from time to time, which threaten the human lives and property safety, the social stability, and the industrial configuration. It is the major problem the colleagues all around the world commonly pay attention to, and need to solve urgently how to find the pipeline defects, improve the detection level, guarantee the safe and reliable operation of the pressure pipelines, change the situation from the insufficient or surplus maintenance in the past to the proper maintenance by situation. The article introduces the resent mature and advanced techniques of external pipe detecting (coating detection) and internal pipe detecting (intelligent detection) at home and abroad. With the experience obtained on the detection of oil/gas transmission pipelines at the resent years, the progress and weak links of the detection techniques of oil/gas transmission pipelines in China are discussed. And the corresponding countermeasures are proposed.
