干线管道的可靠性是一种由若干单项属性组成的综合属性,它包括无故障性、可维修性、耐久性、工况可控性、生命力和安全性。干线管道运行的可靠性在很大程度上取决于外部条件:一方面是自然环境的作用;另一方面是油气开采系统和油气处理系统的工作能力,还包括满足用户向运输企业提出的要求。在设计干线管道时,要对情况进行综合分析,即不仅要研究管道本身,而且要研究工艺相关项目对管道的影响。干线管道通过能力、动力设备可靠性指标和维护参数等是实际设计工作中可靠性指标的预测信息,量化到具体设计工作,就要考虑油(气)站分析、输送设备规格型号和输送设备连接方式的具体特点,必要时可对各站的设备可靠性指标进行具体化和精确化。根据俄罗斯现行采用的可靠性设计指标,分别对管道通过能力等一系列参数进行了计算。
The reliability of a trunk pipeline is a comprehensive property consisting of a number of individual properties, including no-fault, maintainability, durability, work condition controllability, vitality and safety. The reliability of the operation of the main pipeline depends to a great extent on external conditions: on the one hand, the role of the natural environment; on the other hand, on the capabilities of oil and gas extraction systems and on oil and gas processing systems, and on the requirements of users for transport enterprises. In the design of trunk pipelines, we must conduct a comprehensive analysis of the situation, that not only to study the pipe itself, but also to study the impact of process-related projects on the pipeline. The capacity of the main pipeline, the reliability index of power equipment and maintenance parameters are the forecasting information of the reliability index in the actual design work. When quantifying to the specific design work, it is necessary to consider the analysis of oil and gas stations, the specifications and models of conveying equipment and the connection of conveying equipment The specific characteristics of the mode, if necessary, each station equipment reliability index for the specific and accurate. According to the current reliability design indicators used in Russia, respectively, a series of parameters such as pipeline passing capacity were calculated.
