摘要
新技术、新材料日渐广泛的应用必然会使天然气管道系统面临一系列新的可靠性问题。在此形势下,采用天然气管道可靠性设计方法可以有效保障天然气管道的可靠性。本文介绍了天然气管道可靠性设计方法的发展历程、基本概念及设计流程,重点阐述了4种计算可靠度的方法:一次二阶矩法、蒙特卡洛法、故障树分析法和贝叶斯网络法,并分析了4种方法的优缺点与适用条件。
The increasing application of new technologies and materials will inevitably make the natural gas pipeline system face a series of new reliability problems.In this situation,the reliability design method of natural gas pipeline can effectively guarantee the reliability of natural gas pipeline.This paper introduced the development course,basic concept and design process of reliability design method for natural gas pipeline,and focuses on four methods for reliability calculation:first-order second-moment method,Monte Carlo method,fault tree analysis method and Bayesian network method,and analyzed the advantages,disadvantages and applicable conditions of the four methods.
