天燃气管道的维护.doc

论文 摘 要 管道输送石油天然气，具有高效、低耗、连续输送和自动化程度高等优势，成为当前物流的重要形式之一和国民经济和社会发展不可缺少的“生命线”。但因其具有高能高压、易燃易爆、有毒有害、连续作业、链长面广、环境复杂等特点，决定了其安全管理的极其重要性。现在天然气管道的破坏严重的影响了天然气的正常的工作运输。 I 天燃气管道的维护 Abstract Pipeline transport oil and natural gas, with high efficiency, low consumption, continuous transmission and automation degree higher advantage, become the logistics one of the most important ways and national economic and social development of the indispensable quot;lifelinequot;. But because of its high energy high pressure, inflammable, explosive, toxic or harmful, continuous operation, chain long side wide, environment characteristics of complex, which determined the great importance of safety management. Now the destruction of natural gas pipeline serious impact on the normal work of the gas transport. This paper mainly analyzes in natural gas pipeline maintenance and repair of the daily aspects, first analysis of the natural gas pipeline will appear the common problems, some must abide by the rules. Again to natural gas pipeline anticorrosion methods, to the pipeline corrosion at home and abroad and the latest test method; In natural gas pipeline and the non-artificial appear artificial destroyed some of the detection methods, some common instrument equipment and processing method. Key words: natural gas pipeline; corrosion; Detection method; weld; equipment II 西南石油大学应用技术学院毕业论文 目 录 摘 要 ...............................................................
