摘要
目前,石油、天然气资源的输送主要依靠长距离埋地管道来实现,管材一般为普通钢制螺旋焊管。由于长输天然气管道一般采用浅埋地方式铺设,特别是在气候湿润,地下水位较高和河流众多,埋地穿越地段地形复杂,土壤对管道有着不同程度且很强的腐蚀性,漏损处也不易及时发现,且地下管道的维修要进行大量的土方工程,比新建管线还要费工,因此,如何防止输气埋地管道的腐蚀破坏至关重要。
At present,petroleum and natural gas resources transmission rely mainly on the long distance buried pipeline to realize,pipe general for ordinary steel spiral welded pipe.Because long natural gas pipeline general use shallow buried way laid,especially in the humid climate,underground water level and higher many rivers,buried through the complex terrain of location,soil of the pipes to the different and very strong corrosive,leakage place not easy also discovered in time,and the maintenance of the underground pipes to a lot of earthwork,more truouble than build new pipeline,therefore,how to prevent gas buried pipelines of corrosion damage is very important.
