摘要 在天然气集输过程中,一些伴生气体的存在,往往会对集气管道有腐蚀作用,严重者会造成集气管道的破裂、破坏正常平稳供气、影响用户的生产和生活。本文分析了管道内腐蚀的类型可以分为均匀腐蚀、坑蚀等,并说明各种腐蚀类型产生的条件,着重分析了二氧化碳和硫化氢的腐蚀机理,指出了工程实际中常用的防腐措施如加缓蚀剂抑制腐蚀、利用涂层保护隔离管道与腐蚀介质、选用具有良好耐蚀性能的合金钢、采用清管作用清除管内水、污物和沉积物、防止管线堵塞、减小垢下腐蚀穿孔等,并对缓蚀剂的运用条件等进行分析,从而说明了研究天然气管道腐蚀的重要性和必要性。 In natural gas gathering and transportation process, a number of associated gas will have a corrosive effects for the pipelines, it will cause pipeline rupture, disruption of normal smooth gas supply and impact the user's production and living. In this paper, it analysis of the type of corrosion, Corrosion mechanism, anti--corrosion measures, corrosion inhibitors, points out the importance and necessity for the Corrosion Research.
