污水管道腐蚀机理及防护措施

摘要

The corrosion mechanism of oil field sewage pipelines was analyzed. Types, conditions and characteristics of internal and external corrosion of pipelines were investigated. The main factors to cause the corrosion of sewage pipeline were listed;the impact of these factors was analyzed. According to the domestic and foreign research results on pipeline corrosion and research situation, some protection measures were proposed, such as using the coatings, electrochemical protection, using nonmetal pipelines, adding corrosion inhibitors and so on.%　　分析了油田污水管道腐蚀机理，分别考察了管道外腐蚀和内腐蚀的类型、条件及特点。列举了造成污水管道腐蚀的主要影响因素，具体分析了这些因素的影响情况。根据国内外对管道腐蚀的研究结果及研究状况，提出了采用涂层、电化学保护、应用非金属管道及添加缓蚀剂等预防措施。
