根据理论分析和实验验证,提出三种新的检测理地管道直流干扰腐蚀指标,并建立埋地管道直流干扰腐蚀的评价体系.
Current standards in petroleun industry prescribe two ispecting indexes for estimation of DC in-terference corrosion of buried pipelines, namely:excursion of pipe/soil potential and magnitude of poten-tial gradient in surface. These indexes are not well defined and lack of quantitative relationship with inter-ference corrosion, so that the standards are difficult to perform in practices. In present paper, three new in-specting indexes for DC interference corrosion are proposed and the corresponding estimating systems are discussed and created.
