%X Current standards in petroleun industry prescribe two ispecting indexes for estimation of DC interference corrosion of buried pipelines,namely:excursion of pipe/soil potential and magnitude of potential gradient in-surface.These indexes are not well defined and lack of quantitative relationship with interference corrosion,so that the standards are difficult to perform in practices.In present paper,three new inspecting indexes for DC interference corrosion are proposed and the corresponding estimating systems are discussed and created.
