The science of pipe corrosion: A review of the literature on the corrosion of ferrous metals in soils

The paper reviews the literature that may assist in forming a multiscale model of corrosion in soils. This model should take into account macro-environmental processes (rainfall, etc.), soils processes (water movement, oxygen transport, etc.), processes within the oxides, and the electrochemical activity occurring at the metal surface. The literature reviewed includes traditional corrosion research such as surveys and historical analysis of buried pipelines, scientific exposures of buried metal, results from buried sensors, and laboratory studies aimed to duplicate soil exposures. Also included are wider studies on water and solute movement in soils, and oxygen transport through soils.
