Auxiliary Effects of Corrosion Cells

Chapter 7 has provided many examples of corrosion cells that may happen in a soil environment. The following sections illustrate some effects these corrosion cells may have on buried structures with a particular focus on pipelines which are, by far, the greater portion of 

Soils containing organic carbon, e.g., muddy or swampy soils peat, fen, mud, marsh, and organic carbon 5% -12 

Severely polluted soil pollution by fuel ash, slag coal, coke, refuse, rubbish or waste water -12 

Resistivity variation between adjacent domains (all positive R2 values are treated as equal)  

Adjacent soils with same resistivity Embedded in soils with same structure or in sand 0
