| Summary: | This review concentrates on corrosion properties that expose to soil
environment. Forms of corrosion classified with respect to outward appearance
and altered physical properties are uniform attack, galvanic corrosion, erosion
corrosion, stress corrosion, crevice corrosion, pitting and inter-granular
corrosion. A porous soil may retain moisture for a longer period for optimum
aeration and indirectly increase the initial corrosion rate. External corrosion is
corrosion attack upon the outside of the pipe soil medium and the most failure
mechanisms experienced by buried steel pipelines. Many systems possibly in
contact with soil have risk to be corroded such as storage tanks and pipelines. |
