Managing Corrosion in Soil

Methods to limit corrosion in soils include:

• Proper selection and design of materials.
• Metals should be coated where possible. Bituminous coal tar and asphalt dip coatings are effective for under ground piping. Imbedding pipes in concrete has also been used to limit corrosion.
• Cathodic protection should be used where possible.
• Pipes in the vicinity of electric railroad tracks or other similar equipment must be electrically insulated. One method is to coat the piping with hot asphalt followed by a concrete encasement. Organic dielectric coatings have also been developed for this purpose.
