A report prepared for the Concawe Working Group on Oil Pipelines covers the causes of internal corrosion of pipelines (chiefly the presence of water in the case of oil products); methods for combating internal corrosion, including settling out of water from liquids, the addition of corrosion inhibitors, and the application of internal protective coatings; the external corrosion of buried or immersed steel pipelines as a result of electrochemical phenomena or the activities of sulfate-reducing bacteria; protective coatings for buried pipelines, including hot-applied continuous asphalt or coal-tar coatings, plastic tape would around the pipeline, plastic continuous coatings applied by extrusion, painting, or spraying, thick asphalt mastic coatings, and concrete coatings (which are used over the hot-applied bituminous or coal tar coatings); cathodic protection methods, including the sacrificial anode and the impressed direct-current method; studies necessary before installing a cathodic protection device; and pipeline safety codes, which require that buried pipelines by adequately protected against corrosion.
