HISTORICAL DOCUMENT. This NACE International standard practice establishes the general principles to be adopted to minimize the effects of stray current corrosion caused by direct current (DC) and/or alternating current (AC) from external sources on steel reinforced concrete (RC) and prestressed concrete (PC) structures or structural elements. The standard practice offers guidance for the design of concrete structures that may be subject to stray-current corrosion; the detection of stray current interference; the selection of protection measures; and the selection of mitigation methods.
Time-tested and proven methods to control corrosion of oil and gas industry infrastructures (pipelines, facilities, and refineries) include the use of appropriate materials, protective coatings, cathodic protection (CP), and corrosion inhibitors.
Criteria for evaluation, qualification, and selection of materials, coatings and application of CP arequantitative and are typically followed rigorously (Table 1). Standards on these quantitative criteria are established, and in many cases have been adopted by regulatory authorities.
