Studies made by Battelle Memorial Institute's Columbus Laboratories verify that no single factor is responsible for stress-corrosion cracking in burial pipelines. A number of conditions must exist for cracking to occur: The steel must be exposed to certain types of chemical environments (principally carbonate-bicarbonate solutions), the electrode potential must be within a narrow range, and the stress must be sufficiently high. The occurrence and rate of cracking also are strongly influenced by temperature, stress fluctuations, the condition of the coating, and the condition of the steel. An extensive research program is presently underway to determine the best ways to prevent stress-corrosion-cracking failures in existing and future pipelines.
