Research and Calculation of Corrosion Cracking of Steels under the Action of Tensile Stresses in an Aggressive Environment

Stress corrosion cracking (SCC) is a global problem for steel structures; about 80% of all Russian pipelines are subject to this type of corrosion. There is an urgent need to introduce systems for the diagnosis and monitoring of corrosion cracking. For the qualitative performance of these procedures, studies are needed to determine the time required for the introduction of a corrosion inhibitor and its amount to maintain a protective concentration. The first section presents an analysis and review of the literature on the problem of corrosion: factors affecting the cracking process, methods for protecting steel against corrosion, and a review of modern systems for monitoring and diagnosing corrosion. The second section presents data from an experiment to determine the dependence of the time to metal destruction on the inhibitor concentration.
