Enhance your corrosion prevention strategies with detailed predictive simulation and modeling What is crevice corrosion? Crevice corrosion occurs in confined spaces where stagnant solutions create a corrosive environment. This phenomenon occurs when metals, especially CRA's, are exposed to high chloride environments, like seawater. The protective oxide layer breaks down in these confined spaces, leading to aggressive localized corrosion. Over time, crevice corrosion leads to significant damage, equipment failure, costly repairs and safety hazards. The real-world problems caused by crevice corrosion Crevice corrosion is a significant risk to the longevity and safety of industrial equipment. Accurately predicting and preventing crevice corrosion is critical to maintaining operational efficiency and avoiding unexpected failures. Corrosion in subsea oil and gas equipment Subsea pipelines and wellheads that are made from duplex stainless steels are particularly vulnerable to crevice corrosion. The continuous exposure to chloride-rich seawater under low oxygen conditions leads to localized breakdown of the protective layer. Predicting the pH and chloride concentration within these crevices is essential for mitigating this risk. Issues in reactors and storage tanks in chemical processing Chemical plants process aggressive mixtures that exacerbate crevice corrosion, particularly in reactors and storage tanks. The chemical environments, including the dissolved metals concentration (e.g., Cr and Mo), can lead to significant localized corrosion. Predicting the corrosivity of these environments is crucial for preventing leaks and maintaining safety. Reduced lifespan of heat exchangers in power generation and cooling systems
