Numerical simulation of galvanic corrosion of a tube-fitting steel assembly in a chloride environment

Galvanic corrosion is a complex and significant issue that affects metal structures across various industrial environments, especially in the presence of chloride solutions. In this study, we investigate the galvanic corrosion behavior of a steel tube assembly exposed to a chloride solution using advanced numerical simulation software. By leveraging multiphysics modeling techniques, we developed a comprehensive numerical model that integrates the electrochemical processes involved in galvanic corrosion. This model considers the electrochemical properties of the materials comprising the assembly and the environmental conditions, such as chloride solution concentration and conductivity.

Our study focuses on key parameters including corrosion rate, corrosion potential, and the distribution of damage within the assembly. The simulation results reveal critical insights into the mechanisms governing galvanic corrosion, offering a deeper understanding of how these factors contribute to the degradation of metal structures in chloride-rich environments. Additionally, our findings enable the prediction of the long-term behavior and performance of such assemblies under corrosive conditions.

This numerical approach presents a cost-effective and efficient alternative to traditional experimental methods, facilitating the evaluation and optimization of corrosion protection strategies. By reducing reliance on extensive physical testing, our model supports the design and implementation of more effective corrosion mitigation measures, ultimately extending the lifespan and reliability of metal structures in challenging environments.
