Engineering approach to corrosion management

Abstract

Comprehensive engineering approach to corrosion management is a rational and cost-effective way to combat corrosion in industrial plants, and also to predict the remnant life of the components. The paper discusses how such an approach helps in the understanding of corrosion processes and their mechanisms which, in turn, aids in the selection of appropriate materials and fabrication processes, good design, management of residual stresses and environment and, thereby, helps in the control of corrosion. The importance of corrosion monitoring using NDE techniques in industries to assess the corrosion damage and the remnant life of the component has been described. The paper deals with the importance of accurate predictive models for remnant life estimation based on quantitative fitness-for-service assessment methodologies, and utility of laboratory experimental simulation techniques for solving the corrosion problems.
