The rising cases of corrosion problems in pipelines, refineries, water treatment and petrochemical plants, as well as in power generation plants in recent time have been attributed to industrialization. The longevity and dependability of essential assets must be ensured through effective corrosion management. The various techniques applied for corrosion protection are discussed in this review. But in recent years, the development of response surface methods (RSM) and artificial neural networks (ANN) has shown exciting prospects to transform the corrosion monitoring process. This review paper gives a thorough overview of corrosion optimisation strategies. The role of ANN and RSM in predicting corrosion using various parameters is discussed. By providing insights into the current state of research on ANN, this paper aims to promote a deeper understanding. The review emphasises how crucial it is to adequately manage corrosion if essential assets are to last a long time and function consistently.

During the water pressure test of the waste heat boiler of the heavy metal recovery unit, many leaks were found in the superheater tube bundle. These leaks were all concentrated at the simmering bend location of the superheater tube parent material. This prompted an investigation into the causes of cracks in the superheater tubes of the waste heat boiler. The study followed a systematic approach, starting with macroscopic examination of the samples, nondestructive radiography, water quality examination, chemical composition analysis, metallographic analysis, scanning electron microscopy analysis, and energy dispersive spectroscopy (EDS). The results of these analyses revealed that the cracks were expanding from the inner wall to the outer wall, the cracks were dendritic in distribution, and the inner and tip of the cracks were full of grey-white oxides, with typical stress corrosion cracking characteristics. The water quality detected a pH value of 10.7, which was alkaline. This sequence of events ultimately led to the conclusion that the tubes were subjected to alkaline stress corrosion cracking due to the concentration of stresses at the simmering bends, which led to the leakage.
