The purpose of corrosion inspection in the petrochemical industry

Thread Content

Corrosion inspection refers to the use of various instruments, tools, and analysis methods to determine the corrosion rate of materials in process media environments. It provides engineering technicians with information on equipment corrosion in a timely manner, enabling them to take effective measures to slow down corrosion and prevent corrosion-related accidents. Corrosion inspection during major plant overhauls involves formulating a corrosion inspection plan tailored to the specific conditions of the plant. During the shutdown for overhauls, a specialized team is assembled to carry out inspections of the equipment and pipelines using macroscopic examination as well as other effective testing methods, in order to assess the morphology and condition of corrosion. Based on these findings, the mechanisms behind corrosion are analyzed, the corrosion rate is calculated, and the extent of damage is determined.
