SUMMARY:

The analysis of localized corrosion in experimental laboratory tests represents a complex challenge, especially when trying to understand the propagation of defects in carbon steel pipes in the oil and gas industry. Among the various methodologies available in the literature, for both dynamic and static tests, the focus is on finding test devices and types of specimens that can closely simulate real field conditions. In this context, approaches involving the fabrication of artificial defects are important, because they allow an analysis of the conditions that influence the formation and propagation of pitting in metallic materials. This study evaluated localized corrosion in API X65 steel with artificial defects of different geometries in an autoclave rotary cage system. The material will be evaluated under dynamic conditions of rotation, time, CO2 pressure, temperature and salinity. The different geometries and dimensions of the artificial defects resulted in variations in the morphology and adhesion of the iron carbonate films, directly affecting the corrosion rate of the steel.
