The aim of this work was an in-depth investigation of corrosion mechanisms affecting industrial plants and infrastructure, with a particular focus on oil pipeline tubes, aluminum profiles used in construction, and cooling systems in thermal power plants. The purpose was to understand how corrosion impacts the safety, efficiency, and longevity of these key industrial components and how accredited tests are conducted for the evaluation and prevention of corrosive processes with accent on quality management within every step. The theoretical and methodological foundation of the work is based on the application of various tests; from optical emission spectrometry and EDS microanalysis to SEM analysis and hardness testing, which allow for a detailed analysis and assessment of the chemical composition, microstructure, and mechanical properties of materials. The research results have pointed to complex corrosion mechanisms, such as localized corrosion, pitting, and transgranular corrosion, and specific deposits containing elements like copper, zinc, oxygen, and sulfur have been identified, indicating potential corrosive agents. Based on these findings, strategies for reducing corrosion have been proposed, including the application of iron sulfate and biocides and changes in processing and storage processes. This work contributes to a better understanding of corrosive processes in industrial applications and provides reliable data that enable industrial entities to make informed decisions related to materials, design, and maintenance, highlighting the importance of accredited testing in ensuring quality and compliance with standards.
