Analiza korozijskih procesa čeličnih cijevi u agresivnom mediju

During the exploitation period pipelines are often in contact with aggressive media that could cause corrosion. Rigid and gas product that occurs as chemical reactions of the steel and media could decrease cohesive forces in crystal net, induce mechanical features of pipes and shorten of exploitation lifetime. Such weakened material structure is subservient to rapid corrosion processes that can multiple decreased exploitation lifetime of pipeline. To find interaction between aggressive environment and microstructure the flow and corrosion speed in exploitation have been studied. Corrosion persistence and observed changes on the material are exam by visual optical method, measuring of wall thickness of pipe, and through analysis of material structure changes with optical microscope. The article can serve for situation analysis, decision making and looking for measures and their implementation.
