Research has established that operational damage of pipeline systems for oil product processing (PSOP) occurs due to turbulent flow of the main product, caused by structural features, which leads to cavitation in a localized area under conditions favorable for development of cavitation-erosion embrittlement and failure. Continuous monitoring of the wall thickness of critical areas of branch pipes and reducers, and restoration of them with high quality materials makes it possible to exclude critical situations and improve their corrosion resistance. 1. Turbulent flow of the overhead product, caused by structural features, leads to cavitation in a localized area under conditions favorable for development of cavitation-erosion and hydrogen embrittlement, and failure. PSOP metal composition and condition, i.e., an increase in silicon, sulfur, and hydrogen content, and also high banded pearlite grain size, typical for the condition of metal after rolling, presence of a considerable amount of sulfide inclusions, promote intensification-erosion, hydrogen embrittlement, and failure. 2. Continuous monitoring of wall thickness for PSOP reducers and branch pipes makes it possible to exclude dangerous situations during their operation. 3. Restoration of PSOP branch pipes and reducers made of high quality material has made it possible to increase their corrosion resistance to a considerable degree.
