Dissertation note: Thesis (M.Sc.) - Cairo University - Faculty of Engineering - Department of Metallurgical Engineering Summary: The purpose of this research is to identify the effect of various parameters (concentration, temperature and stirring speed of sodium sulfates) in testing electrolytes on corrosion behavior of ASTM A106 Gr.B carbon steel pipelines.The morphology and composition of the corrosion product deposits were determined using optical and scanning electron microscopy while EDAX analysis was used to determine the chemical composition of the corrosion products. Based on weight loss as well as potentiodynamic polarization measurements, the highest corrosion rate was detected for electrolytes containing 0.5 M Na2SO4.Temperature influence was significant on oxide layer density and stability, with the appearance of thick cracked layer as the temperature as well as the sulfate concentration increased. Increasing solution speed had a corrosive effect on metal surface as the highest corrosion rate was observed for the highest speed (1250 rpm)
