This work presents the electrochemical kinetics results measured during the corrosion of API X52 pipeline steel immersed in aqueous environments, containing dissolved hydrogen sulfide (H2S) under turbulent flow conditions. In order to control the turbulent flow conditions, a Rotating Cylinder Electrode (RCE) was used. Five different rotation rates were studied: 0 (or static conditions), 1000, 3000, 5000 and 7000 rpm. It was found that the turbulent flow increases the corrosion rate and the electrochemical corrosion process is influenced by a mass transfer process on the cathodic kinetics.
