Within the last few years, experimental and theoretical investigations of the electrochemical behavior of these corrosive environments suggest that the buffering effect arising from the dissociation of weak acids at the vicinity of metal surface...

... ABSTRACT The current understanding of the corrosion mechanisms in H 2 S containing environments is based on the direct electrochemical reduction of H 2 S as the main contribution of this species to the corrosion process. Such an argument has been developed based on the distinctive behavior...

...: lightweight equipment, low alloy steel, wet H2S service, welding, SA-533 type E INTRODUCTION Weight reduction of more and more complex oil and gas production facilities has gained importance, especially for FPSO or FLNG units.
