Determination of oxygen limits for corrosion resistant alloys (CRAs) in oil & gas produced water based on electrochemical test methods Part 1: Crevice corrosion and repassivation potentials without oxygen

Stainless steels are frequently used in the oil & gas industry due to their excellent resistance against corrosion. In seawater and produced water, however, pitting and/or crevice corrosion can occur assuming the process conditions are outside the so-called “safe operation window” for the actual alloy. In produced water, oxygen content is one important process parameter. It is well known that in electrolytes with small amounts of oxygen (O2
