Technical Considerations on the Use of the 100mV Cathodic Polarization Criterion

摘要

The 100mV cathodic polarization criterion is being used more extensively on piping in the oil and gas industry which has prompted a discussion on the limits of its use. This paper summarizes the technical literature on the validity of this criterion with respect to elevated temperature, sulfate reducing bacteria, mill-scale, type of metal, mixed metal structures, stress corrosion cracking, soil moisture, and AC corrosion.
