The theoretical basis for the 100 millivolt (mV) cathodic polarization criterion. Effects of other factors such as temperature, mill scale, moisture, and anaerobic bacteria, polarization.
Or
NEW IN 2008. This report discusses the theoretical basis for the 100 millivolt (mV) cathodic polarization criterion; the effects of other factors such as temperature, mill scale, moisture, and anaerobic bacteria; measurement of the polarization, and the applicability of the criterion in situations such as areas susceptible to stress corrosion cracking; mixed-metal systems; and areas susceptible to stray currents. It also includes the results of an industry questionnaire on the use of the 100 mV polarization criterion and opinions on its effectiveness.
Corrosion associated with alternating current (AC) interference on buried steel pipelines. AC corrosion characteristics and proposed mechanisms. Approaches to protection and monitoring.
