Abstract
Coupled multielectrode array sensors made of Type 316L stainless steel, AL6XN and Alloy C-276 alloys were used as real time-sensors to monitor localized corrosion in a side loop of a process stream in a chemical plant. The pitting corrosion rates measured from the probes made of stainless steel and nickel-chromium alloys are consistent with the pitting resistance equivalent numbers of the alloys and with the plant experience. The pitting rate obtained from the long-term measurement is in good agreement with the actual corrosion rate obtained from the posttest surface examination of the probes.
