โœฆ Synopsis

Abstraet--A Fluid Flow Test Rig has been designed and commissioned to simulate corrosion occurring in geothermal steam pipelines. The test rig was used to evaluate the effectiveness of a variety of corrosion monitoring techniques for application to full-scale pipelines. Although unsuccessful, the thin layer activation method, which is based on the conversion of Fe to 56Co upon irradiation with high-energy protons, showed potential for application to geothermal systems. Corrosion rates measured in the test facility were similar to those estimated for the Ohaaki (New Zealand) steam pipelines after three years of service.

Advanced on-line corrosion monitoring techniques were used to characterize the corrosion damage sustained by mild steel in cooling emulsions. While the general corrosion rates of mild steel were extremely low at under 2 milli-inches per year thickness loss, the electrochemical measurements indicated

In this study, a modified electrochemical noise (EN) technique was used to monitor uniform corrosion and pitting corrosion. In the EN technique, one working electrode is coupled to a microelectrode (e.g. Pt) through a zero resistance ammeter to sense current noise. Results show that the EN technique
