Corrosion sensors and electrochemistry-based corrosion measurement technology were used to study internal corrosion of environments similar to those in natural gas transmission pipelines. Field tests were conducted at a gas gathering site. Test locations were selected in environments consisting of dry/moist natural gas and the hydrocarbon/water mixture removed from natural gas. Sensors were made using A106 pipeline steel in the form of flange probes. Linear polarization resistance, electrochemical noise, and harmonic distortion analysis were used to measure corrosion rates, Stern-Geary constants, and pitting factors. Results show that the measurements were sensitive enough to detect small rates of corrosion in the selected environments.
