Evaluates a method for obtaining accurate measurements of the pipe-to-soil potential on a bare pipeline in a high-resistivity environment with the ultimate objective of using the method to provide information for preventing stress corrosion cracking.
This project was initiated as a result of the findings of earlier research on PR-3-93, "Investigation of Techniques to Determine the True Pipe-to-Soil Potential of a Buried Pipeline: Supplementary Studies". The research on project PR-3-93, conducted…
Pipe-to-soil potential measurements are the primary means for monitoring the effectiveness of cathodic protection systems. All criteria for cathodic protection employ, in one form or another, a potential measurement of the pipe with respect to a…
During a prior research program, a spiking phenomenon was identified that prevented the measurement of the off potential directly from the pipe-to-soil potential waveform. Furthermore, the spike made it impossible to measure an off potential during…
Pipe-to-soil potential measurements are the primary means for monitoring the effectiveness of cathodic protection (CP) systems. All criteria for cathodic protection employ, in one form or another, a potential measurement of the pipe with respect to a…
