Close Interval Survey
Legacy Integrity offers comprehensive close interval survey (CIS) services, ensuring the integrity and safety of pipelines. Our CIS services encompass a range of activities aimed at detecting and assessing potential issues within pipelines, including corrosion, leaks, and structural weaknesses.
Legacy Integrity's close interval survey services are conducted by CP trained professionals using state-of-the-art equipment and adhere to industry best practices and regulatory standards, ensuring the ongoing reliability and safety of pipeline infrastructure.
Key components of Legacy Integrity's CIS services include:
-
Close Interval Potential Survey (CIPS): This involves the measurement of pipe-to-soil potentials at closely spaced intervals along the pipeline route, helping to identify areas susceptible to corrosion.
-
Current Mapping (PCM / ACCA): Utilizing advanced techniques, Legacy Integrity maps the flow of electric current along the pipeline, aiding in the detection of areas prone to corrosion or coating damage.
-
Soil Resistivity Testing: assessing the electrical resistivity of the surrounding soil to determine its corrosive potential and optimize cathodic protection strategies.
-
Data Analysis and Reporting: Following data collection, we employ advanced analytical techniques to interpret the results and generate comprehensive reports outlining the condition of the pipeline and any recommended remedial actions.
