ACVG DCVG Gradient Surveys | Legacy Integrity

Gradient Surveys

Legacy Integrity offers gradient survey services aimed at assessing the integrity and effectiveness of cathodic protection systems for pipelines. These services involve the measurement and analysis of voltage gradients along the pipeline route to identify areas where corrosion protection may be inadequate or compromised.

Legacy Integrity's gradient survey services are conducted by experienced professionals using cutting-edge equipment and adhere to industry standards and regulatory requirements. By leveraging their expertise in gradient surveys, Legacy Integrity helps clients maintain the reliability and safety of their pipeline assets by ensuring effective corrosion protection measures are in place.

Key components of Legacy Integrity's gradient survey services include:

Direct Current Voltage Gradient (DCVG) Survey: Legacy Integrity conducts DCVG surveys to detect and pinpoint areas of coating defects on the pipeline, which can lead to corrosion. By measuring voltage gradients, they can identify locations where the protective coating may be damaged or ineffective.

Alternating Current Voltage Gradient (ACVG) Survey: ACVG surveys are performed by measuring voltage gradients induced by alternating current sources. These gradient measurements identify coating anomalies and helps Legacy Integrity assess the effectiveness of cathodic protection while identifying any areas where corrosion mitigation measures may need improvement.

Soil Resistivity Testing: Legacy Integrity assesses the electrical resistivity of the surrounding soil to determine its corrosive potential and optimize cathodic protection strategies. By understanding soil resistivity, they can better tailor cathodic protection systems to mitigate corrosion risks effectively.

Data Analysis and Reporting: Following data collection, Legacy Integrity employs advanced analytical techniques to interpret the results and generate comprehensive reports outlining the condition of the pipeline and any recommended remedial actions. These reports provide valuable insights into the performance of cathodic protection systems and help clients make informed decisions to enhance pipeline integrity.
