Pipeline surveys allow us to effectively evaluate integrity issues

Pipeline Surveys

Corrpro has been performing pipeline surveys for more than 50 years. In the last 10 years, we have effectively evaluated more then 250,000 miles of pipeline. Corrpro has the trained, OQ qualified personnel to field dozens of survey crews, and just as importantly, the equipment and instrumentation to properly and cost effectively perform the work. The quality of our survey work is in the pipeline industry and incorporates the full spectrum of survey techniques.

  • Close Interval Pipe-to-Soil potential surveys (CIS)
  • DC Voltage Gradient - (DCVG) surveys
  • AC Voltage Gradient - (ACVG) surveys
  • Electromagnetic surveys - CorrScan and current mapper/PCM
  • Sub-Meter GPS locating depth-of-cover
  • Continuous soil resistivity surveys (electromagnetic ground conductivity)
  • Linear polarization resistance corrosion rate measurements
  • Stress Corrosion Cracking (SCC) investigations
