The Pipeline Defect Mapper

Cathodic protection (CP) is used throughout the world to protect pipelines from the corrosion caused by protective coating defects. To maximize the efficiency of the cathodic protection, and to minimize stray currents, the Corrosion Engineer’s challenge is to reduce the size and number of coating defects.

The Pipeline Defect Mapper (vLocDM) is an instrument designed and developed by Vivax-Metrotech to precisely locate and assist in evaluating such coating defects.

The profiling current can be applied at any CP point, the measurements are taken with a rugged hand-held receiver.

Results in the form of data or graphs (plots) can be viewed in real time on the vLocDM display – external datalogger and GPS – or during post processing at the office.

Pipeline Defect Mapper (vLocDM) features:

  • Sleek lightweight design
  • Rugged, custom carbon fiber and “ABS” housings
  • Color display
  • Dual core processor
  • Both alkaline and rechargeable batteries
