Integrated Cathodic Protection (CP) and Coating Surveys

In 2017, Allied Engineers introduced the eXternal Line Inspection (XLI in collaboration with PureHM) in India and Middle East region to provide “most authentic” CP and Coating survey results which are not limited to surveyor’s subjectivity.

AE has already performed XLI surveys in excess of 3,000+ Kms and have trained several certified teams for meeting the Client demands for XLI.
The XLI equipment collects encrypted data with raw waveforms similar to an ILI or a Hydrotest assessment.

Performing eXternal Line Inspection (XLI) with simultaneous, continuous and encrypted “All in One” following surveys:
XLI collects up to ten (10) data sets by walking ONLY ONCE over the complete pipeline ROW

  • Differential Global Positioning System / Geographic
    Information System (DGPS/GIS)
  • Close Interval Potential Survey - DC (CIPS-DC)
  • Close Interval Potential Survey - AC (CIPS-AC)
  • Direct Current Voltage Gradient (DCVG)
  • Alternating Current Voltage Gradient (ACVG)
  • Alternating Current-Current Attenuation / Current
    Attenuation Test (ACCA/CAT)
  • Depth of Cover, Elevation, Pipeline Profile
  • Gas Leak Detection (GLD) for Gas pipelines
  • Continuous Soil Resistivity (Optional)
  • Pipe Wall Assessment (PWA) using the Large
    Standoff Magnetometry (LSM) method (Optional)
