Corrosion Mapping

Corrosion mapping can be used to map the variations within a material into a helpful colour coded map. The process can be performed with various techniques – typically utilising ultrasonics for thickness measurement information, in addition to our proprietary Low Frequency Electromagnetic Technique (LFET) technology which uses variations within magnetic fields to detect changes in the material.

Corrosion Mapping

Our ultrasonic based corrosion mapping tool provides high resolution corrosion detection for a variety of applications.

The technology can be applied to flat plate, pipelines, pressure vessels, storage tanks, columns and tubes >= 4 Inch diameter.

Benefits of Corrosion Mapping

  • Inspect a variety of wide variety of assets and materials
  • Fast scan speed up to 80mm/second
  • High Resolution Image – Sensor Resolution of 0.8mm
  • 50mm Scan Width with 64 element array
  • Adjust inspection angle quickly on the fly for different diameter scans
  • Handheld Portable Equipment
  • Inspect large areas quickly
  • Limited couplant required (light water spray)
  • Maximum Inspection depth of 80mm in Carbon Steel
  • Repeatable inspection

LFET Based Corrosion Mapping

Our Low Frequency Electromagnetic Technique (LFET) can be used in situations where surface condition is not appropriate for ultrasonics, where linings or coatings are present for example, or where large volume of scanning is required quickly.

LFET based corrosion mapping is typically used as a fast screening tool, allowing 100% coverage where ultrasonics would only inspect a small percentage in the same time frame. We then go back with ultrasonics to prove up any areas of interest.

Benefits

  • Inspect a variety of wide variety of assets and materials e.g. Boiler tubes, pipelines, storage tanks, pressure vessels, columns, flat plate
  • Variety of different width scanners for all diameter tubes / pipes
  • Variety of scanners for bends, ligaments, hard to access areas
  • Handheld Portable Equipment
  • Inspect large areas quickly
  • No couplant required
  • Inspect through linings and coatings, and through other materials

Comprehensive Reporting

You will receive a comprehensive inspectors report detailing results and the findings of the inspection. The standard of our reports is just one of the things that makes us stand out in the industry.
