Automated Laser Profilometry

Automated Laser Profilometry

Automated laser profilometry helps pipeline owners and operators determine corrosion depths on large external sections of pipeline. This proven technology provides fast, accurate data, which allows operators to identify and address pressing corrosion issues before they become critical.

To detect and measure corrosion, laser scanners create two-dimensional surface profiles as they move along the pipeline’s outer surface. The laser scanning system then compiles the resulting data to create a contour map of the pipeline’s surface corrosion that can be analyzed with computer software. In the end, operators have a detailed picture of your corrosion situation that they can use to plan the proper course of action.

Because the laser scanning process is highly repeatable, the position and size data of each flaw can be compared to scans of the same area, allowing you to track and monitor growth.

Best used for: dents, large external areas of pipeline, or any external anomaly in which permanent documentation is desired

Key features:

  • Permanent documentation of the corrosion depth measurements, along with screen shots of the system’s 2D scans.
  • Through-thickness profiles available.
  • Software offers option of creating a 3D model of the evaluated piece that you can use to augment analysis and reporting.
  • Spreadsheets with the laser scan data can be directly downloaded into pipeline remaining strength (RSTRENG) software.
  • Scan data can be used to determine corrosion cells’ proximity to one another and whether they are expanding.


  • What are the benefits of automated laser profilometry? Benefits include high-speed inspection, accuracy, and repeatability.
  • What is the published accuracy tolerance? The accuracy of depth measurements are within 0.002 inches.
