Laser Pipe Profiling

The perfect system for a combination of CCTV inspection and laser pipe profiling in mainlines.

The KS 135 Scan has revolutionized the pipe profiling process using the “spinning laser” profiling technology. It is a 3 in 1 system, a single module upgrade to the L 135 crawler platform. Two laser diodes are integrated on either side of the conventional CCTV camera lens to perform three functions:

  • Conventional CCTV video pipe inspection
  • Laser profiling – precise measurement of diameter, deflection and deformation of pipe.
  • Crack & joint measurement

Advantages of the Rausch Laser Profiler
  • Quick connection & easy setup
  • Application CCTV-inspection from 135mm
  • Pan and tilt camera, infinite tilt (using slip ring), pan 280°
  • Permanent upright picture
  • Direct & highly accurate measurements
  • No field calibration necessary
  • Continuous pressure monitoring
  • Complete report integration in PipeCommander software
  • No interference from sensors in the field of view
  • Can be evaluated on the vehicle

How it Works

The Rausch Laser Profiler features two laser diodes that are integrated into the KS 135 Scan camera head. When these laser diodes project laser dots onto the inner pipe wall, the camera head rotates to measure the diameter and all changes thereof via triangulation calculations. This method is called the “spinning laser” laser pipe profiling technology.
Working in conjunction with the PipeCommander software, the comprehensive scan generates easy to use reports to profile the pipe.

Detailed Operation

On the way into the pipe, the system is used to perform conventional CCTV video inspection, as well as measuring all joint widths. In addition, individual laser measurements can be taken at any time to determine the actual pipe diameter and deflection, called a single point scan. These diameter and deflection measurements then become a part of the inspection report.

On the way out of the pipe, the system performs a “spinning laser” scan of the entire pipe length. The camera head swivels perpendicular to the pipe wall and rotates at a defined speed. Via triangulation the Scan software continuously calculates the precise pipe diameter and all deflections and deformations in the pipe profile. Once the run is completed, the software instantly generates graphs in 2- and 3-D. These graphs show any deflection, the average pipe diameter, and the inclination slope of the line.

The 3D viewer shows the measurement as a three-dimensional pipe with all deformations. In addition to the 3D pipe in which deformations are color-coded, depending on the thickness, a round graphic is displayed on the right-hand side, which represents a section at the currently selected point in the pipe.
Below the 3D view is a planar representation of the pipe, in which the texture is drawn out as a surface. The red bar shows the current position of the 3D view.
