The PIPE SCANNER system is designed to perform a complete and accurate scanning of both the internal and external surfaces of pipes coming from decommissioning of nuclear power plants.

PIPE SCANNER is composed of:

  • a main rail
  • a support column equipped with two horizontal poles where the detectors are mounted
  • two movable pipe lodging supports with adjustable rotation devices

The measurement cycle is completely automatic, carried out by a PLC and managed by the software installed on the host PC. The touch-screen user interface allows the operator to set the input parameters, the measurement settings, and to start the automatic cycle. The system status is shown both on the display and by the built-in alarm column.

After loading the pipe, PIPE SCANNER runs a series of preliminary tests through optical devices, i.e. diameter and length measurement, and roughness check.

After all the preliminary checks have been carried out, the measurement cycle starts: the pipe lenght is automatically divided in portions to be scanned by the detectors, and the system acquires the radiometric data for each portion separately. The system can also detect hot spots of contamination.

At the end of the scanning a measurement report is produced. Safety devices and a perimeter infrared barrier prevent any dangerous man/machine interaction.
