Inspection of long pipes with the Guided Wave technique

A check to identify corrosion on long pipes that are not accessible and without removing the insulation

ISPECO with the GUIDED WAVES inspection technique and the Wave Maker G3 instrumentation is able to identify corrosion phenomena on pipes in operation, even on sections that are not directly accessible and without having to completely remove the insulation where it is present.

The scan result is a screening of the state of the pipe with the possibility of identifying:

  • external corrosion;
  • internal corrosion.

The check can be carried out on lines with temperatures up to 120 ° C and while the system is running.

The length of pipe that can be inspected on each side, for each station, is variable; indicatively the following can be examined:

  • up to 100 m in ideal conditions (straight pipe, simply supported and uncoated)
  • 10 m for recently or heavily corroded bituminous pipes
  • up to the first flange or the second bend.

The examination allows to identify signals coming from geometric variations (detachments, welds, supports, flanges, etc.) and to accurately identify areas with variations with respect to the cross section of the tube greater than 5%; defects of 2% are identified in particularly favorable conditions.

The control is particularly used for:

  • underground lines
  • insulated lines (it is necessary to remove the insulation only for the placement of the ring)
  • jacketed sections of line
  • road crossings
  • lines on pipe rack
  • airlines
