Flawed Pipeline Spools for In-Line Inspection (ILI)
Validation and calibration spools for ILI performance verification.
Our bespoke validation and calibration spools are designed to help you gain a comprehensive understanding of your ILI results, increasing the probability of flaw detection and accuracy.
We manufacture spools of up to 30ft in length, with flaws connected to the OD, ID or mid-wall. These can all be positioned within the electric resistance welded (ERW) seam, parent material or circumferential welds.
We offer a large variety of flaw types in any geometry and will work with you closely to determine the type, size, and location of flaws required to be implanted within the spool. We work hard to ensure we meet your project requirements related to your integrity management objectives to the highest standard.
Eddy Current Array (ECA) crack fields
Sonaspection recognizes the limitations of some weld-induced flaws for certain NDE methods and is constantly developing market-leading techniques to overcome these. For Eddy Current Array (ECA), Sonaspection has took on the challenge by creating crack fields with known lengths, heights and locations made without interfering with the performance of the NDE tools applied.
