For diagnostics of pipeline, a set of high-resolution magnetic in-line inspection tools was developed. It allows detect any types of defects: general and pitting corrosion, longitudinally and transversely oriented grooves and cracks, ring seam and seam weld anomalies, artificial damages and metallurgical defects. Also with the help of InnerScan technology, defects are separated to internal and external.
Excessively high speed of in-line inspection tools movement reduces the reliability of identified defects, therefore in-line inspection tools with a diameter greater than 24” are equipped with active speed controllers that allow to maintain the speed of movement in a safety range.
