The average annual scope of inline inspection work covers some 60 000 km of pipelines. The surveys are done using multichannel BGTs fitted with navigation modules, WM and CD ultrasonic defectoscopes, MFL and TFI magnetic defectoscopes, combined magnetic and combined magnetic ultrasonic detectoscopes, as well as defectoscopes used to reveal randomly oriented defects. By their performance parameters, some ILITs manufactured by Transneft Diascan are unique and unrivalled around the world.
