Abstract: In order to increase the ability of ultrasonic inline inspection tools to detect the defects that can lead to emergency situations on pipelines, the directions of the development of these devices are defined on the basis of the analysis of various sources. The need of increasing the resolving power of the measuring system in the circumferential and axial directions was revealed, as well as the need to use modern means of signal processing of ultrasonic sensors. Besides, in order to maintain good contact of the sensor carriers with the surface of the pipeline in the places of its deformation, as well as their optimal location relative to the testing object the need to improve such sensor carriers was also revealed. This will allow detecting and measuring defects such as scratches, metal losses, delamination, including those located on dents and corrugations.
There are the results of the implementation of an upgraded ultrasonic pipeline inspection gauge produced by Transneft Diascan, equipped with an adaptive carrier which has adaptive slats with sensors on movable suspensions. Successful tests of the upgraded devices confirmed the correctness and the effectiveness of the design decisions adopted.

Keywords: ultrasonic inline inspection tool, measuring system resolution, dents influence on sizing defects within pipe wall, wall thickness measurement, immersion layer, diagnostics.
