Transneft Diascan has put into operation its new Ultrasonic Defectoscope 20-DKP.00-00.000 for randomly oriented defects detection. The instrument was developed by the company’s engineers for inline inspection of oil and petroleum products pipelines with the diameter of 20 in.

The defectoscope is equipped with an ultrasonic metering system with WM and CD sensors with two angles for sending the ultrasonic signal into the pipe wall. The instrument design ensures multi-angle examination of slit-shaped defects of longitudinal and transverse orientation.

The development of the inspection tool started in November 2015 and was completed in October 2018. During the integrated testing, the instrument was checked for climatic (temperature from -40°? to 50°?) and mechanical exposures. The testing locations included the fluid test ground of Transneft Diascan and the functioning Ufa-West oil pipeline operated by Transneft Urals. The verification confirmed that the detectability and defects metering by the instrument were compliant with the terms of reference.

As of now, Transneft Diascan operates 5 ultrasonic defectoscopes to reveal randomly oriented defects in pipelines with the diameter from 20 - 48 in.
