The facilities of phase two of the Eastern Siberia-Pacific Ocean (ESPO PS-2) oil trunk pipeline which is operated by Transneft Far East for oil transportation are undergoing scheduled inspection using a next-generation in-line ultrasonic defectoscope.
From the beginning of this year the 48-DKP ultrasonic defectoscope inspection unit developed by Transneft Diascan has inspected the state of the pipeline section from oil pump station (PS) No. 21 (Skovorodino, Amur Region) to PS No. 30 (Obluchie, the Jewish Autonomous Region). Having half as many transducers as the previous unit versions and an improved resolution capacity of the measuring system as compared to such previous versions, the unit is able to detect crack-like defects, longitudinal and transverse defects, defects in spiral welded seams as well as defects of any other direction in respect to the longitudinal axis of the pipe.
Transneft Far East carries out monitoring of the oil transportation pipeline state on a regular basis using modern specialized inspection equipment which ensures high level of production process reliability and security. Preventive inspection of the ESPO-2 sections using the 48-DKP defectoscope is to be completed during the current year.
ESPO-2 is 2,047 km long, the pipeline runs along the territory of four federal subjects located in the Far East: Khabarovsk and Primorsky Regions, the Jewish Autonomous Region and Amur Region. The oil trunk pipeline transports the raw material to the Asian and Pacific markets and oil refineries of the Russian Far East.
