The super project spanning 8,000 kilometers has the highest transmission pressure and the longest distance in the world. The China-Russian East Route natural gas pipeline project(Сила Сибири) is under construction. The NDT2NDT pipeline girth weld ultrasonic testing equipment is on the scene, which strictly controls the welding quality of the Century Project.
The China-Russian East Route Natural Gas Pipeline Project(Сила Сибири) has a total length of 5,111 kilometers in China, starting from Heihe City in Heilongjiang Province in the north and passing through Hebei, Tianjin, and Shandong. As the first onshore natural gas cross-border strategic channel in Northeast China, the commissioning of the China-Russian East Route Natural Gas Pipeline is of great significance to optimizing China’s energy consumption structure and alleviating air pollution along the route.
Therefore, the quality management of the China-Russian East Route pipeline construction is particularly strict. In order to keep up with the international advanced level, the China-Russian East Route comprehensively promotes the application of new technologies such as fully automated welding, AUT, and mechanized anti-corrosion patching. The non-destructive testing of all girth welds is the most important control like, the inspection results of each weld are organized by the inspection unit, supervisor, research institute, fourth-party inspection unit and foreign consulting experts to conduct re-evaluation, and the coverage rate of the assessment has reached 360%.
NDT2NDT is a leading manufacturer of AUT testing equipment in China. Its AUT testing equipment is used in the third section of the (Yongqing-Shanghai) Anping-Taian section of the route project to detect welds which specifications are 1219*22, 1219*27.5, 1219*18.4 , and it detected 2875 welds. The fully automatic testing equipment greatly improves the testing efficiency. The cable-free design of the scanning device greatly improves its flexibility under various harsh working conditions on site. PA+TOFD ultrasonic probe disc can be used for simultaneous detection of phased array and TOFD, which can more guarantee the accuracy of weld detection.
