Let’s give praise and encouragement to the achievements made in China’s chemical engineering technology and equipment; your participation in discussions is the greatest encouragement. **********************【Ten Years of Progress in Chemical Engineering Equipment】Regular updates and summaries are available; feel free to join the discussions: https://bbs.hcbbs.com/thread-3576046-1-1.html ***************** The PIGPROX electromagnetic eddy current pipeline inspection robot, which features completely independent intellectual property rights in China, has been successfully used for inspecting pipelines in oil and gas fields. On April 22, 2022, Sichuan Deyuan Pipeline Technology Co., Ltd. and the University of Electronic Science and Technology of China’s Deyuan Pipeline Inspection Technology Research Center, after three years of research, developed this first domestic electromagnetic eddy current pipeline inspection robot of its kind. It was used to inspect oil and gas transmission pipelines with diameters of Φ168 and Φ323 in China’s northwestern and southwestern oil and gas fields. The biggest challenge in this internal inspection task was that the pipes could only be fed using ball valves, which imposed strict requirements on the size of the inspection robots. Engineers from Deyuan Pipeline Technology optimized the design of these inspection robots based on the dimensions of the customer’s ball valves and the conditions of the pipes, ensuring smooth feeding and retrieval processes as well as high efficiency, thereby providing a solid foundation for the on-site inspection work. The PIGPROX electromagnetic eddy current pipeline inspection robot is a new type of highly integrated and compact online electromagnetic eddy current internal pipeline inspection technology developed by Deyuan Pipeline Technology in collaboration with the University of Electronic Science and Technology, aiming to achieve international advanced levels of technology. To date, relevant intellectual property rights for the sensors, electronic hardware, mechanical structures, artificial intelligence algorithms, and software have been applied for; 5 invention patents, 2 PCT patents, 9 design and utility model patents, and 2 software copyrights have been filed. The internal inspection operations carried out on the Φ168 shale gas transmission pipeline and the Φ323 natural gas transmission pipeline represented the first successful use of the PIGPROX electromagnetic eddy current internal inspection robot in pipelines equipped with start-up valves. This successful application demonstrated the excellent performance of the PIGPROX electromagnetic eddy current pipeline inspection robot in terms of mechanical structure, high passability, signal acquisition, and stability; it is fully capable of handling operations in pipelines with start-up valves, passing through 1.5D bends without issue, and generating inspection data with a high signal-to-noise ratio and high clarity. Since May 2021, the PIGPROX electromagnetic eddy current pipeline inspection robot has been used to conduct inspection tasks in oil and gas transmission pipelines with diameters of Φ159, Φ168, Φ219, Φ273, Φ323, and Φ406 in various oil and gas fields. It has been used with both standard sending cylinders as well as non-standard ones and sending valves, and it has overcome the complex challenges associated with inspecting such pipelines. This demonstrates the excellent suitability of the PIGPROX electromagnetic eddy current pipeline inspection robot, which features independent intellectual property rights in China, for inspection work in oil and gas transmission pipelines of different diameters, under varying pressures, in conditions of low pressure and low flow rates, with many bends, multi-phase media, and complex internal structures.
