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】A continuously updated summary post – feel free to join the discussions: https://bbs.hcbbs.com/thread-3576046-1-1.html ***************** Recently, the new generation of pipeline inspection devices developed by the 22nd Research Institute of China Electronics Technology Group – the “Pipeline Pig” – successfully passed all tests at the test site in Dazhou, Sichuan. 　　The inspection equipment integrates four core technologies: electromagnetic eddy current, geometric deformation, distance measurement, and inertial navigation. It is capable of accurately detecting various minor defects in pipelines, and boasts significant advantages such as fast inspection speed, high efficiency, and low costs. Its inspection accuracy and reliability are at the international leading level. 　　It not only fills the gap in the field of pipeline inspection equipment within the CETC Group in China, but also provides strong technical support for the safe operation and intelligent management of oil and gas pipelines in our country. 　　At present, China has a vast network of infrastructure pipelines; the total length of oil and gas transmission pipelines amounts to 240,000 kilometers. Moreover, within tens of thousands of square kilometers of urban underground spaces, the coverage of these pipelines continues to expand. However, as pipelines age, safety hazards such as corrosion and cracks become increasingly prominent, resulting in economic losses of billions of yuan each year due to pipeline failures. Therefore, accurate and efficient in-house testing technologies as well as high-quality domestic alternative equipment are urgently needed. 　　In the future, the 22 institutions will continue to focus on digital technologies for underground spaces, fostering cutting-edge technological achievements through top-level planning, coordinated research and development, and resource integration, in order to create new drivers for growth. We will continue to focus on the field of pipeline internal inspection, drive continuous improvement of \"pipeline pigs\", expand their application scenarios, and develop a comprehensive set of technologies for pipeline internal inspection. This will provide essential equipment support for the safe and efficient operation of global energy transmission systems as well as for improving the management level of urban infrastructure.
