On October 16, 2015, an internal magnetic flux leakage detector for submarine pipelines developed independently by China was successfully tested at BZ34-1 oilfield in the Bohai Sea recently, and complete and effective data were obtained. The performance parameters of the detector reached the advanced level of the same kind of products in the world. Wang Jianfeng, head of the China National Petroleum Project, said: "From the test data, the detection rate of defects, the calibration accuracy of the length, width and depth of defects, and the identification of defects at home and abroad are basically in line with the mainstream indicators of domestic detectors. If the domestic self-developed detectors are widely used, only CNOOC's 6,000 km submarine pipeline can save 80 million yuan annually. About RMB."
Therefore, the research and development of magnetic flux leakage testing technology have brought great breakthroughs to China's submarine pipeline Market and greatly improved industrialization.
In recent years, China has accelerated the construction of the oil and gas pipeline network, and the safety of oil and gas pipelines has received widespread social attention. The pipeline inspection equipment and technology is an important means to prevent pipeline accidents.
