Pipeline transportation of oil and natural gas is one of the five major transportation industries in China, and plays a very important role in China's national economy. It is called the “energy bloodlineâ€. However, in recent years, pipeline safety accidents caused by pipeline damage frequently occur, especially the oil and gas spill accidents on the seabed, which not only caused incalculable losses to the national economy and the lives and property of the people, but also caused great harm to the environment. The international community has paid close attention to it.
"Under the seabed pipeline, it is difficult to treat and costly." Industry experts once described it. Due to the detection error of a submarine pipeline corrosion, the cost of pipeline reinforcement and re-maintenance is as high as 50 million yuan. Therefore, the prevention of "energy vascular" diseases has become a realistic issue.
Pipeline magnetic flux leakage detection technology is recognized as the most complete pipeline inspection method at home and abroad. At present, 90% of pipeline inspections in the world use this technology. It uses a pair of north and south magnetic poles to magnetize the saturated pipeline. There is a uniform magnetic field inside the pipeline. When there is a defect in the pipeline, there will be a magnetic field leakage at the defect. The corresponding leakage magnetic field detection is magnetic flux leakage detection. . It is like a full flow of water flowing through a water pipe. When a water pipe leaks or breaks, there will be water leakage at the damaged place.
However, due to the complicated application conditions and corrosion factors of submarine pipelines, the requirements for detector reliability and environmental adaptability are much higher than those of terrestrial pipelines. Even if the domestic technology pays great attention to this technology and has been tracked for more than 20 years, it has not been realized in the product. Make a breakthrough. Due to the gap between domestic testing technology and actual demand, “foreign physical examination†has long monopolized the medical examination market of China's submarine pipelines. Moreover, because foreign companies can determine the geographic coordinate information of pipelines and pipeline operation information through testing, the national oil and gas information is exposed to the risk of leakage. Moreover, the submarine pipeline enjoys a "foreign physical examination" service is not cheap, the price is as high as nearly 60,000 yuan / km.
Faced with the earlier starter competitors, 35 quickly researched and developed the pipeline magnetic flux leakage detection technology after receiving the project requirements. After a year and a half, 35 have produced prototypes of detectors with independent intellectual property rights. Zheng Li, the 29-year-old project leader, said: "Our detectors use oil and gas pressure to travel through the submarine pipelines and run down. Through high-precision magnetic flux leakage detection technology, we can capture and store corrosion and defects in the inner and outer walls of the pipeline. Information, to achieve accurate identification of the defect points, accurate positioning, to achieve expert-level testing."
After the application of the magnetic leakage detector inside the submarine pipeline, it can provide a complete set of pipeline inspection and evaluation services. Just like the medical examinations familiar to ordinary people, you can get a clear understanding of your physical condition, problems and treatment suggestions through the medical report issued. A precise medical report is an important basis for the health and repair of “energy blood vesselsâ€, which can achieve symptomatic medical treatment, avoid the loss of drugs and the loss and risk of using the wrong drugs.
"The detector has the risk of being stuck in the pipeline or disassembling in the pipeline, especially in the cornering and deformation of the pipeline, ensuring that the detector is safely passed." Zheng Li said: "It is also because of the high aerospace products. Reliability guarantee, our products have the ability to compete with foreign products. Moreover, our research and development is based on the needs of domestic pipelines, and can provide higher quality testing services."
At present, 35, 8 inch, the smallest diameter submarine pipeline for the detector development of the object, has broken through and mastered the key technologies. This is only the first step. The 35 follow-up will develop 10, 12, 14-inch series of submarine pipeline magnetic flux leakage detectors. Along with the first “Physicianâ€, the high-precision submarine pipeline online testing equipment serialization, high-precision land pipeline online testing equipment serialization, pipeline inspection data analysis services, and pipeline life assessment services will be formed one after another.
“The preparation for industrialization has been completed.†A person in charge of 35 said: “The 35,700 square meters of online testing system plant, 600 square meters of online testing system research and development center will be completed within two years, can provide a full set of pipeline testing Service, pipeline fatigue and life assessment services. Domestic submarine pipeline oil spill detectors replace foreign products, which is an embodiment of our military defense technology to expand into the national economy, and also aerospace science and technology 'big defense, big security, big integration, The manifestation of great development."
With less medical examination fees, shorter evaluation cycles, stronger confidentiality, and better user experience, the country is expecting the “local medical examiner†to get an early job.
