Description

Technical Field

[0001] The present invention belongs to the field of pipeline monitoring, and in particular relates to an intelligent pipeline corrosion monitoring system. Background Art

[0002] The development of modern society is inseparable from fossil fuels. While my country possesses abundant reserves of resources like oil and natural gas, their distribution is uneven. As demand for these resources continues to grow across the country, the pipeline transportation industry has flourished, and the number of pipelines used to transport oil and natural gas has also increased. By the 20th century, pipeline transportation had matured to become one of the five major modes of transportation, alongside road, rail, aviation, and shipping. Today, pipelines can transport not only oil, natural gas, water, and chemical liquids over long distances, but also energy sources like coal slurry, coalbed methane, and ore. Pipeline transportation plays a crucial role in the energy transportation system.

[0003] Compared to other modes of transportation, pipeline transportation is more efficient and safer. Specifically, pipeline transportation's advantages include: high efficiency and low labor and material costs. For the same oil and gas shipment, rail transportation costs double the cost of pipeline transportation. Pipeline transportation is less susceptible to environmental influences. Once laid, the pipeline is minimally affected by terrain and weather, making it more sustainable than other modes of transportation. Laying a pipeline with comparable efficiency requires significantly less work than building a railway, and most pipelines are built underground, conserving more land than other modes of transportation. Due to the continuous expansion of pipeline networks, pipeline accidents have become a potential threat to socioeconomic activities and threatens human life and property. One of the key causes of pipeline explosions is corrosion.

[0004] Physical monitoring and chemical monitoring are the most common monitoring methods used in pipeline corrosion status monitoring operations. The former mainly reflects the actual corrosion status by measuring parameters such as resistance, heat conduction, and electromagnetics at the rusted location. Specifically, it mainly includes eddy current method, X-ray method, and infrared thermal imaging method. Although the physical monitoring method has been relatively widely used in actual operations, combined with the analysis of the actual working status, the chemical monitoring method is still more advantageous. It is worth noting that the chemical monitoring method can not only accurately determine the degree of corrosion of pipelines and related equipment, but also accurately display the intrinsic mechanism information of the actual corrosion process. However, conventional physical monitoring methods or chemical monitoring methods cannot monitor pipelines in real time. Once a fault occurs, it cannot be discovered and handled in time, which can easily cause huge losses. Therefore, there is an urgent need for an intelligent pipeline corrosion monitoring system to solve the above problems. Summary of the Invention
