Description

[0002] In the modern industrial system, pipeline transportation as a kind of efficient, continuous material conveying mode, is widely used in petroleum, chemical industry, mineral, food processing and many other industries. However, pipeline inevitably suffers from wear and tear in the long-time, high-load transportation process, and its wear degree is directly related to the safety, reliability and service life of the pipeline transportation system. Especially when the transported material contains corrosive medium of different concentrations or particle of different sizes, the wear condition of the pipeline is more complex and variable, which is difficult to accurately predict and control.

[0003] At present, the technical means for monitoring and preventing pipeline wear known by the inventor mainly have the following limitations:

[0004] Manual inspection and sampling detection: the traditional method relies on manual regular inspection, measures the wall thickness by intercepting pipeline section or punching sampling to evaluate the wear condition of the pipeline. This method not only has high labor intensity and cost, but also is difficult to realize real-time and continuous monitoring, and cannot respond to sudden wear condition in time, which has great safety hazards. In addition, the sampling process itself may also cause additional damage to the pipeline.

[0005] Experience-based replacement: another common method is to replace the pipeline regularly according to the service life guidance provided by the pipeline manufacturer. However, due to the diversity and uncertainty of the transported material, especially the fluctuation of factors such as material concentration, particle size and flow rate, there is a significant difference between the actual wear rate of the pipeline and the expectation, and this "one-size-fits-all" replacement strategy often causes resource waste or fails to replace the severely worn pipeline in time, thereby increasing the risk of pipeline burst and material leakage.
