[0048] In some embodiments, the passive MEMS sensor of the present invention may be a surface acoustic wave MEMS sensor. Figure 2 Spot welding can be used. When the pipeline is formed from a steel plate into a pipeline, multiple passive MEMS sensors 201 are installed on the inner wall of the pipeline respectively. For example, they are installed at 0 degrees, 90 degrees, 180 degrees, and 270 degrees inside the pipeline respectively. The installation interval can be freely set according to the length of the pipeline, and this application does not make any specific restrictions.

The pipeline anti-corrosion adopts the 3PE method. After the anti-corrosion layer is installed, a flexible sensor is installed on the surface of the anti-corrosion layer. After all the sensors of the two sections of sub-pipelines are installed, the two sections of sub-pipelines are welded together. At the welding point, the cross-weld strain sensor is first installed, and then the anti-corrosion layer is installed at the welding point. The flexible sensor is installed outside the anti-corrosion layer, and the distributed sensor and point sensor are connected at the connection point using a sensor connector to complete the processing of the natural gas intelligent pipeline.
