If the pipeline suddenly cracks or bursts, the production is seriously affected, and the injury and death of personnel are possibly caused. Therefore, the hidden danger of the steam pipeline is found in time, and the hidden danger early warning becomes very important.
The foregoing is not necessarily a prior art, and falls within the technical scope of the inventors.
