[0002] High-energy pipelines are prone to cracks under the influence of high temperature, high pressure, vibration and other factors, which can lead to rupture and cause safety accidents, so they need to be monitored and evaluated. There are many high-energy pipelines involved in the nuclear power, chemical, cement and other industries.
