| Abstract: | To ensure the safe operation of the special shape pressure pipe,an inspection method is brought forward in this paper regarding special shape pressure pipe that has lasted over 20 years. Firstly,through the thickness and hardness measurement the basic situation of the material is determined; secondly,based on the finite element method a dangerous area is analyzed and judged; finally,a acoustic emission method is used in real-time detection and analysis of the dangerous area. The results showed that this method can not only judge the reliability and security of the dangerous zone of but also provide some reference for the complex pipeline inspection in the future. |
