Its structure is relatively complex. It works in high-temperature, high-pressure, toxic and harmful environment, causing great harm. In practical application, due to the limitation of various conditions, pressure vessels often have many problems, such as cracking and deformation after long-term use. In order to ensure the safe use of pressure vessels for a long time, scientific prediction and repair must be carried out before failure occurs. This paper studies various defects and tests their characteristics, so as to improve the detection rate and ensure the safe use of pressure vessels.展开更多
