Why and How Did a Multi-layered Vessel Explode?

摘要：

　　The layered cylindrical shell is one of important structures of high pressure vessels.From 1977 to 2005 there were 8 urea synthesis reactors exploded.Seven of them were layered cylindrical shell structure.Therefore, there will be much more issue come out and waiting for us to study and explore.In this paper, we take the urea synthesis reactor exploded in 2005 in China as an example, to study why and how a multi-layered exploded.Through the research work, we not only concluded why and how a multilayered vessel exploded but also established a method to analyze the serious explosion accident of complex vessels such as urea reactors.
