压力容器的破裂会造成严重的事故,尤其在石化企业。这就要求从事压力容器的作业人员及其相关管理人员在压力容器安全技术培训中,了解和掌握压力容器破裂的特定规律,以便正确有效地找到避免压力容器破裂的措施和办法,从而减少和避免破裂爆炸事故的发生。根据压力容器的破裂特点,压力容器的破裂形式可分为韧性破裂、脆性破裂、疲劳破裂、腐蚀破裂和蠕变破裂等。这些破裂形式的发生机理、破裂特征及产生原因所涉及到的内容专业性很强,难懂,而且比较枯燥,对于现场操作人员的培训不易被接受。因此,在压力容器 Cracking of pressure vessels can cause serious accidents, especially in petrochemical plants. This requires pressure vessel operators and their related managers in the safety training of pressure vessels to understand and grasp the specific rules of pressure vessel rupture in order to correctly and effectively find ways to avoid rupture of pressure vessels and ways to reduce and avoid Burst explosion occurred. According to the rupture characteristics of pressure vessels, the rupture forms of pressure vessel can be divided into ductile fracture, brittle fracture, fatigue fracture, corrosion fracture and creep fracture. The causes of these rupture patterns, rupture characteristics and the causes involved in the content of the highly specialized, difficult to understand, and more boring, for the training of field operators is not easy to be accepted. So in the pressure vessel
