锅炉汽包接管断裂失效分析

Rupture Failure Analysis of the Steam Tank Nozzles of a Boiler

对汽包上连接安全阀管路接管的断裂失效原因进行了综合分析 ,在排除了可能引发事故的诸多因素之后 ,找出了断裂发生的根本原因是由于安全阀排气管路的出口方向在设计上是不合理的 。

A comprehensive analysis was made of the rupture failure causes of the nozzles connecting the tubes of the safety valve in the steam tank of a boiler. It was found that the fundamental rupture reason was that the design of the outlet direction of the discharge duct of the safety valve was unreasonable after disposing of many possible factors, and some improvement methods were proposed.
