摘要
介绍了末过设计参数,以及爆管的外表特征,对原始爆口进行光谱、硬度、力学等实验,最后通过金相组织分析得出结论为长期超温爆管。根据现场情况对末过入口管屏进行更换,并提出建议和预案。
This article introduces Introduced too late design parameters,as well as burst pipes look like,The original spectral population explosion,hardness,mechanical and other experimental,Finally,microstructure analysis concluded that the long- term over- temperature burst pipes. According to the situation on the end of the inlet tube screen had to be replaced,And to make recommendations and plans.
