摘要
某反应釜的一个异径三通管两侧出现了裂纹,导致反应釜不能正常使用,影响生产,且存在严重的安全隐患。现对异径三通管进行宏观观察、化学成分检测、硬度测量、扫描电镜形貌观察、裂纹腐蚀物能谱分析及金相组织分析等,从实验结果可以判断异径三通管相贯处存在应力及腐蚀性氯离子,形成了应力腐蚀而导致开裂。本文给出了合理化建议。
The cracking of several reaction kettles with reducing tee was occurred.It's determined that the cracking is caused by stress corrosion cracking with studying for the cracking section using chemical component measurement,SEM,corrosion analysis,metallographic microscopic analysis,etc.Additionally,some reasonable suggestions are provided in the paper.
