摘要
文中对一起锅炉水冷壁管漏水案例进行了调查,通过磁粉检测、金相分析等方法对裂纹进行了分析,最终判定裂纹为碱性溶液中的应力腐蚀裂纹,并根据裂纹形成的原因提出了有针对性的预防措施。
In this paper, we investigate a case of the water wall tube leakage in a boiler. We draw a conclusion that the crack is stress corrosion crack in an alkaline solution by using magnetic panicle inspection andmetallographic analysis etc. We propose targeted preventive measures based on the cause of crack formation.
