摘要
通过宏观观察、理化检验分析及管线的振动评估来分析出水管漏水断裂的失效原因。分析结果表明出水管是在振动载荷和环境腐蚀共同作用下导致的腐蚀疲劳断裂,并针对失效原因提出了相应的建议。
With macro graphic examination,physical and chemical inspection and piping vibration evaluation,the causes of rupture in the outlet-pipe of seal cooler were analyzed.The results showed that rupture of the outlet pipe was due to corrosion fatigue resulted from the interaction of vibration and environmental corrosion.In addition,some suggestions are put forward according to the causes.
