In this paper , the mechanism and forming process of the cracks in view of the stress corrosion were analyzed accounting for the pressure vessels working in the atmosphere of wet hydrogen sul - phide , sodium hydroxide or liquidized ammonia
本文分析了压力容器及设备在湿润硫化氢、氢氧化钠溶液和液氨介质中应力腐蚀开裂的机理和应力腐蚀开裂的过程。
The paper mainly discussed the reasons of stress from liquid ammonia pressure vessel causing crack through examing data and experimental results and analysing relevant referential documents and materials , taking 1200 ammonia vessel ' s crack and leaking in a certain fertilization company as an example : there existed remaining welding , stress in the equipment ; there existed a stress decaying surrounding , i . e . , moisture 0 . 2 % , and temperature > - 5 with o2 or co2 inside ; the higher the intensity of raw materials , more possible it was to have stress decaying crack
摘要以某化肥公司1200氨冷器壳体开裂泄漏的失效分析为例，通过对检验数据和结果及有关文献资料的分析研究，探究了液氨介质压力容器产生应力腐蚀裂纹的原因：设备中存在较高的焊接残余应力；液氨介质具备应力腐蚀环境，即含水量0 . 2 % ，且有空气（ o2或co2 ）污染（或掺入），使用温度高于零下5 ；母材强度越高，应力腐蚀裂纹产生的倾向就越大。
