笔者从事压力容器检验工作以来,发现过的安全隐患形形色色,各种各样,但压力容器筒体疲劳裂纹还是少见,总觉得有必要提一下,以飨同行。1设备概况该容器为氢氮压缩机附属高压容器——七段缓冲器,于1968年制造,1970年投入运行。该设备安装于室内无雨水和大气腐蚀。设计压力:32MPa,设计温度:150℃,工作压力:31.4MPa,工作温度:140℃左右,工作介质:氢气、氮气。容器外径为φ299mm,内径为φ199mm,公称厚度为50mm。筒体材质为20G高压无缝钢管。由于年限太久,出厂资
I engaged in pressure vessel inspection since the security risks found in all kinds, but pressure vessel barrel fatigue cracks are rare, always felt it necessary to mention, to 飨 counterparts. 1 Equipment Overview The container is a hydrazine compressor attached to the pressure vessel - seven-segment buffer, manufactured in 1968, put into operation in 1970. The device is installed indoors without rain and atmospheric corrosion. Design pressure: 32MPa, design temperature: 150 ℃, working pressure: 31.4MPa, working temperature: 140 ℃, working medium: hydrogen, nitrogen. Container diameter φ299mm, diameter φ199mm, nominal thickness of 50mm. Cylinder material is 20G high pressure seamless steel pipe. As the age is too long, the factory capital
