近十年来,小合成氨厂的变换工段,普遍推广了远红外电加热器,我厂也不例外,套用了兄弟厂图纸,自制了这台设备。其结构尺寸如图所示:简体为φ325×8×3380毫米,材质20g,重200公斤,内装U型管状辐射元件,筒体外保温无内衬;原设计条件是:工作压力7kgf/cm~2,工作温度380℃,工作介质分别为空气、蒸汽、半水煤气。由于我们对这台压力容器的设计审查不严,结果在相隔两年的时间里,发生了两次重大
Over the past decade, the small ammonia plant conversion section, the widespread promotion of far-infrared electric heater, I plant is no exception, the application of the fraternal drawings, homemade this equipment. The structural dimensions are shown in the figure below: simplified as φ325 × 8 × 3380 mm, material 20g, weight 200 kg, built-in U-shaped tubular radiating element, tube insulation without lining; the original design conditions are: Working pressure 7kgf / cm ~ 2 , Working temperature 380 ℃, the working medium were air, steam, semi-water gas. As a result of our lax review of the design of this pressure vessel, two major occurrences took place two years later
