压力容器广泛用于化工制药行业 ,它是化学药物合成过程的主要生产设备。其工作介质大都具有易燃易爆、有毒和腐蚀性强的特点 ,而且 ,工艺参数范围也较大 ,工作条件极为复杂 ,一旦发生事故 ,危害极大。因此 ,必须认真贯彻执行《压力容器安全技术监察规程》（以下简称《容规》） Pressure vessels are widely used in the chemical industry, which is the main production facility for chemical synthesis. Most of its working medium with flammable, toxic and corrosive characteristics, but also a larger range of process parameters, the working conditions are extremely complex, in the event of an accident, endangering great. Therefore, we must conscientiously implement the “Pressure Vessel Safety Technology Supervision Regulations” (hereinafter referred to as “compliance”)
