压力管道事故处理 | 2012-8-13 7:37:00
- 上一篇:烟花爆竹生产的安全保护设施与装置
- 下一篇:柴油锤桩机安全操作技术
什么叫压力管道?
“压力管道”在《压力管道安全管理与监察规定》第二条中将压力管道定义为:“在生产、生活中使用的可能引起燃爆或中毒等危险性较大的特种设备”。
在国务院2009年5月1日颁发实施的《特种设备安全监察条例》(国务院令第549号)中,将压力管道进一步明确为“利用一定的压力,用于输送气体或者液体的管状设备,其范围规定为最高工作压力大于或者等于0.1MPa(表压)的气体、液化气体、蒸汽介质或者可燃、易爆、有毒、有腐蚀性、最高工作温度高于或者等于标准沸点的液体介质,且公称直径大于25mm的管道”。这就是说,现在所说的“压力管道”,不但是指其管内或管外承受压力,而且其内部输送的介质是“气体、液化气体和蒸汽”或“可能引起燃爆、中毒或腐蚀的液体”物质。
从广义上理解,压力管道是指所有承受内压或外压的管道,无论其管内介质如何。压力管道是管道中的一部分,管道是用以输送、分配、混合、分离、排放、计量、控制和制止流体流动的,由管子、管件、法兰、螺栓连接、垫片、阀门、其他组成件或受压部件和支承件组成的装配总成。
