(1）管道铁锈及其他固体微粒随气体高速流动产生摩擦热和碰撞热,是管道发生爆炸的一个因素。 （2）由于漏气,在管道外围形成爆炸性气体停滞的空间,遇明火即发生燃烧爆炸。 （3）外部明火导入管道内部。这里包括管道附近明火的导入,由于明火导入管内造成燃爆。 （4）管道过分靠近热源,管内气体过热引起燃烧爆炸。 （5）氧气管道阀门粘有油脂。 (1) Pipeline rust and other solid particles with high-speed gas flow friction heat and heat of collision, is a factor in pipeline explosion. (2) due to leakage, the formation of explosive gas in the periphery of the pipeline stagnation of the room, in case of fire that is burning explosion. (3) external fire into the pipeline interior. Here includes the introduction of open flame near the pipe, due to open flame caused by fire into the tube explosion. (4) pipe is too close to the heat source, the tube overheating caused by gas explosion. (5) Oxygen pipeline valve with grease.
