新钢公司燃一氧枪工程中的氧气管道（管径108mm,长70mm,压力2.0MPa）施工完毕后,按冶金部《氧气安全规程》及设计要求,管道须经8h无油空气吹扫清除管内铁锈及杂质后方可投入使用。但新管连接在铁合金富氧干管上,如按常规做法,即启动氧气站氧压机抽取无油空气吹扫,则三钢厂炼钢炉及铁合金富氧站都得停产,造成经济损失。 笔者认为利用瞬间释放瓶装无油压缩空气的能量——爆破法,可吹扫清除管内杂物。
After completion of the construction, according to “Oxygen Safety Regulations” and design requirements of the Metallurgical Department, the pipeline shall be purged with oil-free air for 8 hours after being cleaned by the oxygen pipeline of Oxygen Lance Project (diameter 108mm, length 70mm, pressure 2.0MPa) Pipe rust and impurities before they can be put into use. However, the new pipe connected to the iron-rich oxygen-rich dry pipe, as usual practice, that is, start the oxygen station oxygen compressor oil-free air purge, then the three steelmaking furnace and iron alloy oxygen station have to stop production, resulting in economic losses . I believe that the use of instant release of bottled oil-free compressed air energy - blasting method can purge purge tube debris.
