根据液氧、气氧管道并网输送的特点,对供氧工序、管道结构进行技术改造,使输送的氧气中少含水分,保证冬季氧气输送管路不冻堵。 According to the characteristics of liquid oxygen and gas-oxygen pipelines connected to the grid, the oxygen supply process and the pipe structure are reformed to make the oxygen contained in the pipe less water-containing so as to ensure that the winter oxygen transmission pipelines are not frozen and blocked.
