Prediction on the Evacuation Time for Drying of Long-distance Pipeline

    摘要
  • 摘要: 分析了长输管道在无水状态下利用真空设备抽空所需时间的计算方法, 给出了计算公式, 并通过现场试验对其进行了验证。研究结果表明, 在低压力区域, 抽气时间相对较长。

     

    Abstract: The calculation method on evacuation time for drying of long-distance pipeline at the state of water free is analyzed. The calculation equations are given and identified by field test. It is concluded that the evacuation time is relatively long for the low pressure location.
