运行中天然气管道输气公式的研究

Research on the Formula for Gas Transmission Pipelines in Operation

利用两条运行管道(一条输送净化气,一条输送原料气)的实测值,分析拟合出其水力摩阻系数计算公式,从而得到了适合这两条管道的输气公式。该公式不仅适合于实测值用于拟合公式的那个月份的有关计算,而且能够应用于其它月份的水力计算。

Based on the measured values of two operating transmission lines (one for purified gas , the other for raw gas),the formulae for calculating their hydraulic friction coefficients are analysed, fitting is made, and their gas transmission formula is derived. This formula is not only applicable to the calculation in the month when measured values are used to fit the formula, but also to the hydraulic calculations in other months.
