许用压力方程
上表中允许压力的计算是根据ANSI/ASME管道规范B31.1公式进行的:
P = 2 SE (t米- a) / (do- 2 y (t米- a)) (1)
在哪里
P =允许压力(psi)
SE =管壁最大允许应力(psi)
t米=壁厚(单位)注意!上述计算采用壁厚-12.5%的制造公差。
A =取决于管道类型的附加厚度(in)(上述计算中A = 0 in)
Y =取决于材料和温度范围的系数(以上计算为Y = 0.4)

a的允许压力4英寸表40管道温度One hundred.oF和许用应力20000 psi可计算为
P = 2 (20000 psi) ((1 - 0.125) (0.237) - (0)) / ((4.5) - 2 (0.4) ((1 - 0.125)(0.237英寸)-(0英寸)))
