鋼管工作壓力計算器(電腦端網(wǎng)頁版)Pipe Working Pressure Calculation
鋼管的壁厚與壓力計算公式
Equation: P = (2*S*T)/((O.D.-2*T)*SF) 計算公式。
Where:
P = Fluid Pressure (psi) 壓力(單位psi,1MPa = 145psi)
T = Pipe Wall Thickness (in) 厚度 (單位 in,1 in = 25.4mm)
O.D. = Pipe Outside Diameter (in) 外徑(單位 in)
SF = Safety factor (General Calculations 1.5 10, Use 1 For Bursting Pressure) 安全系數(shù)。
S = Material Strength (psi)Ultimate Tensile strength or Yield strength can be used.
Ultimate should be used to determine the bursting pressure.Yield can be used for estimating pressures at which permanent deformation begins. 材料的機(jī)械強(qiáng)度。
相應(yīng)的數(shù)值,轉(zhuǎn)換成對應(yīng)的單位后,填入藍(lán)色部分,點“Calculate!”即可計算出壓力,單位是 Psi, 不要忘記除以145,得出Mpa.
