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) 安全係數。
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. 材料的機械強度。
不管是不鏽鋼管還是碳鋼管還是焊接鋼管其壓力計算方法都是一樣的,有公式如下:
P = (2*S*T)/((O.D.-2*T)*SF)
計算公式。
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) 安全係數。
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. 材料的機械強度。
網上頁也有線上的計算器,
鋼管工作壓力計算器(無縫鋼管內部壓力計算器)鋼管壓力線上計算器開啟這個網頁,把你要求壓力的鋼管的相關尺寸引數填入 就可以計算出這個鋼管能承受的壓力和爆破的壓力,請參考。
