Pipe Working Pressure Calculation
Published:2013-06-14 05:37:04    Text Size:【BIG】【MEDIUM】【SMALL

Equation:

P = (2*S*T)/((O.D.-2*T)*SF)

Where:

P = Fluid Pressure (psi) (1MPa = 145psi)

T = Pipe Wall Thickness (in)  (1 in = 25.4mm)

O.D. = Pipe Outside Diameter (in)

SF = Safety factor (General Calculations 1.5 10, Use 1 For Bursting Pressure)

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.
