Thickness from Pressure
t = ( P × D ) / ( 2 × (S×E + P×Y) ) + ctmin = t / (1 - mill_tol)
// Reverse (MAWP from thickness)
P = 2SE(t-c) / (D - 2Y(t-c))
Variables
t = req. thickness (mm) | P = pressure (MPa)D = outside diameter (mm) | S = allow. stress (MPa)
E = quality factor | Y = temp. coeff. | c = corrosion (mm)
