The Lamé equation is used for the calculation of internal yield pressure and burst pressure.
Internal yield pressure is calculated by using the following formula:
IYP = Internal yield pressure (psi)
Ys = Yield strength (psi)
OD = Nominal outside diameter (in)
Wt = Minimum wall thickness (in)
The burst pressure is calculated by using the following formula:
BP = Burst pressure (psi)
Ts = Tensile strength (psi)
OD = Nominal outside diameter (in)
Wt = Minimum wall thickness (in)
