Thickness criteria of spherical shells in separator (ASME)

Input(s)

P: Pressure (psi)

$\mathrm{R}$: Radius $(\mathrm{ft})$

E: Joint Efficiency (fraction)

S: Maximum Allowable Stress (psi)

Output(s)

$\mathrm{t}$: Thickness of the Spherical Shell (ft)

Formula(s)

$$ \mathrm{t}=\frac{\mathrm{P} * \mathrm{R}}{2 * \mathrm{~S} * \mathrm{E}-0.2 * \mathrm{P}} $$
