Thickness of shells under internal pressure for Cylindrical Shells

Cylindrical_shell
Cylindrical shell

Values for calculation

$E$
$P$ $\mathrm{MPa}$
$R$ $\mathrm{mm}$
$T$ $\mathrm{°C}$
$S$ $\mathrm{MPa}$

Calculation

Minimum required thickness of shell

- Circumferential Stress (Longitudinal Joints)$$t=\cfrac{P\cdot R}{S\cdot E-0.6\cdot P}$$- Longitudinal Stress (Circumferential Joints)$$t=\cfrac{P\cdot R}{2\cdot S\cdot E+0.4\cdot P}$$

Requirements

$$t < 0.5\cdot R$$$$P < 0.385\cdot S\cdot E$$
