Thickness of shells under internal pressure for Hemispherical Heads

Hemispherical Head D L t s R o
Hemispherical Head

Values for calculation

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

Calculation

Minimum required thickness of head after forming

$$t=\cfrac{P\cdot L}{2\cdot S\cdot E-0.2\cdot P}$$

$$t_s\geq t$$

Requirements

$$ t < 0.356\cdot L $$ $$ P < 0.665\cdot S\cdot E $$
