En wikipedia dan una formula muy sencilla, deberia de todos modos ver las normas ASME u otras para asegurarte que el calculo es correcto.

Spherical vessel

For a sphere, the mass of a pressure vessel is

M = {3 \over 2} P V {\rho \over \sigma}

Where:

M is mass
P is the pressure difference from ambient, i.e. the gauge pressure
V is volume
ρ is the density of the pressure vessel material
σ is the maximum working stress that material can tolerate.
