I am intending to construct a small pressure vessel. It needs to be around 7 centimeters in length and width and around 1-2 centimeters in depth. It must be capable of being pressurised to 300 psi with sufficient space to contain a small amount of liquid (say 5cc)
The body of the vessel must be made out of nickel-plated annealed brass.
The vessel will have a brass cap, held in place with silver solder.
The cap must be sufficiently thin to be pierced when it is inserted into a receptacle.
Is this design feasible?
