i am working on a case in which a pressure vessel with ammonia and air recently exploded. The bolts attaching the head to the vessel (slotted) just fell off and were not damaged and i am therefore assuming that for some reason the vessel opened up releasing the mixture (6 bar, 900 degrees celsius) culminating in the explosion.
Now my question is why is the design of the vessel such that the bolts are placed in slots rather holes where there is no chance of them falling off as happened?
