[PSUBS-MAILIST] Dome test chamber

[hank pronk via Personal_Submersibles]

 Alan, there is no pressure inside.  The pressure is contained between the outside of the dome and the inside of the pressure chamber.Hank

 Hank,the internal pressure on the hatch dogs would need consideration.There would be a lot of pressure over the area of the hatch.How did you deal with that?Alan

 Thanks guys, it makes me think this should be a design consideration when building a sub, especially a sub with flat ports.  All you would do is increase the size of bolts on the retaining ring, or if that is not practical then increase the number of bolts.  You could do an annual pressure test of each port without removing the port and test on its actual seat.  Hank
