Abstract
A pressure vessel is provided having a wall with an inner surface defining a chamber about an axis and an outer surface. The wall has a thickness with at least one vent hole therein located substantially parallel with the axis. The at least one hole is located a distance from the axis, the distance providing an outer thickness of the wall between the at least one hole and the outer surface sufficient to withstand a stress generated by pressure within the pressure vessel. An inner thickness of the wall between the at least one hole and the inner surface to permit a crack to propagate from the inner surface and connect with the hole causing venting of the pressure in the chamber.

A pressure vessel having a wall with an inner surface defining a chamber about an axis and an outer surface, said wall having a thickness with at least one vent hole therein located substantially parallel with said axis;
- said at least one hole being located a distance from said axis, said distance providing an outer thickness of said wall between said at least one hole and said outer surface sufficient to withstand a stress generated by pressure within said pressure vessel;
- and
- an inner thickness of said wall between said at least one hole and said inner surface to permit a crack to propagate from said inner surface and connect with said hole causing venting of said pressure in said chamber.
A cylindrical pressure vessel having a wall with an inner cylindrical surface having a diameter (DI) defining a chamber about a longitudinal axis and an outer cylindrical surface having a diameter (Do), said wall having a thickness with at least one vent hole therein located substantially parallel with said axis;
- said at least one hole being located along a cylindrical region in said thickness, said cylindrical region being concentric with said longitudinal axis and having a diameter (Dv) to provide an outer thickness of said wall between said at least one hole and said outer surface sufficient to withstand a stress generated by a pressure (p) within said pressure vessel;
- and
- an inner thickness of said wall between said at least one hole and said inner surface to permit a crack to propagate from said inner surface and connect with said hole causing venting of said pressure in said chamber.
