Abstract
A rupture disc for use in a pressure relief system includes a dome having a concave and a convex side and a circumferential flange associated therewith. At least one control score is formed or otherwise produced in the dome at a radial position between an apex of the dome and an outer circumference of the dome. At least one of a depth, a width, a length and the radial portion of the at least one control score is selectively controlled so that the depth, width, length, and/or radial position of the at least one control score controls the pressure at which the dome will start to collapse.
Claims45
A reverse-acting rupture disc for use with and attached to a storage and/or pressurized system comprising:
- a dome having a convex side, a concave side, and a thickness;
- at least one control score formed in said dome between an apex of said dome and an outer circumference of said dome and having a reduced thickness as compared to the thickness of said dome, said at least one control score having a length, a width, a depth and a radial position between the apex of said dome and an outer circumference of said dome;
- and
- a rupture score formed in said disc, said disc being configured to rupture at said rupture score after said dome collapses;
- the radial position of said at least one control score being selectively determined to weaken said dome and to reduce a reversal pressure of said dome so as to control the reversal pressure at which said dome will start to collapse, said at least one control score being radially positioned on said dome between the apex and said rupture score.

- the radial position, the length, the width, and the depth of said at least one control score being selectively determined to weaken said dome and to reduce a reversal pressure of said dome so as to control the reversal pressure at which said dome will start to collapse, said at least one control score being positioned on said dome between the apex and said rupture score.
(canceled)
A method of manufacturing a reverse-acting rupture disc for use with and attached to a storage and/or pressurized system, said method comprising:
- providing a disc having a dome including a concave side, a convex side, and a thickness;
- forming at least one control score in the concave side of the dome between an apex of said dome and an outer circumference of said dome having a reduced thickness as compared to the thickness of said dome, said at least one control score having a length, a width, and a depth;
- forming a rupture score in said disc, said disc being configured to rupture at the rupture score after said dome collapses;
- and
- positioning the at least one control score at a radial position between an apex of the dome and an outer diameter of the dome to weaken said dome and to reduce a reversal pressure of said dome so as to control a reversal pressure at which the dome will start to collapse,
- said at least one control score being positioned on said dome between the apex and said rupture score.
