Abstract:
A reverse-acting rupture disc (10) having a laser-defined reversal initiation feature (16) is provided in the bulged section (12) of the disc. The reversal initiation feature comprises at least a first lased area (22) that has a reduced thickness relative to rest of the bulged section. A second lased area (24) may also be provided within the margins of the first lased area. The second lased area has a depth that is greater than the depth of the first lased area. A line of weakness (40) may be formed in the bulged section that functions to direct reversal of the bulged section toward a particular area of the disc.
