| 20100140264 | CONTROLLING THE RATED BURST PRESSURE OF A RUPTURE DISC THROUGH THE USE OF CONTROL SCORES ON THE DISC DOME - 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. | 06-10-2010 |
| 20100140238 | MACHINING SCORE LINES IN A RUPTURE DISC USING LASER MACHINING - A method of forming a score line in a rupture disc using a laser is provided, wherein the method includes selecting a wavelength for the laser that maximizes absorption of the laser radiation by the disc material, selecting a pulse duration for the laser that maximizes a peak power of the laser, selecting a pulse repetition rate for the laser that reduces a heat affected zone of the rupture disc during ablation, and selecting the speed of relative motion between the laser and the rupture disc. The score line is ablated in the rupture disc using the laser to remove material from the rupture disc as vapor without melting or oxidizing disc material adjacent the material being removed. | 06-10-2010 |
