Rupture disk construction |
May 2, 1995 |
| A rupture disk provides an improved scoring configuration that allows low pressure burst disks of very small diameter such as, for example, 0.25 inches in diameter, wherein the score of the rupture disk is generally circular in shape which terminates at end portions that define a hinge |
