Abstract
An improved replaceable carbon rupture disk element and element-holder assembly are provided. The carbon rupture disk element is comprised of a carbon disk having a pair of opposing bores extending thereinto whereby an integral blow-out portion having a particular rupture pressure is formed in the disk connected to an enlarged rim portion. A reinforcing ring is attached to the rim of the carbon disk having a height substantially equal to or greater than the height of the enlarged rim portion of the disk which prevents the rim portion from being subjected to compressive forces which change the rupture pressure of the blow-out portion.
