摘要： An improved rupture disk assembly and methods and apparatuses for forming a rupture disk are disclosed. The rupture disk assembly includes a rupture disk having a flange connected to a dome-shaped rupturable portion by a transition area. The rupturable portion includes a structural apex formation at or near the apex of the dome and is configured to rupture when exposed to a fluid having a predetermined pressure. Preferably, a safety member is disposed adjacent the rupture disk. The safety member includes a hinge about which the disk bends when the disk ruptures. The present invention is also directed to an apparatus and method for consistently, accurately, and repeatably forming a structural apex formation in a rupture disk before the formation of to the rupture disk dome, during the formation of the rupture disk dome, and after the formation of the rupture disk dome.

摘要： An improved rupture disk assembly for a pressure relief system is disclosed. The rupture disk assembly is sealed between an inlet support member and an outlet support member, each of which define a central fluid pathway. A rupture disk that includes a flange connected to a dome-shaped rupturable portion by a transition area is sealed between the support members. The rupturable portion may include an indentation positioned at the apex of the dome and a score line having a first and a second end. A safety member that has a hinge including a knuckle and a tongue is positioned between the rupture disk and the outlet support member. The knuckle extends downwardly into the dome and extends laterally across the dome to a point that is inside the area circumscribed by the score line or inside the area circumscribed by an arc connecting the two ends of the score line. The rupture disk assembly of the present invention provides a low flow resistance Kr in both gas and liquid applications, a low damage safety ratio, and a high operating capacity.
