A stacked rupture disk assembly of the present invention is adapted to be positioned between flanges in a vent pipe or pressure relief port of a pressure vessel. The stacked rupture disk assembly includes a first rupture disk assembly and a second rupture disk assembly mechanically affixed to the first rupture disk assembly. Each rupture disk assembly includes a graphite rupture disk defining an annular support portion surrounding an thinner rupture membrane adjacent and flush with a first end of the annular support portion. The annular support portion and the rupture membrane define a substantially planar outer surface of the rupture disk. The annular support includes a recessed region extending from an opening in a second end of the annular support to the rupture membrane. Optionally, the second rupture disk assembly includes a support member having spaced apart first and second ends and adapted to be inserted into the recessed region such that the first end abuts and supports the rupture membrane. The support member is configured to permit fluid communication between the second side of the annular support portion and the rupture member. The first and second rupture disk assemblies are positioned in stacked alignment such that the second sides of the annular support portions are adjacent and the first sides of the annular support portions face outwardly. The stacked rupture disk assembly is oriented within the vent pipe flanges in a stacked configuration such that the planar side of the first rupture disk faces the pressure vessel and the planar side of the second rupture disk faces a vent side or a side away from the pressure vessel.
