Abstract
Low pressure, non-fragmenting rupture disks and assemblies including such disks are provided. The rupture disks are each basically comprises of a non-metallic rupture member having one or more lines of weakness formed by indentations therein which define blow-out portions in the rupture member. The blow-out portions are moved outwardly upon rupture of the rupture member along the lines of weakness, but remain attached to the rupture member by non-weakened portions thereof. A non-metallic reinforcing member is attached to the rupture member for preventing tearing of the non-weakened portions of the rupture member.
