ABSTRACT:
Apparatus for preventing fragmentation of a rupture disk during pressure relieving rupture and fluid flow through the ruptured disk includes a rupture control assembly for rupturing the disk into a petal having a body and a base for retaining the petal to the rupture disk; protrusions extending from opposite sides of a housing adjacent the rupture disk for retarding motion of generally opposed edges of the petal as the petal is forced away from the ruptured disk and thereby bending the body of the petal into a channel shape; and a protuberance in general alignment with and spaced away from the base of the petal for impacting the channel-shaped body of the petal as the petal is forced away from the rupture disk and converting the kinetic energy of the petal into deformation of the channel-shaped body in order to prevent severance of the base of the petal from the rupture disk.
