Abstract

A burst disk assembly has a burst disk which is interposed within the high pressure relief vent of a superconducting magnet. The burst disk is a composite design constructed of a solid carbon graphite center surrounded by an integrally formed stainless steel ring. A captured burst disk flange insures proper placement and seating of the burst disk during replacement and supports the burst disk so as to prevent it from falling or dropping out of the assembly during replacement of the ruptured burst disk. A deformable gasket contiguous to the burst disk seals the burst disk to the captured burst disk flange when the disk and the flange are pressed together. Attachment bolts are used to provide even application of pressure along the face of the burst disk and the captured burst disk flange.
