Abstract
A burst disk assembly relies on a brittle material as the burst disk. Conventional manufacturing tolerances are suitable with the mounting assembly. Flatness and collinearly are achieved by an alignment adapter interfacing between an anvil and the burst disk, on the low-pressure side thereof. A seal, typically thinner than the alignment adapter, is held against the high-pressure side face of the burst disk by a pilot or loader face. All materials are ultra-pure, high-temperature tolerant, and non-reactive. Thin films over metal are not used. Reliable, repeatable, predicable burst pressures have been achieved without resort to highly specialized manufacturing processes. Ceramics and crystalline materials may serve as a burst disk, and quartz has been shown effective. Various grades of fluorocarbon materials have been found to provide suitable coatings, fixtures, and seals. Expanded polytetrafluoroethylene forms a suitable seal. Slightly expanded PTFE such as that sold under the brand-name 'Gylon.TM.' has provided suitable alignment adapters.
