Rupture Disks A rupture disk is a device designed to function by the bursting of a pressure-retaining disk (Fig. 26-15). This assembly consists of a thin, circular membrane usually made of metal, plastic, or graphite that is firmly clamped in a disk holder. When the process reaches the bursting pressure of the disk, the disk ruptures and releases the pressure. Rupture disks can be installed alone or in combination with other types of devices. Once blown, rupture disks do not reseat thus, the entire contents of the upstream process equipment will be vented. Rupture disks are commonly used in series (upstream) with a relief valve to prevent corrosive fluids from contacting the metal parts of the valve. In addition, this combination is a reclosing system. [Pg.2290]

In general, companies in the plastics industry can obtain patents upon the processes they use to manufacture new materials (Chapter 4, DESIGNING AND LEGAL MATTER). However, since a processed patent discloses a great deal of information that may be useful to competitors even though they are not using or do not wish to use the exact process as that described in the patent. Some firms in the industry do not... [Pg.577]
