DESCRIPTION The typical Conventional Bolted Type Rupture Disc Holder is a two-piece unit consisting of a base flange (inlet) and a holddown flange (outlet). The 30 angular seating surfaces of these flanges are machined to grip FikeВs Conventional P/CPV and HO/HOV Series Rupture Discs. When assembled, the crown (bulged portion) of the disc protrudes into the holddown flange and a metal to metal seal is provided. Fikes Bolted Type Rupture Disc Holder can be incorporated into a pressure system by welded or threaded connections bolted between ANSI companion flanges. The Bolted Type Rupture Disc Holder design is based on ANSI B16.5 dimensional standards to provide compatibility with ANSI, JIS, and DIN flanges.ғG Insert type rupture disc holders are furnished with a method of preassembly so the rupture disc may be installed at a workbench or some other convenient location. Once the disc is in place the unit may be assembled and installed into the line, minimizing the chance of damage to the rupture disc.Flexible gaskets are not recommended for use between companion flanges and the ԓG or ԓG Insert holders. However, when the minimum bolt load required to provide an adequate clamping of the disc is maintained and is compatible with the maximum non-flow compression characteristics of the gasket, then flexible gaskets may be used.When welding connections are required consult Fike for the schedule of pipe bore standardly available, or the required schedule of pipe bore must be specified by the customer.To overcome slippage of a rupture disc in a high pressure application, Fike has designed a heavy lip disc and holder combination. Carbon steel and 316 Stainless steel are the standard materials of construction. MonelԮ 400, Inconel 600, Hastelloyή B/C and other materials can be furnished. > HolddownFlange Rupture Disc BaseFlange Figure 1 ORDERING INFORMATION When ordering Conventional Bolted Type Rupture Disc Holder it is necessary to specify the following: Size, ANSI rating, configuration, and material requirements for the inlet and outlet.
