The typical Conventional Bolted Type Rupture Disc Holder is a two-piece unit consisting of a base flange (inlet) and a hold-down flange (outlet). The 30° angular seating surfaces of these flanges are machined to grip Fike’s Conventional P/CPV and HO/HOV Series Rupture Discs. When assembled, the crown (bulged portion) of the disc protrudes into the hold-down flange and a metal to metal seal is provided.
