Fike’s "GI" insert rupture disc holder consists of a base (inlet) and a holddown flange (outlet). "GI" holders fit between most standard companion flanges within ANSI, JIS, DIN, and ISO bolt circle configurations.
Additionally, 300 series stainless steel sideclips are provided for preassembly so that the rupture disc may be installed at a workbench or some other convenient location.
Once the disc is in place the assembly may then be installed into the line, minimizing the chance of damage to the rupture disc.
