Composite rupture disc with narrower operating ratio.

The Composite Rupture Disc for an insert holder has a 30° or Flat Seat configuration and consists of two or
more metallic or non-metallic components. The components typically consist of a metallic top section and metallic or non-metallic seal, with an option vacuum support, protective rings, gaskets or outlet liner.
The Composite Rupture Disc top section is manufactured with a patented seven hole pattern, and with six pre-cut sections providing a non-fragmenting design when used with a non-metallic or Teflon® seal.
