A versatile line of high-performance, corrosion-resistant rupture discs, our composite discs are ideal for systems that require lower burst pressures than standard discs can provide.
Our composite rupture discs consist of two or more metallic or non-metallic components. The components typically consist of a metallic top section and a metallic or non-metallic seal with optional vacuum support, protective rings, gaskets or outlet liner.
This rupture disc features a flat seat design for superior metal-to-metal sealing. If you’re looking for a 30° angular “light lip” seat, ideal for normal operating pressures, try our Standard 30˚ seat rupture disc.
A composite disc for every application
We manufacture several preformed composite rupture discs to fit numerous applications.
The metallic top section can be manufactured from various materials, depending on your application and corrosion-resistance requirements. Seals, protective rings, gaskets and outline liners can also be manufactured from a variety of materials to meet your needs. Contact us or see our preformed composite rupture disc brochure for complete details.
Our unique seven-hole design
Our preformed composite rupture discs feature a seven-hole pattern at the apex of the rupture disc’s top section. This unique configuration, in combination with the pre-cut sections along the dome, provide non-fragmenting characteristics when used with a non-metallic or fluoropolymer seal.
By using this seven-hole design, thicker, more durable materials can be used to manufacture the rupture disc, while still achieving the high 80% operating-to-burst-pressure ratio.
