Safety comes first, and rupture discs are designed to protect a pressurized vessel or system from overpressurization and potential rupture. Also known as burst discs, pressure safety discs or burst diaphragms, rupture discs are commonly used in the aerospace, defense, petrochemical, pharmaceutical, nuclear and medical industries to protect valuable equipment and keep workforces out of harm’s way. Most rupture discs are made of graphite, and you’ll want to check your required diameter before purchase. You can also shop from a broader selection of pipes, valves and fittings. The non-reclosing action of the rupture disc can also aid in the prevention of potentially damaging vacuum conditions.
