Safety Vent (CID)
View system integration details
Based on aggregated insights from structured factory profiles within the CNFX directory, the standard Rupture Disc used in the Chemical Manufacturing sector typically supports operational capacities ranging from standard industrial configurations to heavy-duty production requirements.
A canonical Rupture Disc is characterized by the integration of Disc Membrane and Holder/Flange Assembly. In industrial production environments, manufacturers listed on CNFX commonly emphasize Metal (e.g., Stainless Steel, Inconel, Hastelloy) construction to support stable, high-cycle operation across diverse manufacturing scenarios.
A non-reclosing pressure relief device designed to burst at a predetermined pressure to protect equipment from overpressure.
Technical details and manufacturing context for Rupture Disc
Commonly used trade names and technical identifiers for Rupture Disc.
This component is essential for the following industrial systems and equipment:
| pressure: | Typically 0.1 to 10,000 psig burst pressure range |
| flow rate: | Not applicable - instantaneous full opening upon burst |
| temperature: | -200°C to +400°C (depending on material) |
| slurry concentration: | Not recommended for high solids (>5%) without special design |

For corrosive chemical applications, Hastelloy and graphite rupture discs offer excellent corrosion resistance. Inconel is preferred for high-temperature corrosive environments, while composite materials provide chemical compatibility for specific aggressive media.
Burst pressure should be set 10-25% above normal operating pressure but below the maximum allowable working pressure (MAWP) of protected equipment. Consider factors like pressure spikes, temperature effects on material strength, and process media compatibility when specifying.
Rupture discs require regular inspection for corrosion, fatigue, or damage. Replace discs after activation or according to manufacturer recommendations. Ensure proper installation torque on holder/flange assemblies and verify gasket integrity during maintenance cycles.
