Rupture Disc — Precision Burst Safety Device
Ultra high pressure tempered glass rupture disc for precise overpressure protection. Batch-tested burst performance, ASME-aligned selection guidance and high-pressure options up to extreme ranges.
Description
Rupture discs engineered for ultra-high pressure applications. They deliver predictable burst behavior, controlled opening characteristics, and traceable burst testing. For example, these discs suit high-pressure labs, oilwell cementing, specialty reactors and other extreme-pressure systems. Before selecting one, please review pulsation, impact loading, cycling and media compatibility with your application engineer.
Product at a glance
- Burst range: Customizable — we offer setpoints from low pressure up to ultra-high ranges. In particular, specialized models exist that are rated from hundreds to thousands of bar.
- Material: Tempered or chemically strengthened glass, or glass-composite elements; you can add metal backing or composite assemblies to control fragments.
- Repeatable & verifiable: Our factory performs burst tests and issues a burst certificate that shows the test curve and batch traceability.
- Application fit: Designed for high-pressure laboratory rigs, oil & gas downhole cementing and stimulation, high-pressure reactors and aerospace test benches.
- Standards & compliance: We size and specify per ASME and industry rupture disc guidance (ASME/API). Also, we provide installation torque and seat selection guidance.
Why choose a tempered glass rupture disc?
- Predictable fracture mechanics: We engineer glass elements to fracture in a controlled pattern. When paired with the correct backing and containment, they produce low fragment dispersion.
- Contamination control: Because glass does not shed metal debris, glass-based burst elements reduce metallic contamination risk in sensitive chemical, pharmaceutical or optical processes.
- Visual verification: You can visually confirm fracture. Moreover, certain designs serve as an optical inspection window until the moment of burst.
Important: Tempered glass rupture discs represent a specialized solution. Therefore, confirm pulsation, impact loading, cycling and media compatibility with your application engineers before selection.
