Dual Rupture Disk Sub
The dual rupture disk sub is a bidirectional isolation tool with opposing ceramic disks rated to 10,000 psi. It provides bidirectional pressure containment and allows full‑bore flow once the disks are mechanically ruptured by a drop bar or other intervention. Typically used during well completions and wellbore displacement.
Specifications
| Size range | 2.375″ – 2.875″ |
Key Features
- Provides temporary bidirectional isolation during completion or displacement operations.
- Rated to 10,000 psi above and below the disks.
- Dual ceramic disks ensure pressure integrity under differential pressures.
- Disks can be mechanically ruptured by drop bar or intervention to open the string.
- Allows full‑bore flow once the disks are ruptured.
- Available in box‑by‑pin or box‑by‑muleshoe/re‑entry guide options.
