Saf-T-Change™ QDR™(Quick Disk Replacement) US and International patents pending |
This innovative solution ensures minimal downtime to change out a rupture disk. After activation, the replacement disk is quickly slid into place. BS&B encounters situtions where processing plants take great financial hits in lost production due to blown rupture disks. If several hours are required to replace the disk, it does not take long for the the Saf-T-Change to pay for itself many times over. Contact BS&B today for more information.
Features
- Sizes 1/2” (12mm) through 44” (1120mm) sizes available.
- ANSI, DIN, and JIS flange configurations.
- For use with liquid, vapor, steam, two-phase, and multiphase process media.
- Wide range of materials (carbon steel, stainless steel, alloy 400, alloy 600, Alloy C-276, and others).
- For use with forward acting (tension loaded) and reverse buckling (compression loaded) rupture disks.
- Operating pressures up to 95% of marked burst pressure (100% of minimum burst pressure).
- Protective cover provided for rupture disk device in standby.
- Manual and actuated models available.
- Self locking.
- No moving parts in the process flow path.
- Design pressures up to 6100 psig (420 barg).
- Temperature range of -155°F (-104°C) to 1200°F (650°C).
- Elastomer o-ring and graphite seals available.
- Leak tight, 100% leak tested to maximum operating pressure of each disk model.
Benefits
- Speed and efficiency. In small line sizes, rupture disks can be changed in less than 10 seconds.
- Downtime is reduced dramatically.
- Personnel and environmental exposure to process media is minimized.
- Only one operator is required to change a rupture disk, even in large line sizes.
- No tools, cranes, or other logistical considerations for larger sizes or difficult to access installations.
- No internal seals in process flow path.
- Pre-torqued safety heads with bite type seal ensure optimal leak tightness and performance.
- Each device is designed to the specific application where it will be utilized.
- Horizontal or vertical installation.
- Allows for inspection of rupture disks with minimal downtime.
