Cryogenic Breakaway Couplings
Cryogenic Breakaway Couplings (CBC) are used to prevent spillage and damage associated with drive-away or pull-away incidents at terminals and loading or unloading points.
They are suitable for cryogenic liquefied gases, such as LNG, nitrogen, oxygen, argon, and ethylene, down to -196°C. Cryogenic Breakaway Couplings are designed to act as the weakest link in the hose line or loading arm, ensuring efficient operations and minimal downtime.
| Size from: | 1”-8” for breaking pin, 2”-8” for cable release. |
| Material: | Stainless Steel. |
| Seals: | PTFE seals. |
| Working pressure: | 25 bars. |
Poppet design – avoid damaged valves seat or over rotating flip.
Industrial Breakaway will release in any angle from 0-90 degrees.
Industrial Breakaways should always be installed to minimum one fixed point.
Cable release type
In service
The coupling consists of two halves, each with a valve.
Released
After an emergency disconnection the coupling separates and both valves close immediately.
Connections
Benefits
