Rapid gas decompression (explosive decompression) resistant O-rings for high-pressure gas service.
Explosive decompression (rapid gas decompression, RGD/ED) happens when gas dissolved in an elastomer expands faster than it can diffuse out during depressurisation, blistering and splitting the seal. RGD-resistant compounds are tested and selected specifically to survive that cycle.
Key Features
- Temperature: −40 to 250 °C
- Working pressure: up to 30 MPa
- RGD / explosive decompression resistant
Typical Applications
- High-pressure gas wells and gas-lift systems
- Wellhead and Christmas tree components subject to rapid depressurisation
- Compressor and gas-processing equipment
- Subsea and downhole equipment in HPHT gas service
- Any seal exposed to CO2 or sour gas above roughly 20 bar with fast blowdown
Custom Options & Ordering
- Temperature: −40 to 250 °C
- Working pressure: up to 30 MPa
- RGD / explosive decompression resistant compound
- Available in O-ring, X-ring and custom profiles
