RGD, or Rapid Gas Decompression, occurs when high-pressure gas trapped in elastomer seals expands violently during sudden system depressurization. This creates internal cracks, blisters, and ultimately seal failure. Common in oilfield valves, risers, and subsea equipment operating above 500 bar. RGD resistance is now mandatory for HPHT (High Pressure High Temperature) sealing applicat... https://globalsealstech.com/oil-gas-seals/
