AI Technical Summary
Conventional FS-Seals fail to maintain sealing integrity under the stringent conditions mandated by the API 6A PR2F standard, particularly due to vulnerabilities from the concavity at the outer diameter leading to Rapid Gas Decompression (RGD) and extrusion under extreme pressure and temperature variations.
A seal with an optimized profile featuring a radially inwardly extending trapezoidal projection on the inner surface, combined with reinforcement members, enhances sealing performance by distributing load uniformly and resisting extrusion, suitable for pressures up to 15,000 psi and temperatures from 0°F to 300°F.
The optimized seal design maintains sealing integrity and structural rigidity, preventing fluid leakage and deformation, ensuring compliance with API 6A PR2F standards by enhancing mechanical stability and resistance to pressure fluctuations.
