Oil & Gas Sealing Solutions Sealing Performance & Engineering
Upstream exploration, subsea completions, high-pressure pipeline valves, and downstream refining impose harsh chemical and thermodynamic stresses on elastomeric seals. Failure in hydrocarbon containment results in hazardous blowouts, costly flaring, and environmental contamination.
Operating Challenges
- Rapid Gas Decompression (RGD / AED): High pressure gases permeate the elastomer matrix; when system pressure drops rapidly, gas expands inside the polymer causing micro-fracturing and internal blisters.
- Sour Gas (H2S) & Amine Corrosion: Hydrogen sulfide and amine corrosion inhibitors chemically attack standard elastomer backbones, leading to severe embrittlement.
- Subsea & Downhole Temperatures: Equipment must maintain positive sealing from freezing subsea conditions (-20°C) up to downhole wellbore temperatures (+200°C).
Engineered Solutions
