Oil & Gas / LNG Sealing Solutions
High-Integrity Sealing Systems for Extreme Pressure, Cryogenic Conditions, and Corrosive Media
Overview
 |
Oil and gas operations are among the most demanding environments for sealing systems, involving extreme pressures, aggressive chemicals, wide temperature ranges, and long continuous operating cycles. |
Across upstream, midstream, and downstream applications, seals are essential for maintaining system integrity in drilling equipment, wellheads, pipelines, compressors, and refining systems. LNG applications add further complexity due to cryogenic temperatures that can significantly affect material performance.
Failure of sealing systems can lead to leakage, safety hazards, environmental impact, and costly downtime. Tesel Seal develops high-integrity sealing solutions engineered for reliability, safety, and long-term performance in critical oil & gas and LNG environments.
Operating Conditions and Engineering Parameters
High Pressure Conditions
Oil and gas systems often operate above 70 MPa with frequent pressure fluctuations. Seals must resist extrusion, deformation, and fatigue under both steady and dynamic loads.
Extreme Temperature Range
Applications span from cryogenic LNG conditions (down to -196°C) to high-temperature refining environments above +250°C. Materials must remain stable across this wide range.
Chemical Exposure
Seals are exposed to hydrocarbons, H₂S, CO₂, water, and chemical additives. Resistance to swelling, degradation, and chemical attack is essential.
Mechanical Stress
Vibration, thermal cycling, and continuous operation place long-term stress on sealing systems, requiring high durability and fatigue resistance.
Key Challenges in Oil & Gas and LNG Sealing
High Pressure and Cycling
Pressure fluctuations can cause extrusion and edge damage. Anti-extrusion designs are critical for reliability.
Cryogenic Conditions
At ultra-low temperatures, materials may become brittle and lose elasticity, increasing leakage risk due to thermal contraction.
Chemical and Corrosion Resistance
Exposure to sour gas and hydrocarbons can degrade materials over time, requiring careful material selection.
Gas Leakage and Permeation
Gas sealing requires minimizing permeation and maintaining tight sealing under varying conditions.
Thermal Cycling and Fatigue
Repeated temperature and pressure changes can lead to long-term material fatigue and performance loss.
