The petroleum and natural gas industry has harsh working conditions including deep underground high pressure, corrosive crude oil and high-temperature gas. Downhole exploration equipment and oil transmission valves need anti-corrosion and pressure-resistant rolling components. Silicon nitride balls are widely used in oil and gas exploitation systems.
Downhole drilling equipment bears high pressure and corrosive crude oil erosion. Sulfur ions and acidic substances in crude oil severely corrode metal parts. Silicon nitride balls resist acid and sulfide corrosion, maintaining stable performance in deep underground harsh environment.
Oil pipeline check valves use silicon nitride balls as sealing cores. High roundness ensures pipeline sealing and prevents oil and gas backflow. High pressure resistance avoids ball deformation caused by pipeline instantaneous pressure impact.
Natural gas purification equipment contains alkaline chemical medium. Metal balls are prone to alkali corrosion and failure. Silicon nitride balls adapt to mixed chemical atmosphere, reducing maintenance frequency of purification equipment.
High-temperature oil well environment tests material thermal stability. Underground oil wells often have high temperature above 100℃. Silicon nitride balls will not soften and deform, ensuring long-term stable operation of downhole bearings.
With the deepening of oil and gas exploitation, the underground working environment becomes more extreme. Silicon nitride balls will replace more metal components and become the mainstream supporting material for energy exploitation equipment.
