← ScienceWhich outcome occurs when dissolved H₂S exceeds solubility in oil pipelines?
A)Hydrogen embrittlement reduces pipeline strength✓
B)Erosion weakens the pipe material
C)Water hammer bursts welds
D)Resonance enhances pipeline vibrations
💡 Explanation
Hydrogen embrittlement develops because hydrogen atoms, produced by H₂S corrosion, diffuse into the steel's lattice structure; therefore weakening it, rather than erosion which is caused by particulate matter and fluid dynamics.
