Erosion and erosion-corrosion are mechanical degradation mechanisms enhanced by fluid motion, and typically result in directional or flow-oriented metal loss patterns.
According to API RP 571 Section 5.4.2 (Erosion and Erosion/Corrosion):
“Erosion typically results in localized thinning, often described as grooves, gullies, or horseshoe-shaped patterns... The metal loss is directional and may occur in elbows, tees, reducers, and pumps.”
Hence, Option C (grooves and gullies) most accurately describes erosion and erosion-corrosion characteristics.
