A mechanical inspector should be familiar with certain types of failure mechanisms, whereas he can describe what he saw to the engineer. Too often any wastage of metal is called corrosion, and that is not always the case. Erosion exhibits itself by a smooth profile and is the loss of cross-sectional thickness by a wearing away process. Corrosion is a chemical attack due to a reaction with the base metal and the chemical it sees. These are different examples of cross-sectional loss.
R4-1: Erosion of a pump casing due to bauxite slurry
R4-2: Stress Corrosion Cracking
R4-3: 1.5″ X 1.5″ X 1.5″ Corroded socket weld tee with improper clearance between end of pipe to fitting hub on the I.D.
R4-4: Internal Corrosion of longitudinal weld seam
R4-5: Intergranular Corrosion Specimen
R4-6: Corrosion on the internal surface of a vessel
R4-7: Corrosion with a through hole on a socket weld 90° elbow
R4-8: Internal erosion on a API-6A flange at the exit point of a wellhead
R4-9: Toe crack due to hydrogen cracking on weld to a API-6A flange & concentric reducer
R4-10: Toe crack on Natural gas underground line-appears to be environmental corrosion
