Failure Analysis
Field Failure Cases
Real incidents. Anonymized. Documented to help engineers avoid the same mistakes.
Pressure Vessel
Creep Damage in High-Temperature Service
Impact
Unplanned shutdown
Root Cause
Inadequate monitoring of operating hours above design temperature
Key Lesson
Time-temperature logging is non-negotiable for creep-susceptible materials
Storage Tank
Floor Plate Perforation from MIC
Impact
Product loss + environmental incident
Root Cause
Stagnant water under floor insulation created microbiologically influenced corrosion
Key Lesson
Tank bottom inspection intervals must account for insulation condition
Piping
Injection Point Erosion-Corrosion
Impact
Process upset + 3-day repair
Root Cause
Chemical injection velocity exceeded material limits
Key Lesson
Injection quill design is as critical as the chemical selection
