📌 Food Processing Mounting Rail - Uniform corrosion in mixed-flowing gas exposure

Industry: Food Processing · Severity: Critical · Mechanism: Uniform corrosion · Risk: 90/100

🧾 Summary

A mounting rail used in a food processing application shows uniform corrosion risk after exposure to mixed-flowing gas exposure. The design review focuses on material pairing, geometry, coating coverage, inspection access, and realistic validation testing.

⚠️ Design Risk

Likely weak points include local electrolyte retention, incompatible material pairing, coating discontinuities, trapped debris, and missing acceptance criteria for corrosion validation.

🛠️ Recommended Controls

Recommended controls: lubricant/contact finish change, sacrificial element review, and edge-radius update. Add drawing notes, supplier evidence requirements, and a validation plan that reflects the expected service environment.

🎓 Learning Notes

Learners should identify the corrosion mechanism, estimate severity, and decide whether prevention should come from material change, coating change, geometry change, sealing, isolation, or inspection planning.
