Engineering Analysis

Risks & Mitigation
  • Frame deformation under pressure differentials
  • Corrosion in humid environments
  • Improper sealing leading to filter bypass
  • Galvanic corrosion in mixed-material assemblies
FMEA Triads
Trigger: Inadequate material thickness or improper welding
Failure: Frame deformation under operational pressure
Mitigation: Implement finite element analysis during design, use thicker gauge materials for high-pressure applications, and conduct pressure testing during quality control
Trigger: Insufficient surface protection or material incompatibility
Failure: Corrosion leading to structural weakness and contamination
Mitigation: Apply appropriate coatings (powder coating for steel, anodizing for aluminum), use corrosion-resistant materials in humid environments, and implement regular inspection protocols
Trigger: Poor manufacturing tolerances or gasket compression issues
Failure: Air bypass around filter edges reducing filtration efficiency
Mitigation: Maintain tight flatness tolerances (±0.5 mm/m), use compressible gasket materials with proper compression ratios, and implement leak testing during assembly
