APPLICATION 09 · REFINING, PETROCHEMICAL & CHEMICAL PROCESSING

Reactors, columns and separators

Inspection and integrity assessment for critical process equipment exposed to pressure, temperature, aggressive media and process cycling. Within continuous and batch process facilities handling elevated temperatures, pressures and aggressive media, this asset can directly influence loss of containment, ageing mechanisms, shutdown readiness and reliable process performance. A focused integrity programme should therefore connect the design basis, materials, service history, previous findings and current operating condition, so that inspection effort is directed to credible damage locations and produces information that supports practical maintenance decisions.

Integrity Focus

Principal considerations and IAIS UAE support

Principal integrity considerations

  • General or localised corrosion, erosion and service-specific material degradation.
  • Weld, nozzle or attachment cracking associated with fatigue, thermal cycling or stress concentration.
  • Distortion, support deterioration, lining damage and defects at pressure-boundary transitions.

How IAIS UAE may support

  • Establish a damage-mechanism-based plan covering shells, heads, nozzles, welds, attachments, supports and accessible internals.
  • Use visual, ultrasonic, surface and volumetric examination methods selected for material, geometry and expected damage.
  • Characterise reportable indications and provide data for remaining-life, fitness-for-service or repair-engineering review where required.
Outputs & Requirements
