APPLICATION 75 · MINING, METALS, MINERALS & CEMENT

Kilns, furnaces and refractory-lined equipment

Integrity support for shells, welds, supports and heat-affected components operating under sustained thermal conditions. Within heavy-process facilities exposed to abrasion, impact, vibration, heat and high production loads, this asset can directly influence wear management, fatigue control, structural reliability and maintenance productivity. 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

  • Overheating, oxidation, creep, thermal fatigue and high-temperature corrosion.
  • Tube or coil thinning, cracking, bulging, distortion and support-related damage.
  • Refractory or insulation deterioration, flame or flow impingement and temperature-driven material change.

How IAIS UAE may support

  • Use operating history and known temperature zones to focus inspection on susceptible pressure parts and structural components.
  • Combine visual assessment, thickness measurement, surface/volumetric NDT, dimensional checks and materials evaluation as appropriate.
  • Document active damage, compare deterioration trends and support outage repair or continued-operation decisions.
Outputs & Requirements

Typical outputs and applicable standards

Typical outputs

High-temperature asset condition report, tube or component maps, NDT results, damage ranking, repair priorities and monitoring guidance.

Codes & standards

The activity may be planned and reported against the applicable provisions of applicable ASME, AWS, ISO, ASTM, EN, BS, OEM criteria and site engineering requirements. Final references and acceptance criteria remain subject to approved project and statutory requirements.
