APPLICATION 11 · REFINING, PETROCHEMICAL & CHEMICAL PROCESSING

Heat exchangers, condensers and air coolers

Tube and component assessment to identify wall loss, leakage, fouling-related damage and service-induced deterioration. 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.

Heat exchangers, condensers and air coolers

Tube and component assessment to identify wall loss, leakage, fouling-related damage and service-induced deterioration.

Integrity Focus

Principal considerations and IAIS UAE support

Principal integrity considerations

  • Tube-wall loss, pitting, erosion, fretting and inlet-end attack.
  • Tube-to-tubesheet or pressure-boundary leakage, cracking and joint deterioration.
  • Fouling, deposits, thermal cycling and support damage that can reduce heat-transfer performance.

How IAIS UAE may support

  • Select tube and component techniques according to material, geometry, cleanliness, access and expected defect morphology.
  • Screen the bundle and pressure boundary, then target suspect areas for confirmation and dimensional assessment.
  • Rank affected tubes or components and provide repair, plugging, replacement or monitoring inputs.
Outputs & Requirements

Typical outputs and applicable standards

Typical outputs

Tube condition maps, signal and indication summaries, component NDT records, defect distribution, comparison data and recommendations.

Codes & standards

The activity may be planned and reported against the applicable provisions of API 510, API 570, API 571, API 579-1/ASME FFS-1, API 580/581, ASME BPVC, ASME B31.3, ASTM, ISO and client requirements. Final references and acceptance criteria remain subject to approved project and statutory requirements.
