APPLICATION 30 · WATER, WASTEWATER & DESALINATION

Evaporators, condensers and heat exchangers

Inspection of tubes and pressure components affected by scaling, erosion, corrosion, leakage and thermal cycling. Within water production, treatment, transmission and discharge infrastructure exposed to saline and chemically aggressive service, this asset can directly influence leak prevention, corrosion management, structural condition and dependable public or industrial service. 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

  • 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 AWWA, ASME B31 series, API tank standards where applicable, ISO, ASTM, EN, BS and authority/client requirements. Final references and acceptance criteria remain subject to approved project and statutory requirements.
