Steam and feedwater piping

Integrity assessment of high-energy and utility piping, including welds, bends, supports and critical stress locations. Within thermal and conventional power assets operating under cyclic, high-temperature and high-pressure duty, this asset can directly influence availability, pressure-part reliability, outage optimisation and safe long-term operation. 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

  • Internal and external corrosion, localised pitting, erosion or flow-assisted wall loss.
  • Weld or heat-affected-zone cracking, fatigue at branches and vibration-sensitive locations.
  • Coating or insulation breakdown, support deterioration, displacement and mechanical damage.

How IAIS UAE may support

  • Review line class, design and operating history to establish damage mechanisms and critical inspection locations.
  • Combine visual examination, thickness mapping, weld NDT, corrosion screening and specialised access as justified by the scope.
  • Evaluate indications, establish condition trends and support repair, monitoring or engineering-assessment decisions.
Outputs & Requirements

Typical outputs and applicable standards

Typical outputs

Inspection plan, traceable location register, calibrated readings and images, indication assessment, marked-up drawings and prioritised recommendations.

Codes & standards

The activity may be planned and reported against the applicable provisions of ASME BPVC Sections I, V, VIII and IX, ASME B31.1, API 579-1/ASME FFS-1, ASTM, ISO and owner requirements. Final references and acceptance criteria remain subject to approved project and statutory requirements.
