APPLICATION 53 · MANUFACTURING, FABRICATION & OEM

Heat exchangers and tube bundles

Manufacturing inspection of shells, tubes, tube-to-tubesheet joints, welds and completed assemblies before delivery. Within workshop and vendor manufacturing activities from material receipt through final release, this asset can directly influence conformity, traceability, fabrication quality and complete manufacturing records. 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.

Application & Asset Overview

Heat exchangers and tube bundles

Manufacturing inspection of shells, tubes, tube-to-tubesheet joints, welds and completed assemblies before delivery. Within workshop and vendor manufacturing activities from material receipt through final release, this asset can directly influence conformity, traceability, fabrication quality and complete manufacturing records. 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 ASME BPVC Sections V, VIII and IX, ASME B31.3, AWS D1.1, ISO 3834, ISO 9712, ASTM and approved purchase specifications. Final references and acceptance criteria remain subject to approved project and statutory requirements.
