Materials, Corrosion & Failure Analysis
Material Verification and PMI
Material Verification and PMI is delivered to verify material condition or properties and provide evidence for acceptance, degradation assessment or engineering decisions. IAIS UAE develops the scope around the equipment design, materials, service environment, operating history, expected damage mechanisms and the client’s required decision. This prevents technique-led inspection from becoming disconnected from asset risk and ensures that findings are traceable, technically relevant and suitable for maintenance or engineering review.

Material Verification and PMI
Material Verification and PMI is delivered to verify material condition or properties and provide evidence for acceptance, degradation assessment or engineering decisions.

This prevents technique-led inspection from becoming disconnected from asset risk and ensures that findings are traceable, technically relevant and suitable for maintenance or engineering review.
Category context:
This category investigates what a material is, how it has changed in service, why it has deteriorated or failed and what action can prevent recurrence. Field verification, metallography, chemical analysis, mechanical testing, corrosion evaluation, coating inspection and cathodic-protection assessment provide complementary evidence. The programme is built around a defined technical question and preserves traceability from sampling or field location through testing, interpretation and recommendation.
Integrity Context
Key considerations for this service category
Integrity consideration
Obtaining representative samples or field observations without destroying essential evidence.
Integrity consideration
Reconciling material certificates, PMI results, microstructure, mechanical properties, service conditions and fracture features.
Integrity consideration
Converting laboratory or field findings into practical repair, material-selection, monitoring and operating recommendations.
Category Delivery
How IAIS UAE approaches the work
IAIS UAE may perform or coordinate material verification, PMI, in-situ replication, microstructure review, chemical and mechanical testing, hardness, tensile, impact and bend testing, corrosion evaluation, coating surveys, cathodic-protection assessment and welding qualification support. Failure investigations follow an evidence plan covering background, visual examination, NDT, sampling, laboratory work, causal evaluation and review of credible alternative explanations.
Typical assets
Failed or degraded piping, vessels, welds, fasteners, castings, forgings, structures, coatings, cathodically protected systems, fabricated components and qualification specimens.
Client value
Clients receive evidence-based conclusions that can support immediate containment, repair selection, material substitution, operating changes and prevention of repeat failures. The category also improves procurement and fabrication decisions by verifying material properties and welding-performance requirements before service.
Typical deliverables
Evidence and sample register; PMI/chemistry report; micrographs and metallurgical interpretation; mechanical-test results; corrosion/coating/CP assessment; failure mechanism; root-cause analysis; material or welding qualification records and corrective/preventive recommendations..
Expected outcome
Clear, traceable technical information that supports safety, compliance, reliability, maintenance prioritisation and lifecycle value.
