Positive Material Identification (PMI) Alloy Verification (AV)

Positive Material Identification (PMI) Alloy Verification (AV)

INDEi technician carrying out positive material identification (PMI) of valve bodiesWith engineering placing increasing demands on material performance and material design being pushed to the limit, the need to ensure that the correct material specifications are being used has become even more essential.

Portable positive material identification (PMI) is an indispensable tool in modern fabrication and safety analysis and provides the safeguard for allowing the crosschecking of material and providing the alloy composition at the point of manufacture without the need to rely on the mill certification or material specification.  Positive material identification (PMI) / Alloy verification (AV) ensures that the right metal is used in process systems where corrosive conditions, high temperatures and pressures meet. 

Without Positive Material Identification (PMI) the errors created in using incorrect material could result in costly rectification or at worse product failure during service with possible catastrophic results.

Our Positive Material Identification (PMI) / Alloy verification (AV) services offer the assurance and material traceability requirement for today’s engineering manufacturers. Whether the inspection requirement is for GO / NO GO match or full analysis of the alloying composition, Independent Integrity Inspection Limited (INDEi) can supply.
