  1. Positive material identification (PMI) is used to analyse and identify material grade and alloy composition for quality and safety control. A rapid, non-destructive method, positive material identification is performed on a wide range of components and assets, and provides a semi-quantitative chemical analysis.

  2. Positive Material Identification (PMI) is a fast and non-destructive testing (NDT) method for verifying the chemical composition of metals and alloys. PMI can be used to verify that supplied materials conform to the proper standards and specifications.

  3. 31 maj 2023 · This article covers the guidelines for positive material identification (PMI) of pressure-retaining alloy material components, alloy bolting, welding consumables, welds, weld overlays and cladding. PMI examination may be carried out at the fabricators, vendors or material suppliers facility.

  4. Learn about two key technologies of choice for positive material identification (PMI) in midstream and downstream operations: handheld XRF and LIBS analysis, including the latest capabilities for PMI in the commissioning process or for retroactive inspection of existing assets.

  5. The DELTA Element is a cost-effective handheld X-ray fluorescence (XRF) analyzer optimized for scrap metal sorting, positive material identification (PMI), alloy QA/QC, and precious metals analysis.

  6. This procedure prescribes the requirements for the positive material identification (PMI) for vessels and piping to verify that alloy materials are of acceptable chemical composition independent of any certificate and marking that may exist, and to assure that correct alloy materials are used at the places where intended.

  7. PMI Testing, also known as Positive Material Identification Testing, is the analysis of materials to determine the chemical composition of a metal or alloy at particular (usually multiple) steps of alloy manufacturing or in-process alloy installation.
