As the specifications for materials employed in industry becoming more specific, the requirement for Positive Material Identification PMI verification is more relevant than ever before. Maintenance shutdowns are less frequent leading to gear requiring longer service life and reliability. As technology develops an ever increasing assortment of alloys that are indistinguishable to the eye are being employed in individual plants. When maintenance staff replace operational and key parts, they must be able to guarantee the new part matches all of the engineering specifications.
Recent business events have increased the appreciation of the requirement for accurate and comprehensive Positive Material Identification PMI inspections
If you are involved in the petroleum and petrochemical refining industries, or Sea, Automobile, Manufacturing, or Aerospace in today's world best practices and QC the stress is on safety and accident prevention and reliability hasn't ever been greater - increased safety laws, and more tough OH&S oversight and fines. Positive material identification (PMI) in alloys and materials used throughout the physical plant and producing processes is not a choice, but a necessity. The random testing of parts and sub-assemblies is now absolutely unsatisfactory. Today's best practices require 100% positive material testing of all critical materials.
The portable XRF method used to figure out the chemical composition of the material is valid for the identification of the principal amalgamating elements only. In most cases this provides satisfactory info to enable a moderately trustworthy estimate of the material type. This strategy can't notice light elements such as carbon and therefore the sole analysis should not be used to select materials for applications where the material's strength is imperative. For detailed steel material identification, either a full chemical analysis using OES or ICP should be performed or supplementary mechanical tests should be performed.
The 2 main Positive Material Identification PMI technologies used for amalgamate identification are X-ray Fluorescence (XRF) and Optical Emission Spectroscopy (OES) LMATS use both where applicable.
