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.
Positive material identification can prevent potential product failure in manufacturing. At oil and gas, power generation and pharmaceutical plants, pre-service and in-service inspection of critical components and welds with PMI can prevent breakdown and its costly consequences.
The PMI-MASTER Smart is the only truly portable high performance OES analyzer on the market, delivering analysis of key elements, rapid material verification, PMI and metal sorting. Accurately analyze elements at the lowest limits of detection, such as phosphorous, sulfur, boron and carbon.
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.
The Positive Material Identification tests, or also known as PMI test, are of great importance for the traceability of components. This non-destructive testing serves as a proof of the alloying constituents present in the material, confirming the melting analysis of the material contained in the 3.1 certificate.
