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.
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.
Positive Material Identification is the detection of materials through non-destructive element spectrometry in samples of metals, steel, and alloys, which is used to check the component composition of ores, soils, and other liquid and powder samples.
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.
Review how XRF is used for positive material identification (PMI) and weld inspection for the oil and gas (O&G) sector. Testing methods, sample considerations, and strategies and tools for data management are discussed.
Positive Material Identification (PMI) can prevent mix-ups that can result in component failure, which can cause costly downtime, repair and replacement, lost (leaking) material, environmental and fire hazards, or batch contamination.
