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.
SCOPE. 1.1 This standard establishes basic requirements for conducting Positive Material Identification (PMI) tests on ferrous and nonferrous metal alloy materials using portable x-ray emission type equipment, which is currently available for production shop and construction site verification of these materials.
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.
We will explain the need and requirements for “Positive Material Identification” (PMI) using Portable X-Ray Fluorescent (XRF) and Mobil Optical Emission Spectroscopy (OES) Technologies. The purpose of the Course is to certify and re-certify Non Destructive Technology (NDT) inspectors, in understanding and applying API RP 578 through an ...
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.
Positive Material Identification (PMI) analyzers for safety inspection and pipeline integrity. Tough legislation around material testing has set the bar high for the instruments used for positive material identification (PMI) within petrochemical, petroleum, power and chemical plants.
