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.
The equipment cost estimating methods that will be outlined in this course are suitable for use with the first three types of estimates; definitive and detail estimates require formal, firm equipment cost quotations from equipment manufacturers and suppliers.
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 (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.
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.
