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.
Learning Objective. At the conclusion of this course the student will: Understand the applicability of ratio and proportion estimating methods; Learn the technique to factor costs to correspond to varying equipment sizes and capacities; Learn the technique to escalate or otherwise adjust historical costs. Intended Audience.
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.
1. 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 (PMI) is a way that engineers or technicians can verify that a part was manufactured out of the correct material or that the correct material is being installed. It is also commonly referred to as Alloy Verification (AV) or Positive Material Verification.
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.
