PMI Equipment: XRF for PMI

As Positive Material Identification (PMI) requirements continue to become more and more stringent, so does the need for PMI equipment that provides nondestructive analysis become greater and greater. XRF (x-ray fluorescence) is a commonly used, accurate, fast, nondestructive technique for testing pipes, valves, bolts, flanges, rivets, and any other metal component for appropriate alloy composition, both in-process and in stock. The American Petroleum Institute (API) requires that such testing be done in order to avoid materials mix-ups, which can easily result in devastating accidents in the refinery environment. API RP 578 outlines the processes and procedures for using XRF for Positive Material Identification (PMI) in petrochemical plant and refinery operations. Today, the industry standard is 100% alloy material verification. Fortunately, XRF analyzers can help you meet the challenge of PMI and OSHA compliance.

Why Choose XRF Instruments for Your PMI Equipment Needs?

XRF Analytical Instruments is a leading provider of handheld PMI equipment for refineries and inspection companies, as well as handheld and benchtop XRF instruments for the analysis of alloys in high-reliability applications such as aerospace and high-reliability alloy manufacturing. XRF Analyzers contain many state-of-the art features specifically engineered with the PMI customer in mind. The extensive alloy grade library contains all the alloy grades that one might find in a refinery setting, from the most common to the exotic. Apart from providing accurate grade identification every time, your XRF Analyzer provides you with accurate element-by-element alloy chemistry in a matter of seconds, allowing you to catch even the slightest discrepancies. Alloy types that can be quickly, accurately identified with Handheld XRF PMI analyzer include:

• Steels: Stainless, Cr-Mo, Low Alloy, Tool, etc.
• Copper Alloys
• Nickel Alloys
• Titanium Alloys
• Aluminum Alloys
• Exotics

Perhaps the most important feature of the Handheld XRF analyzer for PMI is the silicon drift detector (SDD), the most powerful, state-of-the-art detector available in a handheld EDXRF system, offering lab quality results at unparalleled speeds. The silicon drift detector offers significantly lower limits of detection, better signal-to-noise ratio, superior accuracy, and increased speed as opposed to silicon PiN (Si-PiN) detectors, found in some handheld XRF instruments. SDD detectors come standard in many Handheld XRF instruments. No need to choose between value and performance!
