Positive Material Identification

 

PMI (Positive Material Identification) testing is the analysis of materials to determine the chemical composition. Knowing the exact composition and grade of an alloy enables suppliers, plant workers, and other responsible parties to match alloy specifications. Techniques and methods deployed include Portable X-Ray Flourescene (XRF), Optimal Emission Spectroscopy (OES), Ferrite Testing, and Hardness Testing.

Having the right alloy in the right place is essential in places like petroleum refineries and chemical plants, because the right alloy with the right properties is often all that stands between a safe, efficient operation and lost time and revenue.

The Advanced Retro PMI inspection program is utilized as a multi-feature system minimizing the amount of insulation and scaffolding needed, while identifying, documenting, and verifying material specifications.
