Positive Material Identification (PMI) instantly provides alloy chemistry and grade ID information using a handheld portable tube-based analyzer. This method negates having to transport, alter or damage the material. PMI is also used to ensure that the base material in vessels and pipe spools is composed of the specified composition (i.e. 304 or 316L). It also ensures the correct filler material was used if the component was welded. 

PMI is an integral part of process safety management in many industries including gas and oil, petrochemical, and petroleum refining. Our PMI is used for quality control, sorting of scrap material, failure analysis, and materials testing to provide verification of metal alloy grade and composition. These assessments are crucial to meet today’s safety requirements. 

CQI prides itself in providing certified operators for PMI testing of various shapes, plate, pipes, flanges, welds, valves, and other components. Our large library (grade definitions) in our analyzer includes the most common grades used in industries and numerous specific grade compositions. We can quickly and accurately analyze the material to assess the grade and its composition.
