PMI quickly and accurately identifies the composition of more than 100 different engineering alloys on-site. Our team can perform PMI on virtually any size or shape of pipe, plate, weld, welding materials, machined parts or castings. We perform both X-Ray Fluorescence (XFR) and Optical Emission Spectroscopy (OES), two methods of conducting a PMI examination. Both methods ensure compliance with Process Safety Management (PSM) requirements.
