For those customers that may have a Positive Material Identification (PMI) requirement, Pima Valve has the capabilities to do such. Fees are dependent on the extent of the requirement.
PMI takes two primary forms. The first is called Optical Emission Spectrometry (OES) and is generally more difficult and time consuming. The second, and more user-friendly method, is called X-Ray Fluorescence (XRF). As the name implies, it fires X-rays at the subject metal and determine its composition. An XRF Analyzer is shaped like an over-sized ray gun from a science fiction show (see inset), but it is portable, accurate, and simple to use. Training to use one can be done in as little as a few hours.
Once a casting has been scanned, the results can be downloaded into a useful database format right to a computer. From there, the data can be output into reports or Certificates of Conformance supported by empirical data, ensuring that your valves meet every requirement, every time.
