BARTLEVILLE, Oklahoma -- The US Patent and Trade Mark Office has issued SGS a patent for its retro Positive Material Identification (PMI) inspection system.

The PMI system determines the alloy composition of piping and vessel materials and verifies that only the correct materials are used for intended service.

The SGS system links CAD drawings, a PMI database, field load sheets, and third party commercial data loggers. It enables pre-selection of required inspection locations where PMI analysis should be conducted and uniquely identifies each of them. Information is entered into a PMI database, which enables the preparation of field work packages and systematizes the process of loading collected measurements into the database. This optimized approach provides significant improvements for finding and reporting non-compliant materials plus performing future evaluations in response to ever-evolving fluid processing changes, according to SGS.
