Positive Material Identification (PMI)

Southern Valve Service uses Positive Material Identification (PMI) and X-Ray Fluorescence (XRF) analyzers to meet recommended standards (API RP 578 Material Verification Program for New and Existing Alloy Piping Systems) and customer specific specifications. This ensures all parts of the valve meet your requirements, critical replacement parts are the right alloy grade and all new materials are exactly the material you specify.
