Positive Material Identification (PMI Testing) Services
Rapid on-site Positive Material Identification (PMI) testing for alloy grade confirmation, incoming raw material verification, and critical weld metallurgy. Testing is performed by appropriately qualified and certified NDT personnel in accordance with applicable codes, standards, specifications, and approved procedures.
Principle & Testing Methodology
Positive Material Identification uses handheld X-Ray Fluorescence (XRF) spectrometry to bombard metal atoms with primary X-rays. Dislodged inner-shell electrons cause outer electrons to transition, releasing characteristic secondary fluorescent X-rays unique to each element. Detectors measure intensities to calculate elemental concentrations within seconds.
Defects & Discontinuities Detected
- Material mix-ups in warehouse raw materials or fabrication stock
- Incorrect filler wire used during alloy weld assembly
- Accidental substitution of SS 304 in place of specified SS 316
- Non-conforming carbon, chrome, nickel, or molybdenum concentrations in high-temp alloys
Typical Industrial Applications & Components
- Receiving inspection of alloy plates, pipes, fittings, and flanges
- In-service process piping and reactor vessel alloy verification
- Critical weld metal chemistry confirmation in power & petrochemical units
- Scrap metal sorting and high-value alloy recovery
