Positive Material Identification (PMI) is the fast and reliable non-destructive verification of the chemical composition of metals and alloys. It is used in particular to prevent the use of incorrect materials in critical systems and to ensure quality assurance.
TESKO performs PMI testing with XRF and OES instruments, carrying out the chemical verification of stainless steel, alloy steel and other metal groups. Results are reported in accordance with international standards.
Typical Applications
- Alloy verification of piping and fittings
- Material confirmation of welds and consumables
- Incoming material and vendor inspection
- Positive material traceability for critical service
- Refinery and petrochemical alloy checks
- Prevention of material mix-ups in fabrication
Why PMI (Positive Material Identification)?
- Non-destructive — parts stay in service
- On-site results in seconds with portable XRF
- Full alloy grade identification with OES
- Documented traceability against specification
