When you need to know what your metal really is
PMI Specialists, Inc. has delivered positive material identification, metallurgical testing, and failure analysis to refineries and pipelines since 1992. PhD materials engineers in the lab and in the field, catching the mis-stamped alloy before it becomes a catastrophic release.
One wrong alloy can shut down a unit, or worse
Studies show almost half of the largest refinery losses trace directly to piping-system failures. PMI testing reduces or eliminates the workplace hazards tied to the catastrophic release of highly hazardous chemicals, per OSHA and API guidance. We routinely find components stamped one grade and made of another.
- !Stamped "SS 304L", actually 316Wrong corrosion and service behavior than the drawing calls for.
- !Marked "WCB", actually SS 304A carbon-steel casting spec on a stainless part (or vice versa).
- ✓Verified before it goes in the groundPositive identification that protects the project, the schedule, and the crew.
Lab precision and field mobility, under one roof
From portable XRF at a tie-in to SEM-EDS in the lab, PMI Specialists covers the full materials-analysis workflow with the same PhD-level rigor.
Positive Material Identification
Verify alloy chemistry on site with portable XRF, OES, and LIBS before material goes into service.
Field ServicesAutomated Ball Indentation
Non-destructive yield-strength testing on live pipelines and equipment: no coupon removal.
Field ServicesFailure Analysis
Root-cause metallurgical investigation of cracked, corroded, and failed components.
Lab ServicesSEM-EDS
Scanning electron microscopy with elemental micro-analysis for fractures and deposits.
Lab ServicesMetallography
Microstructure examination, grain structure, and weld quality on an Olympus 3-D optical microscope.
Lab ServicesRentals & Calibration
Rent field-ready XRF, OES, LIBS, hardness, and UT instruments, with XRF/OES calibration.
