What it is
PMI Specialists provides forensic analysis for fire and explosion incidents. Our experts conduct detailed forensic analysis to determine the root cause of fire or explosion events, including metallurgical evaluation, material degradation, and contamination assessment.
How we analyze it
The investigation draws on several technical approaches:
- Examination of microstructural changes and heat-affected zones
- Analysis of residue deposits to identify the failure sequence
- Assessment of whether damage stems from material defects, design issues, operational errors, or external factors
Case study: stainless steel pipeline fire
A 20″ 316L pipeline experienced internal combustion from low-flash-point vapors. The 8–15 minute fire reached temperatures exceeding 1300°C, causing grain coarsening and potential carburization. The analysis concluded that the affected section's fitness for service was compromised due to structural and corrosion concerns, with recommendations for selective component replacement.
Case study: natural gas compressor explosion
An internal explosion occurred during restart after 4,000 operating hours, caused by oil and air contamination. Metallurgical evidence revealed martensite formation indicating temperatures exceeding 1,500°F. The analysis determined that while cooling tubes and plastic components required replacement, the bulk compressor assembly was largely unaffected.
