How to Use PMI Testing for Gas and Steam Turbine Components
Power plants depend on gas and steam turbines to produce electricity efficiently and safely. Failures in these systems, often due to incorrect materials, can have devastating consequences. Positive material identification (PMI) acts as a vital defense against such failures. PMI testing employs cutting-edge technology to confirm the chemical composition of metals without causing harm. This...

Positive Material Identification in Turbine Repair – Why it Matters
A single misidentified alloy during turbine component repair can destroy months of careful maintenance planning. Your power plant’s next scheduled outage involves millions in contractor costs, replacement parts, and lost generation revenue—all riding on the assumption that every component meets its material specifications. But what if that replacement blade contains 12% chromium instead of the...
