Positive material identification, or PMI, is a method of nondestructive testing (NDT). It is as critical for quality control and assurance as it is for safety, says Matt Kreiner, head of global product management, Hitachi High-Tech.
The ability for producers to manufacture quality goods starts with having safe, reliable operations, and PMI is central to any mechanical integrity program, providing a quick way for inspectors to identify risk factors within the facility and avoid potentially hazardous situations, Kreiner says.
