Importance of PMI
One of the most common causes of industrial accidents is failures in mechanical integrity. Examples of this include rupture of pressurized systems, stress corrosion cracking, flow accelerated corrosion especially in power/nuclear plant technology, and insufficient strength of welded joins.
Positive material identification can prevent potential product failure in manufacturing. At oil and gas, power generation and pharmaceutical plants, pre-service and in-service inspection of critical components and welds with PMI can prevent breakdown and its potentially costly and dangerous consequences.
PMI testing means that companies can make sure that every single part in their system meets specifications, critical replacement parts are the right alloy grade and all new materials are exactly what they should be. This important step can be the key difference between seamless operations and catastrophic safety failures.
