WHAT IS NDT?
Non-destructive testing (NDT) is a descriptive term used to examine materials and components in such a way that allows materials to be examined without changing or destroying their usefulness. NDT can be used to find, size, and locate surface and subsurface flaws and defects.
NDT plays a crucial role in everyday life and is necessary to assure safety and reliability. Typical examples are found in pipelines, bridges, trains, power stations, refineries, infrastructures such as buildings and bridges, oil platforms, and aircraft inspected using NDT.
NDT is a Quality Assurance management service and requires an understanding of the various methods available, their capabilities and limitations, knowledge of the relevant standards and specifications for performing the tests.
WHY IS NDT IMPORTANT?
Non-destructive testing can be applied to each stage of an item's construction. NDT is important for the following reasons:

High-energy piping (HEP) systems in power plants contain critical components requiring careful maintenance and inspection. We offer clients an integrated, multidisciplinary High-energy piping (HEP) management program development and management to ensure these crucial systems' safe and reliable operation. Our team has expertise in Creep Strength Enhanced Ferritic (CSEF) steels such as Grades 91 and 92. AIS offers a full range of HEP services specializing in HEP Program development and management. These cost-effective tools maximize the efficiency of lifecycle management budgets. Our fitness-for-service (FFS) analysis, Non-destructive testing (NDT), and metallurgical lab analysis provide a customized HEP program to fit plant needs.
Once management is established, in-service can be implemented to control damage in high-temperature piping systems which are subject to creep. These services are important to maintain asset quality and requires different skills and procedures than performing a code-acceptance inspection. Our NDT professionals are trained in advanced NDT techniques specifically designed to locate damage to equipment operating at high temperature and high pressure, including components made from advanced materials such as Grade 91 and Grade 92.
We evaluate new and old piping systems by utilizing a multidisciplinary approach with material specialists and analytical engineers; assessing existing conditions, providing recommendations, and overseeing changes to critical component systems.
Our experience with the root causes combined with tube failure and condition assessment, conducted by our metallurgical lab, results in recommendations saving the plant from potential future losses.
Since the catastrophic failure of tubing and piping can occur with little or no warning, our FAC programs identify locations most susceptible to FAC damage.
