Nondestructive Testing (NDT) consists of a variety of non-invasive inspection techniques used to evaluate material properties, components, or entire process units. The techniques can also be utilized to detect, characterize, or measure the presence of damage mechanisms (e.g. corrosion or cracks). NDT is also commonly referred to as nondestructive examination (NDE), nondestructive evaluation (NDE), and nondestructive inspection (NDI). Many NDT techniques are capable of locating defects and determining the features of the defects such as size, shape, and orientation. The purpose of NDT is to inspect a component in a safe, reliable, and cost effective manner without causing damage to the equipment or shutting down plant operations. This is in contrast to destructive testing where the part being tested is damaged or destroyed during the inspection process.

Within one unit, TriLat combines the power of two probes containing three angle beam sets to identify and quantify cracking at early stages. The result is inspection speeds up to ten times faster than traditional AUT systems, depending on probe size.
FFS assessment techniques are applicable to a wide range of damage types: LTA's, cracks, creep damage, dents, and more. These are very powerful analytical tools that often allow operators to not only keep the plant running, but to keep it running...
The availability of high quality UT data is often the cornerstone for FFS and RBI decisions. As such, the API Subcomittee for Inspection and Integrity Management (SCIIM) has initiated a program for the Qualification of Ultrasonic crack Sizing...
Detecting, quantifying, and sizing indications characterized as a crack" in critical equipment have long been the global benchmark of asset integrity programs. Therefore, the increased precision that inspection programs obtain using advanced...
In the last few years, electromagnetic acoustic transducer (EMAT) has come to prominence for its ability to quickly scan exposed pipelines for corrosion, cracks, and other defects using medium-range guided waves and without the requirement for...
A small leak from top tubesheet-to-tube welds prompted further inspection of the 1Cr- Mo Ammonia Converter Boiler Feed Water (BFW) Exchanger during a planned shutdown. Further cracks were identified in the top channel to tubesheet butt weld that...
Once again there is a crack found in the inlet tubesheet in your high-pressure high temperature heat exchanger. As head of the maintenance engineering effort, you know that plant management will ask you if it can run safely and reliability until...
Hydrogen-induced cracking is a damage mechanism commonlyobserved in the petroleum refining industry [1, 2]. The damage appears as laminar cracks and blisters, which can link up in the through-wall direction to form stepwise cracking. 2ff7e9595c
