Visual inspection

 of assets is inherent in the previously outlined NDT testing methods.Physical damage, corrosion, and surface cracks are examples of anomalies that are commonly identified during visual inspection. Critical to successful application of this method are factors including the calibration and quality of the image-capturing method, the
inspector’s knowledge of the assets and their operating conditions, anomaly identification criteria, understanding of the defects, and proper documentation.

Penetrant Testing is a cost-effective method used to detect surface breaking flaws includingcracks, cold laps, and porosity. PT inspection can identify critical defects in many clean and non-porous ferrous and non-ferrous materials prior to loss of containment and prevent
costly repairs. Dye penetrant is applied to the material or structure being tested and is drawn into surface breaking flaws by capillary action. Excess penetrant on the surface is removed and a developer is applied. The developer draws the penetrant from the flaw and produces a surface indication. The technique can be applied to many ferrous and nonferrous materials that are clean and non-porous.

Magnetic particle testing is a cost-effective method used to identify surface and nearsurface flaws in ferrous materials. This testing method can be used while an asset is in
service to determine its conformity to required standards. Operators can effectively identify
required repairs and prevent costly failures and shutdown time. MT requires the application
of a magnetic field using a permanent magnet or electromagnet in the area of the
inspection. Following magnetization, the inspection area is covered with a ferrous oxide
particle detection medium, that is either dry or suspended in a liquid. Flaws distort the
magnetic field, causing local magnetic flux leakage that attracts the detection medium and
indicating the presence of a flaw.

Ultrasonic testing uses high-frequency sound waves to measure the material thickness and detect surface and subsurface flaws. It is often used to locate manufacturing defects in
welds and castings, complete corrosion and erosion monitoring, and support large-scale corrosion mapping. UT is a portable and quantitative inspection method offering flexible (Evaluates external flaws, wall thickness, and detection of internal flaws)
inspection variations including straight beam, angle beam, phased array, and Time of Flight Diffraction (TOFD). Its success requires a clean surface so that couplant can be appliedbetween the probe and the surface to enable the required sound transmission

 Radiography uses gamma rays or X-rays to Detects and evaluates wall loss and weld defects
produce an image of an object on film or on a digital detector. Images are analyzed to
detect wall loss, size pipes and plate, and to identify defects in welds, forgings, and castings
during the manufacturing process. The source of radiation is selected to suit project
requirements. Radiography enables in-house or mobile inspections, the creation of a
permanent inspection record, and provides the client with data used to determine the
suitability of inspected components prior to additional work progressing.
