Advance NDT Services

Non-Destructive Testing has radically changed emphasis over recent years from a focus on detecting defects arising during the manufacture of new products, to detecting process induced integrity problems. Globe Inspection has established itself at the forefront of an NDT technological revolution by a process of investment in state-of-the-art equipment and specialized training to meet this step-change. The result is an infrastructure that offers a comprehensive range of Advanced NDT (ANDT) that individually or in combination provides state of the art solutions to the ever-increasing demand for Non-Invasive Inspection.


From strategically located centers of excellence, our services are coordinated on a worldwide basis and offer a proven record of delivering a safe, technically sound and cost effective service. The Globe Inspection department employees experienced fully qualified ASNT NDT level III technical support personnel who maintain the organizations competitive advantage by constantly monitoring and evaluating incremental and radical innovations in inspection technology.


PAUT is an advanced NDT technique that utilizes a set of UT probes made up of numerous small elements, each of which is pulsed individually with computer- calculated timing. This technique can be used to inspect more complex geometries that are difficult and much slower to inspect with single probes. PAUT can be used to inspect almost any material where traditional UT methods have been utilized and is often used for weld inspections and crack detection. Compared to other forms of UT, PAUT has several advantages. PAUT can be conducted more quickly than other forms of UT, often within a fraction of a second. It can easily be used for repeat scans because it has a high degree of repeatability. By emitting beams of multiple different angles sequentially, PAUT is able to create detailed and accurate cross-sections of a part. It is also particularly useful in situations where there is less room for mechanical scanning because it’s able to sweep the beam without moving the Probe.

Is a reliable method of nondestructive ultrasonic testing (UT) used to look for flaws in welds? TOFD uses the time of flight of an ultrasonic pulse to find the location of a reflector. It can also be used for weld overlays and the heat-affected zones of other components as well such as piping, pressure vessels, clad material, storage tanks, and structural steel. To do this, TOFD uses a pair of ultrasonic transducers, one as a transmitter and the other as a receiver. The low-frequency waves propagate at an angle and only diffract back to the receiver if they hit a defect. If this happens, the time it takes for both waves to make it to the receiver can be used to create a complete image of the weld and identify the size and location of the damage.

(MFL) is a nondestructive examination technique that uses electromagnetism to inspect for flaws or material degradation in steel structures. In the oil and gas industry, it is often used to search for flaws in piping and pipelines, as well as aboveground storage tank floors. MFL uses magnets to temporarily magnetize the structure. If there are flaws present, the magnetic field created will show distortions, signaling the presence of things like corrosion, pitting, and wall loss.

ECT is used for inspecting steam generator tubing in nuclear plants and heat exchangers tubing in power and petrochemical industries. The technique is very sensitive to detect and size pits. Wall loss or corrosion can be detected but sizing is not accurate. Eddy current testing is now a widely used and well-understood inspection technique for flaw detection, as well as thickness and conductivity measurements. The magnetic field oscillates at the same frequency as the current running through the coil. When the coil approaches a conductive material, currents opposed to the ones in the coil are induced in the material
