Nondestructive testing or non-destructive testing (NDT) is a wide group of analysis techniques used in industry to evaluate the properties of a material, component or system without causing damage. The terms nondestructive examination (NDE), nondestructive inspection (NDI), and nondestructive evaluation (NDE) are also commonly used to describe this technology. Because NDT does not permanently alter the article being inspected, it is a highly valuable technique that can save both money and time in product evaluation, troubleshooting, and research. The Most frequently used NDT methods by Eagle Integrity Solutions are magnetic-particle, dye penetrant, radiographic, ultrasonic, and visual testing.
NDT is commonly used in forensic engineering, Mining, mechanical engineering, petroleum engineering, electrical engineering, civil engineering, systems engineering, aeronautical engineering.

Ultrasonic nondestructive testing, also known as ultrasonic NDT or simply UT. It’s a method of characterizing the thickness or internal structure of a test piece through the use of high-frequency sound waves. Ultrasonic Inspection is a very useful and versatile NDT method. Some of the advantages of ultrasonic inspection that are often cited include:

  •  It is sensitive to both surface and subsurface discontinuities.
  • The depth of penetration for flaw detection or measurement is superior to other NDT methods.
  • Only single-sided access is needed when the pulse-echo technique is used.
  • It is highly accurate in determining reflector position and estimating size and shape. Minimal part preparation is required.
  • Electronic equipment provides instantaneous results.
  • Detailed images can be produced with automated systems.
  • It has other uses, such as thickness measurement, in addition to flaw detection.
  • As with all NDT methods, ultrasonic inspection also has its limitations, which include:
  • Surface must be accessible to transmit ultrasound.
  • Materials that are rough, irregular in shape, very small, exceptionally thin or not homogeneous are difficult to inspect.
  • Cast iron and other coarse grained materials are difficult to inspect due to low sound transmission and high signal noise
radiographic testing

Radiographic Testing (RT) or Industrial Radiography, is a non-destructive testing (NDT) method of inspecting materials for hidden flaws by using the ability of short wave length electromagnetic radiation  (High Energy Photos) to penetrate various materials.

Guided Ultrasonic inspection

The system uses flow frequency guided ultrasonic waves to inspect tens of metres of pipe from a single remote location. The ability of this system to send waves along the length of the pipe, means that, very difficult to inspect areas, such as crossings, can be interrogated from a remote & easily accessible location. The inspection can usually be performed while the pipe is in service.

RFD Rail Inspection

Digital Ultrasonic Rail Flaw Detector is a newly developed digital ultrasonic equipment of flaw detection. It is used to detect all kinds of flaws in rails materials ranged from 43kg/m – 75kg/m. It is a new type of practical & reliable instrument in rail flaw detection.

Phased Array Weld Inspection

Phased Array is at the heart of manual and semi automated weld inspection solutions which is developed for the Oil & Gas industry. These systems can be used for inspection in compliance with ASME, API and other code criteria, while offering high speed detection capabilities and facilitating indication interpretation.

Handwave SRT Rail Flaw detection

HANDWave is able to assess welds for flaws. Type of welds: Thermit, HPG, FB. The HANDWave can, detect defects to the bottom of the weld in good conditions and if the grain structure is small enough. HANDWave detects flaws in continuous motion on rail as demonstrated below.

magnetic particle inspection

Magnetic particle inspection (MPI) is a non-destructive testing (NDT) process for detecting surface and slightly subsurface discontinuities in ferromagnetic materials such as iron, nickel, cobalt and some of their alloys. The process puts a magnetic field into part.

dye penetrant inspection

Dye penetrant inspection (DPI), also called liquid penetrant inspection (LPI) or penetrant testing (PT), is a widely applied and low-cost inspection method used to locate surface-breaking defects in all non-porous materials (metals, plastics, or ceramics).

corrosion mapping

Zero-degree inspection just became even more accessible. For corrosion or composite inspection, field proven solutions are offered for detection of anomalies or wall loss. A scanner has been designed to offer the best inspection solution for detecting wall-thickness reductions resulting from corrosion, abrasion, and erosion. In addition systems can detect mid-wall damage , such as hydrogen-induced blistering and manufacturing-induced delamination, and clearly differentiates such anomalies from loss-of-wall-thickness. Phased Array technology offers superior inspection speed, data point density, and detection.

TOFD Inspection

TOFD is an easy and efficient approach for primary detection in weld defects. It is quick, cost-effective and capable of sizing defects present in the volume of the weld, which can be a problematic area for manufacturing defects.

component inspection

Using Ultrasonic techniques, inspection of components can detect cracks , wall loss, and other damage. With the capacity for both Angle and linear zero-degree beams, it is a very cost-efficient solution for this type of single-group inspection.

pressure vessle testing

A complete inspection of pressure vessel welds can be done in a single scan. By combining TOFD and PA in a single inspection pass, a significant reduction in inspection time can be achieved as compared with conventional raster scanning or radiography. Furthermore inspection results are available immediately, enabling you to detect problems with welding equipment and fix them right away.

small pipe inspection

When coupled with a manual scanner, the flaw detector is capable of inspecting pipes ranging from 0.84in. to 4.5in. With a very slim design, the manual scanner is able to inspect pipes in areas with limited access. Adjacent obstructions such as piping, supports, and structures can be as close as 12mm (0.5 in.).
