Advanced NDT techniques have revolutionized the way industries perform quality checks and ensure the safety of their equipment and structures. However, these techniques would not be possible without the advanced NDT products used to perform them. In this article, we will explore some of the advanced NDT products used to perform techniques like computed tomography (CT) scanning, thermography, acoustic emission (AE) testing, digital radiography (DR), eddy current array (ECA), laser shearography, and phased array ultrasonics (PAUT).
1. Computed Tomography (CT) Scanners
Computed Tomography (CT) Scanners are one of the most widely used NDT products. These scanners use X-ray technology to create highly detailed 3D images of the internal structure of a material or component. CT scanning is a powerful technique that can detect a wide range of defects, including voids, cracks, and inclusions. CT scanners are commonly used in aerospace, medical, and industrial applications, and are considered a staple in advanced NDT.
2. Infrared Cameras
Infrared Cameras are another vital piece of equipment used in advanced NDT. They are used in thermography to detect temperature variations on the surface of a material or component. These variations can indicate the presence of defects such as leaks, cracks, or corrosion. By detecting these defects early on, they can be addressed before they become a more significant problem. Infrared cameras have a wide range of applications and are commonly used in the power generation, aerospace, and building inspection industries.
3. Acoustic Emission Sensors
Acoustic Emission Sensors are also used in advanced NDT. These sensors are used to detect and locate specific types of defects such as cracks, corrosion, and leaks in pressurized systems. The sensors are sensitive to sound waves and can detect the ultrasonic vibrations caused by defects within the material or component. They are commonly used in the oil and gas, power generation, and aerospace industries.
4. Digital Radiography (DR) Detectors
Digital Radiography (DR) Detectors are used to capture radiographic images digitally, rather than on film. DR detectors offer faster image acquisition, higher resolution, and the ability to manipulate images digitally. These detectors are commonly used in the aerospace and medical industries, where high-resolution images are critical for ensuring safety.
5. Eddy Current Array (ECA)
Eddy Current Array (ECA) Probes are used to detect subsurface defects in conductive materials. They use multiple sensors to detect variations in electromagnetic fields generated by the material or component. ECA probes are commonly used in the aerospace and industrial sectors, where safety and quality control are of the utmost importance.
6. Laser Shearography Equipment
Laser Shearography equipment is another advanced NDT product used to detect surface and subsurface defects in materials. It uses laser technology to measure surface deformations caused by internal defects within a material or component. Laser shearography is commonly used in the aerospace and power generation industries.
7. Phased Array Ultrasonic (PAUT) Probes
Phased Array Ultrasonic (PAUT) probes are used to create high-resolution images of the internal structure of a material or component. They use multiple sensors and advanced signal processing to create detailed images of the material's structure. PAUT probes are commonly used in the aerospace, power generation, and medical industries.
8. Neutron Radiography Equipment
Neutron Radiography equipment is used to create radiographic images of a material or component using neutrons instead of X-rays. Neutron radiography is commonly used in the aerospace and nuclear industries, where high levels of radiation exposure are a concern.
In conclusion, advanced NDT products have revolutionized the way industries perform quality checks and ensure the safety of their equipment and structures. These products are commonly used in specialized industries such as aerospace, nuclear, and energy, and require specialized training and equipment, as well as experienced operators. While they can be more expensive than basic NDT equipment, the benefits of advanced NDT techniques and products far outweigh the costs.
