Radiography uses X-rays and gamma rays to measure thickness and internal features; detect surface and subsurface defects; and provide details of material through film or other detector. This technology is widely used in oil and gas industries; security, and many other possible applications to gain an optimal quality of the operation.
This method uses high frequency sound waves and energy to determine flaws, inspect material properties and any change in thickness. Ultrasonic locates surface and subsurface defects in materials like plastic, metal, woods, and others. Welding inspection is one of the industry that benefits this technology, aside from oil and gas, automotive, power plant, and other industries that require inspection.
Robotic non-destructive testing (NDT) is a method of inspection used to assess the structural integrity of petroleum, natural gas, and water installations. Crawler-based robotic tools are commonly used for in-line inspection (ILI) applications in pipelines that cannot be inspected using traditional intelligent pigging tools (or unpiggable pipelines).
Robotic NDT tools can also be used for mandatory inspections in inhospitable areas (e.g., tank interiors, subsea petroleum installations) to minimize danger to human inspectors, as these tools are operated remotely by a trained technician or NDT analyst.
Penetrant inspection is applied to detect cracks or porosity on the surface of the material. Penetrant fills the cracks then a developer is used to pull the penetrant and see the form of defect. The application is exerted on automotive, welds, casting, leak testing, pipeline, aircraft and vessels, power plant inspection, just to name a few.
Magnetic Particle Testing uses magnetic field to inspect ferromagnetic material. The magnetic lines then forced to travel through materials to detect surface and near surface defects; and is widely used for welds, pipelines, automotive industries, military, and other needs of crack detection.
Eddy Current takes alternating electrical current to produce their own magnetic fields which can be measured and used to find flaws. This method detects surface and near-surface flaws in conductive materials,) permeability, and dimensional features. It is mainly applicable in oil and gas, mining, security, aviation, other industries.
