All objects emit electromagnetic radiation of a wavelength-dependent on the object’s temperature. The wavelength of the radiation is inversely proportional to the temperature. Infrared and thermal testing involves temperature and …
ASME B16.34 Valves–Flanged, Threaded, and Welding End covers pressure-temperature ratings, dimensions, tolerances, materials, nondestructive examination requirements, testing, and marking for cast, forged, and fabricated flanged, threaded, and welding end and …
Leak testing is a form of nondestructive testing used in either pressurized or evacuated systems and components for detection and location of leaks and for measurement of fluid leakage. leak …
Acoustic Emission Testing is a qualitative NDT method. It differs from most other nondestructive testing (NDT) methods in two key respects. First, the signal has its origin in the material …
The casting process is widely used in the manufacturing industry, hence it is very important for an NDT personnel to have a sound knowledge of the process and the steps …
Radiography is a volumetric NDT test method used to determine internal flaws in castings and Welds. Radiographic testing includes passing of X-rays or Gamma Rays through the test item from one …
Defectology in NDT deals with the defects that affect all the stages of product realization, starting from raw material to finished product. Discontinuities are imperfections in a test object that …
This Radiography Test Procedure is written with reference to ASME BPVC Sec-V, Article 2 & 22 for film base radiography of castings and welds with X-rays/Gamma Rays using industrial radiographic film. This …
The magnetic particle examination NDT method is applied to detect cracks and other discontinuities on the surface/slightly subsurface of ferromagnetic materials. The sensitivity is greatest for surface discontinuities and diminishes …
In the industry most of the time, it is important for the NDT inspector to be able to locate the source of the problem when it exists, or even when …
