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 …
Introduction to leak testing
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 …
Introduction to Acoustic emission testing
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 …
Introduction to Casting Process
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 …
Advanced Radiography Techniques
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 …
NDT DISCONTINUITIES
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 …
