Non-destructive testing terms in Chinese and English
Non-destructive Testing
Non-destructive testing (NDT) refers to any testing technique used to evaluate a materials physical and mechanical properties without hurting or damaging it in any way. In other words, it involves testing a material in such a way that it can still be used after the testing......
Non-destructive testing noun (AD)
A: Ultrasonic Testing
Ultrasonic testing (UT) is a form of nondestructive testing used to detect and measure material defects, measure thickness, inspect for corrosion and to monitor welding processes. UT utilizes short bursts of sound energy at high frequency, usually above 1 MHz, to create sound......
Engineering logging
Introduction
Well logging is an overarching term that encompasses the use of various instruments to measure physical characteristics of a borehole and its surrounding geologic formation. In oilfield, well logging is a critical tool used to evaluate the presence and production capabilities of hydr......
Natural gamma Spectral Logging
Logging in natural γ-ray spectroscopy
Logging in natural γ-ray spectroscopy (NGS) is a technique used in the oil and gas industry to assess the content of specific materials in a specified area. This is achieved by measuring the energy of emitted γ-ray photons from natural sources, such as ura......
