Nondestructive testing (NDT)
Nondestructive testing (NDT) is a wide group of analysis techniques used in science and technology industry to evaluate the properties of a material, component or system without causing damage. The terms nondestructive examination (NDE), nondestructive inspection (NDI), and nondestructive evaluation (NDE) are also commonly used to describe this technology. Because NDT does not permanently alter the equipment being inspected, it is a highly valuable technique that can save both money and time in product evaluation, troubleshooting, and research.
The six most frequently used NDT methods are eddy-current, magnetic-particle, liquid penetrant, radiographic, ultrasonic, and visual testing. NDT is commonly used in mechanical engineering, petroleum engineering, electrical engineering, civil engineering, systems engineering, aeronautical engineering, etc.
EAST Indonesia can support client for provided NDT services in two types of NDT called Conventional & Advanced methods which usually implementation at field, manufacture, building, etc. For NDT conventional methods, it is commonly are:
- Dye Penetrant Examnination;
- Magnetic Particle Examination;
- Ultrasonic Examination;
- Radiography Examination.
EAST Indonesia also provided NDT advanced method services for more specific examination which usually as a part of integrity management process of facilities during plant installed in turn around or in -service condition, manufacturing process, construction, and maintenance. NDT advanced methods can provided by EAST Indonesia such as:
- Boroscope inspection;
- Advanced Ultrasonic:
- Phased Array UT (PAUT),
- Eddy Current Array,
- Acoustic Pulse Reflectometry (APR),
- Pulsed Eddy Current (PEC),
- Time-of-Flight Diffraction (TOFD),
- Internal Rotary Inspection System (IRIS),
- Electromagnetic acoustic transducers EAT),
- Long Range Ultrasonic Testing (LRUT);
- Magnetic Flux Leakage (MFL);
- Digitalized Radiography;
