Non-Destructive Testing (NDT)

Non-destructive testing is exactly as the name implies – testing that is performed without destroying or impacting the integrity of the items tested. A diverse range of industries use NDT to detect defects and irregularities and assess safety in equipment and assets, and the growing need to utilize NDT is a result of companies looking to extend the life of equipment, plant facilities and other assets in addition to adhering to increased regulations.
NDT helps to protect the investment made in plant infrastructure by providing the valuable data needed to detect, monitor and improve processes and assets. NDT also helps manufacturers in assessing components and products for quality and possible failure. Potential damage to a company’s reputation and brand can be avoided by utilizing NDT to ensure the products’ safety and reliable operation.
Today modern nondestructive tests are used in manufacturing, fabrication and in-service inspections to ensure product integrity and reliability, to control manufacturing processes, lower production costs and to maintain a uniform quality level. During construction, NDT is used to ensure the quality of materials and joining processes during the fabrication and erection phases, and in-service NDT inspections are used to ensure that the products in use continue to have the integrity necessary to ensure their usefulness and the safety of the public.
Current NDT methods are
Acoustic Emission Testing (AEТ)
Electromagnetic Testing (ET)
Guided Wave Testing (GW)
Ground Penetrating Radar (GPR)
Laser Testing Methods (LM)
Leak Testing (LT)
Magnetic Flux Leakage (MFL)
Microwave Testing
Liquid Penetrant Testing (PT)
Magnetic Particle Testing (MT)
Neutron Radiographic Testing (NR)
Radiographic Testing (RT)
Thermal/Infrared Testing (IRT)
Ultrasonic Testing (UT)
Vibration Analysis (VA)
Visual Testing (VT)
And other advanced technologies NDT (ADV NDT)
The six most frequently used test methods are MT, PT, RT, UT, ET and VT.
At TWN our customized solutions for each customer help us to work in a wide variety of industries including oil and gas, power generation, petrochemical, aerospace, defenses, marine, rail, submarine, foundries and general engineering.
We offer both conventional and advanced NDT methods to provide a complete examination of components, equipment and assets. Our on-going commitment to providing the best in NDT means we invest in the latest innovative technology and training for our expert staff. This technology, combined with our expertise and consistently reliable support, give you the assurance you need that quality and safety risks are minimized and operations are performing at optimal levels.
