As the name suggests, NDT (Non-Destructive Testing) refers to a range of inspection techniques that allow inspectors to acquire data about material without destroying it.
That’s Non-Destructive Testing or NDT. A wide range of inspection methods is used to evaluate and collect data on material, system, or component without causing irreversible damage to it.
Also, NDT may be referred to as:
- NDE (non-destructive examination or evaluation)
- NDI (non-destructive inspection)
A non-destructive inspection method, inspection instrument, or the entire area of non-destructive inspections are often referred to as NDT.
Critical infrastructure must be properly maintained in order to avoid catastrophic accidents, and this is what NDT is all about.
While non-destructive testing (NDT) Malaysia is often associated with industrial applications, such as evaluating weak areas in a boiler used in an oil refinery, medical applications are really some of the most popular. Having an ultrasound to check on the health of a newborn or getting an X-ray to understand more about an accident would be examples of NDT use cases.
Despite this, it’s crucial to highlight that NDT does not require the usage of special tools.
Because they are collecting data on the condition of the boiler without causing damage, inspectors in industrial settings might use NDT to examine a pressure vessel’s outside with their naked eyes. When utilizing an ultrasonic sensor to look for faults in material or assets, this is also known as non-destructive testing (NDT).
- Savings. As a matter of fact, NDT is more enticing than destructive testing because the substance or object being inspected can survive the examination uninjured, saving time and money.
- Safety. NDT is especially intriguing due to the fact that practically all NDT procedures (excluding radiographic testing) are completely safe for humans to perform.
- Efficiency. As a result of NDT technologies, assets may be evaluated thoroughly and reasonably quickly, which can be vital for maintaining safety and performance on a construction site.
- Accuracy. For maintenance operations aimed to assure the safety of employees as well as the longevity of equipment, NDT methods have proven to be both accurate and predictable.
As the lifeblood of a well-run facility, nondestructive testing is essential to its success. NDT methodologies and reproducible outcomes rely on highly qualified experts with experience and integrity to deliver them successfully and consistently. Certified professionals perform and interpret industrial NDT methods. However, he or she also needs to know how to operate the equipment used to obtain data. Having an understanding of the equipment’s capabilities and limits can mean the difference between accepting or rejecting the product.
When it comes to NDT data gathering, there are multiple ways that each requires their own gear, training, and preparation.
A few of these approaches may allow for a complete volumetric inspection of an object, while others may just allow for surface inspection. NDT methods have varying degrees of success depending on the material they’re applied to, and some techniques, such as Magnetic Particle NDT for example, will only function on specific materials, as well (i.e., those that can be magnetized).
