As an industrial power, China has also experienced qualitative development in the industrial field. Industrial CT can be used in the field of industrial flaw detection and nondestructive testing. It can quickly and non destructively detect the internal structure, composition and defects of objects by using rays, and can clearly and accurately present two-dimensional sectional images and three-dimensional images. The images have the advantages of high resolution and high precision, can be detected in real time, and can detect large industrial components. For example, in the field of general manufacturing, industrial CT can detect the defects and thickness of seamless steel pipe; In the high-tech industry, industrial CT can detect the parts of aircraft, rockets, weapons and other equipment. Industrial CT is the most excellent nondestructive testing and nondestructive evaluation technology, which plays a vital role in the development of industrial field.

NDT has a wide range of applications, including power system research institute, power construction company, light water reactor nuclear power station, wind power station, shipbuilding industry, natural gas pipeline, CNOOC offshore pipeline inspection, PetroChina, Yanchang oil pipeline inspection, pressure vessel inspection, aircraft maintenance, aircraft parts supplier, military metal product supplier, steel structure welding inspection, 3D printing products, etc, These industries are closely related to nondestructive testing. The development of core technology promotes the development of nondestructive testing equipment. Nowadays, nondestructive testing equipment has gradually changed from completely relying on import to independent research and development. At present, the quality of domestic equipment is not inferior to that of import. Especially in some industries that require product accuracy, product quality is particularly important.

What is the principle of nondestructive testing? Why must nondestructive testing be performed? The so-called nondestructive test, that is, non-destructive test, which uses the sound, optical, magnetic and electrical properties of materials to detect whether there are defects or non-uniformity in the tested object without damaging or affecting the performance of the tested object, so as to give the size, location, nature and quantity of defects. Compared with destructive testing, non-destructive testing has the following characteristics:

1. It is non-destructive because it will not damage the performance of the detected object during testing;

2. It is comprehensive, because the detection is non-destructive, so if necessary, 100% of the tested objects can be completely detected, which is impossible for destructive testing;

3. It is the whole process. Destructive testing is usually only applicable to the testing of raw materials, such as tension, compression, bending, etc.

It is usually used in mechanical engineering. Destructive testing is used for the manufacture of raw materials, finished products and consumables. Unless they are not ready to continue to be used, destructive testing cannot be performed, and non-destructive testing will not damage the performance of the tested object. Therefore, it can not only check the whole process of raw material manufacturing, intermediate process links and final products, but also check the equipment in use. It can be said that through nondestructive testing, the service life and performance of products in many industries have been greatly improved.

In a word, nondestructive testing technology is one of the most powerful technologies to ensure the quality of workpieces. Among them, nondestructive testing technology is mainly characterized by the technology of directly or indirectly detecting the surface or internal quality defects of the workpiece without damaging the tested workpiece and the physical structure of the workpiece. I believe that by reading the above content, you have a deeper understanding of industrial CT nondestructive testing technology. I hope this article will be helpful to you.
