Business Introduction

Radiographic inspection is a method that uses a certain type of radiation to inspect the internal defects of the weld. Commonly used rays are X-rays and gamma rays. X-rays and γ-rays can pass through metal materials to varying degrees and produce photosensitivity to photographic films. Utilizing this performance, when the ray passes through the inspected weld, the intensity of the ray falling on the film is different due to the different absorption capacity of the weld defect to the ray, and the sensitivity of the film is also different, so that it can be accurate and reliable. Non-destructive display of defect shape, location and size.

5. Evaluate the film and issue a radiography pipeline inspection report.

WORKING PRINCIPLE AND MAIN STRUCTURE OF X-RAY FLAW DETECTOR

X-ray flaw detector is an instrument that uses X-rays for non-destructive testing. It can check the internal defects of the target by using the penetrability of X-rays and the attenuation characteristics in materials. X-ray flaw detector is one of the main non-destructive testing methods. It is widely used in major equipment manufacturing industries such as boilers, shipbuilding, high-speed rail, aerospace, and industrial machinery. It plays an important role in product quality control and maintenance.

Principle: The working principle of X-ray flaw detection is to use the characteristics of X-ray and attenuation in materials to find defects. X-rays are penetrating, and they can penetrate substances that visible light cannot. When X-rays pass through a sample, absorption occurs. The difference in the density and thickness of the material will cause the difference in X-ray imaging.

For example. When metal castings are in the die-casting process, the forming quality of parts often varies greatly due to different process parameters and lathe conditions. Correspondingly, the thickness and density of the formed parts will also be different. When X-rays irradiate parts, the amount of X-rays absorbed and transmitted by dense parts and defective parts of parts will also vary greatly. Therefore, the quality density and defects of parts will appear bright and dark on the see-through fluorescent screen.

Structure: Industrial X-ray flaw detectors are mainly composed of four parts: X-ray head (X-ray tube), high-voltage generator, power supply and control system, and cooling protection facilities. There are two types of mobile and portable types.

The mobile X-ray flaw detector is usually used in radiographic flaw detection in a fixed transillumination room. It has high tube voltage and tube current, which can reach 450kV and 20mA respectively, and the maximum transmission thickness is about 100mm. Its high voltage The generator, the cooling system and the X-ray machine head are installed independently, and the X-ray machine head and the high-voltage generator are connected by a high-voltage cable. The X-ray machine head can be moved in a small range through the bracket with wheels, and can also be fixed on the bracket.

It is mainly used for on-site radiographic flaw detection. The tube voltage is generally equal to less than 350kV, the tube current is 5-6mA, and the maximum thickness is about 50mm. The X-ray tube, high-voltage generator and cooling system are installed together in one casing to form-- body, referred to as the ray generator. The ray generator is connected with the controller by a low-voltage cable. * Relatively light, in addition to being used on the production site, it is often moved into a fixed transillumination room for welding inspection of small objects (such as , plates, etc.).

Non-destructive testing will not cause damage to the test object during the test, so it has many applications in industry and engineering. X-ray flaw detector is a common instrument for non-destructive testing. Understanding the relevant content of X-ray flaw detector can better carry out non-destructive testing.

Three-dimensional Drawing

Xray pipe inspection is a method of using radiation to check the internal defects of the weld. X-rays can pass through metal materials and have a light-sensitive effect on photographic film. Using this property, when the ray passes through the inspected weld, due to the different absorption capacity of the weld defect to the ray, the intensity of the ray falling on the film is not the same, and the film sensitivity is not the same, so that the shape, position and size of the defect can be accurately, reliably and non-destructively displayed.
