AI Technical Summary
In the leakage radiation test, the pipe body is prone to positional movement or inclination during the detection process, which affects the effectiveness and accuracy of the radiation detection. During the detection process, the position of the pipe body needs to be adjusted repeatedly, which increases the detection time and may introduce errors.
A leak-ray testing tooling is designed, including a base plate, two support frames and limiting components. The support frame consists of a support plate, a restriction plate and a rotary locking member. The limiting assembly consists of a cross rod, a support rod and a clamp. These components are used to position and limit the pipe body to ensure its stability during the inspection process.
Through this tooling, the pipe body can be accurately positioned and limited before testing, ensuring the effectiveness and accuracy of ray detection, reducing detection time and reducing errors. At the same time, the rotation and height adjustment of the pipe body becomes more convenient, which improves the flexibility and accuracy of detection.

[0002] In the field of industrial non-destructive testing, radiation leakage testing is mainly carried out on equipment or components that may cause radiation leakage, especially on pipes containing radioactive sources. If the pipe or the system connected to it contains radioactive sources (such as X-ray tubes, gamma-ray sources, etc.), then these pipes need to be strictly tested for radiation leakage during manufacturing, installation, use or maintenance to ensure that radioactive substances will not leak into the environment and cause harm to personnel and equipment.
