Pipe radiographic testing protection device

The utility model relates to a pipe radiographic testing protection device. A pipe ray radiation testing protection module comprises screen plates, bow plates and crescent-shaped plates. An operator radiation protection module is formed by combination of one or more screen plates and a plurality of crescent-shaped plates. A ray source is disposed between the pipe ray radiation testing protection module and the operator radiation protection module. An operator performs ray testing on a weld joint through ray source operation lines and the ray source. By means of the device, the problem of usage of detection and protection of in-service or newly built pipe through large-dose radiation sources such as Co 60 is solved, a modular part combined protection technology is used on the basis of the prior radiation protection technology, the ray source radiation leakage dose is reduced, the actual testing device testing supervision area test value is 0.639 mu Gy/h, the radiation dose is much lower than the Chinese allowe
