[0002] Pipe fittings are open at both ends and have a hollow, concentric cross-section. They are usually circular, but non-circular shaped pipes are also available. Common types include cast iron pipes, steel pipes, non-ferrous metal pipes, non-metallic pipes, and plastic pipes. They can be used for pipelines, thermal equipment, machinery industry, oil and geological drilling, containers, chemical industry, and special applications. When pipe fittings are connected by welding, they are classified into butt welds, fillet welds, plug welds, and electric riveting welds, depending on the shape of the weld metal and the relative positions of the weldments.

[0003] After welding, the weld seams of pipe fittings need to be radiographically inspected using an inspection device before use to ensure weld quality and guarantee strength.

This results in low inspection efficiency, frequent pipe movement, and a large workload. Therefore, a radiographic inspection device for pipe welds is needed to improve upon these issues.

A telescopic rod 304 is installed on the side of the second rotating rod 302. The output end of the telescopic rod 304 is fixedly connected to a second abutment plate 305. The rotation mechanism composed of rotating wheel 203, belt 204 and transmission wheel 205 is driven by the flipping motor 202 to rotate, thereby driving the pipe body 306 pressed against by the first abutment plate 208 to rotate. This allows the pipe body 306 to be flipped, achieving the purpose of comprehensive inspection and ensuring the inspection range. The transmission mechanism composed of rotating wheel 203, belt 204 and transmission wheel 205 has the advantages of safety, simplicity and low cost.

[0029] The top of the support frame 101 is fixedly connected to a protective box 209. A rotating wheel 203, a belt 204, and a transmission wheel 205 are disposed inside the protective box 209.
