Technical Field
[0001] The utility model relates to the technical field of seamless steel pipe inspection, in particular to an automatic turning device for inspecting stainless steel seamless steel pipes. Background Art
[0002] Seamless steel pipe is a hollow, seamless steel material in round, square, or rectangular shapes. It is made from steel ingots or solid billets, perforated to form a rough tube, and then hot-rolled, cold-rolled, or cold-drawn. With its hollow cross-section, seamless steel pipe is widely used as a fluid transport pipe and is one of the most widely used materials for machining. During the manufacturing process, slag inclusions and loose material often cause defects such as cracks or folds on the surface and inside of the formed steel pipe, posing a safety hazard. Therefore, ultrasonic flaw detection is necessary.
[0003] The inspection of seamless steel pipes requires rotating the seamless steel pipes to cooperate with ultrasonic probe inspection. However, most inspection devices for seamless steel pipes can only be used for seamless steel pipes of a single specification and cannot be adapted to seamless steel pipes of different sizes. In addition, dust and impurities on the outside of the seamless steel pipes can easily affect the detection accuracy of the ultrasonic probe and affect the actual inspection results.
