Description

Technical Field

[0001] The utility model relates to the technical field of flaw detectors, in particular to a seamless steel pipe flaw detector. Background Art

[0002] Seamless steel pipes have a hollow cross-section and are widely used as pipelines for conveying fluids, such as oil, natural gas, coal gas, water, steam, and certain solid materials. In order to ensure quality during the production process of seamless steel pipes, they need to be inspected by visual inspection, water pressure, or radiography. However, the current clamping stability during seamless steel pipe inspection is poor, which can easily affect the inspection results.

[0003] In order to solve the above problems, the prior art proposes a seamless steel pipe flaw detection device with patent publication number CN219302442U. By setting a clamping assembly, the plug rod is pulled out, and the handle is turned to drive the threaded rod to rotate, so that the threaded block drives the first mounting plate to move right, and the seamless steel pipe is placed in the left chuck. Then, the handle is reversed, so that the first mounting plate drives the right chuck to move left until it is in contact with the right side of the seamless steel pipe, so that the seamless steel pipe can be stably clamped. Although it is convenient for stably clamping the seamless steel pipe, when it is necessary to perform flaw detection on other positions of the seamless steel pipe, the seamless steel pipe needs to be disassembled, turned over and re-fixed before the flaw detection is performed. The time for disassembly, turning over and fixing is long, which can easily reduce the flaw detection efficiency of the seamless steel pipe. Utility Model Content
