Description

Technical Field

[0001] The utility model relates to the technical field of pipeline weld quality detection, in particular to a pipeline inner and outer side point positioning device and a weld detection device. Background Technique

[0002] As an efficient and special transportation mode, pipeline transportation plays an increasingly important role in the fields of municipal gas transportation, municipal heating pipe network, municipal water supply pipeline, etc. Defects such as cracks, lack of fusion, and lack of penetration will occur during the process of pipeline welding construction. These defects will cause leakage, reduce the service life, and result in economic losses and personal injuries. Using X-ray non-destructive testing of pipelines, without damaging or affecting the service performance of the object to be detected, it can detect whether there are defects or non-uniformities in the object to be detected, and detect information such as the size, location, nature, and quantity of the defects. Discovering defects in time can reduce rework, save costs, and improve the quality of weld construction. X-ray has been widely used in pipeline detection and has achieved very good results in practice.

[0003] At the construction site, portable X-ray flaw detectors are usually used to detect the circumferential welds of large-diameter pipelines. Before detection, manual measurement is required to make marks at the inspected part of the butt weld on the inner wall of the pipeline, and then the X-ray machine is placed at the center position inside the pipeline (that is, the axis of the X-ray machine coincides with the axis of the pipeline), and the ray source window is aligned with the marked position. Then, manual measurement is used again to make marks on the outer wall of the pipeline at the points concentric with the ray source. Then, the marking tape and film are attached to the outer wall of the pipeline so that the ray source of the X-ray machine inside the pipeline and the film position on the outer wall of the pipeline are at the concentric points, and then radiography is carried out.

[0004] However, the method of manually measuring and marking the marking points on the outer wall of the pipeline often has a large working intensity and poor accuracy, resulting in low efficiency of welded steel pipe quality detection. Content of the Utility Model
