[0002] The integrity of oil and gas pipelines is an important factor in the safety of oil and gas transportation, and pipeline companies are very concerned about this. Pipeline corrosion or drilling and oil theft will cause pipeline integrity failure, resulting in significant economic losses, environmental and social impacts: therefore, pipelines need to be inspected regularly to promptly detect pipeline corrosion, deformation, leakage and other failures.

[0003] A scanning frame for non-destructive testing of pipelines is disclosed in the Chinese utility model patent application disclosure CN216792092U, which relates to the field of non-destructive testing technology, including a scanning frame body that can be clasped on the pipeline, and the scanning frame body has a plurality of pulley blocks that are all pressed against the pipeline, wherein two adjacent pulley blocks are jointly wound with a belt, and the track is pressed against the pipeline: the scanning frame body is also equipped with a driving structure for driving the belt transmission. The utility model is not only applicable to pipelines of any material, but also easy to install and disassemble, so that the pipeline does not require human participation during the entire inspection process, and has good guidance, but the space occupied by the device is slightly larger, and it is slightly inconvenient to use in narrow and crowded spaces. For this reason, we propose a scanning frame for non-destructive testing of pipelines. Utility Model Content
