[0003] A search revealed an existing patent (publication number: CN215415391U) that discloses a pipeline nondestructive testing device comprising a support mechanism, a bearing mechanism disposed on the support mechanism, and a bearing assembly for securing a probe. The bearing assembly rotates coaxially with the pipeline, and a drive mechanism is disposed on the support mechanism for driving the bearing assembly. This patent facilitates circumferential testing of annular welds in pipelines.

[0004] However, in the process of performing nondestructive testing on chemical engineering pipelines, the length and position of the existing nondestructive testing devices for chemical engineering pipelines are fixed. Therefore, when different positions of the pipeline need to be tested, the staff needs to manually adjust the position of the testing device, which is quite troublesome. Moreover, when testing bent pipes, the position of the testing device needs to be repeatedly changed and adjusted, which is prone to errors and greatly reduces the practicality of the testing device.

[0005] Therefore, in order to solve the above problems, a non-destructive testing device for pipelines in chemical engineering is proposed. Utility Model Content
