Embodiment Construction

[0061] The following is attached Figure 1-8 The application is described in further detail.

[0062] The embodiment of the present application discloses a digital ray detection tool for a pipeline with an insulation layer. refer to figure 1 , a kind of inspection tooling and detection method for pipelines with insulation layers, comprising an installation ring 3 and a ray machine 1 and an imaging plate 2 arranged at both ends of the diameter direction of the installation ring 3, when performing digital ray detection on a pipeline with an insulation layer 6, the The mounting ring 3 is fixed on the X-ray machine 1 and the imaging board 2, so that a vertical state is formed between the radiation source on the X-ray machine 1 and the imaging board 2, so as to improve detection accuracy.

[0063] refer to figure 2 , the mounting ring 3 is provided with an opening 31, and when the weld seam on the pipeline 6 with the insulation layer is detected, the installation ring 3 is slee...

Abstract

The application relates to a pipeline detection tool and detection method with an insulating layer, which belongs to the technical field of pipeline detection, and includes a ray machine and an imaging board, and a mounting ring is connected between the ray machine and the imaging board, and the mounting ring An opening is provided on the opening, and a locking member is provided on the opening; a positioning mechanism is provided between the imaging board and the X-ray machine, and the positioning mechanism is used to control the vertical position between the radiation of the X-ray machine and the imaging board. state. Set the installation ring on the pipe wrapped with the insulation layer, and lock the opening of the installation ring through the locking piece, so that the installation ring can be locked on the pipe reliably. Then the position between the X-ray machine and the imaging board is adjusted and positioned by the positioning mechanism, so that the radiation of the X-ray machine can pass through the pipeline, and then form an image on the imaging board. The defects inside the object can be judged by using the radiation detector to detect the intensity of the transmitted rays.

Description

technical field [0001] The present application relates to the technical field of pipeline detection, in particular to a detection tool and detection method for a pipeline with an insulation layer. Background technique [0002] At present, industrial pipelines are welded by multiple pipelines. In order to ensure the welding quality, it is necessary to detect the connection weld between every two pipelines. [0003] In related technologies, when industrial pipelines such as steam pipelines or some liquid pipelines are in use, a thick insulation layer needs to be wrapped on the pipelines. For safety, the industrial pipelines need to be inspected regularly during use. Generally, the imaging plate type X-ray pipeline detection technology is used. When the pipeline is inspected, the imaging plate is first bound to the pipeline with a strap, and then the ray source is penetrated on the pipeline, and the rays are vertically set on the imaging plate. When the intensity is uniform Wh...
