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 invention relates to a tool and method for detecting a pipeline with a heat preservation layer, and belongs to the technical field of pipeline detection, the tool comprises a ray machine and an imaging plate, a mounting ring is connected between the ray machine and the imaging plate, an opening is formed in the mounting ring, and a locking piece is arranged on the opening; a positioning mechanism is arranged between the imaging plate and the ray machine, and the positioning mechanism is used for controlling rays of the ray machine and the imaging plate to be in a vertical state. The mounting ring is arranged on the pipeline wrapped with the heat preservation layer in a sleeving mode, and the opening of the mounting ring is locked through the locking piece, so that the mounting ring is reliably locked on the pipeline. And then the position between the ray machine and the imaging plate is adjusted and positioned through the positioning mechanism, so that rays of the ray machine can penetrate through the pipeline and then form an image on the imaging plate. A radiation detector is used for detecting the intensity of transmitted rays, so that the internal defects of the object can be judged.

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...
