Embodiment Construction
[0044] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0045] see figure 1, which shows an auxiliary device 100 for removing the anti-corrosion layer of pipeline puncture points according to an embodiment of the present invention. The auxiliary device 100 includes a housing cylinder 10 for accommodating the pipeline puncture point, at least one jack stand 20 and a sealing device 30 for isolating the pipeline perforation point, the housing cylinder 10 is covered above the pipeline perforation point, and the at least one jack stand 20 All the jack supports 20 are fixedly connected to the side of the containing cylinder 10 , and the sealing device 30 is connected to the bottom of the containing cylinder 10 .
[0046] Such as figure 2 As shown, the containing cylinder 10 includes an externa...

The invention discloses an auxiliary device for removing an anticorrosion layer of a pipeline perforation point and belongs to the technical field of safe operation of oil and gas storage and transportation. The auxiliary device comprises a containing barrel, at least one jack bracket and a sealing device, wherein the containing barrel is used for containing the pipeline perforation point, and the sealing device is used for isolating the pipeline perforation point. The containing barrel covers the upper portion of the pipeline perforation point. All the jack brackets of the at least one jack bracket are fixedly connected with the side surface of the containing barrel, and the sealing device is connected with the bottom end of the containing barrel. According to the provided auxiliary device for removing the anticorrosion layer of the pipeline perforation point, the problems that after an original oil and gas pipeline is perforated, a series of methods including pressure reduction and transportation stopping, temporary plugging through wood wedge nailing, mechanical removal of an anticorrosion layer and the like are adopted, a lot of economic losses are caused, and large potential safety hazards exist can be solved; the leakage point also can be temporarily covered under the condition that the pressure is not reduced; and meanwhile, isolation sealing is conducted on the perforation point with rubber, so that the safety can be greatly improved.
Description
technical field [0001] The invention relates to the technical field of safe operation of oil and gas storage and transportation, in particular to an auxiliary device for removing anticorrosion layers at pipeline perforation points. Background technique [0002] During the long-term operation of oil and gas pipelines, sudden perforation of oil and gas pipelines will inevitably occur. For this kind of sudden oil and gas pipeline perforation problem, the commonly used solution is to weld the plugging and repairing plate at the perforation point of the oil and gas pipeline. It can only be carried out under the condition of being removed. Among the existing methods for removing the anticorrosion layer, the more commonly used method is to temporarily block the leakage point with nailed wood wedges after the oil and gas pipeline is decompressed and stopped, and finally remove the anticorrosion layer around the leakage point by mechanical removal. anti-corrosion layer.
