Description

Technical Field

[0001] The utility model relates to the technical field of repair devices, in particular to a repair device for an anti-corrosion layer of a pipeline flange. Background Art

[0002] Pipe flanges are divided into the following six basic types according to the connection method with the pipe: flat welding flange, butt welding flange, socket welding flange, loose flange, threaded flange and integral flange. They are often used in liquid transportation. For example, some pipelines in nuclear power plants transport seawater. Coatings or rubber linings are required as anti-corrosion materials in pipelines. As the equipment operates for a longer period of time, the rubber linings and coatings of pipeline flanges age and break, and the medium corrodes the flange surface, affecting the sealing of the equipment and even affecting the operation of the equipment. Therefore, repair devices are required.

[0003] At present, the repair equipment of the anti-corrosion layer of pipeline flanges on the market is generally repaired manually by applying, which makes it difficult to ensure the flatness of the flange surface, thereby affecting the sealing of the equipment after connection. In the related technology, a support frame is set up, the support frame is fixed on the pipeline, and then the repair paint is pushed by a scraper to make the paint evenly applied. However, in actual use, the adjustment method of the support frame is relatively complicated, and the length of multiple legs needs to be adjusted in sequence so that the support frame can be fixed on pipelines of different sizes. This has certain limitations and is inconvenient for staff to use. Utility Model Content
