[0001] The utility model relates to the field of oil and gas pipelines, in particular to an iron chip remover for plugging and opening holes in oil and gas pipelines. Background Art

[0002] Oil and gas pipelines are important infrastructures for transporting oil and gas. These pipelines usually cross land, water areas, and even towns to ensure that energy can be efficiently transported from the production site to the consumption site.

[0003] During the operation of oil and gas pipelines, pipe breaks, pipe cracks, etc. often occur. At this time, it is necessary to carry out repair operations such as pipe replacement on the damaged pipeline. Before the repair, it is necessary to carry out hole-opening operations on the oil and gas pipeline. A large amount of iron chips will be generated during the hole-opening operation. Some of these iron chips are blown away by liquid or gas, and some are left at the bottom of the pipe at the hole-opening due to reasons such as pipeline shutdown. These iron chips will cause harm to the sealing surface of the plugging device and make the plugging ineffective.

[0004] Therefore, it is very necessary to invent an iron chip remover for plugging and opening holes in oil and gas pipelines. Summary of the Invention
