[0002] The function of the plug is to block the unnecessary openings in the pipeline to play a sealing role. It has the same nature as blind plates, heads and pipe caps. The plug, also known as pipe caps, cover heads, pipe covers, and blind heads, is a pipe fitting installed on the external threads of the pipe end to cover the pipe. It is used to close the pipeline and has the same function as a pipe plug. It can be directly screwed on the pipe without the need for other pipe fittings. The plug includes convex plugs, cone shells, reducers, flat covers and tightening mouth designs.

[0003] For example, the public document with application number CN20211357887.6 discloses a welding plug, which is used in conjunction with a plug unit, a steel pipe, a weld, a connecting pipe, a sealing body, a connecting rod and an inflation component. By inflating the sealing airbag to make the sealing airbag expand, a fixed connection and a sealed connection with the steel pipe are achieved, which is convenient for operation and prevents air from mixing into the protective gas. However, the use of this new type of plug is not convenient for disassembly and installation, which increases the burden on the staff.
