[0002] Carbon dioxide is a type of industrial gas. A carbon dioxide transmission pipeline is a pipeline system specifically used to transport carbon dioxide gas. It is generally used in industries such as beverages, food, and chemicals, as well as greenhouses, oil wells, and mining. The main function of a carbon dioxide transmission pipeline is to transport carbon dioxide from the production site to the use site to ensure that carbon dioxide can be used safely and efficiently.
[0003] However, the existing transmission pipeline has the following disadvantages:
[0004] (1) The existing pipelines have weak sealing functions. When in use, multiple pipelines are connected to each other, which easily creates gaps during the connection process. Carbon dioxide is a greenhouse gas. When leakage occurs at the connection, it is easy to pollute the surrounding air environment.

General pipelines do not have these properties. When used for too long, the pipelines are prone to rupture and cracks, causing gas leakage, which can easily reduce the service life of the pipelines.
