Technical Field

[0001] The utility model relates to the technical field of gas pipeline welding, in particular to a gas pipeline butt joint fixing device. Background Technique

[0002] A natural gas pipeline refers to a pipeline that transports natural gas (including associated gas produced in oil fields) from the production site or treatment plant to the urban gas distribution center or industrial enterprise users, also known as a gas transmission pipeline.

[0003] When natural gas pipelines are in use, multiple sections of pipelines are often required to be connected. During the connection, the pipeline joints need to be welded to meet the butt joint. However, during the butt joint, manual handling and support are often required, causing inconvenience to personnel operation. Moreover, the joints of gas pipelines are easily affected by transportation and the environment, resulting in the attachment of dust and sundries. Therefore, it still needs to be improved.
