Technical Field

[0001] The utility model relates to the technical field of natural gas pipelines, in particular to a non-destructive detection fixing fixture device for natural gas pipelines. Background Art

[0002] A natural gas pipeline is a pipeline that transports natural gas (including associated gas produced by oil fields) from the extraction site or processing plant to the city gas distribution center or industrial enterprise users. It is also called a gas transmission pipeline. Using natural gas pipelines to transport natural gas is a way to transport a large amount of natural gas on land. Natural gas pipelines account for about half of the total length of pipelines in the world.

When testing the natural gas pipelines, the back side of the natural gas pipelines is not easy to test, and it needs to be turned over manually, which is not convenient for testing.
