Technical Field

[0001] The utility model relates to the technical field of natural gas pipelines, in particular to a protection device for natural gas pipelines. Background Art

[0002] The main use of natural gas is as fuel, which can be used to produce carbon black, chemical drugs and liquefied petroleum gas. Propane and butane produced from natural gas are important raw materials for modern industry.

[0003] The natural gas pipeline of an automobile door refers to the 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 the gas transmission pipeline. Using natural gas pipelines to transport natural gas is the way to transport a large amount of natural gas on land. Among the total length of pipelines in the world, natural gas pipelines account for about half.

[0004] However, since natural gas pipelines are needed in the process of natural gas transportation and the natural gas pipelines need to be connected by welding, the overall natural gas pipeline is relatively fragile only at the welded joints, and it is very easy to break at the welded joints, resulting in the leakage of natural gas and triggering major accidents.
