[0002] A natural gas pipeline refers to a pipeline that transports natural gas (including associated gas produced in oil fields) from the mining site or processing plant to the urban gas distribution center or industrial enterprise users. It is also called a gas transmission pipeline. Using a natural gas pipeline to transport natural gas is a way to transport natural gas in large quantities on land. Natural gas pipelines have a very long history in China. At the beginning, my country used wood and bamboo to transport it. Around 1600, it began to use pipelines for transportation. It is very convenient and fast. It is currently the only way to transport natural gas in large quantities on land. At the same time, according to various data, natural gas pipelines account for about half of the total length of pipelines in the world.
[0003] However, it still has some shortcomings. For example, if there is an open flame around the existing natural gas pipeline, it will explode and cause a fire. When burying the natural gas pipeline, there is no protective pipe and if you are not careful, the pressure-bearing capacity is not good and the natural gas pipeline will be damaged. When installing the natural gas pipeline, if the interface is loose, it will cause leakage and poor sealing. Employees need to check and maintain it regularly, which consumes their capacity.
