[0002] A gas pipeline refers to a pipeline system used to transport natural gas, liquefied petroleum gas and other gases. It is an important channel connecting towns or cities with gas production or storage locations, and is used to transport gas to residents, industrial and commercial users. Some gas pipelines are erected at high places, and the periphery of the gas pipeline needs to be cleaned regularly to prevent dust and dirt on the periphery of the gas pipeline from causing risks such as fire and explosion.
