Gas pipelines refer to pipelines that transport gas from mining sites or processing plants to urban gas distribution centers or industrial enterprise users, also known as gas pipelines. The use of gas pipelines to transport gas is the way to transport a large amount of gas on land. When gas is transported, the position of the pipe joint is mostly flanged butt and welded. Due to the lack of protective structure, the position of the pipe joint is easy to corrode, and it is inconvenient to judge in time when leakage occurs, and the gas flows into the air, causing waste.

Chinese Patent (Notice No. CN 208935651 U) discloses a protection device for pipe joints for gas transmission. A closed compartment structure is formed by a first baffle plate and a second baffle plate structure, which can isolate the position of the joints of the conveying pipes and avoid the The position of the pipe joint is corroded, and the pressure gauge interface is set at the same time. During the inspection, the pressure gauge can be installed at the pressure gauge interface position to determine whether there is leaking gas in the compartment. At the same time, the leaking gas will not flow directly into the air to avoid Waste, this structure requires staff to observe during inspection to know if there is any leakage. It cannot notify and deal with it in time, and it cannot cool and shrink the leaked gas to reduce the internal pressure. Instead, it is directly discharged when the pressure is too large. polluted environment.
