Natural gas is trapped in underground porous rock formations, including oil field gas, gas field gas, coal bed gas, mud volcanic gas, biogenic gas, and the like, and a small amount of natural gas is also released from the coal bed. It is a high-quality fuel and chemical raw material. The natural gas is mainly used as fuel, can be used for producing carbon black, chemicals and liquefied petroleum gas, and the propane and butane produced by the natural gas are important raw materials of modern industry. Natural gas is composed mainly of gaseous low molecular hydrocarbons mixed with non-hydrocarbon gases.
The natural gas is usually transported through a pipeline, and after the natural gas pipeline joint is used for a long time, the phenomenon of gas leakage is easy to occur due to aging, and when the natural gas leakage speed is low, the natural gas leakage speed is difficult to find, but because the natural gas leakage speed has inflammability, a large potential safety hazard exists. We therefore propose a leak reminder cartridge for use at a natural gas pipeline junction.
