The gas pipelines in the underground pipeline network provide residents with a natural and clean fuel. However, as the gas pipelines age and the joints of the pipelines corrode, they may cause gas leaks. Due to the flammable, explosive and toxic characteristics of city gas, once it leaks, it is very easy to cause poisoning, fire, explosion and other serious accidents, resulting in loss of life and property.
