Tianjin as the first domestic industrial park underground integrated pipe corridor system, set water supply, heating, gas, electricity, communication and other comprehensive projects, in 2018, Tianjin pipe corridor project has been built 17.7 kilometers, is expected to 2020, the city's construction of underground integrated pipe corridor 50 to 70 kilometers. Disadvantages of underground pipe gallery 1. The wall and ground are easy to be damp and moldy. 2. Because the underground pipe gallery is often closed, flammable and harmful gases will be produced, mainly methane, carbon monoxide, hydrogen sulfide and other gases. The project provides ASD5300C, ASD5300 detector and JB-TB-ASD5100 controller.
The oil field is mainly for oil and natural gas exploration and development; The combustion of oil and crude oil in the atmosphere will produce a variety of toxic and harmful gases. Mainly nitrogen oxides, carbon monoxide, carbon dioxide, sulfur dioxide and other gases.
Steel manufacturing process will produce waste gas, mainly carbon monoxide, carbon dioxide, sulfur dioxide, nitrogen, hydrogen sulfide, hydrogen, methane and other gases, these flammable, harmful gases, pose a great threat to production safety.
Gas is one of the main hazards in metallurgical production. Its main hazards are corrosion, poison, combustion and explosion. Oxygen is used extensively in metallurgical production. Oxygen is easy to ignite, and almost all combustibles can be burned.
Winemaking is a fermentation process, through the bacterial metabolism to complete the winemaking process, mainly produces carbon dioxide gas, the wine itself is flammable, a serious threat to life and property safety.
