Coal gas is using coal as the gas containing combustible component made from Raw material processing.According to processing method, gas characteristic and
Purposes is divided into：What coal gasification obtained is water-gas, semiwater gas, air gas (or producer gas).
The calorific capacity of these coal gas is relatively low, therefore is referred to as low-heat value gas again；The gas that coking obtains in dry distillation of coal method claims
For coke-stove gas, blast furnace gas.Belong to middle calorific value of gas, makees domestic fuel for city.Carbon monoxide in coal gas and hydrogen
It is important industrial chemicals.
Coal gas is applied very extensive in our life, is cooked, is cooked, heating up water all be unable to do without.But coal gas is in band
While facility to us, various hazardous accidents are will also result in.It is exactly gas poisoning known to us the most, seriously
Gas leak caused by fire possibly even again at large-scale the condition of a disaster.
Buried gas piping is encountered when if steel plant area constructing road or enlarging being constructed at present, due to gas piping side
In the presence of the restrictive conditions such as hot work welding are unable to, the mode of generally use is to create a gas piping to change existing pipeline
Line, and newly-built pipeline engineering input is very big, and in order to which steel normally produces, gas pipe is carried out when being typically employed in steel plant's overhaul
Road is relocated, and the period is longer, and this mode influences the road construction duration also bigger.
Therefore, we are badly in need of designing a kind of protection structure of underground gas pipeline and solve the above problems.
