How deep is the natural gas pipeline buried

Update:2022-04-21   View(s):761   Keywords :How deep is the natural gas pipeline buried
The minimum covering soil thickness for the burial of underground gas pipelines shall meet the following requirements:

When buried under the roadway, it shall not be less than 0.9m;
When buried under non-vehicle roads (including sidewalks), it shall not be less than 0.6m;
When buried in a place that cannot be reached by motor vehicles, it shall not be less than 0.3m;
When buried under the paddy field, it shall not be less than 0.8m.

What is a natural gas pipeline:
Natural gas pipelines refer to pipelines that transport natural gas (including associated gas produced in oil fields) from mining sites or processing plants to urban gas distribution centers or industrial enterprise users, also known as gas pipelines. The use of natural gas pipelines to transport natural gas is the way to transport a large amount of natural gas on land. Natural gas pipelines account for about half of the total pipeline length in the world.

Features of natural gas pipelines:
1. The gas pipeline system is a continuous closed transportation system.
2. Natural gas is under pressure from transportation, and storage to user use.
3. Due to the small specific gravity of the natural gas being transported, the influence of the static pressure head is much smaller than that of the liquid. When the design height difference is less than 200 meters, the static pressure head can be ignored, and the line is almost not restricted by the longitudinal terrain.
4. There is no water hammer hazard in liquid pipelines.
5. When an accident occurs, it is very harmful and affects a wide range. Once the pipeline ruptures, the energy released is large, the tearing length is long, and the discharged natural gas will easily cause a fire if there is an open flame.
