What are the regulations regarding the burial depth in long-distance pipelines?
Thread Content
Is there a specified burial depth for long-distance pipelines? Is it okay below the permafrost layer?
This issue is quite complex; it depends on factors such as the location, climate conditions, type of soil, the local ecological environment, and also security measures. A specific analysis is needed based on the particular circumstances, as there are significant differences
1.5M to 2M is the general requirement.
The first requirement is that it be below the depth of permafrost at the local minimum temperature; secondly, the location of the pipeline must be taken into account – if it is in an agricultural area, the maximum load that the ground surface can bear needs to be considered (mainly the weight of large motor vehicles transporting agricultural products)
Design of buried pipes in accordance with GB 50316-2000 (2008 edition) Code for Design of Industrial Metal Piping.
You can check them out; these two books are related to the field of long-distance pipelines.
It mainly depends on whether you are transporting gas or oil, as there are different regulations for each. Under normal circumstances, the thickness of the soil cover over the pipeline should not be less than 0.8 meters. The specific sections along which the pipeline will pass should be analyzed based on actual conditions. For details, see the \"National Training Manual for Design Approval Personnel of Pressure Pipelines\"
In addition to the above, when crossing rivers and gullies, it is necessary to ensure that work is carried out within the stable layer below the maximum erosion line or dredging line; this will be specified in the design drawings
We encounter such problems often as well. Thank you, I’ve learned something from this
Generally, below the permafrost layer, there will be liquid accumulation in pipes used for transporting gas; if freezing occurs in the permafrost layer, this can lead to blockages
