underground pipelne
(OP)
i have sveral pipelines that must pass underground of the highway
the pipelines are for different product with different diameters
1_ steam pipeline
2- saturated water
3- jet
4- fire fighting pipeline
5- oil pipeline
i don't know how to calculate safe distance between these pipelines so please if you could help me or tell me the standard

RE: underground pipelne
So. I will offer the "Ditch Diggers Rule" place the pipes a minimum of one shovel distance apart (out side to out side of pipe).
There, how does that sound?

RE: underground pipelne
is it differant between above ground and above ground pipeline
RE: underground pipelne
You might want to bury them under the road, in which case they might be several meters apart, or some companies require anywhere from 5 to 15 meters separation.
The safe distance might refer to how far apart they should be in order to not interfere with the adjacent lines, should one have to be excavated and repaired. That might depend on what equipment you would need to do that, on thier diameters, wall thicknesses, weight, how deeply they were buried, how heavy and how large an excavator, and how large a hole you would need to dig to access them.

RE: underground pipelne
i know thickness and weight and diameter but i need equation that calculate safe distance in culvert

RE: underground pipelne
I am sorry but i don't know if there is a standard for pipeline in culvert which define distance
These is my first time to construct pipeline in culvert
i need to define the distance between pipeline but i don't how cause i don't have arefrence to read
RE: underground pipelne
only i wonder what is refrence for pipeline in culvert

You wrote"
"I found the standard for buried pipelines not culvert, only i wonder what is reference for pipeline in culvert."
If you really think about it I'm sure you will realize that it makes sense to carry the same line spacing through the culvert as you have on both sides of the culvert.
If you want a different spacing just for pipes inside the culvert then you are adding extra cost to change the spacing on one side of the culvert and then again to change it back on the other side.
You should find out what the worst case spacing is then use that throughout.

Has the company that owns the hydrocarbons standards? Shell, BP or other?

RE: underground pipelne
If you must direct bury then thee should some distance between the pipes to ensure that the soil compaction is adequate for the highways loadings.
AWWA has standards that cover buried pipelines for water. Structurally no different for hydrocarbons.

RE: underground pipelne
When buried pipes are installed in parallel, principles of analysis for single pipes still apply, however soil cover must be greater than minimum. In other word, the design of parallel buried pipes requires an additional analysis for heavy surface loads (given that a common trench is used). In fact for buried parallel pipes soil slip between the pipes becomes the bottleneck for the distance calculation. Talking about 1 m or more separation then the concern becomes faded but it all depends on your pipelines diameters and soil density.
If the pipelines are in separate trenches, then embedment stability becomes a concern when a trench is excavated parallel to an existing buried flexible pipe. You should address what would happen to a buried flexible pipe when some or all the side support is removed in a parallel excavation. Ans also the existing trench stability itself is an issue to concern. At less than minimum side cover, X, side support is lost and the soil on the pipe must be supported by the pipe. If ring stiffness is inadequate, the pipe collapses.
For a detailed discussion, please refer to "Buried Pipe Design" by A. P. Moser, Steven Folkman chapter 3.

More like expert in getting others to become involved.
We've circled back to buried pipes, except they are now in culverts.
