Depth of buried gas flowline
Depth of buried gas flowline
(OP)
Hi all,
I am currently designing a buried 1.2 km gas flowline (ASME B31.8). The area is besides the province road.
Although we will put saftey signs. Probably local citizen would build a "personal" road in the future, crossing on top of the flowline.
My question is, how depth it is needed for the flowline to be buried?
A hint/reference to a standard/code would be very useful. Thanks.

RE: Depth of buried gas flowline
Beside the road, but still within the road's "Right of Way", the province or local governing body will have jurisdiction and they may want you to bury it deeper, 4ft is common, but could be more, if they will let you put it in the road's right of way. You will normally need the local government's road and transportation department's permission before locating your pipeline there.
If you are paralleling the road, but outside the right of way, you can usually go back to 3 ft clear cover.
3 ft clear cover is normally adequate for light traffic, but not for highway loads, so if you expect roads to be built on top in the future, you should watch for that type of construction activity taking place and stop and prohibit all of it and any construction within your pipeline's right of way.
You will find all the minimum burial depths listed in B31.8

In many places (like the south of Spain), the "frost line" hasn't existed for millennia, but in others it can be pretty deep. It is generally a good idea to know approximately where it is most likely to be and go deeper than that.
