In reply to the discussion: Why I think "the Pipeline" thing is a BAD idea: [View all]kentauros
(29,414 posts)Pipelines as classified as such with a range of 2" (2" to 6" are often "gathering" lines close to the sources being gathered from the ground) all the way up to (the largest I've seen) 48". They may go larger, but then you'd have to make the wall-thicknesses higher for the pressures involved, and that gets too expensive for most pipeline companies. Easier to just put in two smaller pipelines side-by-side in the same 50' easement.
If you don't mind paying a small fee to your state's resources agency, and you have a GIS program (there are free open-source programs out there) you can download full pipeline shape-files of all pipelines in your county. Buying them for the whole state might be too cost-prohibitive, so maybe search for GIS-based map-reader sites with the same info.
Try not to be too appalled by the sheer number of pipelines in and around you now
