capable of human construction material transport process pipeline network 2021-04-05T16:38:47.162Z A human construction which is used to transport a material which is primarily composed of liquid or gas through a system of pipes. Getting an example of use could be helpful. Are some environmental samples collected from the outside of a pipe or its fittings? Or taken from inside the pipe? Removing "transport" from the label may make the labels of sublasses more readable. However, "pipeline" alone could mean several unrelated things, like software pipelines. https://www.eia.gov/energyexplained/natural-gas/natural-gas-pipelines.php uses the term "pipeline network". ALSO could this be a transport feature? Xref https://github.com/EnvironmentOntology/envo/issues/1111. Pipeline networks typically materials either from 1) a production area to a market area for consumption, 2) a production area to an area for waste disposal.
