The new pipeline that was built in 2005 flows methanol through it and had a regular February snow cover on it. The other pipeline built in the 1960"s when we rode down it, had all the snow melted that was directly over the pipe. This melted snow was about 2 feet wide and went along as far as we rode. This pipeline I don"t know what runs through it. Any idea why the snow would be melted, and how an un-insulated pipeline could retain that much heat to melt snow for many miles beyond what we rode? For the curious the pipelines in my area converge into a massive pump station operated by Dominion in a little settlement called Ellisburg, PA. [Reply]   [No Email]

As said before, crude oil is heated to make for easier flowing. Had to watch in the late fall when we would sometimes depend on running on frost to pick/combine corn or plow. Frost would not happen over the pipelines till it had been colder longer. [Reply]  [No Email]

It runs from Portland ME to Montreal. It always freezes in the winter and becomes a snowmobile trail. It must be buried deeper. [Reply]  [No Email]

Other factors such as depth of burial, & type of soil used in backfilling the trench affect the heat transfer to the surface. JMHO Willie [Reply]  [No Email]
