The Inch pipelines comprised two systems, the Big Inch pipeline and the Little Big Inch pipeline. [22] The Big Inch was a 24-inch (610 mm) pipeline for crude oil; it ran from the East Texas Oil Field at Longview , Texas, to Norris City , Illinois , and on to Phoenixville , Pennsylvania, from where it branched into 20-inch-diameter (510 mm ...
Coal tar is produced through thermal destruction of coal.Its composition varies with the process and type of coal used – lignite, bituminous or anthracite. [13]Coal tar is a mixture of approximately 10,000 chemicals, of which only about 50% have been identified.
Pitch is a viscoelastic polymer which can be natural or manufactured, derived from petroleum, coal tar, [1] or plants. Pitch produced from petroleum may be called bitumen or asphalt , while plant-derived pitch, a resin , is known as rosin in its solid form.
No current AWWA standards are available for bonded coatings (zinc, coal tar epoxy, tape-wrap systems as seen on steel pipe) for ductile iron pipe, DIPRA does not endorse bonded coatings, and AWWA M41 generally views them unfavourably, recommending they be used only in conjunction with cathodic protection.

Petroleum-based sealer falls between refined tar and asphalt. There are concerns about pavement sealer polluting the environment after it is abraded from the surface of the pavement. Some states in North America have banned the use of coal tar–based sealants primarily based on United States Geological Survey studies. [1]
Coal tar can lead to health risks from long-term exposure. Before anyone knew about the contamination, kids from the area played on the site. William McKinney, a 71-year-old who grew up in the ...
Orangeburg pipe (also known as "fiber conduit", "bituminous fiber pipe" or "Bermico" or "sand pipe") is bituminized fiber pipe used in the United States. It is made from layers of ground wood pulp fibers and asbestos fibres compressed with and bound by a water resistant adhesive then impregnated with liquefied coal tar pitch .
Such a power plant would use about 2.4 million US gallons per day (0.11 m 3 /s) with a coal slurry pipeline or about 700,000 US gallons per day (2,600 m 3 /d) with a coal log pipeline. This amounts to about 2,700 or 780 acre-feet (3,330,000 or 960,000 m 3 ) per year respectively.
