Orangeburg pipe (also known as "fiber conduit", "bituminous fiber pipe" or "Bermico") is bituminized fiber pipe made from layers of ground wood pulp fibers compressed with and bound by a water resistant adhesive then impregnated with liquefied coal tar pitch. It was used from the 1860s through the 1970s, when it was replaced by PVC pipe for water supply and ABS pipe for drain-waste-vent (DWV) applications. The name comes from Orangeburg, New York, the town in which most Orangeburg pipe was manufactured, largely by the Fiber Conduit Company. It changed its name to the Orangeburg Manufacturing Company in 1948.
