Orangeburg Pipe

Orangeburg pipe (also known as "fiber conduit") is bitumenized fiber pipe made from layers of wood pulp and pitch pressed together. It was used from the 1860s through the 1970s, when it was replaced by PVC pipe for water delivery 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. It was manufactured largely by the Fiber Conduit Company, which changed its name to the Orangeburg Manufacturing Company in 1948.
