On March 3, 1899, the United States Pipe and Foundry Company was incorporated consolidating 14 iron and steel foundries in 9 states. One of these foundries, the Howard-Harrison Iron Company of Bessemer, was founded in 1889. In 1911, the Dimmick Pipe Company, located in North Birmingham, became part of the company. U.S. Pipe led the industry with its introduction of the deLavaud centrifugal casting technology in 1921. The process revolutionized the U.S. pipe-making industry and remained the standard production technology over 75 years later. In 1952, U.S. Pipe merged with Sloss-Sheffield Steel and Iron Company, founded in 1881, then relocated to this site in 1953. A subsidiary of Walter Industries of Tampa, Florida, U.S. Pipe remains an industry leader as the largest producer of Ductile Iron Pipe in the United States.
