The Seamless Tube Department at Jones and Laughlin Steel Corporation's Aliquippa Works consisted of a steel conditioning area, a 30-inch round mill, two tube mills, and facilities for finishing tubes and for producing couplings. The seamless hot mills produced high strength pipe that was used to drill oil wells, to case wells, and to transport oil and gas. The Seamless Tube Department began its decline in April 1982 and by 1989, the entire Aliquippa Works had shutdown completely."
