In 1926, the Jones and Laughlin Steel Corporation built the first of three seamless tube mills at its Aliquippa Works. Expanded to include a steel conditioning area, a 30-inch round mill, two tube mills, and facilities for finishing and shipping tubes and for producing couplings, the Aliquippa Tube Works focused on seamless tube products for the oil industry. The Seamless Tube Department closed in 1982.
