Steel for a large-scale commercial production of X80 (550 MPa) gas transmission linepipe was made in a scrap-based, electric arc furnace shop. Thermo-mechanical processing of skelp was completed in a Steckel mill. Successful pipe manufacture (1219 mm OD, 12.0 mm WT) and efficient field construction demonstrated that suitable steel making and processing controls can eliminate potential detrimental effects of residual chemical elements in electric steel.
