Abstract. Since 1994, IPSCO has produced over 180,000 tons of X80 linepipe. This steel has been produced using a unique combination of electric arc furnace (EAF) melting, controlled rolling on a Steckel mill and spiral pipe-forming with double submerged arc (DSAW) welding. Each of these technologies presents unique challenges for the …
