ATI Allegheny Ludlum, an Allegheny Technologies Inc. company, has announced that its proprietary alloy was used in a subsea flow line system for the Kikeh Field Development Project, offshore Sabah, East Malaysia. Allegheny Ludlum supplied over 1.2 million pounds of its new proprietary AL 2003™lean duplex alloy to Wellstream International Ltd, located in Newcastle, UK, who manufactured flexible pipe for this project. AL 2003 lean duplex alloy is an economic alternative to higher nickel-bearing 300 Series stainless steels and the conventional 2205 duplex alloy. The Kikeh Field Development Project consists of 22km of various flow line systems (production, water injection, and gas export) operating in water depths of over 1200m. About 15.5km of flow line systems were made with the AL 2003 lean duplex alloy.
