Alloy 2101 (UNS S32101) is a lean duplex (ferritic-austenitic) stainless steel that has been proposed as an optimum cost solution for the umbilical tubing used to provide hydraulic power and transport production chemicals from deepwater oil and gas production facilities to remote subsea tie-back developments. Alloy 2101 does not have the inherent resistance to pitting and crevice attack in seawater environments of higher cost materials, and so needs to be protected by a layer of zinc-alloy cladding. This paper presents a comparison of zinc-clad alloy 2101 with alloy 19D (UNS S32001), which is the present material of choice for zinc-clad lean duplex stainless steel umbilical tubing and highlights some of the operational concern inherent in the introduction of a new material to deepwater service. Alloy 2101 has a composition very similar to alloy 19D, except that the chromium and nitrogen contents are slightly higher. Based upon the increase chromium and nitrogen contents, alloy 2101 has slightly improved corrosion resistance, higher strength and improved austenite reformation characteristics during welding. These improved material properties may allow zinc-clad alloy 2101 umbilical tubing to be used at deeper water depths and higher injection pressures than alloy 19D.
