Sandvik has increased its range of heavy wall pipe available as part of its standard stock programme with the duplex stainless steel heavy wall pipes in Sandvik SAF 2205™. The standard stock range has increased to include pipe of 2-8in nominal bore in a variety of wall thicknesses and these new sizes are now available direct from Sandvik. A duplex stainless steel, Sandvik SAF 2205 offers a high resistance to stress corrosion cracking in chloride bearing environments and those containing hydrogen sulphide. It also has a high mechanical strength at roughly twice the proof strength of austenitic stainless steel with high resistance to corrosion fatigue, pitting and crevice corrosion. Used extensively in the offshore oil and gas industry, on heat exchangers and in demanding applications in the process industry, the material provides high resistance to erosion corrosion, offers design advantages as a result of its physical properties and has good weldability.
