ing of Super 13Cr steel (13CrS) in a Cl? environment. Regarding solid line pipes that need girth-welding process while being laid, it was reported that weldable super martensitic stainless steels were susceptible to stress corrosion cracking (SCC) at elevated tempera-tures. A new duplex stainless steel, which can be applicable even
Super duplex stainless steel and other materials, including new elastomers, will have to be evaluated and qualified for use when required. GATE, LLC has been developing testing guidelines to validate flexible pipe materials for sour service use as flowlines and risers.
This article discusses the failure investigation performed for a major operator in the Middle East on duplex stainless steel (DSS) flowline welds. The subject flowline was used intermittently since 1984 in an extreme sour service chloride-containing corrosive environment.
The name itself implies that the steel is of two phase structure. The figure-1 shows the structure of Duplex steel. Commonly considered Duplex stainless steel is Austenite and Ferrite A.F region. The different forms of Duplex stainless steel available are shown in Fig. 2. In this article DSS 22Cr 5.5 Ni 3 Mo 0.18N is considered.
