Duplex stainless steel (DSS) and super duplex stainless steel (SDSS) are extensively used in various product forms for critical applications such as pipelines, flow lines, process piping, valves, heat exchanger tubes, fittings etc. across onshore Oil & Gas production facilities. DSS materials are selected where carbon steel (CS) and austenitic stainless steel (ASS) materials are not able to provide required corrosion resistance to meet the design life cycle. Petroleum Development Oman (PDO) has over two decades of experience in procurement and use of DSS materials in their production facilities (most of them successful in operation / design life). This paper reflects two objectives: first the end user perspective on quality assurance and procurement & construction challenges associated with DSS materials and second this paper highlights the operational best practices to ensure technical integrity and meet intended design life cycle of DSS components.

Key words: Duplex stainless steel (DSS), Quality assurance, integrity, Oil & Gas, Gas production flowlines.
