    Oil and Gas Industry Gets N’GENIUS Development

    A ground-breaking new series of high-strength austenitic stainless steels have been developed that will transform how materials are specified and utilized across the oil and gas sector.

    The N’GENIUS SeriesTM represents the total reinvention of conventional austenitic stainless steels and has been specifically developed to out-perform, supersede and supplement the majority of existing grades in the 300 Series, the corrosion-resistant alloy (CRA) line pipe grades currently available for selection in the API Specification 5LC and the DNV-ST-F101 standard, plus the CRA Oil Country Tubular Goods (OCTG) in the API Specification 5CT for Casing and Tubing.

    Dr. C.V. Roscoe, the inventor of the original 25Cr super-duplex stainless steel and CEO of N’GENIUS Materials Technology, explained:

    “The extensive range of alloy types, variants, and grades in the N’GENIUS SeriesTM of High Strength Austenitic Stainless Steels have strength properties equivalent to duplex and super duplex stainless steels, ductility and toughness levels normally associated with conventional austenitic stainless steels but with far superior corrosion resistance to suit all major oil and gas projects.

    “The engineering significance of the N’GENIUS SeriesTM for onshore and offshore CRA pipeline projects, subsea production systems, and OCTG for CRA casing and tubing is truly astounding.

    “Also design engineers considering the best way to develop major offshore projects utilizing potential combinations of Platforms, FPSO vessels, or FLNG vessels can take advantage of the high strength properties of the N’GENIUS SeriesTM to reduce topside weight for all the piping systems, modules, engineered products, and fabricated equipment. This enables the engineering design and construction of the projects to be optimized thus leading to an overall reduction in the costs of the projects.”

    What makes N’GENIUS so ingenious?

    Patent protected in 30 countries globally, the N’GENIUS SeriesTM provides a unique combination of unprecedented strength compared to conventional 300 Series grades of austenitic stainless steels, vastly improved corrosion resistance, and excellent toughness at sub-zero temperatures.

    These and other key engineering design characteristics will allow an infinite range of product forms and ancillary equipment to be designed, specified, manufactured, and supplied with the objective of reducing wall thicknesses and overall size, using less material, and producing lighter products. This makes products easier to handle and transport to the site, leading to weight savings, an overall reduction in construction and project costs, and – perhaps most importantly – contributing to lower carbon emissions and a greener world.

    The superior corrosion resistance of the N’GENIUS SeriesTM will also improve the through-life costs and extend the service life and environmental sustainability of these projects.

    No more compromising on materials

    The unique combination of mechanical strength and corrosion resistance properties of the N’GENIUS SeriesTM will fundamentally change the materials selection philosophy for oil and gas industry projects throughout the world, including all major upstream, midstream, and downstream developments.

    At present, there isn’t a particular CRA pipeline material that totally satisfies all the requirements of design engineers, process engineers, corrosion specialists, and project engineers for major CRA pipeline projects in a wide range of service conditions including high pressure, high temperature (HPHT) developments, and process media environments containing various levels of Chlorides, CO2, H2S, and other constituents. Until now.

    Total system capability

    In terms of oil and gas production system design, the N’GENIUS SeriesTM has been developed to be the total system material solution. A vast array of wrought and cast products and equipment can be manufactured and supplied in the N’GENIUS SeriesTM for onshore and offshore oil and gas production systems.

    Subsea umbilicals, catenary risers and flowlines, manifolds, subsea bundles, wellheads, fittings, flanges, compact flanges, hub connectors, and engineered products such as pumps and valves are among these products and equipment. Our fabricated products such as offshore topside systems including spools, modules, static risers, process piping systems, seawater cooling systems, firewater systems, filtration systems, heat exchangers, and various ancillary equipment including tanks, vessels, and structures.

    A pipeline technology without limits

    The N’GENIUS SeriesTM of CRA line pipe grades, which can be available in both seamless and welded product forms, will provide a virtually unlimited choice of high-strength austenitic stainless steels for industry specialists to select from and help satisfy the growing demand for high-performance stainless steels that are stronger, last longer and are better for the planet.

    Specifically, the N’GENIUS SeriesTM of CRA line pipe grades will address the need for a much wider selection of CRA line pipe materials that are suitable in a wide range of service conditions and process media environments for all types of onshore projects and offshore projects in shallow, deep and ultra-deep water that can be installed using the various installation methods including S-lay, J-lay, Reel-lay, and subsea Bundle installation techniques.

    The ideal material choice for OCTG

    Reaching new reserves, operating in challenging service conditions and exposure to increasingly aggressive process media puts material choice for OCTG into sharp focus and further highlights the enormous benefits of the N’GENIUS SeriesTM.

    Perfectly suited for OCTG casing and tubing, the high strength of the N’GENIUS SeriesTM helps overcome the dilemmas caused by elevated temperatures, high pressures, and higher mechanical loads, whilst its improved corrosion resistance provides a robust defense even in harsh process media environments containing various levels of Chlorides, CO2, H2S, and other constituents.

    The N’GENIUS SeriesTM also ensures the very best resistance to hydrogen embrittlement and, in particular, stress corrosion cracking (SCC) in aggressive media environments which can often be a major obstacle for OCTG.

    For design engineers – where the long and safe operation of wells is key – the availability of durable, pressure and corrosion-resistant downhole casing and production tubing is essential, and the alloy types, variants, and grades of the N’GENIUS SeriesTM provide the answer.

    The N’GENIUS way

    To assist engineers at the conceptual design stage, pre-FEED and FEED stages and detailed engineering design stages of the materials selection and specification process, Material Data Sheets (MDS) have been formulated for a wide range of product types to establish the minimum criteria for the manufacture, inspection, testing, and control in accordance with International Codes, Standards and Specifications for each Alloy Type, Variant and Grade in the N’GENIUS SeriesTM.

    The N’GENIUS SeriesTM is available to be manufactured under license by premier manufacturers of stainless steel products. Engineers interested in discovering more about the N’GENIUS SeriesTM can visit www.ngeniusmaterials.com or its sister company United Pipelines (www.unitedpipelines.com).
