The exceptional strength of Super Duplex Steel comes from its unique composition, which includes high levels of chromium, nickel, molybdenum, and nitrogen. This balanced mix gives the tubing outstanding resistance to pitting and crevice corrosion, especially in chloride-rich environments. Mechanically, it offers a tensile strength that is approximately double that of standard austenitic stainless steels, providing remarkable durability and pressure resistance. This robust combination allows for lighter, thinner-walled tubing designs without compromising on safety or performance in demanding applications.

Super duplex steel instrumentation tubing is employed in measurement and control systems where strength and corrosion resistance are critical. Offshore and subsea oil and gas facilities utilize it for hydraulic and pneumatic instrumentation lines that are subject to seawater and elevated chloride levels. It is also employed in chemical plant services, desalination plants, and power generation systems where exposure to corrosive media is common. The tubing is well-suited for pressure gauges, flow meters, and impulse lines. Its high-pressure performance and corrosive resistance make it deliver long-term reliability in demanding instrumentation and control applications.
