Wissa Pipes, a reputable manufacturer and supplier located in Kinshasa, Congo, focuses on producing top-notch Super Duplex Steel Instrumentation Tubing that’s built for high performance and resistance to corrosion. Known for its remarkable strength, toughness, and ability to withstand pitting and stress corrosion cracking, this tubing is perfect for tough industrial settings. Wissa Pipes is committed to maintaining precise manufacturing standards, ensuring reliability for applications in offshore, petrochemical, and process industries. Thanks to its well-balanced microstructure of austenite and ferrite, Super Duplex Steel Instrumentation Tubing provides outstanding durability, pressure resistance, and a long service life in demanding fluid and gas control systems.
Super Duplex Steel Instrumentation Tubing is mainly made up of chromium (24–26%), nickel (6–8%), molybdenum (3–4%), and nitrogen (0.2–0.3%), striking a perfect balance between corrosion resistance and mechanical strength. It boasts a tensile strength of about 800–900 MPa, a yield strength close to 550 MPa, and impressive elongation of 25–30%. This alloy is designed to resist chloride-induced stress corrosion, crevice corrosion, and erosion, making it ideal for challenging environments. With its high impact strength, excellent weldability, and durability, Super Duplex tubing continues to perform exceptionally well even in extreme cold and high-pressure instrumentation systems.
