Boikanyo Metals is a reputable manufacturer and supplier of Super Duplex Steel Pipes, proudly based in Cape Town, South Africa. We specialize in delivering top-notch piping solutions tailored for demanding industrial applications. Super Duplex Steel is known for its remarkable corrosion resistance and impressive mechanical strength, making it a perfect fit for challenging environments like chemical, marine, and offshore settings. Our Super Duplex Steel Pipes are meticulously engineered to meet international standards, guaranteeing durability, leak-free performance, and reliability across various industries, including chemical processing, oil and gas, desalination, and power generation.
These pipes are crafted from alloys rich in chromium, nickel, molybdenum, and nitrogen, which provide exceptional resistance to pitting, crevice corrosion, and stress corrosion cracking. With a high tensile strength ranging from approximately 850 to 950 MPa, they also boast excellent fatigue resistance and mechanical stability, whether at room temperature or elevated conditions. The unique dual-phase microstructure, featuring both ferrite and austenite, combines the corrosion resistance of austenitic stainless steel with the strength of ferritic stainless steel, making them ideal for high-pressure and critical service applications.
