Steve Flanges is a reputable manufacturer and supplier located in Canberra, Australia, specializing in high-quality Duplex Steel Instrumentation Tubing. These tubes are crafted for exceptional strength, corrosion resistance, and overall performance. With a focus on precision and the use of advanced technology, Steve Flanges ensures that each tube boasts remarkable dimensional accuracy, smooth internal surfaces, and impressive resistance to pressure and temperature fluctuations. They offer a wide range of Duplex Steel Instrumentation Tubing in various grades, sizes, and finishes that comply with international standards. These tubes are perfect for critical instrumentation and control systems, finding extensive use in industries like oil and gas, petrochemical, marine, and power generation.
The composition of Duplex Steel Instrumentation Tubing primarily includes iron, chromium (21–23%), nickel (4.5–6.5%), molybdenum (2.5–3.5%), and nitrogen. This unique dual-phase structure merges the high strength of ferritic steel with the toughness and ductility of austenitic steel. The tubing showcases a tensile strength ranging from 700–950 MPa and a yield strength of about 450–550 MPa. It also offers excellent resistance to chloride stress corrosion cracking, pitting, and crevice corrosion. Thanks to its balanced microstructure, it provides outstanding stability, weldability, and fatigue resistance, even under high-pressure and high-temperature conditions.
