Aman Pipes and Tubes, a reputable manufacturer and supplier located in Hyderabad, India, specializes in high-quality Duplex Steel Instrumentation Tubing. This tubing is specifically crafted for critical measurement and control systems in tough industrial settings. With a focus on precision and reliability, these tubes boast a balanced duplex microstructure of austenite and ferrite, which provides outstanding mechanical strength and remarkable resistance to stress corrosion cracking, pitting, and crevice corrosion. Perfect for high-pressure and aggressive media conditions, Aman’s Duplex Steel tubing meets international standards and is suitable for both onshore and offshore applications across various sectors, including oil & gas, petrochemical, power generation, and marine industries.
Duplex Steel Instrumentation Tubing generally consists of 22–25% Chromium, 5–8% Nickel, 3–5% Molybdenum, along with a carefully controlled amount of Nitrogen. This unique blend gives it excellent resistance to localized corrosion, particularly in environments rich in chlorides and acids. Its mechanical properties include a high yield strength of around 450–620 MPa, tensile strength of approximately 620–800 MPa, and an elongation of about 25–30%. The duplex structure ensures reliable performance under pressure while effectively resisting stress corrosion cracking. The tubing also features smooth internal surfaces, consistent wall thickness, and outstanding dimensional tolerances, making it perfect for precise instrumentation and control applications.
