Aman Pipes and Tubes, a reputable manufacturer and supplier based in Hyderabad, India, proudly offers top-notch Duplex Steel Seamless Pipes that blend impressive strength with outstanding corrosion resistance. Crafted with precision, these pipes are perfect for tough environments where both mechanical performance and resistance to stress corrosion cracking are vital. The unique dual-phase microstructure of duplex steel—comprising ferrite and austenite—provides exceptional toughness, weldability, and durability. Aman guarantees that all duplex seamless pipes adhere to international quality standards, ensuring optimal performance in demanding sectors like oil & gas, petrochemicals, marine, and power generation, where reliability and longevity are key.
Duplex Steel Seamless Pipes generally contain about 22–25% Chromium, 5–8% Nickel, and 3–5% Molybdenum, along with Nitrogen and a balance of Iron. This blend offers remarkable resistance to pitting, crevice corrosion, and stress corrosion cracking. Their mechanical properties boast high yield strength (around 450–620 MPa), tensile strength (approximately 620–800 MPa), and good elongation (about 25–30%). The duplex structure provides greater strength compared to standard austenitic stainless steels while still maintaining good toughness. The seamless manufacturing process ensures consistent wall thickness and improved pressure tolerance, making these pipes ideal for high-stress and high-temperature applications.
