Tanvir Nickel Alloys, based in Cairo, Egypt, stands out as a top manufacturer and supplier of high-quality Duplex Steel 2205 Pipes. These pipes are celebrated for their remarkable strength, durability, and resistance to corrosion. With a focus on duplex stainless steels, Tanvir ensures that their pipes meet rigorous industrial standards, guaranteeing reliable performance even in the toughest environments. Designed to endure harsh chemical, marine, and high-pressure conditions, Duplex Steel 2205 Pipes are crafted using advanced manufacturing techniques and stringent quality control measures. This commitment results in pipes that offer long-lasting, high-performance solutions for critical piping systems, ensuring safe and dependable flow management across various sectors, including chemical processing, oil and gas, marine, and industrial applications.
The composition of Duplex Steel 2205 Pipes includes around 22% chromium, 5–6% nickel, 3% molybdenum, and the remainder is iron, with small amounts of nitrogen added to boost strength and corrosion resistance. These pipes are known for their impressive mechanical properties, showcasing high tensile and yield strength, excellent toughness, and outstanding resistance to stress corrosion cracking, pitting, and crevice corrosion. Thanks to their duplex microstructure, they offer a well-balanced mix of ferritic and austenitic characteristics, ensuring durability and stability under high pressure, temperature changes, and aggressive chemical conditions. This makes them perfect for critical industrial piping systems.
