Wai Nickel Alloys is a reputable manufacturer and supplier located in Naypyidaw, Myanmar, specializing in top-notch Duplex Steel 2205 Pipes. These pipes are celebrated for their remarkable strength, resistance to corrosion, and long-lasting durability, making them perfect for tough industrial settings. At Wai Nickel Alloys, precision in manufacturing and adherence to international standards are priorities, ensuring that their pipes perform exceptionally well even under extreme pressure and temperature conditions. Industries like oil and gas, chemical processing, marine engineering, and desalination rely on Duplex Steel 2205 Pipes for their outstanding resistance to stress corrosion and pitting.
The composition of Duplex Steel 2205 Pipes features a well-balanced austenitic-ferritic microstructure, typically made up of chromium (22%), nickel (5–6%), molybdenum (3%), and nitrogen. This unique blend results in impressive tensile strength (around 620–880 MPa) and yield strength (approximately 450 MPa), along with excellent toughness and hardness. Thanks to their dual-phase structure, these pipes offer exceptional resistance to chloride-induced corrosion, crevice corrosion, and intergranular attack, ensuring they stand the test of time in demanding environments.
