Hakan Nickel Alloys, based in Istanbul, Turkey, is a trusted manufacturer and supplier of Super Duplex Needle Valves, designed for precise control and reliable performance in demanding industrial environments. These valves are engineered to offer exceptional strength, corrosion resistance, and durability, making them ideal for applications where accuracy and long-term reliability are critical. Manufactured to meet international standards, Super Duplex Needle Valves from Hakan Nickel Alloys provide consistent operation and high-quality performance. They are widely used in oil and gas, chemical, marine, and power industries, ensuring safe and precise flow control in harsh conditions.
Super Duplex Needle Valves are made from high-grade Super Duplex Stainless Steel, typically S32750, containing chromium, nickel, molybdenum, and nitrogen. This dual-phase structure of ferrite and austenite gives the valves outstanding corrosion resistance, high tensile and yield strength, and excellent fatigue resistance. They maintain dimensional stability and mechanical integrity under high pressure, elevated temperatures, and chemically aggressive environments. Lightweight yet strong, these valves combine toughness with long-term reliability, providing precise flow control in pipelines and systems exposed to seawater, chemicals, and other harsh industrial conditions.
