Ashraf Nickel Alloys stands out as a top manufacturer and supplier of Super Duplex Needle Valves in Riyadh, Saudi Arabia. They specialize in precision-engineered valves that ensure accurate flow control and perform exceptionally well under high pressure. Crafted from Super Duplex stainless steel grades S32750 and S32760, these needle valves boast remarkable resistance to corrosion, pitting, and stress corrosion cracking. Known for their durability and reliability, they’re a go-to choice in industries where precise flow regulation and shut-off capabilities are crucial. Built to comply with ASTM, ASME, and international quality standards, these valves promise tight sealing, high tensile strength, and a long service life, even in tough chemical and marine settings.
Super Duplex Needle Valves are crafted from a cutting-edge duplex alloy that features around 25% chromium, 7% nickel, 4% molybdenum, and nitrogen, giving them double the strength of standard stainless steel. They deliver a tensile strength ranging from 800 to 1,000 MPa and a yield strength of about 550 MPa, ensuring they can handle high-pressure situations with ease. With outstanding resistance to chlorides, they excel in seawater, brine, and harsh chemical environments. These valves maintain their integrity in temperatures from -50°C to +300°C, resisting erosion, wear, and fatigue. Super Duplex Needle Valves are designed for industries that demand maximum precision, exceptional corrosion resistance, and a long operational life in challenging applications.
