Tanvir Nickel Alloys stands out as a top manufacturer and supplier of Duplex Steel Check Valves in Cairo, Egypt. They offer high-quality valves that are built for exceptional strength, durability, and resistance to corrosion. These valves are meticulously engineered to guarantee reliable operation and leak-proof performance, even in the toughest industrial and marine settings. You’ll find Tanvir Nickel Alloys’ Duplex Steel Check Valves widely utilized in the oil & gas, chemical, petrochemical, and desalination sectors, where they face harsh conditions involving corrosive substances, high pressure, and extreme temperatures. This makes it essential for them to have outstanding mechanical and corrosion-resistant properties.
The Duplex Steel Check Valves are crafted from Duplex Steel S32205 or S31803, which consists of about 22% chromium, 5–6% nickel, and 3% molybdenum, with the rest being iron and a touch of nitrogen to boost strength and corrosion resistance. These valves boast impressive tensile strength (620–850 MPa), excellent yield strength, and remarkable resistance to stress corrosion cracking, pitting, and crevice corrosion. They also deliver good toughness, ductility, and reliability, even under high-pressure and corrosive conditions.
