Bhavesh Tube Fittings is a renowned manufacturer and supplier based in Dubai, UAE, specializing in high-quality tube fittings for various industrial applications. Committed to excellence, we offer a comprehensive range of Duplex Steel Tube Fittings known for their superior corrosion resistance, high strength, and durability. Serving industries such as oil and gas, petrochemical, and marine, we ensure top-notch products that meet international standards, delivering reliability and long-lasting performance across critical environments.
Duplex steel tube fittings typically consist of a blend of austenitic and ferritic stainless steels, primarily featuring around 22% chromium, 5% nickel, 3% molybdenum, and nitrogen. This composition provides excellent mechanical properties, including high tensile strength (up to 550 MPa), good ductility, and resistance to stress corrosion cracking. The advantages of duplex steel tube fittings include superior corrosion resistance, high strength-to-weight ratio, enhanced toughness, excellent weldability, and cost-effectiveness in demanding environments, making them ideal for applications in oil and gas, chemical processing, and marine industries.
