Veer Flanges stands out as a leading manufacturer and supplier of Super Duplex Steel Orifice Flanges in Kolkata, India. We provide high-performance flanges that are specifically designed for accurate measurement of fluid and gas flow in critical process lines. Our flanges come equipped with orifice plates and pressure tap connections, making them perfect for flow monitoring and control. Made from corrosion-resistant Super Duplex Steel, these orifice flanges boast exceptional durability, strength, and performance, even in high-pressure, high-temperature, and corrosive environments. At Veer Flanges, we offer customized orifice flange assemblies that meet international standards like ASTM, ASME, and ANSI, catering to industries such as oil & gas, petrochemical, and water treatment.
Super Duplex Steel Orifice Flanges are made up of 24–26% chromium, 6–8% nickel, 3–5% molybdenum, and 0.2–0.3% nitrogen, along with iron and trace elements that boost corrosion resistance. Their unique austenitic-ferritic dual-phase structure provides impressive mechanical strength and excellent resistance to stress corrosion. These flanges have a tensile strength of ≥800 MPa, yield strength of ≥550 MPa, and an elongation of 25%. The toughness and durability of the material ensure reliability in extreme service conditions, including high-pressure flow systems that deal with aggressive chemicals, chloride-rich environments, and fluctuating temperature cycles.
Veer Flanges, a premier supplier in Kolkata, India, specializes in high-quality Super Duplex Steel Orifice Flanges, valued for their exceptional durability, corrosion resistance, precise engineering, and suitability across diverse industrial applications.
