Veer Flanges is a reputable manufacturer and supplier of Stainless Steel Orifice Flanges based in Kolkata, India. We specialize in providing precision-engineered solutions that ensure accurate flow measurement in piping systems. Our orifice flanges are specifically designed to accommodate orifice plates, which play a crucial role in measuring the flow rates of liquids and gases. Each flange is equipped with pressure tap holes for straightforward pressure drop measurement and is crafted from high-quality stainless steel grades like 304, 316, 321, and 347. Adhering to ASME B16.36, ASME B16.5, and ASTM A182 standards, our orifice flanges are essential for various applications in the oil & gas, chemical, power, and process industries.
Our Stainless Steel Orifice Flanges are made from top-notch austenitic stainless steel grades, including 304, 316, and 321. These materials contain 18–20% chromium, 8–12% nickel, and up to 3% molybdenum in the case of 316, enhancing their resistance to pitting. With tensile strengths ranging from 485–620 MPa, yield strengths of 170–310 MPa, and elongation rates of 30–35%, these flanges are built to last. Their excellent corrosion resistance, mechanical strength, and dimensional stability make them perfect for high-accuracy pressure and flow measurements, ensuring reliable performance even in challenging environments.

Stainless Steel Orifice Flanges are primarily utilized in flow metering and control applications, particularly where precise fluid flow measurement is essential. You’ll find them commonly installed in refineries, chemical plants, power stations, oil & gas pipelines, and pharmaceutical processing facilities. These flanges work in tandem with orifice plates, flow nozzles, and differential pressure transmitters to accurately measure the volumetric or mass flow rates of gases, steam, and liquids. The integrated pressure tap holes facilitate precise detection of pressure drops across the orifice plate, making them vital components in critical flow measurement systems.
