Orifice Flanges are manufactured to replace standard pipe flanges when an orifice plate or flow nozzle is used for fluid or gas metering. Their primary function is to allow easy access to pipelines for measuring the flow rate of liquids or gases. These flanges are designed with precision and come with proper test certificates for both raw materials and finished products.
Orifice Flanges are available in various grades and materials including Stainless Steel, Carbon Steel, Duplex and Super Duplex Steel, Nickel Alloys, Monel, Copper Nickel, and Alloy Steel. This makes them suitable for high-pressure, corrosive, and industrial applications in sectors like oil & gas, petrochemical, power generation, and marine industries.
These flanges are offered in customized sizes and shapes to meet specific application requirements. Known for high tensile strength, corrosion resistance, and long-term durability, Orifice Flanges are suitable for both general and critical process piping systems.
Orifice Flanges are exported to a wide range of countries, including Qatar, Bahrain, Saudi Arabia, Indonesia, United States, Singapore, Malaysia, Turkey, UAE, Russia, Ukraine, South Africa, and Australia. Their consistent quality and performance have earned them a strong global presence across demanding industrial markets.
Manufacturing expertise includes Inconel 600 Orifice Flanges, MSS SP-44 Orifice Flanges, and Hastelloy Orifice Flanges, in addition to standard grades. These flanges are crafted to meet the stringent demands of high-pressure and corrosive environments.
