Precision-Engineered Orifice Flanges Manufacturer & Supplier in India
Orifice Flanges are specialized flanges designed to measure the flow rate of liquids or gases in a piping system. These flanges are used with an orifice plate and pressure taps to calculate flow using differential pressure. They are commonly installed in pipelines where accurate flow monitoring is essential for process control and system efficiency.
Vardhman Steel Overseas offers high-quality Orifice Flanges manufactured in compliance with ASTM, ASME, DIN, and EN standards. These flanges are available in Stainless Steel, Carbon Steel, Alloy Steel, Duplex, and Super Duplex with size ranges from ½” to 24” and pressure ratings of 150# to 2500#.
Orifice flanges are extensively used in oil & gas, chemical, power generation, water treatment, and refining industries. They provide a reliable, cost-effective method of measuring fluid flow while ensuring structural strength and leak-proof performance. Flanges are typically supplied with tapped holes, jack screws, and orifice plates upon request.
Choose Vardhman Steel Overseas for accurate, durable, and precisely machined Orifice Flanges that comply with international engineering standards and enhance operational efficiency in complex industrial systems.
