Orifice Flanges
Orifice Flanges are specialized pipe flanges designed for accurate flow measurement in piping systems using an orifice plate. Manufactured from premium quality materials, they provide excellent strength, durability, corrosion resistance, and reliable performance for oil & gas, petrochemical, chemical processing, power generation, refinery, and industrial applications.
Overview
Orifice Flanges are precision-engineered flanges used with orifice meters to measure the flow rate of liquids, gases, and steam in pipeline systems. They include pressure tapping points that allow accurate measurement of pressure differences across the orifice plate.
Manufactured using high-quality materials and advanced machining technology, Orifice Flanges offer excellent dimensional accuracy, mechanical strength, and reliable sealing performance. They are designed to withstand high-pressure and high-temperature operating conditions.
Veltronova Industries supplies premium quality Orifice Flanges in various sizes, pressure ratings, materials, and international standards. These flanges are widely used in oil & gas plants, refineries, petrochemical industries, power plants, chemical processing units, and process piping applications.
