Overview
Product overview
Orifice Flanges are indispensable components in pipelines and process industries, crucial for accurately measuring the flow of fluids. At Fortune Fittings Private Limited, we specialize in manufacturing and supplying high-quality Orifice Flanges designed to meet the demanding requirements of various industries, adhering to ANSI B 16.36 standards.
Understanding Orifice Flanges
Orifice flanges feature a specially designed hole or orifice plate, strategically installed within the flange. As fluids pass through this orifice plate, it creates a pressure differential, enabling precise flow measurement. These flanges are available in raised face (RF) and ring-type joint (RTJ) configurations, ensuring compatibility with diverse piping systems.
Installation and Operation
Proper installation of orifice flange assemblies is essential to ensure accurate flow measurement. Following manufacturer guidelines and industry standards is crucial for achieving optimal performance. Proper orientation and positioning of the orifice plate are imperative for accurate flow rate calculations.
Available Inventory
We maintain a ready inventory of orifice flanges in various sizes, ranging from 1 inch to 6 inches, ensuring prompt availability to meet our customers’ project requirements.
Conclusion
In conclusion, ASME B16.36 Orifice Flanges from Fortune Fittings Private Limited are essential components for precise flow measurement in piping systems across industries.
