An Orifice Flange is a specialized type of flange used to measure the flow rate of fluids or gases in a pipeline by means of an orifice plate.
Engineered for accuracy and durability, the Orifice Flange in Saudi is widely utilized in oil and gas, petrochemical, power, and industrial process plants across Riyadh, Dammam, Jeddah, Jubail, and Al-Khobar.
It provides a simple yet reliable method for monitoring flow, pressure, and differential pressure in various process applications.
An Orifice Flange is a pair of flanges with an orifice plate installed between them, designed specifically for flow measurement.
Each flange includes pressure tap holes (corner taps or flange taps) that allow connection to differential pressure transmitters.
By measuring the pressure drop across the orifice plate, engineers can calculate the flow rate with high accuracy.
This design eliminates the need for separate flow meters, making it an efficient and economical option for process control.
In Saudi Arabia’s energy and industrial sectors, precise flow monitoring and leak-proof operation are vital.
The Orifice Flange meets these demands by offering robust construction, precision engineering, and ASME-compliant performance.
Accurate Flow Measurement: Designed to provide precise differential pressure readings.
Standard Tappings: Equipped with corner, flange, or radius taps as per ASME B16.36.
Integrated Jack Screws: Simplifies orifice plate removal and replacement.
High Pressure Ratings: Suitable for both low and high-pressure systems.
Easy Maintenance: Orifice plate can cleaned or replaced without pipe disassembly.
Material Flexibility: Available in carbon steel, stainless steel, duplex, and alloy steel.
Compliance: Conforms to ASME B16.36, ASME B16.5, and API 6A standards.
