ORIFICE FLANGES

Alloyed Sustainables LLP stands as a reputable manufacturer and exporter specializing in top-tier Orifice Flanges in India. Our comprehensive range of Orifice Flanges caters to diverse industries and is crafted from a variety of materials including Carbon Steel, Alloy Steel, Inconel, Stainless Steel, and more. Each flange is expertly manufactured in strict accordance with industry standards, ensuring precision, reliability, and compatibility. With our unwavering commitment to quality, we take pride in offering Orifice Flanges that facilitate accurate flow measurement and control across a wide spectrum of applications.

An orifice flange is used in piping systems, particularly in situations where flow rate measurement, control, or restriction is required. It features a circular plate with a centrally located hole or orifice through which fluids (liquids or gases) flow. These orifice flanges, conforming to ASME B16.36, can be manufactured from a diverse selection of materials, including carbon steel, alloy steel, stainless steel, and other suitable options. Orifice flanges are commonly available with Raised Faces or Ring Type Joint (RTJ) facings. The Threaded Class 300, Slip-on Class 300, and Welding Neck Classes 900, 300, 2500, 600, 400, and 1500 are the most frequently utilized orifice flanges according to ASME B16.36 standards.

Key Features of Orifice Flanges:

• Bolt Holes: Equipped with bolt holes around the edge to facilitate easy and secure attachment of the flanges.
• Pressure Tapping Points: These points allow for pressure measurement before and after the orifice plate to determine pressure differential.
• Flange Face Types: Offer different face types (RF, FF, RTJ) for effective sealing and compatibility with connecting flanges.
• Size and Pressure Ratings: Come in different sizes and pressure ratings to accommodate varying piping system needs.
• Orifice Plate Types: Different orifice plate types (concentric, eccentric, segmental) are chosen based on flow conditions and fluid properties.
• Flow Calibration: Orifice plates and flanges often undergo calibration to establish precise flow-rate-to-pressure-drop relationships.

Application across Industries:

• Oil and Gas: Orifice flanges are utilized in oil and gas pipelines to measure the flow of crude oil, natural gas, and refined products, enabling efficient production and distribution.
• Chemical Processing: In chemical plants, orifice flanges monitor the flow of different chemicals, aiding in precise dosing and ensuring safe and accurate mixing processes.
• Water Treatment: Orifice flanges play a key role in water treatment facilities by measuring the flow of water and various treatment chemicals, maintaining water quality standards.
• Power Generation: They are employed in power plants to measure steam flow, ensuring optimal energy generation while safeguarding equipment integrity.
• Automotive Manufacturing: Orifice flanges are employed to measure and control various fluids in automotive production processes, ensuring consistent quality.
• Marine and Shipping: Orifice flanges are used to measure fuel and fluid flow in ships and vessels, optimizing fuel efficiency and voyage planning.

We offer a wide selection of Orifice Flanges crafted from diverse materials and grades to perfectly suit the evolving needs of our clients and industries.
